Yanxue Jia, HomeRun: High-efficiency Oblivious Message Retrieval, Unrestricted Nov 06, 2024

Oblivious Message Retrieval is designed to protect the privacy of users who retrieve messages from a bulletin board. Our work, HomeRun, stands out by providing unlinkability across multiple requests for the same recipient's address. Moreover, it does not impose a limit on the number of pertinent messages that can be received by a recipient, which thwarts "message balance exhaustion" attacks and enhances system usability. HomeRun also empowers servers to regularly delete the retrieved messages and the associated auxiliary data, which mitigates the constantly increasing computation costs and storage costs incurred by servers. Remarkably, none of the existing solutions offer all of these features collectively. About the speaker: Yanxue Jia is currently a post-doctoral researcher in the Department of Computer Science at Purdue University. In 2022, she obtained her Ph.D. in Computer Science from Shanghai Jiao Tong University. Her research mainly focuses on applied cryptography, especially secure computation, blockchain, and provable security. She is dedicated to designing efficient and secure cryptographic protocols that enhance collaboration while ensuring privacy protection. Her work has been published at top-tier conferences, such as USENIX Security, CCS, and Asiacrypt.

Roger Grimes, Many Ways to Hack MFA Oct 30, 2024

Students: this is a hybrid event. You are strongly encouraged to attend in-person. Location: STEW G52 (Suite 050B) WL Campus. Everyone knows that multi-factor authentication (MFA) is more secure than a simple login name and password, but too many people think that MFA is a perfect, unhackable solution. It isn't! I can send you a regular phishing email and completely take control of your account even if you use a super-duper MFA token or smartphone app. I can hack ANY MFA solution at least a handful of different ways, although some forms of MFA are more resilient than others. Attend this presentation and learn the 12+ ways hackers can and do get around your favorite MFA solution. The presentation will include a (pre-filmed) hacking demo and real-life successful examples of every attack type. It will end by telling you how to better defend your MFA solution so that you get maximum benefit and security. About the speaker: Roger A.

Alessandro Acquisti, Behavioral Advertising and Consumer Welfare Oct 23, 2024

Online behavioral advertising has raised privacy concerns due to its dependence on extensive tracking of individuals' behaviors and its potential to influence them. Those concerns have been often juxtaposed with the economic value consumers are expected to gain from receiving behaviorally targeted ads. Those purported economic benefits, however, have been more frequently hypothesized than empirically demonstrated. We present the results of two online experiments designed to assess some of the consumer welfare implications of behaviorally targeted advertising using a counterfactual approach. Study 1 finds that products in ads targeted to a sample of online participants were more relevant to them than randomly picked products but were also more likely to be associated with lower quality vendors and higher product prices compared to competing alternatives found among search results. Study 2 replicates the results of Study 1. Additionally, Study 2 finds the higher product relevance of products in targeted ads relative to randomly picked products to be driven by participants having previously searched for the advertised products. The results help evaluate claims about the direct economic benefits consumers may gain from behavioral advertising. About the speaker: Alessandro Acquisti is the Trustees Professor of Information Technology and Public Policy at Carnegie Mellon University's Heinz College. His research combines economics, behavioral research, and data mining to investigate the role of privacy in a digital society.

Michail Maniatakos, Dissecting the Software Supply Chain of Modern Industrial Control Systems Oct 02, 2024

Recent years have been pivotal in the field of Industrial Control Systems (ICS) security, with a large number of high-profile attacks exposing the lack of a design-for-security initiative in ICS. The evolution of ICS abstracting the control logic to a purely software level hosted on a generic OS, combined with hyperconnectivity and the integration of popular open source libraries providing advanced features, have expanded the ICS attack surface by increasing the entry points and by allowing traditional software vulnerabilities to be repurposed to the ICS domain. In this seminar, we will shed light to the security landscape of modern ICS, dissecting firmware from the dominant vendors and motivating the need of employing appropriate vulnerability assessment tools. We will present methodologies for blackbox fuzzing of modern ICS, both directly using the device and by using the development software. We will then proceed with methodologies on hotpatching, since ICS cannot be easily restarted in order to patch any discovered vulnerabilities. We will demonstrate our proposed methodologies on various critical infrastructure testbeds. About the speaker: Michail (Mihalis) Maniatakos is an Associate Professor of Electrical and Computer Engineering at New York University (NYU) Abu Dhabi, UAE, and a Research Associate Professor at the NYU Tandon School of Engineering, New York, USA.

Chance Younkin, Shamrock Cyber – When Luck Just Isn't Enough Sep 25, 2024

In the past 30 years, the world has experienced a booming IoT market, advances in automation and OT systems, and an ever-increasing dependence on cyber in every aspect of modern life. This target rich environment is ideal for cyber adversaries seeking access to systems and devices for financial gain, espionage, digital harassment, or outright cyber-warfare. Naturally, this leads to expanded attack surfaces, increased risk, and a complex and costly cyber arms race.By combining consequences, threats, and vulnerabilities and mapping them to mission risk, Shamrock Cyber significantly reduces the effort to prioritize, communicate, and mitigate risk. The Shamrock approach enables defenders to focus on their domains and yet understand and operate based on the domains of others. Through 4 kinds of analysis—Consequence, Threat, Vulnerability, and Risk, there are multiple approaches to suit the needs of many missions. Shamrock Cyber uniquely blends traditionally effective activities with innovative mission focused analyses that unite the equities of executives, managers, cyber practitioners, and system developers.Shamrock Cyber does not depend on leprechauns and luck to find cybersecurity gold at the end of the rainbow. Instead, it focuses on combining consequences, threats, and vulnerabilities, to communicate and reduce mission risk along with explaining the WHY to all involved.

Russel Waymire, IDART (Information Design Assurance Red Team): A Red Team Assessment Methodology Sep 11, 2024

The Information Design Assurance Red(IDART) methodology is optimized to evaluate system designs and identify vulnerabilities by adopting, in detail, the varying perspectives of a system's most likely adversaries. The results provide system owners with an attacker's-eye view of their system's strengths and weaknesses.IDART can be applied to a diversity of complex networks, systems, and applications, including those that mix cyber technology with industrial machinery or other equipment. The methodology can be used throughout a system's lifecycle but the assessments are less expensive and more beneficial during design and development, when weaknesses can be found and mitigated more easily.Developed at Sandia National Laboratories in the mid-1990s and updated frequently, the IDART framework is NIST-recognized and designed for repeatability and measurable results. Atypical assessment includes the following high-level activities:Characterizing the target system and its architectureIdentifying nightmare consequencesAnalyzing the system for security strengths and weaknessesIdentifying potential vulnerabilities that could lead to nightmare consequencesDocumenting results and providing prioritized mitigation strategiesIDART assessors think like adversaries. To do this, they first develop a range of categorical profiles or"models" of a system's most likely attackers. Factors include an adversary's specific capabilities (i.e., domain knowledge, access, resources) as well as intangibles such as motivation and risk tolerance. The assessment team then uses this adversarial lens to measure the risks posed by system weaknesses and to prioritize mitigations.For efficiency and thoroughness, IDART relies on a free exchange of information. System personnel share documentation and participate in discussions that help assessors efficiently find as many attack paths as possible. In turn, the IDART team is transparent in conducting its assessment activities, giving system owners greater confidence in the work and the resulting analysis.All of these traits combine to make IDART a highly flexible tool. The methodology helps system owners identify critical vulnerabilities, understand adversary threats, and weigh appropriate strategies for delivering components, systems, and plans that are botheffective and secure. About the speaker: Russel Waymire is a manager at Sandia National Laboratories in the area of Cyber-Physical Security. Mr. Waymire has over 25 years of experience in the design, implementation, testing, reverse engineering, and securing of software and hardware systems in IT and OT environments.

Shagufta Mehnaz, Privacy and Security in ML: A Priority, not an Afterthought Aug 21, 2024

The increased use of machine learning (ML) technologies on proprietary and sensitive datasets has led to increased privacy breaches in many sectors, including healthcare and personalized medicine. Although federated learning (FL) systems allow multiple parties to train ML models collaboratively without sharing their raw data with third-party entities, security concerns arise from the involvement of potentially malicious FL clients aiming to disrupt the learning process. In this talk, I will present how my research addresses these challenges by developing frameworks to analyze and improve the privacy and security aspects of ML. First, I will talk about model inversion attacks that allow an adversary to infer part of the sensitive training data with only black-box access to a vulnerable classification model. I will then present FLShield, a novel FL framework that utilizes benign data from FL participants to validate the local models before taking them into account for generating the global model. I will conclude with a discussion of challenges in building practical data-driven systems that take into account data privacy and security while keeping the intended functionality of the system unimpaired.

Evan Sultanik, In Pursuit of Silent Flaws: Dataflow Analysis for Bugfinding and Triage Apr 10, 2024

In this presentation, I provide a thorough exploration of how dataflow analysis serves as a formidable method for discovering and addressing cybersecurity threats across a wide spectrum of vulnerability types. For instance, I'll illustrate how we can employ dynamic information flow tracking to automatically detect "blind spots"—sections of a program's input that can be changed without influencing its output. These blind spots are almost always indicative of an underlying bug. Furthermore, I will demonstrate how the use of hybrid control- and dataflow information in differential analysis can aid in uncovering variability bugs, commonly known as "heisenbugs." By delving into these practical applications of dataflow analysis and introducing open-source tools designed to implement these strategies, the goal is to present practical steps for pinpointing, debugging, and managing a diverse array of software bugs. About the speaker: Dr. Evan Sultanik is a principal computer security researcher at Trail of Bits. His recent research covers language-theoretic security, program analysis, detecting variability bugs via taint analysis, dependency analysis via program instrumentation, and consensus protocols for distributed ledgers. He is an editor of and frequent contributor to the offensive computer security journal "Proof of Concept or GTFO." Prior to joining Trail of Bits, Dr. Sultanik was the Chief Scientist at Digital Operatives and, prior to that, a Senior Research Scientist at The Johns Hopkins Applied Physics Laboratory. His dissertation was on the discovery of a family of combinatorial optimization problems the solutions for which can be approximated constant factor of optimal in polylogarithmic time on a parallel computer or distributed system. This was a surprising result since many of the problems in the family are NP-Hard. In a life prior to academia, Evan was a professional software engineer.

Daniel Shoemaker, Secure Sourcing of COTS Products: A Critical Missing Element in Software Engineering Education Mar 27, 2024

The aim of this discussion is to publicize both the challenge and potential solution for the integration of secure supply chain risk management content into conventional software engineering programs. The discipline of software engineering typically does not teach students how to ensure that the code produced and sold in commercial off-the-shelf (COTS) products hasn't been compromised during the sourcing process. We propose a comprehensive and standard process based on established best practice principles that can provide the basis to address the secure sourcing of COTS products. About the speaker: Dr. Dan Shoemaker received a doctorate from the University of Michigan in 1978. He taught at Michigan State University and then moved to the Business School at the University of Detroit Mercy to Chair their Department of Computer Information Systems (CIS). He attended the organizational roll-out of the discipline of software engineering at the Carnegie-Mellon University Software Engineering Institute in the fall of 1987. From that, he developed and taught a SEI-based software engineering curriculum as a separate degree program to the MBA within the College. During that time, Dr. Shoemaker's specific areas of scholarship, publication, and teaching centered on the processes of the SWEBOK, specifically specification, SQA, and SCM/sustainment. Dr. Shoemaker's transition into cybersecurity came after UDM was designated the 39th Center of Academic Excellence by the NSA/DHS at West Point in 2004. His research concentrated on the strategic architectural aspects of cybersecurity system design and implementation, as well as software assurance. He was the Chair of Workforce Training and Education for the DHS/DoD Software Assurance initiative (2007-2010), and he was one of the three authors of the Common Body of Knowledge to Produce, Acquire, and Sustain Software (2006).

His latest book, "Teaching Cyber Security" (Taylor and Francis), is aimed at K-12 teachers.

Douglas Huelsbeck, The Importance of Security by Design & The Importance of Including Cybersecurity Experts in Your Business Decisions Mar 20, 2024

How Cybersecurity relates to various fields of business/ industries – how it works in these fields, different risks and vulnerabilities that are out there, which explains why manufacturing cybersecurity into the design of a product or service is so imperative. In companies today Budget Managers and Business Managers and Engineers are making decisions on their cybersecurity options without including cybersecurity experts in that process. Without the input from the cybersecurity experts, some cybersecurity decisions are made with cost savings as the primary goal, and cutting corners in cybersecurity can actually be a bad idea.

Alejandro Cuevas, The Fault in Our Stars: How Reputation Systems Fail in Practice Mar 06, 2024

Reputation systems are crucial to online platforms' health. They are prevalent across online marketplaces and social media platforms either visibly (e.g., as star ratings and badges) or invisibly as signals that feed into recommendation engines. In theory, good behavior (e.g., honest, accurate, high-quality) begets high reputation, while poor behavior is deterred and pushed off the platform. In this talk, I will discuss how these systems seem to fulfill this mission only coarsely. On one platform, we were able to predict 2 times more suspensions than the reputation system in place using other public signals. On another study, we found that users with high reputation signals were suspended at significantly lower rates (up to 3 times less) for the same number of offenses and behavior as regular users, which suggests they may be impairing content moderation efforts. I will provide some hypotheses to explain these results and offer preliminary findings from current work. About the speaker: Alejandro is a 5th year PhD student at Carnegie Mellon University in Societal Computing, advised by Prof. Nicolas Christin. He is interested in measuring social influence in online communities adjacent to underground economies. His recent work focuses on how reputation is leveraged in anonymous marketplaces, p2p marketplaces, and cryptocurrency communities. He is a recipient of a CMU Cylab Presidential Fellowship, as well as a IEEE S&P Distinguished Paper Award. Prior to CMU, he obtained a B.S. from The Pennsylvania State University, where he worked with Prof. Peng Liu and Prof. Xinyu Xing on a variety of systems security projects. A Paraguayan native, Alejandro has been invited to talk about his work at the Paraguayan Central Bank and the Paraguayan National Police.

Jennifer Bayuk, Stepping Through Cybersecurity Risk Management A Systems Thinking Approach Feb 21, 2024

In the realm of risk, cybersecurity is a fairly new idea. Most people currently entering the cybersecurity profession do not remember a time when cybersecurity was not a major concern. Yet at the time of this writing, reliance on computers to run business operations is less than a century old. Prior to this time, operational risk was more concerned with natural disasters than man-made ones. Fraud and staff mistakes are also part of operational risk, so as dependency on computers steadily increased from the 1960s through the 1980s, a then-new joke surfaced: To err is human, but if you really want to screw things up, use a computer.Foundational technology risk management concepts have been in place since the 1970s, but the tuning and the application of these concepts to cybersecurity were slow to evolve. Yet there is no doubt that cybersecurity risk management tools and techniques have continuously improved.. Although the consequences of cybersecurity incidents have become dramatically more profound over the decades, available controls have also become more comprehensive, more ubiquitous, and more effective. This seminar is intended to make the fundamentals of cybersecurity risk management visible to those who are contributing to it, and comprehensible to those looking in from the outside.

Mu Zhang, Backtracking Intrusions in Modern Industrial Internet of Things Dec 06, 2023

Advanced Persistent Threat (APT) attacks are increasingly targeting modern factory floors. Recovery from a cyberattack is a complex task that involves identifying the root causes of the attack in order to thoroughly cleanse the compromised systems and remedy all vulnerabilities. As a result, the provenance analysis, which can correlate individual attack footprints and thus "connect the dots", is very much desired. Provenance analysis has been well studied in traditional IT systems, yet the OS-level attack model, prior work employs, cannot effectively capture application semantics in physical control systems. Recent efforts have been made to develop custom provenance models that uniquely represent physical attacks in cyber-physical systems. Nevertheless, existing techniques still fall short due to their unreliable semantic recovery, inability to reconstruct process contexts, and lack of cross-domain causality tracking. In this talk, we present ICSTracker, which aims to enable provenance analysis in the new setting of industrial IoT. To recover the physical semantics of controller routines, we utilize data mining to identify function call sequences that align with specific physical actions. To establish the process contexts, we resort to the data access patterns in controller code to discover and keep track of critical state variables that are shared among multiple iterations of control logic. To uncover the methods attackers employ in exploiting digital vulnerabilities to cause physical damage, we perform a cross-domain causality analysis, associating controller operations with OS-level events through their mutual access to shared digital assets. We have implemented and tested ICSTracker in a FischerTechnic testbed. Our preliminary results are promising, demonstrating that ICSTracker can precisely capture cross-domain cyber-physical attacks in a semantics and context-aware fashion. About the speaker: Mu Zhang is an Assistant Professor with the Kahlert School of Computing at the University of Utah. Zhang works at the unique intersection between systems security and cyber-physical systems.

Robert Denz, Mind the Gap: Vulnerabilities and Opportunities for Cyber R&D at the Edge Nov 29, 2023

This is a hybrid event. Students are encouraged to attend in person: STEW G52(Suite 050B) Commercial or defense systems are often developed first to meet a mission or customer need. Security of many of these systems is often developed at a component level by each components product team. The product teams often maintain robust security for their component within the system, but security gaps begin to form when the complete system is assembled. Adversaries will seek to exploit these gaps in the overall system design as they look for the path of least resistance to achieve their goals. These adversaries do not limit themselves to one exploitation domain and will often pivot across domains in their execution of an attack. To guard against these multi-domain threats, we as security practitioners and researchers need to work together to adjust our world view on the larger system of system security challenge that we face. This presentation begins the process of enumerating some of these gaps, how gaps came into existence, and provides potential research avenues to address them. About the speaker: Dr. Robert Denz serves as the Director of the Secure and Resilient Systems group at Riverside Research. In this role, he leads a team of researchers who ensure software provenance, security, reliability, and resilience in systems. To achieve these objectives, the Secure and Resilient Systems group conducts innovative research in formal methods, AI-driven secure waveform design, and secure operating system implementations for the Department of Defense (DoD) and Intelligence Community (IC).Dr. Denz has over 15 years of experience working on and leading cybersecurity and anti-tamper research programs for DARPA and the DoD. He was recently the Principal Investigator for DARPA Dispersed Computing, where he oversaw a multi-disciplinary team that delivered distributed resilient mesh routing protocols to the tactical edge.

Dr. Denz received his PhD in secure hypervisor and kernel design from the Thayer School of Engineering at Dartmouth College in 2016.

Andy Ellis, How to Build and Measure a Corporate Security Program Nov 15, 2023

The challenge of building a security program is that there are too many things you could be doing, and that creates a challenge for security leaders to decide on which things they should do next.All too often companies pivot from fighting one fire to another fire. They end up cobbling together a security program with duct tape, bailing wire, and a handful of solutions implemented as a reaction to our own incidents and major headlines about other companies' breaches. How should a CISO evaluate building their security program?In this talk, I will be exploring a mental model that CISOs can use - that I used in my 20 years as a CISO - to evaluate the state of their security program, and to identify where there are gaps in coverage. At a high level, the framework is four dimensional, covering width (asset coverage), height (control comprehensiveness), depth (risk context), and time (maturity continuity). I will use case studies to highlight ways the security programs often fail on one of these axes, as a means for participants to connect the programs they work on to the shortcomings others have already experienced.Most ways to evaluate a security program become frameworks with an overly strong focus on detail, but which lose the holistic view of the health of a security program, and even the "known unknowns" (we're pretty sure there is a risk, but don't have specifics) become forgotten as the focus narrows to the "known knowns" (we've documented the risk). The "unknown unknowns," of course, almost never get visibility.Combining a mental model for assessing the overall maturity of the program, with a high level risk comparison system (the "Pyramid of Pain") allows a CISO to identify areas for improvement to mitigate risk in the future.Case studies from my time at Akamai will be shared (demonstrating not only how to quickly assess risk, but how to understand risk areas that may take years to mitigate), including the risk areas whose mitigation helped propel Akamai into the security leviathan it is today. About the speaker: Andy Ellis is a seasoned technology and business executive with deep expertise in cybersecurity, managing risk, and leading an inclusive culture. He is the founder and CEO of Duha, a boutique advisory firm focused on providing strategic consulting in the areas of Leadership, Management, Cybersecurity, Technology Risk, and Enterprise Risk Management.

Steve Lipner, Thinking About the Future of Encryption Nov 01, 2023

During the last several years, there has been growing concern that the development of quantum computers could undermine the public-key cryptography that is a fundamental pillar of security on the Internet. Recently, the U.S. Government's National Institute of Standards and Technology has released draft standards for post-quantum encryption algorithms that can replace the existing, and potentially vulnerable public-key encryption. But while the future of encryption will depend on new algorithms,there are many other factors that will influence security in the decades to come. In 2022, the National Academies of Sciences, Engineering, and Medicine released a report on "The Future of Encryption" that examines factors including technical aspects of cryptography, societal and policy considerations, and product engineering. The report presents a series of findings that apply broadly, and paints three alternative future scenarios for the future of encryption. This presentation, based largely on the Academies report, will provide researchers, engineers, and policy professionals with context in which to view future developments and concepts for prioritizing future actions.

Derek Dervishian, Fuzzing: Understanding the Landscape Oct 18, 2023

The number of software vulnerabilities found in modern computing systems has been on the rise for some time now. As more and more software is being developed, software testing is increasingly becoming an important part of the software development cycle, with the goal of rooting out any and all vulnerabilities before public release. However, finding software vulnerabilities is not a trivial task, especially in complex software systems with thousands of lines of code and complicated system interactions. Just a single vulnerability making its way into a software product/service can have devastating consequences, if not discovered and patched in good time.Luckily, there is a plethora of available software testing tools and techniques. One such software testing approach is called fuzzing. Fuzzing is an automated program testing technique introduced in the late-1980s, and has become a critical tool in a software tester's toolkit. Fuzzing is based on the simple idea of feeding software lots of mutated inputs and monitoring the program state for any anomalous behavior. Fuzzers have had a long and successful track record of finding software vulnerabilities. This success brought forth new and innovative approaches to improve the overall fuzzing process in all aspects. However, despite its success and widespread use, fuzzing is not a "one size fits all" approach. Software testers still have to tailor their fuzzing methodology to the software under test. Therefore, understanding the inner workings of fuzzers is absolutely vital in order to determine when and how to use them most effectively. About the speaker: Derek Dervishian works as a cybersecurity research engineer at Lockheed Martin - Advanced Technology Laboratories, an advanced applied R&D division of the Lockheed Martin corporation, specializing in cyber, autonomy, data analytics and much more. In this role, Derek has worked on several R&D projects across multiple technical areas, including vulnerability research and binary analysis.Derek graduated from Purdue University with a Bachelor's degree in Computer Engineering in December 2020.

Rebecca Herold, Sorting Surveillance Benefits from Harms Oct 11, 2023

Tracking technologies are proliferating at an increasingly high rate in apps, IoT devices, websites, and in a wide range of files. They are not only impacting privacy in wider and more harmful ways, but they have also extended far beyond the digital world and are also impacting physical safety. Such tools can certainly be very beneficial, when used responsibly and with informed awareness of the cybersecurity and privacy risks. However, when they are used without establishing technical and non-technical boundaries, and without taking risk mitigation actions, the associated surveillance activities can, and have, brought physical harms. I was an expert witness for a case a couple of years ago involving a stalker's use of his victim's smart car to find and almost fatally assault her. I'm currently an expert witness for two separate cases involving the use of Meta Pixels, Conversion APIs, cookies, and other types of tracking tech for surveillance of online activities. Virtually daily there are news articles reporting privacy invasions by digital trackers, drones, security cameras, and more. I will provide several real-life use cases, and provide discussion for the technical and non-technical capabilities that possibly could have been identified through risk assessment activities prior to making such products publicly available and informed the needed associated security and privacy capabilities, that would have supported privacy and cybersecurity protections and physical safety. About the speaker: Rebecca Herold has over 30 years of security, privacy and compliance experience. She is founder of The Privacy Professor Consultancy (2004) and of Privacy & Security Brainiacs SaaS services (2021) and has helped hundreds of clients throughout the years. Rebecca has been a subject matter expert (SME) for the National Institute of Standards and Technology (NIST) on a wide range of projects since 2009, including: 7 ½ years leading the smart grid privacy standards creation initiative, and co-authoring those informative references and standards; 2 years being a co-author of and a SME member of the team that created the Privacy Framework (PF) and associated documents; and 3 years as a SME team member, and co-author of the internet of things (IoT) technical and non-technical standards and associated informative references; and performing throughout the years proof of concept (PoC) tests for a variety of technologies, such as field electricity solar inverters, PMU reclosers, and associated sensors. Rebecca has served as an expert witness for cases covering HIPAA, privacy compliance, criminals using IoT devices to track their victims, stolen personal data of retirement housing residents, tracking app and website users via Meta Pixels and other tracking tech, and social engineering using AI. Rebecca has authored 22 books, and was adjunct professor for 9 ½ years for the Norwich University MSISA program. Since early 2018 Rebecca has hosted the Voice America podcast/radio show, Data Security & Privacy with the Privacy Professor. Rebecca is based in Des Moines, Iowa, USA. www.privacysecuritybrainiacs.com

Khaled Serag, Vulnerability Identification and Defense Construction in Cyber-Physical Systems Oct 04, 2023

With the ever-accelerating computerization process of once strictly mechanical systems, information security threats are only expected to increase. This rapidly unfolding process calls into question whether we could promptly cope with the security threats it entails. Unfortunately, a commonly observed trend is for the computerization process to steadily advance while paying little attention to the security aspect until a security vulnerability is discovered, often by an external actor. Only then, a quest for a suitable security measure begins. In sum, security is considered only in reaction to manifest breaches. This comes at a high price, as the fix is not often found speedily after the breach. In this talk, I will explain how to take a proactive vulnerability identification and defense construction approach to better secure cyber-physical systems. I will discuss two main themes of my research: 1) vulnerability identification and 2) defense construction with a focus on the context of Controller Area Network (CAN) systems. About the speaker: Dr. Khaled Serag is a post-doctoral research assistant at Purdue University. He finished his Ph.D. at Purdue in August 2023. His broad research area is Information Security.

This incident underscored the imperative for innovative approaches to ensure software artifacts' integrity and authenticity. The Supply Chain Level for Software Artifacts (SLSA)framework emerged as a response, emphasizing secure software development processes for supply chains. As compliance standards, notably enforced by the National Institute of Standards and Technology (NIST), intensify the call for robust security measures, the convergence of open-source technologies presents a compelling solution.In the contemporary landscape of distributed systems, like Kubernetes, the significance of signing critical artifacts, such as container images and builds, cannot be overstated. These signatures substantiate the origin and unaltered state of the artifacts, rendering them resistant to tampering or unauthorized access. Yet, with the escalating complexity of software supply chains, bolstered by the proliferation of distributed technologies, ensuring trustworthy artifact provenance becomes more formidable.This challenge is where SigStore, an innovative technology solution, steps in. SigStore enables cryptographic signing and verification of software artifacts, offering a robust mechanism to establish the authenticity of these components. By leveraging transparency log technologies, SigStore enhances the trustworthiness of the supply chain,creating a formidable barrier against malicious alterations.This talk will discuss the popular technologies in the industry that are utilizing a zero trust software supply chain. Why this type of supply chain is important, and outline the different technologies used in conjunction with SigStore to create zero-trust supply chains within the software development and deployment lifecycle.Christopher Nuland has been involved with container technology since 2010, when he worked with Oak Ridge Labs and Purdue's CdmHub on containerizing their simulations with OpenVZ.

Stuart Shapiro, MITRE PANOPTIC™ Privacy Threat Model Sep 13, 2023

As privacy moves from a predominantly compliance-oriented approach to one that is risk-based, privacy risk modeling has taken on increased importance. While a variety of innovative pre-existing options are available for privacy consequences and a few for vulnerabilities, privacy threat models, particularly ones focused on attacks (as opposed to threat actors) remain relatively scarce. To address this gap and facilitate more sophisticated privacy risk management of increasingly complex systems, MITRE has developed the Pattern and Action Nomenclature Of Privacy Threats In Context (PANOPTIC™). By providing an empirically-driven taxonomy of privacy threat activities and actions – as well as contextual elements – to support environmental and system-specific threat modeling, PANOPTIC is intended to do for privacy practitioners what MITRE ATT&CK® has done for security practitioners. This presentation discusses the underpinnings and provides an overview of PANOPTIC and its use. About the speaker: Stuart S. Shapiro is a Principal Cyber Security and Privacy Engineer and a co-leader of the Privacy Capability in the MITRE Labs Cyber Solutions Innovation Center at the MITRE Corporation. At MITRE he has led multiple research and operational efforts in the areas of privacy engineering, privacy risk management, and privacy enhancing technologies (PETs), including projects focused on connected vehicles and on de-identification. He has also held academic positions and has taught courses on the history, politics, and ethics of information and communication technologies. His professional affiliations include the International Association of Privacy Professionals (IAPP) and the Association for Computing Machinery (ACM).

Patrick Schlapfer, Using Endpoint Isolation to Track Malware Trends Mar 08, 2023

Endpoint security controls have traditionally relied on detecting malicious activity to protect devices from intrusions. But attackers often change their techniques so quickly that detection patterns must be adapted, resulting in a detection lag. Some of this limitation can be solved by using hardware-based process isolation, which isolates risky endpoint tasks from the user's data and critical parts of the operating system. One of the most interesting data sources the HP Threat Research team uses to track malware trends and behaviors are isolation traces, since they can give us an insight into techniques that have bypassed detection controls. In this presentation, we provide an overview of captured attack techniques that are currently seen in the wild. We will elaborate how attackers try to bypass email security and how users are lured to infected websites to download malware. Finally, we will share advice on how to protect against such attacks and what to look out for. About the speaker: Patrick is a malware analyst at HP with interests in a wide range of security areas. He already focused on cyber security during his studies, where he developed a particular interest in malware analysis. After graduation, he worked on a scientific project at the university and built a dynamic malware analysis system for code similarity clustering.

He conducts analyses of new threats, using the results to improve HP's security products and shares them with the community.

Albert Cheng, Elements of Robust Real-Time Systems: Regularity-Based Virtualization and Functional Reactive Programming Mar 01, 2023

The use of sophisticated digital systems to control complex physical components in real-time has grown at a rapid pace. These applications range from traditional stand-alone systems to highly-networked cyber-physical systems (CPS), spanning a diverse array of software architectures and control models. Examples include city-wide traffic control, robotics, medical systems, autonomous vehicular travel, green buildings, physical manipulation of nano-structures, and space exploration. Since all these applications interact directly with the physical world and often have humans in the loop, we must ensure their robustness, security, and physical safety. Obviously, the correctness of these real-time systems and CPS depends not only on the effects or results they produce, but also on the time at which these results are produced. For instance, in a CPS consisting of a multitude of vehicles and communication components with the goal to avoid collisions and reduce traffic congestions, formal safety verification and response time analysis are essential to the certification and use of such systems. This seminar introduces two key elements for building robust real-time systems: regularity-based virtualization and functional reactive programming.Real-time resource partitioning (RP) divides hardware resources (processors, cores, and other components) into temporal partitions and allocates these partitions as virtual resources (physical resources at a fraction of their service rates) to application tasks. RP can be a layer in the OS or firmware directly interfacing the hardware, and is a key enabling technology for virtualization and cloud computing. Open, virtualized real-time systems make it easy to securely add and remove software applications as well as to increase resource utilization and reduce implementation cost when compared to systems which physically assign distinct computing resources to run different applications. The first part of this talk will describe ways based on the Regularity-based Resource Partition Model (RRP) to maintain the schedulability of real-time tasks as if they were scheduled on dedicated physical resources and increase the utilization of the physical multi-resources.The benefits of using the functional (reactive) programming (FRP) over the imperative programming style found in languages such as C/C++ and Java for implementing embedded and real-time software are several. The functional programming paradigm allows the programmer to intuitively describe safety-critical behaviors of the system and connect its components, thus lowering the chance of introducing bugs in the design phase, resulting in a robust and secure implementation. Its stateless nature of execution does not require the use of synchronization primitives like mutexes and semaphores, thus reducing the complexity in programming on parallel and multi-core platforms. Hence, FRP can potentially transform the way we implement next-generation real-time systems and CPS. However, accurate response time analysis of FRP-based controllers remains a largely unexplored problem. The second part of this talk will explore a framework for accurate response time analysis, scheduling, and verification of embedded controllers implemented in FRP.

Arjan Durresi, Trust Engineering – from Developing Resilient Systems to Artificial Conscience Feb 22, 2023

This talk will discuss how we engineer trust among agents, humans, and algorithms to develop solutions to significant practical problems, including Trustworthy AI in multiple applications, Resilience in systems, and a framework for Artificial Conscience to control AI, which we extend to system security. Trustworthiness of AI solutions is emerging as a must for the best use of AI. Using our trust system, we have developed metrics for acceptance, explainability, and fairness of AI solutions having humans in the loop. Furthermore, we introduce the concept of Trustability, which captures the probability of a system keeping the required QoS performance under a specific attack tree. Finally, we present our framework for Artificial Conscience, where AI algorithms are controlled by agents who negotiate with each other using our trust engine to output a solution with maximum" Artificial Feeling." This framework can be easily implemented in any AI system where multiple metrics are involved, including system security scenarios.

Mummoorthy Murugesan, Problems and Challenges in Data Security Posture Management Jan 18, 2023

The rise of enterprise cloud computing has brought an even greater emphasis on data. According to an analysis compiled by Statista, two zettabytes of data were created, captured, copied, and consumed globally in 2010. That figure will reach 97 zettabytes this year and 181 zettabytes by 2025. As the adoption of cloud computing continued to evolve, so did how enterprises approached securing their data. Today, enterprises find their data scattered throughout their various cloud systems, and they have lost visibility into where their sensitive data resides. The problems are about whether there are any shadow data stores that developers left abandoned? Who can access all of the enterprise data on these clouds, and are there excessive privileges? What data is at risk of being breached and falling out of regulatory compliance? Moreover, the growing complexity of cloud computing is a big part of why breached data records have risen (according to the Identity Theft Resource Center) from 16 million in 2010 to more than 155 million today. A recent survey from IDC found that 98% of organizations they queried reported at least one cloud data breach in the past 18 months. With all these challenges, cybersecurity professionals are faced with the daunting task of understanding where their organization's critical or regulated data exists across cloud platforms. The process of identifying and securing cloud data is called the Data Security Posture Management. In this talk, we will go over certain techniques for discovering, analyzing and securing data in various cloud platforms. We will then look at challenging problems that are opening up more avenues for further investigation, and research. About the speaker: Dr. Mummoorthy Murugesan is currently the founding Director of Engineering at Normalyze Inc. Earlier, he worked at Teradata R&D where he developed the incremental planning and execution of queries. He has worked in start-ups such as Netskope, and Turn to build highly scalable systems.

Dr. Murugesan's interests span data, analytics, security and cloud infrastructure. He received his Ph.D. in Computer Science from Purdue University, and Masters degree from Syracuse University.

Ambrose Kam, Applying Multi-Agent Reinforcement Learning (MARL) in a Cyber Wargame Engine Jan 11, 2023

Cybersecurity is inherently complicated due to the dynamic nature of the threats andever-expanding attack surfaces. Ironically,this challenge is exacerbated by the rapid advancement of many new technologieslike Internet of Things (IoT) devices, 5G infrastructure, cloud-basedcomputing, etc. This is where artificialintelligence (AI) and machine learning (ML) techniques can be called intoservice, and provide potential solutions in terms of threat detection andmitigation responses in a rapidly changing environment. On contrary, humans are often limited by theirinnate inability to process information and fail to recognize/respond to attackpatterns in the multi-dimensional, multi-faceted world. The recent DARPA AlphaDogFight has proven AIpilots can defeat even the best human pilot in air-to-air combat. This prompted our engineers to develop aminimum viable product (MVP) that demonstrates the value of a multi-agent reinforcementlearning (MARL) architecture in a simulated cyber wargaming environment. By using our simulation framework, we essentially"trained" the learning agents to produce the optimum combination/permutation ofcyber attack vectors in a given scenario. This cyber wargaming engine allows our analysts to examine tactics,techniques and procedures (TTPs) potentially employed by our adversaries. Once these vulnerabilities are analyzed, ourcyber protection team (CPT) can close security gaps in the system. About the speaker: Ambrose Kam is a Lockheed Martin Fellow with over 25 years of experience in the Department of Defense (DoD) industry. He is one of the earliest pioneers at applying modeling, simulation, and operations analysis techniques to threat modeling and cyber resiliency assessment.

Brian Barnier & Prachee Kale, Making Cybersecurity Reliable and Cybersecurity Careers Rewarding Nov 16, 2022

People face increasing dangers from cyber enemies. At the same time, cyber pros are suffering from stress, burnout and "hamster wheel"syndrome. They experience many difficulties every day in easily protecting people and companies from danger.There is a different option. Cyber pros have the opportunity of better work-life balance, more rewarding careers and achieving their personal missions to better protect people and companies – by making cybersecurity as reliable as electricity. How? The same way as other business functions do – with curiosity,critical thinking, system thinking and industrial-strength design thinking. The same way business innovation created products that delight us in daily life.The same way music, sports and cooking bring us joy. The same way military battles are won. It takes learning to think counter intuitively and to change. But there's a twist, business innovators have education,method and coaching at the individual, team and organizational levels.Compared to other business functions, cyber pros are setup to fail. The support system for cyber pros is missing!The good news is, it's readily fixable! That starts with putting people in the center of cybersecurity – empowering cyber pros to more easily protect people from danger, accelerating authentic Zero Trust and making cybersecurity as reliable as electricity.

Christine Task, Data, Privacy---and the Interactions Between Them Nov 09, 2022

Data deidentification aims to provide data owners with edible cake: to allow them to freely use, share, store and publicly release sensitive record data without risking the privacy of any of the individuals in the data set. And, surprisingly, given some constraints, that's not impossible to do. However, the behavior of a deidentification algorithm depends on the distribution of the data itself. Privacy research often treats data as a black box---omitting formal data-dependent utility analysis, evaluating over simple homogeneous test data, and using simple aggregate performance metrics. As a result, there's less work formally exploring detailed algorithm interactions with realistic data contexts. This can result in tangible equity and bias harms when these technologies are deployed; this is true even of deidentification techniques such as cell-suppression which have been in widespread use for decades. At worst, diverse subpopulations can be unintentionally erased from the deidentified data. Successful engineering requires understanding both the properties of the machine and how it responds to its running environment. In this talk I'll provide a basic outline of distribution properties such as feature correlations, diverse subpopulations, deterministic edit constraints, and feature space qualities (cardinality, ordinality), that may impact algorithm behavior in real world contexts. I'll then use new (publicly available) tools from the National Institute of Standards and Technology to show unprecedentedly detailed performance analysis for a spectrum of recent and historic deidentification techniques on diverse community benchmark data. We'll combine the two and consider a few basic rules that help explain the behavior of different techniques in terms of data distribution properties. But we're very far from explaining everything—I'll describe some potential next steps on the path to well-engineered data privacy technology that I hope future research will explore. A path I hope some CERIAS members might join us on later this year. This talk will be accessible to anyone who's interested—no background in statistics, data, or recognition of any of the above jargon is required. About the speaker: Christine Task is a CERIAS alumna, who earned her PhD in Computer Science at Purdue University in 2015, and joined Knexus Research Corporation later that year. Since then she has led the first National Challenges in Differential Privacy for the National Institute of Standards and Technology, contributed to 2020 Census Differentially Private Disclosure Avoidance System, served as technical lead for non-DP Synthetic Data projects for the US Census Bureau's American Community Survey, American Housing Survey and American Business Survey, been co-lead on the United Nation's UNECE Synthetic Data Working Group, and led the development of the SDNist data deidentification benchmarking library. Back in 2012, as a doctoral student at Purdue, she gave a CERIAS seminar titled "Practical Beginner's Guide to Differential Privacy", whose success was very valuable to her career. Having begun a decade ago, she was thrilled to be invited back to present what amounts to an update on that work.

Ning Zhang, Security and Privacy in the Cyber-physical World Oct 26, 2022

Students: This is a hybrid event. You are encouraged to attend in-person in STEW G-52As computing advances are making profound changes in our society, they also expose us to new security threats. While the impact of cyber attacks was often in our digital life in the past, our cyber world is increasingly intertwined with the physical world. Compromised safety-critical systems or critical infrastructures can have life and death implications. In this talk, I will highlight two research directions within my research group. First, on the system security front, I will discuss our efforts to ensure system availability on safety-critical embedded systems. Second, on the cyber-physical security front, I will present our recent work on IoT security. Finally, I will discuss our ongoing work and future directions.

Florian Kerschbaum, On Using Differential Privacy Oct 19, 2022

Differential Privacy has become a widely used tool to protect privacy in data science applications. In this talk, I will present two use cases for differential privacy: a) in collection of key-value statistics and b) as a protection against membership inference attacks. Key-value statistics are commonly used to gather information about the use of software products. Yet, the collector may be untrusted, and the data of each user should be protected. There exist a number of differentially private collection methods that perturb the data at the client's site. However, these are very inaccurate. In theory it would also be possible to collect these statistics using secure computations. However, that is too inefficient to even test. We show that a new combination of differentially privacy and secure computation achieves both high accuracy and high efficiency. In the second application, we investigate the theoretical protection of differential privacy against membership inference attacks on neural network models. There exist proofs of theoretical upper bounds that scale with the privacy parameter. We show theoretically and empirically that those bounds do not hold against existing membership inference attacks in a natural deployment. We show that when using existing data sets from different sources on the Internet (instead of the same data set as in lab experiments) and unmodified existing, even no longer state-of-the-art membership inference attacks, the bound does not hold. We provide a theoretical explanation using a model that removes an unrealistic assumption about the training that, namely that it is iid. About the speaker: Florian Kerschbaum is a professor in the David R. Cheriton School of Computer Science at the University of Waterloo (joined in 2017), a member of the CrySP group, and NSERC/RBC chair in data security (since 2019).

David C. Benson, Stop Selling Cybersecurity Short!: Cybersecurity as a Component of National Power Oct 12, 2022

Often, policy makers and cybersecurity professionals talk about cybersecurity as if cybersecurity is only important insofar as it benefits or protects other assets or values. For example, it is common to hear people argue that cybersecurity is important because of its role in economic growth, or potential damage military operations. Those arguments are not wrong, but they fail to understand national power, and consequently grossly understate cybersecurity's importance in international politics. Information is a component of national power all on its own, and cybersecurity is an important part of that component. Properly situating information as a component of national power, and cybersecurity in its appropriate place within information will better inform policy and practice. Informational considerations should hold equal weight in national policy, and not be subordinated military or economic concerns. As a component of information power, cybersecurity operates alongside other components of information power, and should cooperate with, and learn from those components of informational power. About the speaker: David Benson is currently a Professor of Security and Strategic Studies at the School of Advanced Air and Space Studies (SAASS) at Air University, Montgomery, AL. His research and instruction focuses on international relations and information, especially how the internet and information technology affects great power politics. His publications include "Why the Internet is not Increasing Terrorism," "Cyber-balancing not Cyber-War," and "Mahan and Corbett will not Inform War with China." David graduated from the University of Chicago, and held a post-doctoral appointment at Southern Methodist University. David served six years in the US Army, first as a Chinese-Mandarin linguist and then as an infantry officer.

Maggie MacAlpine, Ransomware and the Future of Cyberwarfare Oct 05, 2022

Use of Ransomware as a class of malware has exploded in recent years, causing millions in damages to organizations across the world. The damage isn't slowing down. On the contrary, ransomware as a tool is being adopted by a wide array of perpetrators. This includes nation-states, for cash, and to use the demand for cash to obfuscate activities like espionage and sabotage. Ransomware has become a powerful tool of asset seizure and extortion, being used by criminals, activists, and even sanctioned governments for multiple purposes including use as a weapon of war. The use of ransomware and its close cousin, wiperware, is only accelerating. In this talk, we will examine how the proliferation of ransomware brought us to this point, what it means for current global conflicts, and for the future of cyberwarfare.

Dipankar Dasgupta, Adaptive Multi-Factor Authentication & Cyber Identity Sep 28, 2022

Authentication is a critical part to ensure the identity of a legitimate user. During authentication, an individual's credential is validated with a specific computational technique to determine the association of the user with his/her claimed identity. In this talk, I will discuss an adaptive multi-factor authentication (A-MFA) framework which uses adaptive selection of multiple modalities at different operating environment so to make authentication strategy unpredictable to hackers. This methodology incorporates a novel approach of calculating trustworthy values of different authentication factors while the computing device being used under different environmental settings. Accordingly, a subset of authentication factors is determined (at triggering events) on the fly thereby leaving no exploitable a priori pattern or clue for adversaries. Such a methodology of adaptive authentication selection can provide legitimacy to user transactions with an added layer of access protection that is not rely on a fixed set of authentication modalities. Robustness of the system is assured by designing the framework in such a way that if any modality data get compromised, the system can still perform flawlessly using other non-compromised modalities. Scalability can also be achieved by adding new and/or improved modalities with existing set of modalities and integrating the operating/configuration parameters for the added modality.I will highlight what type of evaluation be required for such identity management software to detect possible deep fakes and other forms of faking biometrics. Other attacks on current means of identity validation may become possible. What would be what good figures of merit to be used as response variables? What are good factors over which we would need to test for next-generation identity eco-systems.References:· Advances in User Authentication. Dipankar Dasgupta,Arunava Roy, Abhijit Nag.

Cuihua (Cindy) Shen, A Fake Image is Worth a Thousand Lies Sep 07, 2022

Visual misinformation, including fake, manipulated or out-of-context images and videos, is increasingly common on the Internet and social media platforms. Because of visuals' superior impression, retention, virality and persuasiveness, visual misinformation poses a significant threat to national security, social cohesion, and public health. Yet, we know very little about how users process and judge the authenticity of visuals, and the ways in which platforms and fact-checking agencies could effectively detect and fight against visual misinformation. In this talk, I will report findings from several recent experiments that reveal the characteristics of users most susceptible to visual misinformation, and a few effective technical and social interventions to counter visual misinformation. About the speaker: Cuihua (Cindy) Shen is a professor of communication at UC Davis and the co-director of the Computational Communication Research lab.

Chris Jenkins, Moving Target Defense for Space Systems Aug 31, 2022

Students: This is a hybrid event. You are encouraged to attend in person in STEW 050B (G52)Space systems provide many critical functions to the military, federal agencies, and infrastructure networks. Space Policy Directive-5 Cybersecurity Principles for Space Systems describes both the cyber threat to space systems and the need for these systems to be secure and resilient against cyber-attacks. Most cyber defenses for space systems rely on the ability to detect the adversary. Reliance on detection is a risky proposition, given that anomaly and threat detection remains an open research challenge for both terrestrial and space systems. Furthermore, cyber defenses for space systems must be implemented in size, weight, and power (SWAP)-constrained, real-time operating environments that cannot tolerate increased latency and other common detrimental side-effects of cyber defenses. To overcome these challenges, we have been researching the use to moving target defenses (MTD) to protect space systems against cyber-attacks. MTDs create dynamic, uncertain environments on space systems and can be used to defeat cyber threats against these systems. Furthermore, MTDs do not require detection of an adversary to mitigate the effects of an attack. Our multi-stage-stage research approach is as follows:Development of a generalized MTD algorithm: though conceptually simple, implementation of MTD can be complex. The first research phase focused on the development of a generalized MTD algorithm that implements randomization schemes with limited impact to nominal operations and failsafe commands to re-sync devices, if needed. Application of the MTD algorithms to an exemplar: we demonstrated the MTD algorithm on real MIL-STD-1553 hardware using 4 MTD commandsFunctional experiments: we evaluated the reliability of the MTD algorithms and whether the use of MTD added unacceptable operational overhead.Cyber resilience experimentation and validation: we exposed the hardware and MTD to cyber-attacks to determine the effectiveness of the MTD algorithms at thwarting attacks and thereby increasing resilience to the attacks.Machine learning experiments: we used machine learning models to analyze whether the MTD algorithm introduced vulnerabilities and if the machine learning models could "crack" the MTD algorithm and predict randomization sequences. The MTD performed well in each of the experiments. Most notably, the cyber resilience experiments showed a 97% reduction in adversarial knowledge. Furthermore, small changes in the MTD algorithm substantially decreased the ability of the machine learning model to decipher randomization sequences.

Paul Rosenzweig, Crowd Forecasting to Enhance Cybersecurity Apr 13, 2022

For at least two decades, the U.S. intelligence community and special projects agencies have been exploring the potential of prediction markets and crowd-forecasting platforms to better forecast geopolitical and technical trends. Similarly, a number of prominent corporations, including Google, Ford, Yahoo, Hewlett-Packard, and Eli Lilly, have likewise turned to these tools to predict everything from which product lines will be most profitable to whether a deadline is likely to be met. Yet despite this seeming opportunity, there remains a significant gap: almost nobody has deployed the tools for crowd-forecasting to cybersecurity problems. We propose to change that paradigm. We believe that a cybersecurity-focused forecasting market can create useful value-added information for decision-makers. To test this hypothesis we have begun a small beta test applying the principles of crowd-forecasting directly to a set of cybersecurity questions.This talk will provide background on the use of crowd-forecasting for policy and discuss some interim results of the ongoing beta test.

Richard Clarke, Now That We're in a Hybrid War… Mar 30, 2022

The war Russia has waged on Ukraine has seemed largely kinetic, but the most effective weapons weilded thus far have been consumer technologies. Putin has pursued a hybrid warfare strategy, yet the Ukrainians have fought his mendacious claims with the realities of conflict captured by mobile devices and social media. Bogged down by guerilla fighting in Ukrainian cities, Putin will view offensive cyber action and aggressive information warfare as increasingly appealing options. Richard Clarke, former U.S. National Coordinator for Security, Infrastructure Protection and Counterterrorism, and the nation's first "Cyber Czar," will give us an inside look at what the world has learned about the spillover of warfare in an era of advanced cyber threats.In his latest book, The Fifth Domain: Defending Our Country, Our Companies, and Ourselves in the Age of Cyber Threats, Clarke delves deep into the political and economic calculations of cyber conflict. He also provides concrete steps that can be taken to achieve cyber resilience, during peacetime and amidst international conflict, including building more resistant systems and raising the costs for escalations in cyberspace. About the speaker: Richard A. Clarke served for thirty years in national security policy roles in the US Government, first in the Pentagon, then the State Department, and finally for an unprecedented decade of continuous service for three Presidents in the White House.In the White House National Security Council for President Bush (41), Clinton, and Bush (43) he served as Special Assistant to the President for Global Affairs, National Coordinator for Security and Counter-terrorism ("Terrorism Czar'), and Special Advisor for Cyberspace (the first "Cyber Czar").

Dr. Chris C. Demchak, Robust Collective Cyber Power across Consolidated Democracies Feb 09, 2022

The complexities of and losses from a shoddily created cyberspace substrate continue to hollow the economies and national power of consolidated democracies. As China rises as a strategically focused and digitally aggressive authoritarian giant, it is critical that democratic leaders both understand the reality they face and how an institutional alternative may be created to avoid being weak cyber powers in the future. This presentation offers two models: the ‘Cybered Conflict' model to lay the foundation explanation for the weakness in national cyber power of democracies, and the ‘Cyber Operational Resilience Alliance (CORA) model to explain how this existentially threatening trend may be turned around through allied action to jointly ensure cyber resilience. Finally the talk will outline very briefly how the CORA model may be used analytically to improve the cyber resilience alliance potential of national cyber strategies, and to identify organizations capable of contributing to more robust collective cyber defenses across sectors and allied democratic nations. About the speaker: With engineering, economics, and comparative complex organization theory/political science degrees, Dr. Chris C. Demchak is the RDML Grace M. Hopper Professor of Cyber Security and a member of the Cyber and Innovation Policy Institute, U.S. Naval War College.

Alyssa Miller, Threat Modeling in the World of DevOps Feb 02, 2022

Threat modeling is an extremely valuable tool in the secure software development pipeline. Some studies suggest it has greater impact on security posture than other more widely practiced security activities. There are many different frameworks, models, and methodologies that have been developed in an attempt to make threat modeling easier. Yet, despite these efforts, popular approaches to threat modeling are often still considered too cumbersome, structured, or time consuming to fit with modern DevOps and CI/CD development.In 2020, a group of 15 security professional released the Threat Modeling Manifesto to formalize decades of combined experience into a declared vision of what threat modeling truly is and what makes it important. Learn from one of these authors about how to break with the complex models and return to the values and principles of what threat modeling should be. Discover how this often-over-looked activity can be implemented in development pipelines and make them more efficient while improving overall security of software.

Dr. David Mussington, Critical Infrastructure Resilience Hinges on Cyber-Physical Convergence Jan 26, 2022

Cyber-physical systems are delivering an increasing portion of the infrastructure services at the heart of our economy and national security, and you don't have to look far for examples of technology-enabled, industrial control, and the internet-of-things in the core operations of healthcare, food and agriculture, energy, transportation, or manufacturing. Further, one has only to look at the contemporary examples of our systems under stress, such as the JBS and Colonial Pipeline cyber attacks, to understand the fragile risk ecosystem confronting infrastructure owners and operators of cyber-physical systems.In fact, the title of this talk is purposely a catch-22, meaning that just as infrastructure resilience is inherently dependent on safe and secure cyber-physical systems, so too is the collective work to see cyber and physical security achieve resilience.

Kacper Gradon, Future Trends in Cyber Crime and Hybrid Warfare Dec 01, 2021

"Do Criminals Dream of Electric Sheep?" Such issue is no longer a domain of futurologists and science-fiction writers, but a serious question asked by the EUROPOL alarmed by how emerging Information Technologies shape the future of crime and law-enforcement. Apart from its obviously positive effects, the technology also impacts and affects the way criminal offenders, terrorists and rogue governments operate at the stages of know-how gathering, planning, preparation and execution of their attacks. The progress in the development of IT and its accessibility is so unprecedentedly high, that– in order not to lag behind – the law-enforcement and intelligence communities need to research and analyze the further and potential advances (and design the potential preventive measures) promptly. The presentation addresses the problem of a lack of forecasting/analytical approach to the study of an impact of emerging and disruptive technologies on the criminal, terrorist and information warfare landscape. The author aims to deliver the most up-to-date analysis of the threats to come, together with a set of plausible solutions on how to deter and mitigate the risk. The presentation will characterize the dangers posed by the potential abuse of Information Technologies by the criminal/terrorist/state actors. The author will deliver an analysis articulating the key factors implicated in events related to the technology abuse, across all stages of the event. The presentation will cover such areas as e.g.: 1) abuse of the open source information for planning, preparation & execution of the attack; 2) hazards associated with the abuse of wearable devices; 3) use of mobile technologies to profile, select and groom potential activists or extremists or to enable human trafficking and sexual exploitation of children; 4) attacks on Internet of Things networks for targeting specific individual/entity or to create mass-level disruption incl. attacks on critical national infrastructure; 5)hijacking of autonomous vehicles; 6) use of drones (aerial, ground operating, hydroid) for surveillance, as weapons, for drugs delivery, as burglary bots, as tools to disrupt civil aviation or military systems; 7) attacks on IP-enabled medical devices; 8) the use of (semi)autonomous robots; 9) the use of the Artificial Intelligence, machine-learning, deep-learning and reinforcement learning techniques for various criminal/terrorist objectives; 10) abuse of blockchain technologies and crypto-currencies (financing of terrorism, money laundering, bribery, financing of illegal activities, extortion/ransomware); 11)abuse of 3D printing technologies; 12) risk associated with Quantum Computing and 5G telecom networks (increased capabilities of criminal/terrorist/cyber-warfare operations). A special focus will be put on Information Warfare (hybrid and asymmetric threats), where disinformation, misinformation and propaganda are used by nation states in a general scheme of malign foreign influence to disrupt the situation abroad.

Jeremiah Blocki, Password Strength Signaling: A Counter-Intuitive Defense Against Password Cracking Oct 27, 2021

We introduce password strength information signaling as a novel, yet counter-intuitive, defense mechanism against password cracking attacks. Recent breaches have exposed billions of user passwords to the dangerous threat of offline password cracking attacks. An offline attacker can quickly check millions (or sometimes billions/trillions) of password guesses by comparing their hash value with the stolen hash from a breached authentication server. The attacker is limited only by the resources he is willing to invest. Our key idea is to have the authentication server store a (noisy) signal about the strength of each user password for an offline attacker to find. Surprisingly, we show that the noise distribution for the signal can often be tuned so that a rational (profit-maximizing) attacker will crack fewer passwords. The signaling scheme exploits the fact that password cracking is not a zero-sum game i.e., the attacker's profit is given by the value of the cracked passwords minus the total guessing cost. Thus, a well-defined signaling strategy will encourage the attacker to reduce his guessing costs by cracking fewer passwords. We use an evolutionary algorithm to compute the optimal signaling scheme for the defender. As a proof-of-concept, we evaluate our mechanism on several password datasets and show that it can reduce the total number of cracked passwords by up to 12% (resp. 5%) of all users in defending against offline (resp. online) attacks.

Paula deWitte, The Need for Legal Education within a Cybersecurity Curriculum Sep 22, 2021

Anecdotally, most cybersecurity curricula is based on the technical aspects of protecting, defending, and responding to cyber attacks. While these courses establish a solid foundation in the technical aspects of cybersecurity, what is often missing is establishing a foundation in cybersecurity law. Every individual who puts their hands on a keyboard operates within an uncertain ethical and legal framework. What we do not need is the type of education to produce more lawyers, but rather the type of education to produce more legal-savvy technical workers. Today's tech workers are exposed to more personal information as well as intellectual property – both targets in cyber attacks. They are expected to protect critical infrastructure and design with security "built in." Yet, we do a poor job teaching the legal requirements as well as limitations imposed by law on building in privacy protections.For the past four years, the speaker has taught Cybersecurity Law & Policy to several hundred computer science and engineering students as well as those from business, architecture, technology management, and government policy. I began this course by conducting a data analytics exercise on the NIST NICE Framework to determine what work roles require legal training. The results were quite surprising as even very technical roles such as Threat Analysis and System Architecture require knowledge of laws, policies,and ethics as they relate to cybersecurity and privacy as well as knowledge of investigations. The feedback from graduating students who take on cybersecurity roles is that they are uniquely qualified to understand the necessity of compliance within their respective roles. This presentation will discuss the basis for legal education as well as a roadmap for how to incorporate such legal education within a cybersecurity curriculum to build the workforce necessary for the current cybersecurity environment. About the speaker: Paula S. deWitte, J.D., Ph.D,. P.E., is an Associate Professor of Practice in the Computer Science and Engineering Department at Texas A&M University, College Station and the Maritime Business Administration Department at Texas A&M University, Galveston where she is building the maritime cybersecurity program.

Nasir Memon, AI, Computational Imaging and the Battle for Media Integrity Jul 28, 2021

Rapid progress in machine learning, computer vision and graphics leads to successive democratization of media manipulation capabilities. While convincing photo and video manipulation used to require substantial time and skill, modern editors bring (semi-) automated tools that can be used by everyone. Some of the most recent examples include manipulation of human faces, e.g., by their replacement or semantic manipulation (expression, age, etc.). At the same time, dissemination of fake news and misinformation campaigns are picking up speed which challenges trust in the society. Our media distribution platforms lack content integrity features as they were designed and optimized for the quality of (human) experience with strict bandwidth / storage constraints. Such an approach fails to recognize an increasing role of automated analysis by machine learning models, e.g, strong lossy compression applied to media assets removes imperceptible statistical traces indicative of content manipulation and is often referred to as media "laundering" process. In this talk, we explore end-to-end optimization of photo acquisition and distribution pipelines for media authentication. We show that feedback from forensic analysis can be used to optimize upstream components like the camera ISP or lossy compression codecs to support media authentication on the receiving end. Modern machine learning tools allow us to discover new approaches to the problem with surprising connections to other fields like information hiding, computational photography, lossy compression and machine learning security. To enable this line of work, we are currently developing a Tensorflow-based open source toolbox for modeling and optimization of various imaging applications (https://github.com/pkorus/neural-imaging).

Winn Schwartau, Security is Probabilistic, Not Deterministic: Get Over It Jul 07, 2021

Since the inception of computer/data/cyber/network securitysome fifty years ago, one recurring question has beset our industry: "How do wesecure it?" By its very nature, that question has propagated as a harmful meme,by implying that a binary deterministic answer is available, or even possible. This talk examines security through a non-deterministiclens, applying probabilistic and analogue functions to discover new approachesto defending anthro-cyber-kinetic systems. About the speaker: Winn has lived Cyber Security since 1983, and now says, "I think, maybe, I'm just starting to understand it." His predictions about the internet & security have been scarily spot on. He coined the term "Electronic Pearl Harbor" while testifying before Congress in 1991 and showed the world how and why massive identify theft, cyber-espionage, nation-state hacking and cyber-terrorism would be an integral part of our future. He was named the "Civilian Architect of Information Warfare," by Admiral Tyrrell of the British MoD. His new book, "Analogue Network Security" is a mathematical, time-based and probabilistic approach to justifiable security. His goal is to provide a first set of tools and methods to "fix security and the internet", including fake news, spam, phishing, DDoS and more. It will twist your mind.

Neil Gong, Secure Federated Learning Jun 09, 2021

Federated learning is an emerging machine learning paradigm to enable many clients (e.g., smartphones, IoT devices, and edge devices) to collaboratively learn a model, with help of a server, without sharing their raw local data. Due to its communication efficiency and potential promise of protecting private or proprietary user data, and in light of emerging privacy regulations such as GDPR, federated learning has become a central playground for innovation. However, due to its distributed nature, federated learning is vulnerable to malicious clients. In this talk, we will discuss local model poisoning attacks to federated learning, in which malicious clients send carefully crafted local models or their updates to the server to corrupt the global model. Moreover, we will discuss our work on building federated learning methods that are secure against a bounded number of malicious clients.

Gary McGraw, Security Engineering for Machine Learning May 26, 2021

Machine Learning appears to have made impressive progress on many tasks including image classification, machine translation, autonomous vehicle control, playing complex games including chess, Go, and Atari video games, and more. This has led to much breathless popular press coverage of Artificial Intelligence, and has elevated deep learning to an almost magical status in the eyes of the public. ML, especially of the deep learning sort, is not magic, however. ML has become so popular that its application, though often poorly understood and partially motivated by hype, is exploding. In my view, this is not necessarily a good thing. I am concerned with the systematic risk invoked by adopting ML in a haphazard fashion. Our research at the Berryville Institute of Machine Learning (BIIML) is focused on understanding and categorizing security engineering risks introduced by ML at the design level. Though the idea of addressing security risk in ML is not a new one, most previous work has focused on either particular attacks against running ML systems (a kind of dynamic analysis) or on operational security issues surrounding ML. This talk focuses on the results of an architectural risk analysis (sometimes called a threat model) of ML systems in general. A list of the top five (of 78 known) ML security risks will be presented. About the speaker: Gary McGraw is co-founder of the Berryville Institute of Machine Learning. He is a globally recognized authority on software security and the author of eight best selling books on this topic. His titles include Software Security, Exploiting Software, Building Secure Software, Java Security, Exploiting Online Games, and 6 other books; and he is editor of the Addison-Wesley Software Security series. Dr. McGraw has also written over 100 peer-reviewed scientific publications. Gary serves on the Advisory Boards of Code DX, Maxmyinterest, Runsafe Security, and Secure Code Warrior. He has also served as a Board member of Cigital and Codiscope (acquired by Synopsys) and as Advisor to Black Duck (acquired by Synopsys), Dasient (acquired by Twitter), Fortify Software (acquired by HP), and Invotas (acquired by FireEye).

His dual PhD is in Cognitive Science and Computer Science from Indiana University where he serves on the Dean's Advisory Council for the Luddy School of Informatics, Computing, and Engineering.

Steven Furnell, Cybersecurity Skills – Easy to say, harder to recognise? Apr 28, 2021

There is no doubt that cybersecurity has risen up the agenda in terms of visibility and importance. Everybody wants it. But do they really know what they want? What does cybersecurity include, and to what extent do qualifications and certifications that claim to cover it actually do so? This talk examines what cybersecurity means in terms of the contributing topics, and in particular how these topics can end up looking substantially different depending upon what source we use as our reference point. The discussion then proceeds to examine how this has knock-on impacts in terms of the qualifications and certifications that may be held by our current and future workforce. All are labelled as ‘cybersecurity', but to what extent are they covering it, and how can those that need support tell the difference?

Yimin Chen, Delving into differential privacy and anomaly detection: a meta-learning perspective Apr 14, 2021

In this talk, we explore security and privacy related to meta-learning, a learning paradigm aiming to learn 'cross-task' knowledge instead of 'single-task' knowledge. For privacy perspective, we conjecture that meta-learning plays an important role in future federated learning and look into federated meta-learning systems with differential privacy design for task privacy protection. For security perspective, we explore anomaly detection for machine learning models. Particularly, we explore poisoning attacks on machine learning models in which poisoning training samples are the anomaly. Inspired from that poisoning samples degrade trained models through overfitting, we exploit meta-training to counteract overfitting, thus enhancing model robustness. About the speaker: Yimin Chen is now a postdoctoral researcher in Computer Science department in Virginia Tech. Currently his research mainly focuses on differential privacy, anomaly detection, adversarial example, and private learning. Before he worked on security and privacy of mobile computing systems for his PhD study.

Tawei (David) Wang, The Invisible Risks: An Empirical Analysis on Data Sharing Activities and Systemic Risk among the Data Brokers Apr 07, 2021

Data brokers are the major players in the market of collecting, selling, and sharing online user information. Although their practices have raised tremendous privacy concerns, their data collection and sharing activities are still under the veil. The growth of adverse cybersecurity incidents toward the data brokers has led the regulators, including California and Vermont, to require the data brokers to register and disclose their activities. This paper analyzes the leaked information on the dark web to analyze the data sharing and collection activities among the data brokers. In specific, we cluster the data brokers based on their data collection activities given by their product description to quantify the activity proximity. Next, we empirically examine how activity proximity leads to co-occurrence on the leaked information in the dark web. We further discuss the deterrence effect of the data broker registration on information leakage. Our study contributes to cybersecurity assurance and risk assessment literature by unveiling the shadowy data-collecting and data-sharing market. About the speaker: Tawei (David) Wang is currently an Associate Professor and Driehaus Fellow at DePaul University. He received his Ph.D. from Krannert Graduate School of Management, Purdue University in 2009. His research interests are information security management and IT management.

Frederick Scholl, Cybercrime: A Proposed Solution Mar 31, 2021

Modern cybercrimes are responsible for $400B dollars of losses on an annual basis. Headlines appear regularly announcing major breaches. Yet few people and businesses understand what happened in such incidents and how to avoid being a victim themselves. The security industry does provide analyses of breach statistics, but effective preventative measures can be lost in the numbers. Virtually all breaches result from technology failure combined with people failure.This presentation will look at actual recent cybercrimes in order to document what happened and what could have prevented that incident. Who carried out the breach? What did they do? What was taken? How could it have been stopped? What was the story behind the breach? Attack types include ransomware, business email compromise, intellectual property theft and breach of Personally Identifiable Information. By being more familiar with current successful threats and breaches you will:· Be able to avoid high risk activities, if possible· Be able to be better prepared to stop such an attack against you or your organization· Be able to optimize security spending and resources for actual attack patternsThis presentation is designed for both security professionals and business professionals who want to better secure their assets and processes against the increasing number of cyber criminals. About the speaker: Frederick W.Scholl is an accomplished global information security risk manager with a unique record of accomplishment in business and technology.

Randall Brooks, Cyber Supply Chain Risk Management (SCRM) and its impact on information and Operational Technology (IT/OT) Mar 03, 2021

In a growing interdependent market place,it is nearly impossible to develop every part or component in house. Electronics are nearly entirely manufactured offshore. Concerns have risen about the trust worthiness of electronics that may contain extra or potentially malicious functionality. Traditional supply chain risk management only deals with the suppliers ability to deliver a product on time and within budget. Cyber aspects focus on the trustworthiness of the product that was delivered. Those vendor that they themselves are procuring products, such as test systems,subtractive or additive manufacturing, are now concerned that the products they are producing are affected by Cyber Supply Chain Risk Management (C-SCRM). About the speaker: Mr. Randall Brooks is a Principal Engineering Fellow for Raytheon Technologies (NYSE: RTX). He is the Director of the Raytheon Cyber Center of Excellence.

Cory Doctorow, Technology, Self-Determination, and the Future of the Future Feb 17, 2021

Self-determination is the key to human thriving; it's also the enemy of both dictatorships and monopolies. It's no coincidence that commercial imperatives of tech monopolies create the infrastructure for political oppression. The public-private-partnership from hell looks like this: companies install surveillance and other system of control to extract higher rents from their customers and ward off competitors. Then states seize that surveillance and control apparatus to gain and consolidate power.That's the bad news. The good news is that it means that those of us fighting dictatorships have natural allegiances with those fighting monopolies -- and vice versa.

Scott Shackelford, The Internet of Things: What Everyone Needs to Know Jan 27, 2021

The Internet of Things (IoT) is the notion that nearly everything we use, from gym shorts to streetlights, will soon be connected to the Internet. Industry and financial analysts have predicted that the number of Internet-enabled devices will increase from 11 billion to upwards of 25 billion in coming years. Regardless of the number, the end result looks to be a mind-boggling explosion in Internet connected stuff. Yet, there has been relatively little attention paid to how we should go about regulating smart devices, and still less about how cybersecurity should be enhanced. Similarly, now that everything from refrigerators to stock exchanges can be connected to a ubiquitous Internet, how can we better safeguard privacy across networks and borders? This talk will explore these issues by pulling from the recently published book, ‘The Internet of Things: What Everyone Needs to Know.' Our discussion will also be couched by the findings of a recent report for the Indiana Executive Council on Cybersecurity entitled, ‘State of Hoosier Cybersecurity 2020.' About the speaker: Professor Scott J. Shackelford serves on the faculty of Indiana University where he is Cybersecurity Program Chair along with being the Executive Director of the Ostrom Workshop.

Adwait Nadkarni, Building Practical Security Systems for the Post-App Smart Home Jan 20, 2021

Modern end-user computing platforms such as smartphones (e.g., Android and iOS)and smart home systems (e.g., SmartThings and NEST) provide programmable interfaces for third-party integration, enabling expressive and popular functionality that is often manifested in applications, or apps. Thus, for the last decade, designing security systems to analyze apps for vulnerabilities or unwanted behavior has been a major focus within the security community. This approach has continued well into the smart home, with researchers developing systems inspired by lessons from Android security to inspect IoT apps developed for popular platforms such as SmartThings. However, emerging characteristics of smart home ecosystems indicate that IoTapps may not represent automation in real homes, and may even be unavailable in the near future. That is, while API misuse by third-party developers is an important problem, the approach of analyzing/instrumenting IoT apps may not offer an effective or sustainable solution.In this talk, I will describe the challenges for research in the backdrop of the unsuitability of IoTapps for practical security analysis, and motivate three alternate research directions. First, I will describe the need to develop an alternative artifact for security analysis that is representative of automation usage in the wild. To this end, I will introduce Helion, a system that uses statistical language modeling to generate natural home automation scenarios, i.e., realistic event sequences that are closely aligned with the real home automation usage in end-user homes,which can be used for security or safety analysis. Second, I will illustrate the need to improve the security of mobile companion apps, which often form the weakest link in smart home deployments, and the important position of security analysis/compliance tools in ensuring the development of secure companion apps. To this end, I will present the mSE framework, which automatically and rigorously evaluates static program analysis-based security systems using mutation testing. Our work on mSE (and its successor, MASC) culminated in the discovery of critical security flaws in popular tools such as FlowDroid, CryptoGuard, Argus, and Coverity that affect the reliability and soundness of their analysis. Finally, I will conclude the talk by describing our current efforts to build system-level defenses into IoT platforms that are agnostic to IoTapps, i.e., independent of their visibility or mutability, thereby potentially providing a lasting solution to API misuse by third-party developers. About the speaker: Adwait Nadkarni is an Assistant Professor in the Department of Computer Science, and director of the Secure Platforms Lab (SPL) at William & Mary. Prof. Nadkarni's primary research domain is security and privacy, with a focus on emerging platforms, and the areas of operating systems and software security.

Lorrie Cranor, Security and Privacy for Humans Dec 09, 2020

Traditionally, security and privacy research focused mostly on technical mechanisms and was based on the naive assumptions that Alice and Bob were capable, attentive, and willing to jump through any number of hoops to communicate securely. However, about 20 years ago that started to change when a seminal paper asked "Why Johnny Can't Encrypt" and called for usability evaluations and usable design strategies for security. Today a substantial body of interdisciplinary literature exists on usability evaluations and design strategies for both security and privacy. Nonetheless, it is still difficult for most people to encrypt their email, manage their passwords, and configure their social network privacy settings. In this talk I will highlight some of the lessons learned from the past 20 years of usable privacy and security research, and explore where the field might be headed. About the speaker: Lorrie Faith Cranor is the Director and Bosch Distinguished Professor in Security and Privacy Technologies of CyLab and the FORE Systems Professor of Computer Science and of Engineering and Public Policy at Carnegie Mellon University.

Kimberly Ferguson-Walter, Maximizing Cyber Deception to Improve Security: An Empirical Analysis Dec 02, 2020

The threat of cyber attacks is a growing concern across the world, leading to an increasing need for sophisticated cyber defense techniques that leverage the defender's "home field advantage". We designed the Tularosa Study to understand how defensive deception, both cyber and psychological, affects cyber attackers. Over 130 professional red teamers participated in a network penetration test over two days in which both the presence of and explicit mention of deceptive defensive techniques were controlled. To our knowledge, this represents the largest study of its kind ever conducted on a skilled red team population. The design was conducted with a battery of questionnaires (e.g., experience, personality, etc.) and cognitive tasks (e.g., fluid intelligence, working memory, etc.), allowing for the characterization of a "typical" red teamer, as well as physiological measures (e.g., galvanic skin response, heart rate, etc.) to be correlated with the cyber events. Preliminary results support a new finding that the combination of the presence of deception and the true information that deception is present has the greatest effect on cyber attackers, when compared to a control condition in which no deception was used.Special PanelImmediately following Dr. Ferguson-Walter's seminar, join CERIAS for a unique opportunity to hear six professionals from NSA -- including two Purdue alumni -- who will share their careers and experiences as cybersecurity researchers and practitioners.

Sivaram Ramanathan, Improving the Accuracy of Blocklists by Aggregation and Address Reuse Detection Nov 18, 2020

IP address blocklists are a useful source of information about repeat attackers. Such information can be used to prioritize which traffic to divert for deeper inspection (e.g., repeat offender traffic), or which traffic to serve first (e.g., traffic from sources that are not blocklisted). But blocklists also suffer from overspecialization -- each list is geared towards a specific purpose -- and they may be inaccurate due to misclassification or stale information. We propose BLAG, a system that evaluates and aggregates multiple blocklists feeds, producing a more useful, accurate and timely master blocklist, tailored to the specific customer network. BLAG uses a sample of the legitimate sources of the customer network's inbound traffic to evaluate the accuracy of each blocklist over regions of address space. It then leverages recommendation systems to select the most accurate information to aggregate into its master blocklist. Finally, BLAG identifies portions of the master blocklist that can be expanded into larger address regions (e.g. /24 prefixes) to uncover more malicious addresses with minimum collateral damage. Our evaluation of blocklists of various attack types and three ground-truth datasets shows that BLAG achieves high specificity up to 99%, improves recall by up to 114 times compared to competing approaches, and detects attacks up to 13.7 days faster, which makes it a promising approach for blocklist generation. Although performance of blocklists can be improved, they need to be used carefully. Blocklists can potentially lead to unjust blocking to legitimate users due to IP address reuse, where more users could be blocked than intended. IP addresses can be reused either at the same time (Network Address Translation) or over time (dynamic addressing). We present two new techniques to identify reused addresses. We built a crawler using the BitTorrent Distributed Hash Table to detect NATed addresses and use the RIPE Atlas measurement logs to detect dynamically allocated address spaces. We then analyze 151 publicly available IPv4 blocklists to show the implications of reused addresses and find that 53--60% of blocklists contain reused addresses having about 30.6K--45.1K listings of reused addresses. We also find that reused addresses can potentially affect as many as 78 legitimate users for as many as 44 days. About the speaker: Sivaram is a fifth-year Ph.D. student at the University of Southern California. His research focuses on developing systems to improve internet security and providing better measurements in the network.

Yoon Auh, NUTS: eNcrypted Userdata Transit & Storage; Viewing Data as an Endpoint™ (DaaE) using Structured Cryptography Oct 28, 2020

Can objects be truly secured independently without resorting to a massive central reference monitor? It's a great question and we will discuss a solution to it called NUTS. During this talk, we'll take data structures, message protocols and applied cryptography and toss them into the cauldron of reality, sprinkle in some DNA and data management to brew up some Security at the Data Perimeter towards crafting Data as the Endpoint. It sounds like a bad witch's brew of epic proportions but once we cast the spell, you will see the integration of many CS/CISSP concepts you've learned over the years and new ways to use it. Our goal is to make sure that the private individual has the best applied cryptographic technologies at their disposal for free in an unobtrusive way. By the way, a nut is the only secure data structure we know of that can help mitigate insider threats in a purely cryptographic way independent of reference monitors. We'll also show you how the NUTS Ecosystem can provide Alice with a ransom-ware resistant ‘hot' system at home using just 2 computers. About the speaker: Yoon Auh, CISSP, is the founder and CEO of NUTS Technologies® Inc., a midwestern cybersecurity startup. He holds multiple US patents around structured security and structured cryptography. His firm is breaking new grounds in applying structured security and cryptography at the data layer. He graduated from Columbia College in NYC with a BA in Physics and a BS in Engineering Mechanics from Columbia School of Engineering. Yoon's prior career was in finance and technology culminating to a successful career as Head Trader for several world class financial firms. A little NUTS history; Tired of poor personal data protection tools and even worse data management methods for the average Joe, Yoon created the eNcrypted Userdata Transit & Storage (NUTS) ecosystem which relies on viewing Data as the Endpoint™. To this end, a secure cryptographic data structure was created called a nut which is a complex structured cryptographic data structure featuring built-in multi-layered, multi-model pure cryptographic access controls requiring no reference monitors (if you understood this sentence, you are in for a real treat) - essentially, a nut allows the security perimeter to be brought down to the data layer so that it can travel with it.

Jeff Man, Why Attack When You Can Defend Oct 21, 2020

MITRE ATT&CK® seems to be the"next big thing". Every time I hear about it I can't help but wonder, "how doyou prevent all these attacks in the first place? Shouldn't that be the endgame?" To that end, I set out to map all the recommended "Mitigations" for allthe "Techniques" detailed in ATT&CK to see how many are already addressedby what is required in the Payment Card Industry Data Security Standard (PCIDSS). My hypothesis was all of them. The results were interesting and a little surprising, and I'm still trying to figure out how to best use the results and subsequently ATT&CK itself. I will present my findings in the briefing andhopefully generate a discussion about what to do with the results.

Courtney Falk, The Pod People Campaign: Driving User Traffic via Social Networks Oct 14, 2020

Users of social networks are having their accounts subverted. Threat actors are gaining unauthorized access to large numbers of accounts and inserting links to suspicious websites. Shared command-and-control infrastructure is used across 70+ different social networks, suggesting a coordinated campaign to drive user traffic. The actors behind this campaign, and the end goal for driving user traffic, remains uncertain. The campaign remains active with changing indicators. The fact that this campaign spans so many different social networks makes determining the scope of the overall problem difficult. Using Goodreads as an example, we detail how the attack is constructed. About the speaker: Dr. Courtney Falk is an information security professional with over fifteen years of experience in the government, academic, and public sectors. He earned his doctorate of philosophy from Purdue University in the interdisciplinary information security program.

Roger Schell, Dramatically Reducing Attack Surface Using Integrity MAC Security Kernel Sep 02, 2020

We face an existential threat of permanent damage to critical physical components in our national infrastructure as a result of their poor resilience against cybersecurity attack. A Programmable Logic Controller (PLC) commonly provides the control system for such components, e.g., bulk power generators. Our proof-of-concept implementation dramatically mitigates threats to such cyber-physical systems (CPS) by specifically leveraging what NIST 800-160 calls "highly assured, kernel-based operating systems in Programmable Logic Controllers".We dramatically reduce the attack surface visible to potential attackers to be ~1% of the total compared to competing approaches. Our demonstration refactors the common CPS architectural approach to data and cooperating processes into hierarchically ordered security domains using the widely available OpenPLC project code base. The GEMSOS security kernel verifiably enforces traditional integrity mandatory access control (MAC) policy on all cross-domain flows. GEMSOS is designed for wide-spread delivery as a Reusable Trusted Device, providing the reference monitor for secure single-board, multi-board, and System-on-a-Chip systems.Only a processing component in the highest integrity domain can directly send/receive control signals, enforcing "safe region" operating constraints to prevent physical damage. This very small attack surface protects the critical physical components, making the overall CPS resilient to skilled adversaries' attacks, even though much larger lower integrity software running in other domains on the same Trusted Device hardware and network infrastructure may be thoroughly compromised. We make available our restructured OpenPLC source to encourage control system manufacturers to deliver verifiable PLC products to, as NIST puts it, "achieve a high degree of system integrity and availability" for control systems. UC Davis is using our demonstration on GEMSOS in their Computer Security Lab, today. About the speaker: Roger R. Schell is internationally recognized for originating several key modern security design and evaluation techniques, and was awarded patents in cryptography, authentication and trusted workstation. His experience includes 20 years in US federal program management (computers), 30 years as a computer industry security product vendor, and 5 years as a graduate cybersecurity engineering faculty member.He is President and a founder of Aesec Corporation, a start-up providing a commercial verifiably secure operating system.

Elena Peterson, Flexible and Adaptive Malware Identification Using Techniques from Biology Aug 19, 2020

Cyber security data in many ways mimics the behavior of organic systems. Individuals or groups compete for limited resources using a variety of strategies, the most effective of which are re-used and refined in later ‘generations'. Traditionally this behavior has made detection of malware very difficult because 1) recognition systems are often built on exact matching to a pattern that can only be ‘learned' after a malicious entity reveals itself and 2) the enormous volume and variation in benign code is an overwhelming source of previously unseen entities that often confound detectors. In addition, the enormous volume of malware artifacts is overwhelming anyone trying to categorize and characterize new additions to the many malware repositories as so much of the processing is done by hand.To turn the tables of complexity on the attackers, we have developed a method for mapping the sequence of behaviors that make up a malicious artifact to strings of text and analyze these strings using modified bioinformatics algorithms. Bioinformatics algorithms optimize the alignment between text strings even in the presence of mismatches, insertions or deletions and do not require an a priori definition of the patterns one is seeking. Nor do they require any type of exact matching. This allows the data itself to suggest meaningful patterns that are conserved between binaries. These patterns can be used to identify zero-day malware and can help to automate the curation and characterization of large quantities of suspected malware. I will talk about our MLSTONES capabilities as an innovative and effective way of detecting and characterizing most types of malware artifacts. I'll also discuss how these capabilities can be used on other types of cyber security data. About the speaker: Elena Peterson --Ms Peterson joined PNNL in 1990 after getting her BS in Computer and Information Sciences from the University of Oregon.

Shimon Modi, Value of Cyber Threat Intelligence in Modern Security Operations Aug 12, 2020

The last 5 years have seen a marked shift inhow companies view cyber threat intelligence (CTI) as a building block of theirsecurity strategy, but there still is a lot of confusion about how to build aprogram that provides utility. At its core CTI aims to provide informationabout motivations, methods and characteristics of attackers. In today's rapidlyevolving threat landscape having timely access to CTI can be of significantvalue to security analysts. By looking beyond your own four walls organizationscan take faster mitigation action and also reduce their attack surface. AddingCTI to enterprise security programs can be an effective strategy to go from areactive to a proactive response. But the value of CTI is constrained by theability of enterprise security operations to contextualize, manage and actionupon it. This presentation will cover some fundamental CTI concepts, real worldchallenges in operationalizing it, and some easy ways to try it out foryourself. Takeaways for the audience:1. Overview of CTI concepts, frameworks,standards, and how they fit in the enterprise security model.2. Clearer understanding of CTI data modelsand how they integrate with detection, protection and incident responseprocesses. 3. Practical ways to accelerate securityoperations and heighten defenses using CTI.

Sami Saydjari, A Principled Approach to Cybersecurity Engineering Jun 17, 2020

Cyberattacks are increasing in frequency, severity, and sophistication. Target systems are becoming increasingly complex with a multitude of subtle dependencies. Designs and implementations continue to exhibit flaws that could be avoided with well-known computer-science and engineering techniques. Cybersecurity technology is advancing, but too slowly to keep pace with the threat. In short, cybersecurity is losing the escalation battle with cyberattack. The results include mounting damages in the hundreds of billions of dollars, erosion of trust in conducting business and collaboration in cyberspace, and risk of a series of catastrophic events that could cause crippling damage to companies and even entire countries. Cyberspace is unsafe and is becoming less safe every day. The cybersecurity discipline has created useful technology against aspects of the expansive space of possible cyberattacks. Through many real-life engagements between cyber-attackers and defenders, both sides have learned a great deal about how to design attacks and defenses. It is now time to begin abstracting and codifying this knowledge into principles of cybersecurity engineering. Such principles offer an opportunity to multiply the effectiveness of existing technology and mature the discipline so that new knowledge has a solid foundation on which to build. ** Based on "Engineering Trustworthy Systems: A Principled Approach to Cybersecurity, CACM, June 2019. About the speaker: Sami is a senior security architect with over three decades of experience in every stage of cybersecurity including software development, deployments, operations, design, systems engineering, national policy, advanced research, and program management.

Vireshwar Kumar, Security and Privacy of Connected Autonomous Vehicles Mar 11, 2020

The upcoming smart transportation systems which consist of connected autonomous vehicles, are poised to transform our everyday life. The sustainability and growth of these systemsto their full potential will significantly depend on the robustness of these systems against securityand privacy threats. Unfortunately, the communication protocols employed in these systems lackmainstream network security capabilities due to energy constraints of the deployed platforms andbandwidth constraints of the communication medium. In this talk, I will present the results of myefforts in anatomizing the two vital communication protocols employed in the smart transportation:(1) vehicle-to-everything (V2X) communication protocol which is utilized to facilitate wirelesscommunication among connected vehicles, and (2) controller area network (CAN) protocol whichis utilized within an autonomous vehicle to enable real-time control of critical automotivecomponents including brakes. For each of these two protocols, I will first describe the inquisitiveapproach which led to the discovery of the new security vulnerabilities. Then, through theexperiments on real-world systems, I will demonstrate how these vulnerabilities can be exploitedto launch malicious attacks which evade the state-of-the-art defense mechanisms employed inthese systems. I will conclude the talk by discussing novel countermeasures which are requiredto mitigate these fundamental vulnerabilities and prevent their exploitation.

Matt Mickelson, Physics-Based Approaches for creating Cyber Resilient Systems Mar 04, 2020

Our reliance on Cyber-Physical Systems (CPS) is growing. As CPS infrastructure becomes exposed to the contested world through networks, CPS security becomes much more important. In a CPS, the cyber components manage the physical components. We propose that the overall goal for CPS resiliency is to have the physical systems behave properly regardless of fault and disruption. Our approach to CPS resiliency focuses on the physical components. Specifically, the inertia of the physical components provide a natural but limited resilience, and is capable of tolerating short-term disruption without affecting the health and safety of the CPS. This and the fact CPS have a large difference between physical and cyber time scales, enables a unique approach to CPS resiliency. This talk will present our approach of engineering the cyber components to be brittle against attack, which consequently forces cyber attacks and related disruptions to be short-lived and within tolerance of the physical system's inertia. About the speaker: Mr. Mickelson is a Principal in MITRE's Naval Program Division. Matt has spent twenty years integrating emerging technologies, including cyber, AI, and autonomy, to improve some of the world's largest organizations. He has given invited talks in academia and industry. He was a keynote at last years IEEE ICTAI conference and recently an invited speaker for the National Cyber Security Alliance at the NASDAQ.

Yuhong Nan, Semantics-Driven, Learning-Based Privacy Discovery in Mobile Apps Feb 26, 2020

A long-standing challenge in analyzing information leaks within mobile apps is to automatically identify the codeoperating on sensitive data. With all existing solutions relying on System APIs (e.g., IMEI, GPS location) or features of user interfaces (UI), the content from app servers, like user's Facebook profile, payment history, fall through the crack. In this talk, I will introduce ClueFinder, a novel semantics-driven solution for automatic discovery of sensitive user data, including those from the server side. ClueFinder utilizes natural language processing (NLP) to automatically locate the program elements (variables, methods, etc.) of interest, and then performs a learning-based program structure analysis to accurately identify those indeed carrying sensitive content. Using this new technique, we analyzed over 400k popular apps, an unprecedented scale for this type of research. Our findings brings to light the pervasiveness of information leaks, and the channels through which the leaks happen, including unintentional over-sharing across libraries and aggressive data acquisition behaviors. About the speaker: Dr. Yuhong Nan is a Post-Doctoral Research Associate at Purdue University. He earned his Ph.D. in the School of Computer Science from Fudan University, China, with the honor of the 2018 ACM SIGSAC China Doctoral Dissertation Award.

Doug Rapp, Security, Ethics and the End of the World as We Know It Feb 19, 2020

Imagine a world where data is currency. A world where the majority of the data is owned and traded by 6 international data barons who are constantly at war with each other. In this world, rogue AI persecutes whole segments of the population while nations become Petri dishes for mind control. Most people move about daily life oblivious to the knowledge that someone is controlling them, telling them where to go, what to buy, and even how to vote. If you object, millions of cameras track you and pick you out of a crowd where you are intercepted by the authorities and taken off to be reprogrammed. Sound like the Minority Report? The Matrix? Black Mirror? Welcome to 2020. The data revolution and convergence are making the industrial revolution look like a blip on the radar when it comes to change. Join me as we discuss complex issues surrounding ethics in a new world. Who gets to collect and control data? How is AI influenced by data reflecting undesirable human behavior? Should we influence that data to reflect the values we aspire to? If so, who gets to decide the value system? What is the line between advertising and social engineering and is it eroding the concepts of free will and democracy? Is anyone even thinking about this? These are the ethical questions that are being decided (or not decided) today that will shape your tomorrow. About the speaker: Douglas Rapp, CISM is a cybersecurity catalyst. Throughout his career, you will find him squarely at the center of countless firsts.

Char Sample, The Role of Culture in Cybersecurity Feb 12, 2020

Distinguished social psychologist Geert Hofstede observed the "dominance of technology over culture is an illusion. The software of the machines may be globalized, but the software of the minds that use them is not." The role of culture in the thought process is so prevalent, yet unstated, that many cultural beliefs and biases are accepted as truths. These cultural beliefs and biases are commonly infused into behavioral norms identifying behaviors that can be observed. While historically,these observations have taken place in the physical realm, this talk discusses the findings of cultural markers in the cyber realm.Dr. Sample presents and discusses recent interdisciplinary, evidence-based research using culture-based models of various cyber actors (attackers, defenders and victims)to explain observations in cybersecurity behaviors. These studies were performed over the past several years using public data found in the Zone-H archives. The mining of the Zone-H archives with over 10 million records of raw data allowed for research into behaviors, choices and reasons. By using Hofstede's cultural framework to define culture along with some basic inferential statistics, specific digital identifiers were associated with cultural dimensions, allowing for more accurate modeling of cyber actors based on cultural values. The results supported Nisbett's observation that people "think the way they do because of the nature of the societies they live in".The discussion centers on the six dimensions of culture, the values associated with each dimension and examples of those values in cyber space. The six cultural dimensions measure views on values of self-determination, collectivism, aggression,nurturing, uncertain outcomes, holism, instant gratification, and levels of societal openness. The behavioral traits that associate with the cultural values are behavioral traits that are consistent with cyber behaviors. About the speaker: Dr. Char Sample is the Chief Cybersecurity Research Scientist for the Cybercore division at Idaho National Laboratory. Dr. Sample is a visiting academic at the University of Warwick, Coventry, UK and a guest lecturer at Bournemouth University, Rensselaer Polytechnic University and Royal Holloway University. Dr. Sample has over 20 years experience in the information security industry. Dr. Sample's research focuses on deception, and the role of cultural values in cybersecurity events. More recently she has begun researching the relationship between human cognition and machines. Presently Dr. Sample is continuing research on modeling cyber behaviors by culture, other areas of research are data resilience, cyber-physical systems and industrial control systems.

Syed Rafiul Hussain, Automated Reasoning of Security and Privacy of Cellular Networks Feb 05, 2020

Cellular technologies enable a wide array of critical services, from personal communication, autonomous vehicles and telemedicine to critical infrastructures, such as smart grid electricity distribution. Unfortunately, security and user privacy for such complex networks are often considered as afterthoughts. These lead to inadequate security evaluation early on the development cycle that fails to identify missing security and privacy guarantees in protocol designs. To make matters worse, unsafe practices and operational oversights stemming from poor input sanitization and unvetted simplification of complex protocol interactions further contribute to the deviation of deployments from designs. In this talk, I will highlight how my research addresses these problems by developing principled techniques for analyzing design specifications and deployments of complex cellular network protocols. I will first present a new adversarial reasoning technique combining the capabilities of a symbolic model checker and a cryptographic protocol verifier that enabled us to identify 20+ new vulnerabilities in 4G and 5G cellular network design specifications. I will then discuss three new side-channel attacks in 4G and 5G networks uncovered with our dedicated probabilistic reasoning technique. Next, I will talk about a fuzzing technique which is more effective than the state-of-the-art in reasoning about syntactic and semantic correctness of an implementation when binary instrumentation is not realizable and direct feedback on code coverage information is missing. Finally, I will conclude with a discussion on challenges in adapting and scaling our current approaches for a holistic analysis of 5G and next-generation cellular networks, and IoT systems. About the speaker: Syed Rafiul Hussain is a Postdoctoral Researcher in the Department of Computer Science at Purdue University from where he also received his Ph.D. in December 2018. His research interests broadly lie in network and system security with a focus on the fundamental improvement of security and privacy analysis of emerging networks and cyber-physical systems, including cellular networks and Internet-of-Things. His papers have received awards and nominations, including ACSAC'19 distinguished paper award, NDSS'19 distinguished paper award honorable mention, and ACM SIGBED EWSN'17 best paper award nomination. He has been inducted twice in the Hall of Fame Mobile Security Research by GSMA for his contribution in identifying 20+ new protocol flaws in 4G and 5G cellular networks.

Sriharsha Etigowni, Contactless Control Flow Monitoring via Electromagnetic Emanations Jan 15, 2020

Trustworthy operation of industrial control systems depends on secure and real-time code execution on the embedded programmable logic controllers (PLCs). The controllers monitor and control the critical infrastructures, such as electric power grids and healthcare platforms,and continuously report back the system status to human operators. This talk is about Zeus, a contactless embedded controller security monitor solution that will ensure its execution control flow integrity. Zeus leverages the electromagnetic emission by the PLC circuitry during the execution of the controller programs. Zeus's contactless execution tracking enables non-intrusive monitoring of security-critical controllers with tight real-time constraints. Those devices often cannot tolerate the cost and performance overhead that comes with additional traditional hardware or software monitoring modules. Furthermore, Zeus provides an air gap between the monitor (trusted computing base) and the target (potentially compromised) PLC.This eliminates the possibility of the monitor infection by the same attack vectors.Zeus monitors for control low integrity of the PLC program execution. Zeus monitors the communications between the human- machine interface and the PLC and captures the control logic binary uploads to the PLC. Zeus exercises its feasible execution paths, and fingerprints their emissions using an external electromagnetic sensor. Zeus trains a neural network for legitimate PLC execution and uses it at runtime to identify the control flow based on PLC's electromagnetic emissions. Zeus was implemented on a commercial Allen Bradley PLC, which is widely used in industry, and evaluated it on real-world control program executions. Zeus was able to distinguish between different legitimate and malicious executions with 98.9% accuracy and with zero overhead on PLC execution by design. About the speaker: Sriharsha Etigowni is a Post-Doctoral Research Associate at Purdue University. He earned his PhD in Electrical and computer engineering from Rutgers University.

Boyang Wang, Fingerprinting Encrypted Voice Commands on Smart Speakers Dec 04, 2019

Smartspeakers, such as Amazon Echo, have been adopted by millions of users. However,the privacy impacts of smart speakers have not been well examined. We investigatethe privacy leakage of smart speakers under an encrypted traffic analysisattack, referred to as voice command fingerprinting. In this attack, anadversary eavesdrops encrypted voice traffic from and to a smart speaker andinfers which voice command a user says without decrypting encrypted traffic. Wedesign our attacks based on neural networks and collect two large-scaledatasets on Amazon Echo and Google Home by using an automatic traffic crawler. Ourexperimental results show disturbing privacy concerns. Specifically, comparedto 1% accuracy with random guessing, an attacker can infer 92% voice commandscorrectly on Amazon Echo and 99% voice commands correctly on Google Home. Wealso propose a defense to preserve user privacy against this attack with minimallatency and bandwidth overhead. Our simulations show that the proposed defensecan reduce attack accuracy to 1% if an attacker trains neural networks withoriginal traffic and 32% if an attacker adapts and trains neural networks withobfuscated traffic. About the speaker: Boyang Wang is atenure-track Assistant Professor in the Department of Electrical Engineeringand Computer Science at the University of Cincinnati.

Mohsen Minaei, Forgetting the Forgotten: Conceal Content Deletions from Persistent Observers Nov 20, 2019

Most social platforms offer mechanisms allowing users to delete their posts, and a significant fraction of users exercise this right to be forgotten. However, ironically, users' attempt to reduce attention to sensitive posts via deletion, in practice, attracts unwanted attention from stalkers specifically to those (deleted) posts. Thus, deletions may leave users more vulnerable to attacks on their privacy in general. Users hoping to make their posts forgotten face a "damned if I do, damned if I don't" dilemma.In this talk, we will look into two new proposed deletion mechanisms that provide privacy for the deletion of users.In the first approach, in the form of intermittent withdrawals, we present, Lethe, a novel solution to this problem of (really) forgetting the forgotten. If the next-generation social platforms are willing to give up the uninterrupted availability of non-deleted posts by a very small fraction, Lethe provides privacy to the deleted posts over long durations. Furthermore, we introduce Deceptive Deletion, a new decoy mechanism that minimizes the adversarial advantage. Our mechanism creates a two-player min-max game between, an adversary that seeks to classify damaging content among the deleted posts, and a challenger that employs decoy deletions to masquerade real damaging deletions.We evaluate the systems using the Twitter data samples and show that in the presence of a strong adversary our systems protect the privacy of the users' deletions. About the speaker: Mohsen Minaei is a Ph.D. candidate at Purdue University working with Professor Aniket Kate. His research focuses on designing and implementing better privacy-enhancing mechanisms for content deletion and using cryptocurrencies as covert channels to bootstrap the censor circumvention tools. Prior to joining Purdue, he received his bachelor's degree from Sharif University in Tehran.He has completed three internships with the fraud detection and Xbox teams at Microsoft and one with the blockchain team at Visa Research.

Celeste Paul, Hacking Stressed: Frustration, burnout, and the pursuit of happiness Nov 13, 2019

Anyone in this business knows how fun and exciting hacking can be, but also the emotional and physical toll it can take. Mental health is a longstanding dirty secret in the infosec community, and we are just now learning how to talk about it. The wear and tear of everyday stress combined with an 'always on' aspect of an operational environment creates a perfect storm for burning out. While stress can have a negative impact on job performance, my primary concern is on the health and safety of infosec professionals themselves. Not only does stress have short term effects on cognitive abilities and performance, but recurrent acute stress can have long term effects on health (mental and physical) as well as burnout and turnover. There are many sources of stress in infosec operations, some of which can be managed while others are simply the nature of the job. Activities that require long periods of vigilance and creativity will deplete cognitive resources and increase fatigue. Some of these activities have unpredictable results that can increase frustration. Other times, external factors unrelated to the activity itself may introduce new sources of stress that are not normally present. A certain level of stress is to be expected in these operations because they are considerably difficult, have a high risk vs. reward trade-off, and require a significant amount of knowledge and skill. But, how much stress can you take on and still be a happy hacker? In this talk I will discuss why infosec is so stressful, how this stress affects you and your network, and some things you can do about it. I will also discuss lessons learned from my research study of tactical cyber operations that studied fatigue, frustration, and cognitive workload in operators. About the speaker: Dr. Celeste Lyn Paul is a senior researcher for the National Security Agency where she studies the impact of human factors on cybersecurity.

Mitch Parker, Bitcoin and other dreams of utopian thinking-what happens when they meet reality? Oct 30, 2019

Cryptocurrencies are the latest in a series of market bubbles that demonstrate irrational exuberance. In this lecture, Mitch Parker, CISO of IU Health, will go over previous market bubbles, and compare and contrast the differences between the security controls in two peer to peer exchange methods, the current US federal banking system, and Bitcoin. Through this, Mitch will demonstrate the need to have security built into both the technical and non-technical controls of a financial system, and that the power of the system is not just based upon backing by a central bank, but by the series of controls and measures used by the central bank and accounting standards to provide customers the assurance that they are protected. About the speaker: Mitchell Parker, CISSP, is the Executive Director of Information Security and Compliance at IU Health. Mitch has done a significant amount of work in researching the effects of cloud and distributed computing, network-based threats, compliance, and privacy and security requirements on connected health devices.

Chris Jenkins, Moving Target Defense for a Serial Communication Protocol Oct 02, 2019

Nation-state adversaries have shown the ability to disrupt critical infrastructure through cyber-attacks targeting systems of networked, embedded computers. This knowledge raises concern that space systems could face similar threats. This project will research and develop moving target defense algorithms that will add cyber resilience to space systems by improving their ability to withstand cyber-attacks. Most proposed cyber resilience solutions focus on or require detection of threats before mitigative actions can be taken, a significant technical challenge. Our novel approach avoids this requirement while creating informational asymmetry that favors defenders over attackers.We hypothesize that moving target defenses (MTD) can create dynamic, uncertain environments on space systems and be used to defeat cyber threats against these systems. Many proposed solutions focus on or require detection (e.g. anomaly detection, AI, data analytics) before mitigative actions can be taken, a significant technical challenge. We propose a novel approach that avoids this requirement while creating informational asymmetry that favors defenders over attackers. About the speaker: Dr. Chris Jenkins is a principal member of technical staff at Sandia National Laboratories in Albuquerque, NM. His primary responsibility focuses on cybersecurity. Under the cybersecurity umbrella, he focuses on two areas. First, he conducts assessments for a variety of government customers by analyzing devices and systems for vulnerabilities and design flaws. Second, he leads a moving target defense (MTD) research project. His MTD project looks to build cyber resiliency into the design of non-IP based networks. For example, his current research seeks to dynamically change addresses of devices on a non-IP bus where by adversaries have difficulty attacking nodes on the bus. In addition, he works on a high-performance computing (HPC) project called qthreads, which is a general-purpose multithreading library for HPC systems. He plans to port the library to the ASTRA supercomputer purchase by the department of energy. This supercomputer differs as it does not use x86 CPUs. Instead, the supercomputer uses ARM processors based on the ARMv8 architecture.Chris received his bachelor's degree in computer engineering from the University of Illinois at Urbana-Champaign. He finished his PhD at the University of Wisconsin-Madison focusing on accelerating cryptographic algorithms utilizing SIMD execution units on a software-defined radio DSP.

Aritra Mitra, A New Approach to Distributed Hypothesis Testing and Non-Bayesian Learning: Improved Learning Rate and Byzantine Resilience Sep 11, 2019

Consider a scenario where a group of agents, each receiving partially informative private signals, aim to learn the true underlying state of the world that explains their collective observations. These agents might represent a group of individuals interacting over a social network, a team of autonomous robots tasked with detection, or even a network of processors trying to collectively solve a statistical inference problem. To enable such agents to identify the truth from a finite set of hypotheses, we propose a distributed learning rule that differs fundamentally from existing approaches, in that it does not employ any form of ``belief-averaging". Instead, agents update their beliefs based on a min-rule. Under standard assumptions on the observation model and the network structure, we establish that each agent learns the truth asymptotically almost surely. As our main contribution, we prove that with probability 1, each false hypothesis is ruled out by every agent exponentially fast, at a network-independent rate that strictly improves upon existing rates. We then consider a scenario where certain agents do not behave as expected, and deliberately try to spread misinformation. Capturing such misbehavior via the Byzantine adversary model, we develop a computationally-efficient variant of our learning rule that provably allows every regular agent to learn the truth exponentially fast with probability 1. About the speaker: Aritra Mitra received the B.E. degree from Jadavpur University, Kolkata, India, and the M.Tech. degree from the Indian Institute of Technology Kanpur, India, in 2013 and 2015, respectively, both in electrical engineering.

Eugene Spafford, Rethinking Cyber Security Aug 21, 2019

Despite over 50 years of intensive research and experimentation, we still are plagued with systems that are fragile, compromised, and impossible to fully trust. There is near-daily news of compromises and losses, from criminals, nation-state actors, and vandals. The cyber ecosystem we have developed and upon which society is increasingly reliant appears to develop (or have exposed) a new vulnerability as soon as a current one is patched, and old problems keep being introduced. Why do we have such problems? I contend it is traceable to one root cause: we don't understand what cyber security really is. Without good definitions we cannot formulate good metrics. With the absence of good metrics we can't really tell whether we are spending our money and time on useful approaches. Furthermore, the only metrics available to most decision-makers is based simply on cost and speed -- neither of which reflects security or safety. This talk explores this idea in more depth, and should be understandable to non-specialists. I include discussion of some open research problems that -- if successfully addressed -- would lead to improvement of our cyber ecosystem.

Krishna Kavi, Hardware Cybersecurity Attacks and Some Solutions Apr 03, 2019

Recent reports on how side-channel attacks can be used to obtain secret information stored in Cache memories and how current processors that rely on speculative execution of code aids in these side-channel attacks have caught the attention of everyone. Names such as Spectre and Meltdown describe how a well-resourced attacker can discover secret information such as passwords and cyber keys. Since these attacks are applicable most to current processors, made by Intel, AMD and ARM; almost all computing devices (servers, desktops, laptops, cell phones) are vulnerable to such attaches. Several software and some hardware solutions have been suggested and deployed by major vendors; however, most solutions incur performance penalties. In this talk, I will provide an introduction to the architectural features that expose processors to side-channel attacks. I will present some available solutions as well some of our own ideas.

Wei Jiang, Efficient and Constant-Round Secure Comparison through Function Transformation, Dynamic Group Switching and Asymmetric Computation Mar 27, 2019

Within recent years, secure comparison protocols have been proposed using binary decomposition and properties of algebraic fields. These protocols have become increasingly efficient, but their performance has seemingly reached a plateau. We propose a new approach to this problem that transforms the comparison function into comparing specialized summations and takes advantage of dynamically switching domains of secret shares and asymmetric computations for intermediate calculations among the participating parties. As a consequence, according to our analysis, communication and computation costs have been brought to a very low and efficient level. Particularly, the communication costs have been considerably reduced both in order as well as the dominating term's order of magnitude. In addition, we propose a secure protocol under the malicious setting which maintains our transformation and is more efficient than the existing work for common domain sizes. About the speaker: Dr. Wei Jiang is an associate professor in the Department of Electrical Engineering and Computer Science of the University of Missouri-Columbia. He received the Bachelor's degrees in both Computer Science and Mathematics from the University of Iowa in 2002. He received the Ph.D. degree from Purdue University in 2008.

Charles Kamhoua, Game Theoretic Modeling of Cyber Deception in the Internet of Battlefield Things Mar 06, 2019

Most sophisticated cyber attack follow the well-known cyber kill chain. The first step of the cyber kill chain is the reconnaissance phase where attacker probe the network in search of weakness, misconfiguration, vulnerabilities, and identify potential targets before the actual attack start. To this end, the attacker need to collect important information about the characteristics of each devices (i.e., hardware, operating system, applications), the network topology, the different subnet, firewall rules, access control, privilege, the communication protocol at each layer, and the machine learning algorithm on each IoBT devices. The attacker reconnaissance can be summarized by an attack graph in which the node represent vulnerable IoBT devices and the edge show their associated vulnerabilities. This work investigates cyber deception as a complex game in which each player has three concurrent and interdependent objectives. Each players imperfectly monitor (partial observation) other players' action to find out each player's identity, strategies, payoff, available information, capability, and to continuously predict their intent. Each player strategically select to which players to hide particular information (e.g., camouflage). Each player judiciously manipulate other players' perception (e.g., decoy) based on his observed action, estimated capability, and predicted intent. This work examines from the defender's perspective several deception game on an attack graph. The defender goal is to stop the attacker early in the cyber kill chain and prevents the subsequent more dangerous phases. About the speaker: Charles A.

Bowei Xi, A Game Theoretic Approach for Adversarial Machine Learning -- When Big Data Meets Cyber Security Feb 27, 2019

Nowadays more and more data are gathered for detecting andpreventing cyber attacks. Unique to the cyber securityapplications, learning models face active adversaries that try todeceive learning models and avoid being detected. Hence futuredatasets and the training data no longer follow the samedistribution. The existence of such adversarial samplesmotivates the development of robust and resilient adversariallearning techniques. Game theory offers a suitable framework tomodel the conflict between adversaries and defender. We develop agame theoretic framework to model the sequential actions of theadversaries and the defender, allowing players to maximize theirown utilities. For supervised learning tasks, our adversarialsupport vector machine has a conservative decision boundary,whereas our robust deep neural network plays a random strategyinspired by the mixed equilibrium strategy. One the other hand,in real practice, labeling the data instances often requirescostly and time-consuming human expertise and becomes asignificant bottleneck. We develop a novel grid based adversarialclustering algorithm, to understand adversaries' behavior from alarge number of unlabeled instances. Our adversarial clusteringalgorithm is able to identify the normal regions inside mixedclusters, and to draw defensive walls around the center of the normalobjects utilizing game theoretic ideas. Our algorithm alsoidentifies sub-clusters of adversarial samples and the overlapping areaswithin mixed clusters, and identify outliers which may bepotential anomalies.

Meng Yu, Protection against Compromised Operating Systems on ARM Cortex-A Architecture Feb 20, 2019

ARM possessors are being widely used on mobile devices and smart IoT devices. Despite the best efforts, an operating system is too hard to be absolutely secured on both x86 and ARM platforms. We addresse the problem of executing an unmodified application in a compromised OS for ARM platforms. Existing protection mechanisms mainly focus on x86 platform, utilizing SGX of Intel Processors or a hypervisor which is running below an operating system. However, SGX is not available for ARM platform, and hypervisor is an overkill for embedded or IoT settings. We descript how to achieve the security goals on ARM Cortex-A processors using ARM specific designs. We also discuss the threats of side-channels and possible mitigations.

David Ebert, Trustable Information for Security Applications: Visual Analytics for Reliable, Effective Decision Making Feb 06, 2019

Information, not just data, is key to today's security challenges. To solve these security challenges requires not only advancing computer science and big data analytics but requires new analysis and decision-making environments that enable reliable, decisions from trustable, understandable information. These environments are successful when they effectively couple human decision making with advanced, guided analytics in human-computer collaborative discourse and decision making (HCCD). Our HCCD approach builds upon visual analytics, traceable information, and human-guided analytics and machine learning and focuses on empowering the decision maker through interactive visual analytic environments where non-digital human expertise and experience can be combined with state-of-the-art and transparent analytical techniques. When we combine this approach with real-world application-driven research, not only does the pace of scientific innovation accelerate, but impactful change occurs. I'll describe how we have applied these techniques to homeland and community security, resiliency,public safety and disaster management. About the speaker: David Ebert is the Silicon Valley Professor of Electrical and Computer Engineering at Purdue University, a Fellow of the IEEE, interim director of the Center for Education and Research in Information Assurance and Security, and director of the Visual Analytics for Command Control and Interoperability Center (VACCINE), the Visualization Science team of the Department of Homeland Security's Command Control and Interoperability Center of Excellence.

Sanjay Madria, Secure Information Forwarding through Fragmentation in Delay- tolerant Networks Jan 23, 2019

In application environments like international military coalitions or multi-party relief work in a disaster zone, passing secure messages using a Delay Tolerant Network (DTN) is challenging because the existing public-private key cryptographic approaches may not be always accessible across different groups due to the unavailability of Public Key Infrastructure (PKI). In addition, connectivity may be intermittent so finding reliable routes is also difficult. Thus, instead of sending a complete message in a single packet, fragmenting the message, and sending the fragments via multiple nodes can help achieve better security and reliability when multiple groups are involved. Therefore, encrypting messages before fragmentation and then sending both the data fragments and the key fragments (needed for decryption) provide much higher security. Keys are also fragmented as sending the key in a single packet can hamper security if it is forwarded to some corrupt nodes who may try to tamper or drop it. In this talk, I will discuss a scheme to provide improved security by generating multiple key-shares and data fragments, and disseminating them via some intermediate nodes. In this fragmentation process, we also create a few redundant blocks to guarantee higher data arrival rate at the destination when the message drop rate is high like in a DTN environment. The performance evaluation when compared to the closely related scheme like Multiparty Encryption shows the improvement on minimizing the number of compromised messages as well as reduced bandwidth consumption in the network.

Haotian Deng, CEIVE: Combating Caller ID Spoofing on 4G Mobile Phones Via Callee-Only Inference & Verification Jan 09, 2019

Caller ID spoofing forges the authentic caller identity, thus making the call appear to originate from another user. In this paper, we propose CEIVE (Callee-only inference and verification), an effective and practical defense against caller ID spoofing. It is a victim callee only solution without requiring additional infrastructure support or changes on telephony systems. We implement CEIVE on Android phones and test it with all top four US mobile carriers, one landline and two small carriers. It shows 100% accuracy in almost all tested spoofing scenarios except one special, targeted attack case. About the speaker: Haotian Deng is a forth-year PhD student from the department of computer science. His advisor is Prof. Chunyi Peng. His research interests are mainly on mobile networks.

Meng Xu, Precise and Scalable Detection of Double-Fetch Bugs in Kernels Oct 31, 2018

During system call execution, it is common for operating system kernels to read userspace memory multiple times (multi-reads). A critical bug may exist if the fetched userspace memory is subject to change across these reads, i.e., a race condition, which is known as a double-fetch bug. Prior works have attempted to detect these bugs both statically and dynamically. However, due to their improper assumptions and imprecise definitions regarding double-fetch bugs, their multiread detection is inherently limited and suffers from significant false positives and false negatives. For example, their approach is unable to support device emulation, inter-procedural analysis, loop handling, etc. More importantly, they completely leave the task of finding real double-fetch bugs from the haystack of multireads to manual verification, which is expensive if possible at all.In this paper, we first present a formal and precise definition of double-fetch bugs and then implement a static analysis system— DEADLINE—to automatically detect double-fetch bugs in OS kernels. DEADLINE uses static program analysis techniques to systematically find multi-reads throughout the kernel and employs specialized symbolic checking to vet each multi-read for double-fetch bugs. We apply DEADLINE to Linux and FreeBSD kernels and find 23 new bugs in Linux and one new bug in FreeBSD. We further propose four generic strategies to patch and prevent double-fetch bugs based on our study and the discussion with kernel maintainers. About the speaker: Meng Xu is a 5th-year Ph.D. student at School of Computer Science, Georgia Tech, advised by Professor Taesoo Kim. He is a member of SSLab and IISP.

Shiqing Ma, Kernel-Supported Cost-Effective Audit Logging for Causality Tracking Sep 26, 2018

The Linux Audit system is widely used as a causality tracking system in real-world deployments for problem diagnosis and forensic analysis. However, it has poor performance. We perform a comprehensive analysis on the Linux Audit system and find that it suffers from high runtime and storage overheads due to the large volume of redundant events. To address these shortcomings, we propose an in-kernel cache-based online log-reduction system to enable high-performance audit logging. It features a multi-layer caching scheme distributed in various kernel data structures, and uses the caches to detect and suppress redundant events. Our technique is designed to reduce the runtime overhead caused by transferring, processing, and writing logs, as well as the space overhead caused by storing them on disk. Compared to existing log reduction techniques that first generate the huge raw logs before reduction, our technique avoids generating redundant events at the first place. Our experimental results of the prototype KCAL (Kernel-supported Cost-effective Audit Logging) on one-month real-world workloads show that KCAL can reduce the runtime overhead from 40+% to 15-%, and reduce space consumption by 90% on average. KCAL achieves such a large reduction with 4% CPU consumption on average, whereas a state-of-the-art user space log-reduction technique has to occupy a processor with 95+% CPU consumption all the time. About the speaker: Shiqing Ma is a Ph.D. candidate from the Department of Computer Science at Purdue University, advised by Dr. Xiangyu Zhang and Dr. Dongyan Xu.

Doug Rapp, Breaching Water Treatment Plants: Lessons Learned from Complex Exercises Sep 05, 2018

US cybersecurity experts determined that Russian hacking group Dragonfly targeted the United States and European utilities with a cyber espionage campaign from 2015 – 2017. This government sponsored group was able to successfully infiltrate core control systems. Cold War espionage methodologies such as "sleeper cells" are now being executed in the cyber domain. Industrial firms including power and water providers have proven to be susceptible to attacks and disruptions that could be used during a significant geopolitical conflict. Antiquated industrial control devices now connected to the internet make utilities in even the most advanced countries susceptible to everyone from hacktivists to cyber criminals to nation states. In these times, the question has shifted from "can they?" to "when will they?". Using Indiana's groundbreaking cybersecurity exercise Crit-Ex as an example, we explore exactly how vulnerable of utilities really are and how insights into incident response and resiliancy are discovered through complex training and exercises.

Abe Clements, Protecting Bare-metal Embedded Systems from Memory Corruption Attacks Aug 22, 2018

Embedded systems are used in every aspect of modern life. The Internet of Things is comprised of millions of these interconnected systems many of which are low cost bare-metal systems, executing without an operating system. These systems rarely employ security protections. Their development assumptions of unrestricted access to all memory and instructions and constraints on runtime, energy, and memory makes applying protections particularly challenging. I will present recent two recent techniques EPOXY (IEEE S&P 2017) and ACES (USENIX Security 2018), that harden bare-metal systems against memory corruption attacks. EPOXY is an LLVM based embedded compiler that uses a novel technique, called privilege overlaying, wherein operations requiring privileged execution are identified and only these operations execute in privileged mode. This provides the foundation on which code-integrity, adapted control-flow hijacking defenses, and protections for sensitive IO are applied. EPOXY also employs fine-grained randomization schemes, that work within the constraints of bare-metal systems to provide further protection against control-flow and data corruption attacks.These defenses prevent code injection attacks and ROP attacks from scaling across large sets of devices. EPOXY's evaluation on case study applications shows that EPOXY has, on average, a 1.8% increase in execution time and a 0.5% increase in energy usage.ACES is another LLVM-based compiler that automatically infers and enforces inter-component isolation on bare-metal systems, thus applying the principle of least privileges. ACES takes a developer-specified compartmentalization policy and then automatically creates an instrumented binary that isolates compartments at runtime, while handling the hardware limitations of bare-metal embedded devices. ACES evaluation shows that ACES' compartments can have low runtime overheads (13% on our largest test application), while using 59% less Flash, and 84% less RAM than the Mbed uVisor—the current state-of-the-art compartmentalization technique for bare-metal systems. ACES‘ compartments protect the integrity of privileged data, provide control-flow integrity between compartments.

Debajyoti Das, Anonymity Trilemma : Strong Anonymity, Low Bandwidth Overhead, Low Latency – Choose Two. Apr 11, 2018

Over the last three decades, several anonymous communication (AC) protocols have been proposed towards improving users' privacy over the internet. Among those, the Tor protocol has been particularly successful. Thanks to its low communication latency and low bandwidth overhead, Tor today is employed by millions of users worldwide. Nevertheless, its anonymity is known to be broken in the presence of global adversaries. AC protocols like the dining cryptographers network provide anonymity even in the presence of global adversaries at the expense of bandwidth overhead, while others such as the mixing network designs improve anonymity at the expense of higher latency.In this work, we investigate the fundamental constraints of anonymous communication (AC) protocols. We analyze the relationship between bandwidth overhead, latency overhead, and sender anonymity or recipient anonymity against the global passive (network-level) adversary. We confirm the trilemma that an AC protocol can only achieve two out of the following three properties: strong anonymity (i.e., anonymity up to a negligible chance), low bandwidth overhead, and low latency overhead.We further study anonymity against a stronger global passive adversary that can additionally passively compromise some of the AC protocol nodes. For a given number of compromised nodes, we derive necessary constraints between bandwidth and latency overhead whose violation make it impossible for an AC protocol to achieve strong anonymity. We analyze prominent AC protocols from the literature and depict to which extent those satisfy our necessary constraints. Our fundamental necessary constraints offer a guideline not only for improving existing AC systems but also for designing novel AC protocols with non-traditional bandwidth and latency overhead choices.

Pedro Moreno-Sanchez, Mind Your Credit: Assessing the Health of the Ripple Credit Network Mar 21, 2018

The Ripple credit network has emerged as the payment backbone withindisputable advantages for financial institutions and the remittanceindustry. Ripple's market capitalization is currently third only toBitcoin and Ethereum. Its path-based IOweYou (IOU) settlements acrossdifferent currencies conceptually distinguishes the Ripple blockchainfrom the cryptocurrencies (such as Bitcoin) and makes it highly suitableto an orthogonal yet vast set of applications in the remittance worldand beyond. In this talk, I present our recent study of the structure and evolutionof the Ripple network since its inception, and our research resultsregarding its vulnerability to attacks that harm the IOU credit of itswallets. We find that about 13M USD are at risk in the current Ripplenetwork due to inappropriate configuration of the rippling flag oncredit links that paves the way to undesired redistribution of creditacross those links. Although the Ripple network has grown around a fewhighly connected hub (gateway) wallets that make the core of the networkand provide high liquidity to users, such credit link distributionresults in a user base of around 112,000 wallets that can be financiallyalienated by as few as 10 highly connected gateway wallets. Indeed,today about 4.9M USD cannot be withdrawn by their owners from the Ripplenetwork due to PayRoutes, a gateway tagged as faulty by the Ripplecommunity. Finally, we observe that stale exchange offers pose a realproblem, and exchanges (market makers) have not always been vigilantabout periodically updating their exchange offers according to currentreal-world exchange rates. For example, stale offers were used by 84Ripple wallets to gain more than 4.5M USD from mid-July to mid-August2017. Our findings should prompt the Ripple community to improve thehealth of the network by educating its users on increasing theirconnectivity, and by appropriately maintaining the credit limits,rippling flags, and exchange offers on their IOU credit links. About the speaker: Pedro Moreno-Sanchez is a PhD student in the Department of ComputerScience at Purdue University. His advisor is Prof. Aniket Kate. Hiscurrent research focuses on the areas of security, privacy andreliability of credit network based systems such as Ripple.

Nathan Burrow, CFIXX -- Object Type Integrity for C++ Mar 07, 2018

C++ relies on object type information for dynamic dispatch and casting. The association of type information to an object is implemented via the virtual table pointer, which is stored in the object itself. As C++ has neither memory nor type safety, adversaries may therefore overwrite an object's type. If the corrupted type is used for dynamic dispatch, the attacker has hijacked the application's control flow. This vulnerability is widespread and commonly exploited. Firefox, Chrome, and other major C++ applications are network facing, commonly attacked, and make significant use of dynamic dispatch. Control- Flow Integrity (CFI) is the state of the art policy for efficient mitigation of control-flow hijacking attacks. CFI mechanisms determine statically (i.e., at compile time) the set of functions that are valid at a given call site, based on C++ semantics. We propose an orthogonal policy, Object Type Integrity (OTI), that dynamically tracks object types. Consequently, instead of allowing a set of targets for each dynamic dispatch on an object, only the single, correct target for the object's type is allowed. To show the efficacy of OTI, we present CFIXX, which enforces OTI. CFIXX enforces OTI by dynamically tracking the type of each object and enforcing its integrity against arbitrary writes. CFIXX has minimal overhead on CPU bound applica- tions such as SPEC CPU2006 — 4.98%. On key applications like Chromium, CFIXX has negligible overhead on JavaScript benchmarks: 2.03% on Octane, 1.99% on Kraken, and 2.80% on JetStream. We show that CFIXX can be deployed in conjunction with CFI, providing a significant security improvement. About the speaker: Nathan Burow is a fifth year PhD student in systems security, working for his Mathias Payer in the HexHive group within the Computer Science department at Purdue University. His research focuses on modifying the LLVM compiler infrastructure to secure the C / C++ programming languages.

Adil Ahmad, OBLIVIATE: A Data Oblivious File System for Intel SGX Feb 14, 2018

Trusted computing is the key component in achieving confidentiality and integrity in modern cloud environments. Commodity trusted hardware such as Intel SGX and ARM Trustzone allow programs to execute and store sensitive data in secure memory regions. It is envisioned that these systems will enable important applications from trusted data analytics and Private Information Retrieval (PIR) in the cloud to content protection and secure financial services in mobile settings.This talk deals with the security aspects of SGX programs in accessing a key system resource, files. Our focus would be on concrete attacks against existing SGX filesystem implementations through well-known side-channels, as well as the design and implementation of an oblivious filesystem to thwart aforementioned attacks. Our solution, Obliviate, mitigates this threat using ORAM, a cryptographic primitive which enables secure data access even when the attacker can observe all memory interactions. We show that a naive implementation of ORAM within SGX opens vulnerability to other attacks and induces a degree of overhead. Therefore, Obliviate develops a secure implementation of ORAM using CMOV, an x86-based instruction, and employs other SGX-specific optimizations. We show that Obliviate can secure all filesystem interactions while providing a performance improvement of 6 − 8× over a baseline scheme. Potential use-cases of Obliviate include real-world cloud applications such as web servers, databases and personal cloud storage. This work will appear in NDSS 2018. About the speaker: Adil Ahmad is a PhD student with the Department of Computer Science at Purdue University, being advised by Prof. Byoungyoung Lee. His primary research interests are in the field of systems and security with a particular focus on hardware-assisted trusted computing.

Matt Dimino, State of Cybersecurity in Healthcare Jan 31, 2018

The public health sector cannot deliver efficient and safe patient care without digital interconnectivity among devices. If the healthcare system is connected, but insecure, the interconnectivity could betray patient safety, subjecting patients to uncalculated and unnecessary risks with insurmountable costs, including death. Our nation must realize the dangers imposed on patients due to the reliance on interconnectivity amongst devices and information systems. Healthcare delivery organizations are often seen and titled as safe places, places for healing, and places we trust. These entities are a repository for our most sacred personal information as well as a harbor for some of the most technologically advanced equipment; thus they have become easy targets for threat actors.Real cases of protected health information theft, ransomware, and targeted nation-state hacking prove that our nation's healthcare systems, data, devices, and reputation are vulnerable. This presentation aims at depicting the current state of cybersecurity in healthcare delivery organizations as well as at understanding the main threats organizations face, discussion the ecosystem, industry-specific pitfalls, and the patient health attack model. About the speaker: Matt Dimino is on a mission to help our nation's healthcare and public health sector critical infrastructure recognize and prepare for tomorrows cyber threat landscape.

Ben Harsha, The Economics of Offline Password Cracking Jan 17, 2018

Password leaks have become an unfortunately common occurrence, with billions of records leaked in the past few years. In this work we develop and economic model to help predict how many user passwords such an attacker will crack after such a breach. Our analysis indicates that currently deployed key stretching mechanisms such as PBKDF2 and BCRYPT provide insufficient protection for user passwords. In particular, our analysis shows that a rational attacker will crack 100% of passwords chosen from a Zipf's law distribution and that Zipf's Law accurately models the distribution of most user passwords. This dismal claim holds even if PBKDF2 is used with 100,000 hash iterations (10 times greater than NIST's minimum recommendation). On a positive note our analysis demonstrates that memory hard functions (MHFs) such as SCRYPT or Argon2i can significantly reduce the damage of an offline attack. Based on our analysis we advocate that password hashing standards should be updated to require the use of memory hard functions for password hashing and disallow the use of non-memory hard functions such as BCRYPT or PBKDF2. About the speaker: Ben Harsha is a Computer Science Ph.D. student advised by Jeremiah Blocki. He currently works on password security and cryptographic hash functions. Before coming to Purdue in 2015 he also worked on distributed sensor networks at Argonne National Lab, as well as neural network optimization and computer science education methods at DePauw University.

Abhishek Ray, Ad-Blockers: Extortionists or Digital Age Robin Hoods? Nov 15, 2017

Intrusive online advertising has given birth to the trend of ad-blockers. Initially dismissed by the online advertising industry as inconsequential, ad-blockers have evolved from a mere plugin tool on browsers to full-fledged platforms that derive benefits from certifying quality of advertisers and reducing disutility of users from intrusive activities such as user tracking. However, are ad-blocking platforms the optimal solution to improving user experience online? There is no clear answer. User experience advocates term this as yet another way to target users online. Industry advocates accuse ad-blockers of using an extortion-based business model, built on fleecing advertisers. Through our game theoretic model, we inform policy-makers on this problem and establish the optimal pricing policy for such ad-blocking platforms. In addition, we theorize the socially optimal pricing policies of advertising supported content platforms and establish how such platforms should price participation from users, given the obvious disutility of advertising they are exposed to. About the speaker: Abhishek Ray is a 4th year PhD candidate in Management Information Systems at Krannert School of Management, Purdue University. His research interests lie at the intersection of Economics, Digital Business & Engineering. He holds an MS in Economics and MS in Industrial Engineering from Purdue University.

Nikita Borisov, Refraction Networking: Censorship Circumvention in the Core of the Internet Nov 08, 2017

Internet users around the world are facing censorship. To access blocked websites, they use circumvention services that most commonly consist VPN-like proxies. The censors, in turn, try to block such proxies, creating a sort of cat-and-mouse game. Refraction networking takes a different approach by placing refracting routers inside ISP networks. By spending a special signal, a user can ask a router to refract *any* connection that transits the ISP to another, blocked destination, in a process that is undetectable by the censor. To prevent such connections, the censor would need to block all traffic from reaching that ISP, which considerably raises the cost of censorship.I will discuss the design of refraction networking and how it achieves the properties above. I will also discuss the results of our a pilot deployment of refraction networking two ISPs handling an aggregate of nearly 100 Mbps traffic, which provided censorship circumvention to 50,000 users in a country with heavy Internet censorship. I will close by discussing some future research issues in the space. About the speaker: Nikita Borisov is an associate professor at the University of Illinois atUrbana-Champaign. His research is interests are online privacy and networksecurity, with recent work on anonymous communication, censorship resistance,analysis of encrypted traffic, and protocols for secure communication.

Jerome Edge, Applying commercial best practices to DoD risk management to offer suggestions how to move from risk avoidance to cost effective risk management Oct 25, 2017

The Department of Defense has mandated a risk management rather than risk avoidance approach in Cybersecurity. All Department of Defense programs are being directed to the Risk Management Framework (RMF) process. No Cyber system can be 100% secure. RMF mandates that we clearly determine the "value" of assets, such as information and intellectual property, and design systems to properly protect those assets. The commercial domain embraces the mantra that an organization should not spend more to protect the asset than the asset is worth. This presentation will provide an overview of RMF as applied to a specific publically available case study and highlight that utilizing commercial best practices can reduce cost of delivered systems to DoD. About the speaker: Jerome Edge is a System Security Engineer who works for Lockheed Martin Corporation to provide secure solutions to DoD Information Systems. Jerome has worked at Lockheed Martin Aeronautics Company for 20 plus years with over 10 years in a Security Engineering role on a multitude of aeronautical aircraft.Jerome is a Certified Information System Security Professional (CISSP) and Security + and looking forward to obtaining a certification in Certified Ethical Hacker (CEH).Jerome holds a Bachelor of Science degree in Electrical Engineering from University of Tennessee (1997) and a Master of Science degree in Security Engineering from Southern Methodist University (2010).

Tianhao Wang, Locally Differential Private Protocols for Frequency Estimation Oct 18, 2017

Protocols satisfying Local Differential Privacy (LDP) enable parties to collect aggregate information about a population while protecting each user's privacy, without relying on a trusted third party. LDP protocols (such as Google's RAPPOR) have been deployed in real-world scenarios. In these protocols, a user encodes his private information and perturbs the encoded value locally before sending it to an aggregator, who combines values that users contribute to infer statistics about the population. In this paper, we introduce a framework that generalizes several LDP protocols proposed in the literature. Our framework yields a simple and fast aggregation algorithm, whose accuracy can be precisely analyzed. Our in-depth analysis enables us to choose optimal parameters, resulting in two new protocols (i.e., Optimized Unary Encoding and Optimized Local Hashing) that provide better utility than protocols previously proposed. We present precise conditions for when each proposed protocol should be used, and perform experiments that demonstrate the advantage of our proposed protocols. About the speaker: Tiahhao Wang is a Ph.D. candidate at Purdue University working with Professor Ninghui Li. His research focuses on the practical aspects of privacy and security. Tiahhao's research has been published at top tier security venues such as USENIX and CCS, and his Erdos number is 3. His current research projects include local differential privacy and electronic voting.

Jeremiah Blocki, Memory Hard Functions and Password Hashing Oct 11, 2017

In the last few years breaches at organizations like Yahoo!, Dropbox, Lastpass, AshleyMadison and Adult FriendFinder have exposed billions of user passwords to offline brute-force attacks. Password hashing algorithms are a critical last line of defense against an offline attacker who has stolen password hash values from an authentication server. An attacker who has stolen a user's password hash value can attempt to crack each user's password offline by comparing the hashes of likely password guesses with the stolen hash value. Because the attacker can check each guess offline it is no longer possible to lockout the adversary after several incorrect guesses. The attacker is limited only by the cost of computing the hash function. Offline attacks are increasingly commonplace and dangerous due to weak password selection and improved cracking hardware such as a GPU, Field Programmable Gate Array (FPGA) or an Application Specific Integrated Circuit (ASIC). A secure password hashing algorithm should have the properties that (1) it can be computed quickly (e.g., at most one second) on a personal computer, (2) it is prohibitively expensive for an attacker to compute the function millions or billions of times to crack the user's password even if the attacker uses customized hardware. The first property ensures that the password hashing algorithm does not introduce an intolerably long delay for the user during authentication, and the second property ensures that an offline attacker will fail to crack most user passwords. Memory hard functions (MHFs), functions whose computation require a large amount of memory, are a promising cryptographic primitive to enable the design of a password hashing algorithm achieving both goals. The talk will introduce and motivate the notion of memory hard functions and survey recent advances in the theory of MHFs. These results include (1) an attack on the Argon2i MHF, winner of the password hashing competition, which could reduce an amortized costs for a password attacker, (2) security lower bound for SCRYPT MHF and (3) construction of the first provably secure data-independent memory hard function. About the speaker: Jeremiah Blocki is an Assistant Professor in Computer Science at Purdue University. Jeremiah completed his PhD on Usable Human Authentication at Carnegie Mellon University under the supervision of Manuel Blum and Anupam Datta. Prior to joining Purdue he also spent a time at Microsoft Research New England as a postdoc and as a research fellow at the Simon's Institute for the Theory of Computing. Professor Blocki has made fundamental contributions to the theory of memory hard functions --- an important cryptographic primitive which can be used to protect low entropy secrets such as passwords against brute force attacks. Broadly, his research interests include cryptography, usable authentication, passwords, differential privacy, game theory and learning theory. One of his more ambitious research goals is to develop cryptographic protocols that are so simple that a human could execute them without receiving assistance from a trusted computer.

Xiaonan Guo, Friend or Foe? Your Wearable Devices Reveal Your Personal PIN Oct 04, 2017

The proliferation of wearable devices, e.g., smartwatches and activity trackers, with embedded sensors has already shown its great potential on monitoring and inferring human daily activities. In this talk, I will present a serious security breach of wearable devices in the context of divulging secret information (i.e., key entries) while people accessing key-based security systems. Existing methods of obtaining such secret information relies on installations of dedicated hardware (e.g., video camera or fake keypad), or training with labeled data from body sensors, which restrict use cases in practical adversary scenarios. I will show that a wearable device can be exploited to discriminate mm-level distances and directions of the user's fine-grained hand movements, which enable attackers to reproduce the trajectories of the user's hand and further to recover the secret key entries. About the speaker: Xiaonan Guo received his Ph.D. degree in computer science and engineering from the Hong Kong University of Science and Technology under the guidance of Prof. Lionel M. Ni in 2013. Prior to joining IUPUI as an Assistant Professor at CIT department, he was a research associate working with Prof.Yingying Chen in the Electrical and Computer Engineering Department at Stevens Institute of Technology.

Shiqing Ma, MPI: Multiple Perspective Attack Investigation with Semantic Aware Execution Partitioning Aug 23, 2017

Operating system level auditing is one of the most important forensics techniques. With operating system level audit systems, e.g., the Linux audit system, investigators can generate attack causal graphs by analyzing the causal relationships between the logged events. However, traditional techniques usually generate large and inaccrute causal graphs. This is because applications are not aware of the existence of the OS level audit systems, and can not provide its own context information. To solve this problem, we propose MPI (short for Multiple Perspective attack Investigation), a semantics aware program annotation and instrumentation technique to partition process executions based on the application specific high level task structures. It converts current applications to be provenance-aware, generates execution partitions with rich semantic information and provides multiple perspectives of an attack. We develop a prototype and integrate it with three different provenance systems: the Linux Audit system, ProTracer and the LPM-HiFi system. The evaluation results show that our technique generates simple and accurate attack graphs with rich high-level semantics and has much lower space and time overheads. About the speaker: Shiqing Ma is a Ph.D. student from the Department of Computer Science at Purdue University, advised by Dr. Xiangyu Zhang and Dr. Dongyan Xu. His research focuses on system and software security especially data provenance problems.

He is a recipient of two Distinguished Paper Awards from NDSS 2016 and USENIX Security 2017.

Adam Bates, Enabling Trust and Efficiency in Provenance-Aware Systems Apr 26, 2017

In a provenance-aware system, mechanisms gather and report metadata that describes the history of each object being processed on the system, allowing users to understand how data objects came to exist in their present state. However, little attention has been given to securing provenance-aware systems. Provenance itself is a ripe attack vector, and its authenticity and integrity must be guaranteed before it can be put to use. In this talk, I will detail our efforts to bring trustworthy data provenance to computing systems. These efforts have led to the design and implementation of a provenance-aware operating system anchored in trusted hardware, and a mechanism that leverages the confinement properties provided by Mandatory Access Controls to perform efficient policy-based provenance collection. Using these architectures, I will demonstrate that provenance is an invaluable tool for combating critical security threats including data exfiltration, SQL injection, and even binary exploitation. By addressing key security and performance challenges, this work paves the way for the further proliferation of provenance capabilities. About the speaker: Adam Bates is an Assistant Professor in the Computer Science Department at the University of Illinois at Urbana-Champaign. He received his PhD from the University of Florida, where he was advised by Professor Kevin Butler in the study of computer systems and cyber security.

As we push computers to "the edge" building an increasingly complex world of interconnected systems and devices, security and privacy continue to dominate the national conversation. The Defense Science Board in its 2017 report, Task Force on Cyber Defense, provides a sobering assessment of the current vulnerabilities in the U.S. critical infrastructure and the systems that support the mission essential operations and assets in the public and private sectors."…The Task Force notes that the cyber threat to U.S. critical infrastructure is outpacing efforts to reduce pervasive vulnerabilities, so that for the next decade at least the United States must lean significantly on deterrence to address the cyber threat posed by the most capable U.S. adversaries. It is clear that a more proactive and systematic approach to U.S. cyber deterrence is urgently needed…"There is an urgent need to further strengthen the underlying systems, component products, and services that we depend on in every sector of the critical infrastructure—ensuring those systems, components, and services are sufficiently trustworthy and provide the necessary resilience to support the economic and national security interests of the United States. NIST Special Publication 800-53 (Revision 5) responds to the call by the Defense Science Board by embarking on a proactive and systemic approach to develop and make available to a broad base of public and private sector organizations, a comprehensive set of safeguarding measures for all types of systems, including general purpose computing systems, cyber-physical systems, cloud and mobile systems, industrial/process control systems, and IoT devices. Those safeguarding measures include security and privacy controls to protect the critical and essential operations and assets of organizations and the personal privacy of individuals. The ultimate objective is to make the systems we depend on more penetration resistant to attacks; limit the damage from attacks when they occur; and make the systems resilient and survivable. About the speaker: Ron Ross is a Fellow at the National Institute of Standards and Technology. His focus areas include information security, systems security engineering, and risk management. Dr. Ross leads the Federal Information Security Modernization Act (FISMA) Implementation Project, which includes the development of security standards and guidelines for the federal government, contractors, and the United States critical infrastructure.

Limin Jia, Information Flow Security in Practical Systems Apr 12, 2017

Users routinely type sensitive data such as passwords, credit card numbers, and even SSN into their mobile phone apps and browsers. Rich functionality combined with weak security mechanisms makes protecting users' data a challenging. In this talk, I will present a few case studies of applying information flow security to protecting users' data in Android, the Chromium browser, and the IFTTT framework. For these systems, we show that dynamic coarse-grained taint tracking, even though it allows implicit flows, can be retrofitted into existing systems to defend users' data from common attacks. I will explain the challenges in striking a balance between preserving key functionality of legacy systems and ensuring formally provable security guarantees and discuss how different modeling techniques affect noninterference proofs. About the speaker: Dr. Jia is an Assistant Research Professor in the ECE Department at Carnegie Mellon University. Dr. Jia received her PhD in Computer Science from Princeton University. She received her BE in Computer Science and Engineering from the University of Science and Technology in China. Dr. Jia's research interests are in formal aspects of software security, in particular, applying formal approaches to constructing software systems with known security guarantees.

Scott Carr, DataShield: Configurable Data Confidentiality and Integrity Mar 29, 2017

Applications written in C/C++ are prone to memory corruption, which allows attackers to extract secrets or gain control of the system. With the rise of strong control-flow hijacking defenses, non-control data attacks have become the dominant threat. As vulnerabilities like HeartBleed have shown, such attacks are equally devastating.Data Confidentiality and Integrity (DCI) is a low-overhead non-control-data protection mechanism for systems software. DCI augments the C/C++ programming languages with annotations, allowing the programmer to protect selected data types. The DCI compiler and runtime system prevent illegal reads (confidentiality) and writes (integrity) to instances of these types. The programmer selects types that contain security critical information such as passwords, cryptographic keys, or identification tokens. Protecting only this critical data greatly reduces performance overhead relative to complete memory safety.Our prototype implementation of DCI, DataShield, shows the applicability and efficiency of our approach. For SPEC CPU2006, the performance overhead is at most 16.34%. For our case studies, we instrumented mbedTLS, astar, and libquantum to show that our annotation approach is prac- tical. The overhead of our SSL/TLS server is 35.7% with critical data structures protected at all times. Our security evaluation shows DataShield mitigates a recently discovered vulnerability in mbedTLS. About the speaker: Scott A. Carr is a PhD Candidate in Computer Science at Purdue University, where he works with his advisor Mathias Payer in the HexHive research group. His research interests are security, programming languages, and program analysis. Scott's thesis topic is mitigating vulnerabilities in systems software written in C/C++ using compiler-based techniques.

Tawei (David) Wang, CIO Risk Appetite and Information Security Management Mar 22, 2017

After a series of recent high profile information security breach incidents, the role of Chief Information Officers, particularly their role in information security risk management, has been in a heated debate among practitioners. However, little is known in academic literature about how a CIOs' risk aversion level affects the effectiveness of information security management. Using reported information security breach incidents during 2003-2015, this study examines how a CIO's risk aversion level is associated to the possibility of information security incidents. In addition, we investigate the moderating effect of CEOs' risk aversion level and whether the CIO is on the board on the aforementioned effect. Our preliminary results show that a CIO's risk aversion level is significantly associated with a lower likelihood of information security breaches. We further document that such association varies depending on types of security breaches. About the speaker: Tawei (David) Wang is currently an Assistant Professor at DePaul University. He received his Ph.D. from Krannert Graduate School of Management, Purdue University. Before joining DePaul University, he was a faculty member at the University of Hawaii at Manoa and National Taiwan University.

Yonghwi Kwon, A2C: Self Destructing Exploit Executions via Input Perturbation Feb 22, 2017

Malicious payload injection attacks have been a serious threat to software for decades. Unfortunately, protection against these attacks remains challenging due to the ever increasing diversity and sophistication of payload injection and triggering mechanisms used by adversaries.In this talk, I will present A2C, a system that provides general protection against payload injection attacks. A2C is based on the observation that payloads are highly fragile and thus any mutation would likely break their functionalities. A2C mutates inputs from untrusted sources. Malicious payloads that reside in these inputs are hence mutated and broken. To assure that the program continues to function correctly when benign inputs are provided, A2C divides the state space into exploitable and post-exploitable sub-spaces, where the latter is much larger than the former, and decodes the mutated values only when they are transmitted from the former to the latter. A2C does not rely on any knowledge of malicious payloads or their injection and triggering mechanisms. Hence, its protection is general. We evaluate A2C with 30 real-world applications, including apache on a real-world work-load, and our results show that A2C effectively prevents a variety of payload injection attacks on these programs with reasonably low overhead. About the speaker: Yonghwi Kwon is a PhD student in the Department of Computer Science at Purdue University. His research interests include dynamic/static binary analysis, reverse-engineering, and system security. In particular, he is interested in solving security and debugging problems using dynamic binary analysis and translation techniques.

Ashish Hota, Behavioral and Computational Aspects of Network Security Games Feb 15, 2017

In this talk, we will leverage the framework of game theory to understand the effects of decentralized decision-making on the robustness and security of large-scale networked systems. In the first part of this talk, we will consider a setting where each node in the network is an independent decision maker who wants to protect itself, and the probability of attack on a node is a function of the security investment by the node and its immediate neighbors in the network. Accordingly, the security investment of a node depends on its position in the network and its perception of attack probability. We will investigate the impact of certain empirically established behavioral biases, that affect how users perceive probabilities of risky outcomes, on the security investment decisions of the nodes. We will further characterize the structures of networks that maximize and minimize the expected fraction of nodes that are successfully attacked at the Nash equilibrium of the game, respectively. In the second part of the talk, we will consider a setting where each decision maker is responsible for defending multiple nodes in the network, and strategic attacker(s) launch multi-stage attacks that spread through the network. We will show that the problem of computing the best response for a defender can be formulated as a convex optimization problem. We will then illustrate the application of this framework in problems that arise in networked cyber-physical systems. About the speaker: Ashish R. Hota is currently a Ph.D. candidate in the School of Electrical and Computer Engineering at Purdue University. He received B.Tech and M.Tech degrees in Electrical Engineering from Indian Institute of Technology (IIT) Kharagpur in 2012. His research interests are in the areas of game theory, network economics, behavioral decision theory, security of networked systems and queueing games.

Vincent Urias, Network Deception as a Threat Intelligence Platform Feb 01, 2017

The threat landscape is changing significantly; complexity and rate of attacks is ever increasing, and the network defender does not have enough resources (people, technology, intelligence, and context) to make informed decisions. The need for network defenders to develop and create proactive threat intelligence is on the rise. Network deception may provide analysts the ability to collect raw intelligence about threat actors as they reveal their Tools, Tactics, and Procedures (TTP). This increased understanding of the latest cyber-attacks would enable cyber defenders to better support and defend the network, thereby increasing the cost to the adversary by making it more difficult to successfully attack an enterprise. This talk will discuss our deception framework, we have created a live, unpredictable, and adaptable Deception Environment leveraging virtualization/cloud technology, software defined networking, introspection and analytics. The environment not only provides the means to identify and contain the threat, but also facilitates the ability to study, understand, and develop protections against sophisticated adversaries. By leveraging actionable data, in real-time or after a sustained engagement, the Deception Environment may be easily modified to interact with and change the perception of the adversary on-the-fly. This ability to change what and where the attacker is on the network, as well as change and modify the content of the adversary on exfiltration and infiltration, is the defining novelty of our Deception Environment. About the speaker: Vincent was raised by his grandparents, both originally from Guatemala who immigrated to the U.S. in the 1960's. As a family, they moved from Manhattan to Albuquerque, New Mexico when Vincent was six years old. Dedicated to their grandchild and his upbringing, they taught him to take responsibility for his own life, to give back to his community and to his country. A curious boy who broke things while taking them apart to see how they worked, he was also entrepreneurial starting a candy selling business in elementary school. He saved his money and bought things that his grandparents could not afford, like a soldering kit. Vincent grew up in neighborhood labeled the "War Zone" made up of hard working but largely impoverished immigrants with its share of violence and gang problems as well as remarkable diversity. Vincent stayed out of trouble becoming involved in extracurricular activities and one of those, the Upward Bound Program gave him the opportunity to spend a high school summer at the University of New Mexico taking classes in math, literature, science and electives. Vincent took advantage of many opportunities this program would offer. His entrepreneurial spirit got him taking community college classes while still in high school and in his sophomore year, he was accepted for an internship at Sandia National Laboratories in its computer support unit. With the support of mentors, he was soon one of the go-to techs fixing computers and getting networks running again. A CyberCorps Scholarship for Service allowed him to stay at Sandia after graduation. He continued to excel and taking associated undergraduate and graduate level internships while earning his bachelor's and master's degree in computer science from New Mexico Tech. Today, Vincent Urias is a computer engineer, and Principal Member of Technical Staff in Sandia's Cyber Analysis Research Development Department continuing to make major contributions to Sandia's cyber defense programs, especially in the simulation of complex networks, in developing innovative cyber security methods, and in designing exercise scenarios that test the limits of current network security. This work is helping Sandia's customers anticipate current and emerging security threats and make critical decisions about their investments. Vincent and his team use technologies to conduct cyber defense exercises in partnership with the U.S. Department of Defense, and to support national security in collaboration with colleagues at other U.S. Department of Energy national laboratories, Department of Defense national laboratories, and the U.S. military.Vincent gives back to the community in a variety of ways, providing guidance and inspiration to college interns in the lab's Center for Cyber Defenders, he supports building computer labs for local organizations and is also helping to create an Urban Wildlife Refuge in Albuquerque's South Valley among other things. Vincent is currently pursuing his Ph.D. in computer science, at New Mexico Tech. He was honored by GMiS with a HENAAC Luminary Award in October of 2016.

Jean Camp, Changing the Economics of the Network Jan 25, 2017

BGP enables as a network of networks, and is also a network of trust. The most clear instantiation of that trust is the updating of router tables based on unsubstantiated announcements. The positive result of this trust is that the network can be extremely responsive to failures, and recover quickly. Yet the very trust that enables resilience creates risks from behavior lacking either technical competence or benevolence. Threats to the control plane have included political interference, misguided network configurations, and other mischief. Our goal is to look at solutions that treat BGP as an economic political artifact that embeds trust, and change the game in BGP defense.One step is to classify route updates along a continuum of trust, exploring new algorithms that will give a measure of integrity assurance to BGP updates. We have explored the application of machine learning techniques with the variety of data available (technical, rates of change, economic, and geopolitical) as network topology is changed via BGP updates in order to generate probabilistic (not only cryptographic) trust indicators for those changes. With this understanding, we develop technologies that embed economic incentives that have immediate value to the adopting party and also have second order system-wide security properties. In this talk I begin with the definition of the problem as economic, describe empirical work in macro-economics of security, and close with the description of an example solution called Bongo.' About the speaker: Jean Camp is a Professor at the School of Informatics and Computing at Indiana University.

Aniket Kate, Differential Guarantees for Cryptographic Systems Jan 11, 2017

Differential privacy aims at learning information about the population as a whole, while protecting the privacy of each individual. With its quantifiable privacy and utility guarantees, differential privacy is becoming standard in the field of privacy-preserving data analysis. On the other hand, most cryptographic systems for their privacy properties rely on a stronger notion of indistinguishability, where an adversary should not be able to (non-negligibly) distinguish between two scenarios. Nevertheless, there exists some cryptographic system scenarios for which the notion of indistinguishability is known to be impossible to achieve. It is natural to ask if one can define differential privacy-motivated privacy notions to accurately quantify the privacy loss in those scenarios. In this talk, we will study two such scenarios.Our first scenario will consider (non-)uniform randomness employed in cryptographic primitives. It is well-known that indistinguishability-based definitions of cryptographic primitives are impossible to realize in systems where parties only have access to non-extractable sources of randomness. I will demonstrate that it is, nevertheless, possible to quantify this secrecy (or privacy) loss due to some non-extractable sources (such as the Santha-Vazirani sources) using a generalization of indistinguishability inspired by differential privacy.Our second scenario will capture privacy properties of anonymous communication networks (e.g., Tor). In particular, I will present our AnoA framework that relies on a novel relaxation of differential privacy to enables a unified quantitative analysis of properties such as sender anonymity, sender unlinkability, and relationship anonymity.

Yinqian Zhang, When Side Channel Meets Row Hammer: Cache-Memory Attacks in Clouds and Mobile Devices Dec 07, 2016

Processor caches and memory chips are hardware components used by all software programs on a computer system. They are designed, and thereafter fine-tuned over the years, for better performance and power efficiency, but not for strong isolation between mutually distrustful software programs. However, modern computing paradigm has been shifting towards resource sharing without full trust: In multi-tenant public clouds, virtual machines controlled by different customers are scheduled to run on the same cloud servers; in mobile devices, untrusted third-party apps, though isolated using sandboxes, share the same devices with sensitive apps. Our research question is whether sharing of memory resources will introduce new security threats to these systems.In this talk, we highlight a type of security threats that we call cache-memory attacks. These attacks are possible due to insufficient isolation in hardware memory resources (e.g., various levels of caches, memory controllers, buses and chips, etc.) that are shared between malevolent and sensitive software programs. We coin cache-memory attacks as the umbrella terms of side-channel attacks (i.e., confidentiality attacks), row-hammer attacks (i.e., integrity attacks) and resource contention attacks (i.e., availability attacks). We will discuss the root vulnerabilities of these attacks and their exploitation in the context of clouds and mobile devices. We will also cover some defense techniques against these attacks that we have developed over the past few years. About the speaker: Dr. Yinqian Zhang is an assistant professor of the Department of Computer Science and Engineering at The Ohio State University. His research topics range over various fields in security, including cloud and mobile security, hardware-assisted security, user authentication and anonymous communication. He is known for his work in side-channel attacks and defenses in multi-tenant cloud computing.

Sanjai Narain, A Science of Cyber Infrastructure Configuration Nov 09, 2016

Configuration is the glue for logically integrating cyber infrastructure components to satisfy end-to-end requirements on security and functionality. Every component has a finite number of configuration variables that are set to definite values. It is well-documented that configuration errors are responsible for 50%-80% of infrastructure vulnerabilities and downtime and it can take months to set up and adapt infrastructure. This is because the large conceptual gap between requirement and configuration is manually bridged. This talk presents a Science of Configuration to automatically bridge this gap. The Science is embodied in the Distributed Assured and Dynamic Configuration (DADC) suite of tools for requirement specification, configuration synthesis, repair, vendor-specific adaptation, visualization, emulation, verification, distributed configuration, in-band configuration, reconfiguration planning and moving-target defense. DADC leverages modern SMT solvers that can solve a million constraints in a million variables in seconds, and group communication protocols that provide total-ordering message delivery guarantees. We will sketch a new application of DADC to cloud configuration. About the speaker: Dr. Sanjai Narain is a Fellow and Chief Scientist in the Systems and Cyber Security Department at Vencore Labs. Currently, he leads a Science of Configuration project to increase the efficiency and accuracy of building cyber infrastructure by several orders of magnitude. His industrial expertise is in networking and security, and formal training in mathematical logic, programming languages, and electrical engineering. He studied logic with Professor Alonzo Church at UCLA and Professor J.A. Robinson at Syracuse.

Jeremiah Blocki, Usable and Secure Human Authentication Oct 19, 2016

A typical computer user today manages passwords for many different online accounts. Users struggle with this task ---often forgetting their passwords or adopting insecure practices, such as using the same passwords for multiple accounts and selecting weak passwords. Before we can design good password management schemes it is necessary to address a fundamental question: How can we quantify the usability or security of a password management scheme? In this talk we will introduce quantitative usability and security models. Notably, our user model, which is based on research on human memory about spaced rehearsal, allows us to analyze the usability of a large family of password management schemes while experimentally validating only the common user model underlying all of them. We argue that these quantitative models can guide the development of usable and secure password management schemes. In support of our argument we present Shared Cues, a simple password management scheme in which the user can generate many strong passwords after memorizing a few randomly generated stories. Our password management schemes are precisely specified and publishable: the security proofs hold even if the adversary knows the scheme and has extensive background knowledge about the user (hobbies, birthdate, etc.).This talk is based on joint work with Manuel Blum and Anupam Datta References:http://arxiv.org/abs/1302.5122http://arxiv.org/pdf/1410.1490v1.pdf About the speaker: At a high level Professor Blocki describes himself as "a theoretical computer scientist who is interested in applying fundamental ideas from computer science to address practical problems in usable privacy and security." He is especially interested in developing usable authentication protocols for humans. Are there easy ways for humans to create and remember multiple strong passwords? Can we design secure cryptographic protocols that are so simple that can be run by a human? Jeremiah has also developed algorithms for conducting privacy preserving data analysis in several different application settings including social networks and password data. Prior to joining Purdue Jeremiah completed his PhD on Usable Human Authentication at Carnegie Mellon University under the supervision of his advisors Manuel Blum and Anupam Datta. He also spent a year at Microsoft Research New England as a postdoc.

Terry Ching-Hsiang Hsu, Enforcing Least Privilege Memory Views for Multithreaded Applications Oct 12, 2016

Failing to properly isolate components in the same address space has resulted in a substantial amount of vulnerabilities. Enforcing the least privilege principle for memory accesses can selectively isolate software components to restrict attack surface and prevent unintended cross-component memory corruption. However, the boundaries and interactions between software components are hard to reason about and existing approaches have failed to stop attackers from exploiting vulnerabilities caused by poor isolation. We present the secure memory views (SMV) model: a practical and efficient model for secure and selective memory isolation in monolithic multithreaded applications. SMV is a third generation privilege separation technique that offers explicit access control of memory and allows concurrent threads within the same process to partially share or fully isolate their memory space in a controlled and parallel manner following application requirements. An evaluation of our prototype in the Linux kernel (TCB < 1,800 LOC) shows negligible runtime performance overhead in real-world applications including Cherokee web server (< 0.69%), Apache httpd web server (< 0.93%), and Mozilla Firefox web browser (< 1.89%) with at most 12 LOC changes. About the speaker: Terry Hsu is a PhD candidate at Purdue University studying memory systems and system security. His research is concerned with the development of operating systems. Particular topics of interest include memory model, memory safety, memory isolation, and operating system security

Nicholas Reuhs, The role of cyber insurance in security and risk management Sep 28, 2016

Cyber-liability insurance has grown from a niche product into a multi-billion-dollar market in less than a decade. It has also become a negotiating point in technology-related contracts and a buzzword for corporate boards. In this seminar, we will discuss how this new insurance market has developed -- surveying the spectrum of "cyber" insurance products and outlining what events these products are (and are not) intended to cover. We will also discuss underwriting problems (information asymmetry, correlated losses, etc.) and how these underwriting problems are causing insurers to increasingly dictate security practices and behavior. Finally, we will discuss the future of cyber-liability insurance and how a major event could shift the market's focus or even lead to government intervention. About the speaker: Nick Reuhs is a partner in Ice Miller's Litigation Group, where he concentrates his practice on insurance coverage disputes, risk management and commercial litigation. Nick regularly advises clients in insurance coverage matters, managing claims and advocating policy construction that maximizes insurance recovery. Nick also provides policyholders with counseling on pre-loss issues, ranging from assessments of coverage for particular risks to help with securing favorable coverage terms under specialty insurance policies.

Over the last seven years we have been observing a tremendous growth of crypto-currencies such as Bitcoin and IOU credit networks such as Ripple. Their decentralized and pseudonymous nature, ability to perform transactions across the globe in a matter of seconds, and potential to monetize everything regardless of jurisdiction have been pivotal to their success so far. Despite some major hiccups, their market capitalization is increasing steadily over the years. It is now believed that, in the form of the blockchain technology and the internet of value, these concepts are here to stay.In this talk, I will first present some of our recent and ongoing efforts to improve the privacy of these inherently distributed systems. I will define the concept of peer-to-peer mixing, present an efficient P2P mixing protocol, and instantiate it in Bitcoin and Ripple. In the latter half of the talk, I will present an innovation application for these payment systems. In particular, I will present a novel Bitcoin-based smart contact for non-disclosure agreement (NDA) among mutually distrusting partners that monetarily penalizes malicious disclosures of the confidential documents.

Srivatsan Ravi, Towards Safe In-memory Transactions Aug 31, 2016

Current general-purpose CPUs are multicores, offering multiple computing units within a single chip. The performance of programs on these architectures, however, does not necessarily increase proportionally with the number of cores. Designing concurrent programs to exploit these multicores emphasizes the need for achieving efficient synchronization among threads of computation. When there are several threads that conflict on the same data, the threads will need to coordinate their actions for ensuring correct program behaviour. Traditional techniques for synchronization are based on locking that provides threads with exclusive access to shared data. Coarse-grained locking typically forces threads to access large amounts of data sequentially and, thus, does not fully exploit hardware concurrency. Program-specific fine-grained locking or non-blocking (i.e., not using locks) synchronization, on the other hand, is a dark art to most programmers and trusted to the wisdom of a few computing experts. Thus, it is appealing to seek a middle ground between these two extremes: a synchronization mechanism that relieves the programmer of the overhead of reasoning about data conflicts that may arise from concurrent operations without severely limiting the program's performance. The Transactional Memory (TM) abstraction is proposed as such a mechanism: it intends to combine an easy-to-use programming interface with an efficient utilization of the concurrent-computing abilities provided by multicore architectures. TM allows the programmer to speculatively execute sequences of shared-memory operations as atomic transactions with all-or-nothing semantics: the transaction can either commit, in which case it appears as executed sequentially, or abort, in which case its update operations do not take effect. Thus, the programmer can design software having only sequential semantics in mind and let TM take care, at run-time, of resolving the conflicts in concurrent executions. It is important that the intermediate state witnessed by each transaction be "safe"; if it is not consistent with any sequential execution, then the application may experience a fatal irrecoverable error or enter an infinite loop. In this talk, we focus on implementing safe TM implementations and the inherent complexities associated with them. About the speaker: Srivatsan Ravi is a Postdoctoral researcher/Visiting assistant professor at Purdue University. His research interests are in the theory and practice of distributed computing.

Christopher N. Gutierrez, ErsatzPasswords - Ending Password Cracking Apr 27, 2016

In this work we present a simple, yet effective and practical, scheme to improve the security of stored password hashes, rendering their cracking detectable and insuperable at the same time. We utilize a machine-dependent function, such as a physically unclonable function (PUF) or a hardware security module (HSM) at the authentication server to prevent off-site password discovery as well as a deception mechanism to alert administrators of such attempts. Our scheme can be easily integrated with legacy systems without the need for any additional servers, changing the structure of the hashed password file or any client modifications. When using the scheme the structure of the hashed passwords file, etc/shadow or etc/master.passwd, will appear no different than in the traditional scheme. However, when an attacker exfiltrates the hashed passwords file and tries to crack it, the only passwords she will get are the ErsatzPasswords— the "fake passwords". When an attempt to login using these ErsatzPasswords is detected an alarm is triggered. Even with an adversary who knows about the scheme, cracking cannot be launched without physical access to the authentication server. The scheme also includes a secure backup mechanism in the event of a failure of the hardware dependent function. ErsatzPassword is flexible by design, enabling the proposed scheme to be integrated to existing authentication systems without changes to user experience. The proposed scheme is integrated into the pam_unix module as well as two client/server authentication schemes: LDAP authentication and the Pythia PRF Service [Everspaugh et al. 2015]. The core library to support ErsatzPassword in C and Python required 255 and 103 lines of code, respectively. The integration of ErsatzPassword for each explored authentication systems required less than 100 lines of code. Experimental evaluation of ErsatzPassword shows an increase of authentication latency in the order of 100 ms, which may be acceptable for end user experience. A framework for implementing ErsatzPassword using the Trusted Platform Module (TPM) provides a greater sense of machine-dependent functionality to resist offline attacks.

Pedro Moreno Sanchez, Privacy-preserving payments in credit networks Apr 13, 2016

A credit network models trust between agents in a distributed environment and enables payments between arbitrary pairs of agents. With their flexible design and robustness against intrusion, credit networks form the basis of several Sybil-tolerant social networks, spam-resistant communication protocols, and payment systems.In the first half of the talk, we introduce the concept of credit network and its application in the currently deployed Ripple payment system. We further characterize the privacy issues in Ripple as the result of clustering heuristics to group wallets based on observations on the publicly available Ripple network graph. In the second half of the talk, we show PrivPay, the first provably secure privacy-preserving payment protocol for credit networks. The distinguishing feature of PrivPay is the computation of the maximal credit between two agents without revealing any information about the credit network, the transaction or the agents themselves. Finally, we present our results on privacy-preserving payments on a distributed credit network, where each agent locally stores its own financial information. About the speaker: Pedro Moreno-Sanchez is a PhD student in the Department of Computer Science at Purdue University. His advisor is Prof. Aniket Kate. His current research focuses on the areas of security, privacy and reliability of credit network based systems such as Ripple.

Endadul Hoque, Finding Specification Noncompliance and Attacks in Wireless Network Protocol Implementations Apr 06, 2016

Several newly emerged wireless technologies (e.g., Internet-of-Things)---extensively backed by the tech industry---are being widely adopted and have resulted in a proliferation of diverse smart appliances and gadgets (e.g., smart thermostat, wearables, smartphones), which has ensuingly shaped our modern digital life. These technologies utilize several communication protocols that usually have stringent requirements stated in their specifications or standards, which their implementations are expected to comply with. Noncompliance exhibited by an implementation can cause interoperability issues, inconsistent behavior, or even security vulnerabilities.Automatically detecting whether a protocol implementation is noncompliant with a given property is a long-standing and challenging problem. Moreover, lack of robustness in a protocol implementation to malicious attacks---exploiting subtle vulnerabilities in the implementation---mounted by the compromised nodes in an adversarial environment can limit the practical utility of the implementation by impairing the performance of the protocol and can even have detrimental effects on the availability of the network.Given the stake associated with these wireless technologies, the requirement to ensure secure and reliable operations of the protocol implementations calls for pre-deployment measures. In this talk, I will focus on fortifying these emerging technologies along two dimensions. I will first present an automated framework that enables a developer to check whether a protocol implementation violates its desired properties derived from its specifications and standards.Finally, I will present an automated adversarial testing platform to help developers find malicious attacks that impair the performance of their protocol implementations. About the speaker: Endadul Hoque is a Postdoctoral Research Associate at Northeastern University working with Prof. Cristina Nita-Rotaru and a visiting scholar at Purdue University. He received his PhD in computer science from Purdue University in 2015. His research interests include reliability and security of network protocols and distributed systems. In particular, his approach involves building efficient techniques to automate compliance checking and testing of network protocol implementations and distributed systems in the presence of failures and/or malicious attacks. During his PhD, he was awarded the Graduate Teaching Fellowship in 2014 and the Bilsland Dissertation Fellowship in 2015 to support his dissertation work.

Chris Kanich, Bottom Line Security: Understanding the True Cost of Cybersecurity Attacks Mar 30, 2016

Using the Internet is a risky venture: cybercriminals could be lurking behind any email or in any web page, just waiting to compromise your machine. Practicing and researching cybersecurity is about minimizing that risk. Unfortunately, modern cybercriminals don't compromise machines just because they can - they do it to make money or steal data. Likewise, the risks that end users care about aren't measured in vulnerabilities discovered or hosts compromised, they care about losing hard earned money, embarrassing pictures, or simply a night of their free time because they had to remove malware from the family computer. Cybersecurity research should minimize the chance of successful attacks by maximizing the number of vulnerabilities patched or infiltrations thwarted. However, these technical goals are fundamentally intermediate goals: the ultimate goal of cybersecurity is to minimize the amount of harm that comes to users, which is a quantity denominated in dollars lost, days spent recovering from attacks, or data lost to attackers. By quantifying the harm of these attacks in these meaningful quantities, we can focus defenses and mitigations on the attacks that cause the most harm to the Internet's users.This presentation will highlight recent results that improve our understanding the true cost of cybercrime. I'll also show how these results can lead to actionable insights into which attacks we should be spending our finite effort combating. I'll cover losses due to affiliate fraud, measured in profits lost, both by the platforms and legitimate marketers. I'll also cover losses incurred due to typosquatting: while typosquatting is perpetrated by thousands upon thousands of domains, the harm caused is not clear. We use a model which quantifies how many visitors legitimate sites lose and how much time end users waste when they visit these sites. Finally, I'll showcase a tool which quantifies the value of a user's private data (their account logins), which can motivate better security behavior through a personalized warning regarding how much their account might be worth to cybercriminals. About the speaker: Chris Kanich is an Assistant Professor in the Department of Computer Science at the University of Illinois at Chicago. He received his Ph.D. in Computer Science and Engineering at UC San Diego and a B.S. in Mathematics and Computer Science at Purdue University. His current research focuses on improving user experience in the face of cybersecurity attacks. His approach uses myriad data-driven techniques (anything from botnet infiltration to user studies) to improve our understanding of how to counteract the true motivations of cybercriminals and minimize real-world losses for targets of cybercrime.

Kent Seamons, Usable Secure Webmail for Grassroots Adoption Mar 23, 2016

Recent concerns about government surveillance have focused attention on secure communication tools for the masses. The security properties of these tools receive more attention than their usability properties. This talk will cover our recent effort to design a usable secure webmail system. We have conducted a number of studies to analyze existing tools and our own systems to determine whether these tools are usable by the masses to communicate securely. Most recently, to determine whether secure email is ready for grassroots adoption, we conducted a laboratory user study that recruits pairs of novice users to install and use several of the latest systems to exchange secure messages. We will discuss both quantitative and qualitative results from 25 pairs of novice users as they use Pwm, Tutanota, and Virtru. Participants report being more at ease with this type of study and better able to cope with mistakes since both participants are "on the same page". We find that users prefer integrated solutions over depot-based solutions, and that tutorials are important in helping first-time users. Hiding the details of how a secure email system provides security can lead to a lack of trust in the system. Participants expressed a desire to use secure email, but few wanted to use it regularly and most were unsure of when they might use it. About the speaker: Dr. Kent Seamons is the Director of the Internet Security Research Lab in the Computer Science Department at BYU. His research interests are in usable security, privacy, authentication, identity management, and trust management. He received a PhD in Computer Science from Illinois. Prior to joining the faculty at BYU, he conducted research at the IBM Pittsburgh Lab where he was a co-inventor of trust negotiation. He has published over 50 peer-reviewed papers that have been cited over 4,300 times. Dr. Seamons has been awarded nearly $5 million in funding from NSF, DARPA, NASA, and industry. He is also a co-inventor on four patents in the areas of automated trust negotiation, single sign-on, and security overlays.

Ryan Henry, Batch Techniques for Practical Private Information Retrieval Mar 09, 2016

Private information retrieval (PIR) is a way for clients to query a remote database without the database holder learning the clients' query terms or the responses they generate. Compelling applications for PIR abound in the cryptographic and privacy research literature, yet existing PIR techniques are notoriously inefficient. Consequently, no such PIR-based application to date has seen real-world at-scale deployment.In this talk, I will discuss some ongoing research that unifies "batch query" and "batch coding" techniques to help address PIR's efficiency problem. The new approach exploits the connection between 'ramp secret sharing schemes' and multi-server, information-theoretically secure PIR (IT-PIR) protocols, thereby enabling clients to fetch several records from an IT-PIR database for only *a fraction* the cost of fetching *a single record* using the standard approach. The approach is highly tuneable, and I will briefly discuss interesting asymptotic phenomenon that arise with extremal settings of the various tuning knobs. About the speaker: Ryan Henry is an assistant professor at Indiana University Bloomington. He obtained his PhD from the University of Waterloo in 2014, where he held the Vanier Canada Graduate Scholarship, Canada's most prestigious graduate scholarship. His research explores the systems challenges of applied cryptography, with a particular emphasis on using cryptography to build secure systems that protect the privacy of their users.

Anupam Joshi, Context Aware, Policy based approaches to Security Mar 02, 2016

Traditional approaches to securing systems tend to be fixed and mostly non adaptive. The Policy that defines the security posture is in some sense "hardcoded". In this talk, we focus on approaches to securing systems using approaches that have declarative policies that factor in dynamically evolving context. The approach is grounded in W3C standard representation formats for knowledge and formal logic. We show instances of this approach in two different network settings -- mobile devices and intrusion detection. About the speaker: Anupam Joshi is the Oros Family Professor and Chair of Computer Science and Electrical Engineering Department at the University of Maryland, Baltimore County(UMBC). He is the Director of the UMBC Center for Cybersecurity, and the Co-Technical Director of the newly announced National Cybersecurity FFRDC. He is a Fellow of IEEE.Dr. Joshi obtained a B.Tech degree from IIT Delhi in 1989, and a Masters and Ph.D. from Purdue University in 1991 and 1993 respectively. His research interests are in the broad area of networked computing and intelligent systems. His primary focus has been on data management and security/privacy in mobile/pervasive computing environments, and policy driven approaches to security and privacy. He is also interested in Semantic Web and Data/Text/Web Analytics, especially their applications to (cyber) security. He has published over 200 technical papers with an h-index of 70 and over 17000 citations (per Google scholar), filed and been granted several patents, and has obtained research support from National Science Foundation (NSF), NASA, Defense Advanced Research Projects Agency (DARPA), US Dept of Defense (DoD), NIST, IBM, Microsoft, Qualcom, Northrop Grumman, and Lockheed Martin amongst others.

Xukai Zou, Resilient, privacy-preserving, revocable and user-centric authentication – Biometric Capsule Feb 24, 2016

User authentication and identity management are the first-gate defense and access protection for cyber systems. Authentication failures, including post-authentication attacks, have caused constant system breaches and resulted in serious economic and social consequences to governments, enterprises, and individuals. Passwords or smartcards have issues related to true identity, loss/theft, interoperability, cross-system password vulnerability, and post-authentication attacks. It is frustrating to memorize passwords and painful when one cannot log into a system because of forgetting the password. Due to biometrics' memorization-free, identity-binding and loss-resistant properties, assisted with widely-deployed built-in biometric sensors in mobile devices, biometric authentication is becoming more feasible and very attractive. However, biometrics technology introduces its own challenges. One serious problem is that biometric templates are hard to replace once compromised. In addition, biometrics may disclose a user's sensitive information (e.g., race, gender, even health condition), thus creating user privacy concerns. A demo at Black Hat USA 2015 has alerted the public: fingerprints stored on smartphones can be stolen--remotely and at a large scale. The lost biometrics cannot be revoked and the individual's biometric identity becomes permanently void. A most recent event ``iPhone Error 53" has shocked the real world, and both angered and worried end customers: the iPhones of thousands of iPhone 6 users were killed after their iPhones' touch ID home buttons were repaired (by any third party), which was caused by touch IDs' irrevocability due to the physical binding of fingerprint touch ID with the home button.In this talk, we will present a new biometric authentication method --Biometric Capsule which can address the aforementioned issues. Unlike existing biometric authentication methods, Bio-Capsule (BC) is a template derived from the secure fusion of a user's biometrics and that of a Reference Subject (RS). The RS is simply a physical object, e.g., a doll, or an artificial one, e.g., an image. Theoretical analysis and experiments have shown that the BC mechanism is solid and efficient. BC is replaceable, non-invertible (thus, preserving privacy), and resilient. About the speaker: Dr. Xukai Zou is a faculty member of CERIAS and an associate professor at the Department of Computer and Information Sciences, Indiana University-Purdue University Indianapolis. His current research focus is Applied Cryptography, Network Security, Authentication, secure electronic voting and health and genomic data security and privacy. His research has been supported by NSF, the Department of Veterans Affairs and Industry such as Cisco and Northrop Grumman.

Bruno Ribeiro, Predicting What Users Will do Next Feb 17, 2016

Which song will Smith listen to next? Which restaurant will Alice go to tomorrow? Which product will John click next? These applications have in common the prediction of user trajectories that are in a constant state of flux but subject to hidden constraints (e.g. geographical location, the links of a website). What users are doing now may be unrelated to what they will be doing in an hour from now. In this talk I introduce the difficulties associated with predicting user trajectories, more specifically how the concepts of non-stationary, transiency, and time-heterogeneity make this task challenging. Mindful of these difficulties I introduce Tribeflow, a general method that can perform next product recommendation, next song recommendation, next location prediction, and general arbitrary-length user trajectory prediction without domain-specific knowledge. Extensive simulations on large and small datasets show TribeFlow to be more accurate and up to 413x faster than top state-of-the-art competitors.

Hemanta Maji, Robust Secure Computation Feb 03, 2016

Modern Cryptography provides algorithmic solutions to securely compute over the private data of mutually distrustful parties. These solutions require algorithmic or physical building blocks such as computational hardness assumptions, trusted hardware, correlated private randomness and noisy channels. A fundamental limitation of these solutions is that their security necessarily hinges on the assumption that these underlying building blocks are free of any imperfection. Over the last decade, however, this assumption has been repeatedly proven false in the real world, often rendering these solutions completely insecure. This raises the following important question: "Can secure computation be based on imperfect building blocks?" My research provides algorithmic solutions that resolve this question in the affirmative. About the speaker: Hemanta K. Maji joined the Department of Computer Science at Purdue University as Assistant Professor in Fall 2015. Earlier, he was a post-doctoral researcher and a Center Fellow at the Center of Encrypted Functionalities in University of California, Los Angeles.

Elisa Bertino, Big Data Security and Privacy Jan 27, 2016

Technological advances and novel applications, such as sensors, cyber-physical systems, smart mobile devices, cloud systems, data analytics, and social networks, are making possible to capture, and to quickly process and analyze huge amounts of data from which to extract information critical for security-related tasks. In the area of cyber security, such tasks include user authentication, access control, anomaly detection, user monitoring, and protection from insider threat. By analyzing and integrating data collected on the Internet and Web one can identify connections and relationships among individuals that may in turn help with homeland protection. By collecting and mining data concerning user travels and disease outbreaks one can predict disease spreading across geographical areas. And those are just a few examples; there are certainly many other domains where data technologies can play a major role in enhancing security. The use of data for security tasks is however raising major privacy concerns. Collected data, even if anonymized by removing identifiers such as names or social security numbers, when linked with other data may lead to re-identify the individuals to which specific data items are related to. Also, as organizations, such as governmental agencies, often need to collaborate on security tasks, data sets are exchanged across different organizations, resulting in these data sets being available to many different parties. Apart from the use of data for analytics, security tasks such as authentication and access control may require detailed information about users. An example is multi-factor authentication that may require, in addition to a password or a certificate, user biometrics. Recently proposed continuous authentication techniques extend access control system. This information if misused or stolen can lead to privacy breaches.It would then seem that in order to achieve security we must give up privacy. However this may not be necessarily the case. Recent advances in cryptography are making possible to work on encrypted data – for example for performing analytics on encrypted data. However much more needs to be done as the specific data privacy techniques to use heavily depend on the specific use of data and the security tasks at hand. Also current techniques are not still able to meet the efficiency requirement for use with big data sets.In this talk we will discuss methods and techniques to make this reconciliation possible and identify research directions. About the speaker: Elisa Bertino is professor of computer science at Purdue University and serves as Research Director of the Center for Information and Research in Information Assurance and Security (CERIAS).

Chris Clifton, Privacy in Big Data: Thinking Outside the Anonymity/Confidentiality Box Jan 20, 2016

The computer science community has had a growing research focus in Privacy over the last decade. Much of this has really focused on confidentiality: Anonymization, computing on encrypted data, access control policy, etc. This talk will look at a variety of research results in this area, including "weaker" approaches than the absolutes typically considered in the security community, and how they all come down to the same basic concept of providing confidentiality.Privacy is much more complex. People are often willing to allow use of their data – but not just for anything. This talk will look at such other privacy issues, such as harm to individuals and society from the fear of disclosure or misuse of private data. The talk will conclude with ideas for new research directions in privacy. About the speaker: Dr. Clifton works on data privacy, particularly with respect to analysis of private data. This includes privacy-preserving data mining, data de-identification and anonymization, and limits on identifying individuals from data mining models. He also works more broadly in data mining, including data mining of text and data mining techniques applied to interoperation of heterogeneous information sources. Fundamental data mining challenges posed by these applications include extracting knowledge from noisy data, identifying knowledge in highly skewed data (few examples of "interesting" behavior), and limits on learning. He also works on database support for widely distributed and autonomously controlled information, particularly issues related to data privacy.Prior to joining Purdue, Dr. Clifton was a principal scientist in the Information Technology Division at the MITRE Corporation. Before joining MITRE in 1995, he was an assistant professor of computer science at Northwestern University.

Jim Gallagher, Microsemi Security Solutions and Threat Driven Security Jan 13, 2016

Threat-driven security is a systematic system-level approach that is driven by a clear understanding of the security need – it is not arbitrary application of security technologies based on their perceived effectiveness or hype. Using this systematic approach, the strength of a protection is easily gauged through simple identification of the weakest link in the design. This presentation will review our approach to identifying security vulnerabilities, determining viable mitigations, and developing a threat tree that leads to a robust threat-driven protection. About the speaker: Jim joined Microsemi as Vice President of Engineering for Security Solutions in August 2009. Jim leads the development of software, firmware, crypto, and security products and services to prevent reverse engineering and product tampering. Jim has nearly 30 years of experience in real-time embedded software and system development, with a strong focus on software process implementation. Prior to joining Microsemi, Jim began his career with General Motors holding numerous software and systems assignments. Jim holds a Bachelor of Science degree in Electrical Engineering from the University of Notre Dame and a Master of Software Engineering degree from Carnegie Mellon University.

Aniket Kate, Preventing or Penalizing Equivocation in Decentralized Environments Dec 09, 2015

Making conflicting statements to others, or equivocation, is a simple yet remarkably powerful tool of malicious participants in distributed systems of all kinds. In distributed computing protocols, equivocation leads to Byzantine faults and fairness issues. In this talk, I will cover my recent work towards preventing or penalizing equivocations in decentralized Systems.In the first half of the talk, we study how the resilience of asynchronous distributed computing tasks such as Byzantine agreement and multiparty computation can be improved using an increment-only counter that implements non-equivocation, a mechanism to restrict a corrupted party from making conflicting statements to different (honest) parties. In the second half of the talk, we show how equivocation can be monetarily disincentivized by the use of crypto-currencies such as Bitcoin. To this end, we have designed completely decentralized non-equivocation (smart) contracts, which make it possible to penalize an equivocating party by the loss of its money. About the speaker: Prof. Aniket Kate is an assistant Professor in the the computer science department at Purdue university. He is an applied cryptographer and a privacy researcher. His research projects aim at bridging the large gap between cryptographic research, and systems security and privacy research.Before joining Purdue in 2015, Prof. Kate was a junior faculty member and an independent research group leader at Saarland University in Germany, where he was heading the Cryptographic Systems Research Group.

Laura Amo, Gender Gaps in Cybersecurity Engagement and Self-Efficacy Growth Trajectories Dec 02, 2015

Females are significantly less likely to pursue tech-focused careers, and have significantly lower self-efficacy in technical domains. Despite initiatives to increase female participation in STEM majors, the percentage of females pursuing college degrees in computer and information science actually decreased between 2004 and 2012 in the United States. Towards the ultimate goal of increasing female representation in the cyber workforce, it is important to spark and nurture females' engagement and self-efficacy during formative years in middle and high school. As a first step, we need to define and measure cybersecurity engagement and self-efficacy. In this talk, I will discuss my work in the area of cybersecurity engagement and self-efficacy measurement by introducing the Cybersecurity Engagement and Self-Efficacy Scale. I present results from a pilot study of 34 participants (ages 13 – 17) that tracked growth in cybersecurity engagement and self-efficacy across three time points. Overall, females initially demonstrated significantly lower cybersecurity engagement and self-efficacy relative to males. However, over the course of five days of hands-on learning and simulated cyber-attack, female participants demonstrated significantly greater growth over time and the gender-based gaps in cybersecurity engagement and self-efficacy disappeared. This suggests that informal, activity-based learning experiences are crucial for reducing gender-based gaps in cyber-related domains and may serve as a starting point for promoting female participation, pursuit, and persistence in applied cybersecurity. About the speaker: Laura earned her Ph.D. in Educational Psychology and Quantitative Methods from the University at Buffalo in 2015. She is a visiting assistant professor with the UB School of Management in Management Science and Systems where she teaches large classes in statistics and analytics. Her research in cybersecurity focuses on measuring engagement and self-efficacy, as well as exploring gender differences in growth in these areas. Laura is also currently exploring the role of information-seeking self-efficacy in reducing the education gap in eHealth behaviors, and exploring the role of policy and psychological factors associated with misuse of information systems.

Jongho Won, A Secure Communication Protocol for Drones and Smart Objects Nov 18, 2015

In many envisioned drone-based applications, drones will communicate with many different smart objects, such as sensors and embedded devices. Securing such communications requires an effective and efficient encryption key establishment protocol. However, the design of such a protocol must take into account constrained resources of smart objects and the mobility of drones. In this paper, a secure communication protocol between drones and smart objects is presented. To support the required security functions, such as authenticated key agreement, non-repudiation, and user revocation, we propose an efficient Certificateless Signcryption Tag Key Encapsulation Mechanism (eCLSC-TKEM). eCLSC-TKEM reduces the time required to establish a shared key between a drone and a smart object by minimizing the computational overhead at the smart object. Also, our protocol improves drone's efficiency by utilizing dual channels which allows many smart objects to concurrently execute eCLSC-TKEM. We evaluate our protocol on commercially available devices, namely AR.Drone2.0 and TelosB, by using a parking management testbed. Our experimental results show that our protocol is much more efficient than other protocols. About the speaker: Jongho Won is a PhD student and his advisor is Prof. Bertino. His research interests include the fields of information security, privacy and wireless networks. His current research interests are as follows: key management and secure data collection protocol in wireless sensor networks (WSNs), trustworthiness assessment in WSNs, secure localization of sensors in WSNs, privacy-preserving data aggregation protocol for smart metering and path planning for drones.

Ariel Feldman, Verifying Computations with (Private) State Nov 11, 2015

Is it possible for Alice to compute a result and for Bob to be convinced of its correctness without having to reexecute the computation? What if the computation is performed over sensitive data that Bob is not allowed to see due to privacy concerns? Recent work on proof-based verifiable computation has brought these goals much closer to practicality. In this talk, I will present two implemented systems that incorporate verifiable computation in order to build realistic applications. The first, Pantry, enables a user to outsource a general-purpose computation to a potentially faulty cloud provider and yet verify that the computation was performed correctly. Unlike prior efforts, Pantry allows verifiable computations to operate on remotely-stored data, opening the way to a wide variety of uses such as MapReduce jobs and database queries.The second system, VerDP, aims to resolve the conflict in many research studies between the verifiability of the results and the privacy of the study participants. VerDP accepts queries over sensitive data that are written in a domain-specific language and processes them only if a) it can certify that the result will not compromise individuals' privacy, and if b) it can prove the integrity of the result to the public. Experimental evaluation shows that VerDP can successfully process several types of useful queries, and that the cost of generating and verifying the proofs is practical. About the speaker: Ariel Feldman is an Assistant Professor of Computer Science at the University of Chicago. His research lies at the intersection of computer security and distributed systems. He is presently focused on finding new ways to protect the security and privacy of users of "cloud hosted" services. His interests also include software and network security, data privacy, anonymity, and electronic voting, as well as the interaction between computer security, law, and public policy. Previously, he was a postdoctoral researcher at the CIS department at the University of Pennsylvania, and he received his Ph.D. in Computer Science from Princeton University in 2012.

Balamurugan Anandan, Secure Multiparty Computation and Differential Privacy Nov 04, 2015

Secure multiparty computation (MPC) and differential privacy are two notions of privacy that deal respectively with how and what functions can be privately computed. In this talk, I will first give an overview of MPC and differential privacy. Then, I will show how to build a two party differentially private secure protocol in the presence of semi-honest and malicious adversaries.Computing a differentially private function using secure function evaluation prevents private information leakage both in the process, and from information present in the function output. However, the very secrecy provided by secure function evaluation poses new challenges if any of the parties are malicious. We then relax the utility requirement of computational differential privacy to reduce computational cost, still giving security with rational adversaries. Finally, we provide a modified two-party computational differential privacy definition and show correctness and security guarantees in the rational setting. About the speaker: Balamurugan Anandan is a PhD candidate in Computer Science from Purdue University and works with Prof. Chris Clifton. He received his bachelor's degree in computer science from Kongu Engineering College, India in 2005 and MS in computer science from Purdue University in 2013. His research interests is in the intersection of data mining and privacy, specifically focussing on developing privacy preserving protocols.

Koray Mancuhan, Anonymized Data Oct 21, 2015

Privacy has been a hot issue since early 2000s, in particular with the rise of social network and data outsourcing. Data privacy is a big concern in data outsourcing because it involves sharing personal data with third parties. In this talk, I will give an introduction to data privacy on topics such as privacy standards, data anonymization techniques, and data anonymization usage in data outsourcing and data mining. Then, I will present our work in data mining using anonymized data. We propose a data publisher-third party decision tree learning method for outsourced private data. The privacy model is anatomization/fragmentation: the third party sees data values, but the link between sensitive and identifying information is encrypted with a key known only to data publisher. Data publishers have limited processing and storage capability. Both sensitive and identifying information thus are stored on the third parties. The approach presented also retains most processing at the third parties, and data publisher-side processing is amortized over predictions made by the data publishers. Experiments on various datasets show that the method produces decision trees approaching the accuracy of a non-private decision tree, while substantially reducing the data publisher's computing resource requirements. About the speaker: Koray is a PhD student in the Department of Computer Science at Purdue University. He is currently a member of the privacy preserving data mining lab under the supervision of Chris Clifton. His research elaborates the data mining models from the anonymized data. The challenge in his research is the injected uncertainty into data because of anonymization methods. In most cases, uncertainty slows down the data mining models and require special mechanisms to exploit noisy data. His work includes learning algorithms such as k-NN classification, SVM classification, decision tree classification and frequent itemset mining.Koray received his masters degree in Computer Science from Purdue University and his undergraduate degree in Computer Engineering from Galatasaray University. Throughout his masters degree, he studied on data mining and social fairness, and authored papers in this topic. Before joining to Purdue CS, he did his research in semantic web area. He was a former member of Complex Networks lab in Galatasaray University where he worked in developing a new automatic web service annotation tool.

Fang-Yu Rao, A Hybrid Private Record Linkage Scheme: Separating Differentially Private Synopses FromMatching Records Oct 14, 2015

Private record linkage protocols allow multiple parties to exchange matching records, which refer to the same entities or have similar values, while keeping the non-matching ones secret. Conventional protocols are based on computationally expensive cryptographic primitives and therefore do not scale. To address these scalability issues, hybrid protocols have been recently proposed that combine differential privacy techniques with secure multiparty computation techniques. However, a drawback of such protocols is that they disclose to the parties both the matching records and the differentially private synopses of the datasets involved in the linkage. Consequently, differential privacy is no longer always satisfied. To address this issue, we propose a novel framework, which separates the private synopses from the matching records. The two parties do not access the synopses directly, but still use them to efficiently link records. We theoretically prove the security of our framework. In addition, we have developed a simple but effective strategy for releasing private synopses. Extensive experimental results show that our framework is superior to the existing methods in terms of both recall rate and efficiency. About the speaker: Fang-Yu Rao is a Ph.D. candidate in Computer Science at Purdue University. He received his Master and Bachelor of Computer Science and Engineering from National Sun Yat-sen University. His research interests are in data privacy, information security, and applied cryptography, with an emphasis on privacy-preserving data analytics.

Omar Chowdhury, Applying Formal Verification Techniques for Checking Compliance of Computer Systems and Protocols Sep 30, 2015

While designing computer systems and their underlying protocols, architects impose functionality, security, and privacy requirements or policies with which the designed systems and protocols should comply with. These requirements and policies are generally written in natural language and more often than not they are not complied with in the implementations due to ambiguity, misinterpretation of the requirements, or developer errors. Non-compliance with the requirements can not only have security, privacy, and utility consequences but also can have safety implications. One possible solution is to express the requirements in some formal language. In addition to eliminating ambiguities and misinterpretations of the requirements, this also enables application of formal verification techniques to check for compliance of the implementation against the desired requirements or the policies. Formal verification techniques can be applied for checking compliance in potentially three different settings. In the first setting,compliance checking is performed statically before a system or a protocol is deployed. In the second setting, a runtime monitor can be deployed alongside the system or the protocol, and the monitor provably disallows the system or the protocol to take non-compliant actions. Finally, compliance can be be checked in a post-hoc fashion by capturing all the relevant runtime events in an audit log which can then be scrutinized for non-compliance. In this talk, I will present demonstrative examples of using formal verification techniques for compliance checking in each of these settings. About the speaker: Omar Chowdhury is a Post-Doctoral Research Associate at the Department of Computer Science at Purdue University. Before joining Purdue, he was a Post-doctoral Research Associate at Cylab, Carnegie Mellon University. He received his Ph.D. in Computer Science from the University of Texas at San Antonio.

Kexin Pei, LEAPS: Detecting Camouflaged Attacks with Statistical Learning Guided by Program Analysis Sep 23, 2015

Currently cyberinfrastructures are facing increasinglystealthy attacks that implant malicious payloads under thecover of benign programs. Existing attack detection approachesbased on statistical learning methods may generate misleadingdecision boundaries when processing noisy data with such amixture of benign and malicious behaviors. On the other hand,attack detection based on formal program analysis may lackcompleteness or adaptivity when modeling attack behaviors.In light of these limitations, we have developed LEAPS, anattack detection system based on supervised statistical learningto classify benign and malicious system events. Furthermore,we leverage control flow graphs inferred from the system eventlogs to enable automatic pruning of the training data, whichleads to a more accurate classification model when applied tothe testing data. Our extensive evaluation shows that, comparedwith pure statistical learning models, LEAPS achieves consistentlyhigher accuracy when detecting real-world camouflaged attackswith benign program cover-up. About the speaker: Kexin Pei is a second year master student at Department of Computer Science, Purdue University.

John Feddema, Evaluation of Urban Vehicle Tracking Algorithms Sep 16, 2015

Low signal-to-noise data processing algorithms forimproved detection, tracking, discrimination and situationalthreat assessment are a key research challenge. As sensortechnologies progress, the number of pixels will increase significantly.This will result in increased resolution, which couldimprove object discrimination, but unfortunately, will also resultin a significant increase in the number of potential targets totrack. Many tracking techniques, like multi-hypothesis trackers,suffer from a combinatorial explosion as the number ofpotential targets increase. As the resolution increases, the phenomenologyapplied towards detection algorithms also changes.For low resolution sensors, blob tracking is the norm. Forhigher resolution data, additional information may be employedin the detection and classification steps. The most challengingscenarios are those where the targets cannot be fully resolved,yet must be tracked and distinguished for neighboring closelyspaced objects. Tracking vehicles in an urban environment is anexample of such a challenging scenario. This report evaluatesseveral potential tracking algorithms for large-scale tracking inan urban environment. The algorithms considered are: randomsample consensus (RANSAC), Markov chain Monte Carlo dataassociation (MCMCDA), tracklet inference from factor graphs,and a proximity tracker. Each algorithm was tested on acombination of real and simulated data and evaluated againsta common set of metrics.

Yonghwi Kwon, P2C: Understanding Output Data Files via On-the-Fly Transformation from Producer to Consumer Executions Sep 09, 2015

In cyber-attack analysis, it is often highly desirable to understand the meaning of an unknown file or network message in the absence of their consumer (i.e. the program that parses and understands the file/message). For example, a malware may stealthily collect information from a victim machine, store them as a file and later send it to a remote server. P2C is a novel technique that can parse and understand unknown files and network messages. Given a file/message that was generated in the past without the presence of any monitoring techniques, and a set of potential producers of the file/message, P2C systematically explores the execution paths in the producers without requiring any inputs. In the meantime, it tries to transform a producer execution to a consumer execution that closely resembles the ideal consumer execution that can parse the given unknown file/message. In particular, when a write operation is encountered in the original execution, P2C performs the opposite read operation on the unknown file/message and patches the original execution with the loaded value. In order to handle correlations between data fields in the file/message, P2C follows a trial-and-error approach to look for the correct transformation until the file/message can be parsed and the meaning of their fields can be disclosed. Our experiments on a set of real world applications demonstrate P2C is highly effective. About the speaker: Yonghwi Kwon is a PhD student in the Department of Computer Science at Purdue University. His research interests include, but not limited to, dynamic/static binary analysis, reverse-engineering, and system security, focusing on solving security and debugging problems using dynamic binary analysis and translation techniques. He is a recipient of the SIGSOFT Distinguished Paper Award and Best Paper Award from ASE 2013.

Jianjun Huang, SUPOR: Precise and Scalable Sensitive User Input Detection for Mobile Apps Sep 02, 2015

While smartphones and mobile apps have been an essential part of our lives, privacy is a serious concern. Previous mobile privacy related research efforts have largely focused on predefined known sources managed by smartphones. Sensitive user inputs through UI (User Interface), another information source that may contain a lot of sensitive information, have been mostly neglected. This talk examines the possibility of scalably detecting sensitive user inputs from mobile apps. In particular, SUPOR, a novel static analysis tool that automatically examines the UIs to identify sensitive user inputs containing critical user data, such as user credentials, finance, and medical data, is designed and implemented. SUPOR enables existing privacy analysis approaches to be applied on sensitive user inputs as well. To demonstrate the usefulness of SUPOR, we build a system that detects privacy disclosures of sensitive user inputs by combining SUPOR with off-the-shelf static taint analysis. We apply the system to 16,000 popular Android apps, and conduct a measurement study on the privacy disclosures. SUPOR achieves an average precision of 97.3% and an average recall of 97.3% for sensitive user input identification. SUPOR finds 355 apps with privacy disclosures and the false positive rate is 8.7%. We discover interesting cases related to national ID, username/password, credit card and health information. About the speaker: Jianjun Huang is a PhD student in the Department of Computer Science at Purdue University, supervised by Prof. Xiangyu Zhang. Jianjun Huang is interested at leveraging program analysis techniques to detect malicious behaviors and flaw in mobiles apps. In particular, his research combines static program analysis, text and GUI analysis.More details may be found at https://www.cs.purdue.edu/homes/huang427/.

Samuel Jero, Leveraging State Information for Automated Attack Discovery in Transport Protocol Implementations Aug 26, 2015

Network transport protocols, like TCP, underlie the vast majority of Internet communication, from email to web browsing to instant messaging to file transfer. Despite their importance, these protocols are difficult to implement correctly, leading to a long string of bugs and vulnerabilities dating back to 1985.In this talk we present a new method for finding attacks in unmodified transport protocol implementations using the specification of the protocol state machine to reduce the search space of possible attacks. Such reduction is obtained by applying malicious actions to all packets of the same type observed in the same state instead of applying them to individual packets. Our method requires knowledge of the packet formats and protocol state machine. We demonstrate our approach by developing SNAKE, a tool that automatically finds performance and resource exhaustion attacks on unmodified transport protocol implementations. SNAKE utilizes virtualization to run unmodified implementations in their intended environments and network emulation to create the network topology. SNAKE was able to find 9 attacks on 2 transport protocols, 5 of which we believe to be unknown in the literature. This work was awarded best paper in DSN 2015. About the speaker: Samuel Jero is a PhD student in the Department of Computer Science at Purdue University working with Prof. Cristina Nita-Rotaru.

He received a combined BS and MS in Computer Science from Ohio University in 2013.

Steve Bellovin, Lawful Hacking: Using Existing Vulnerabilities for Wiretapping on the Internet Apr 29, 2015

For years, legal wiretapping was straightforward: the officer doing the intercept connected a tape recorder or the like to a single pair of wires. By the 1990s, though, the changing structure of telecommunications — there was no longer just "Ma Bell" to talk to — and new technologies such as ISDN and cellular telephony made executing a wiretap more complicated for law enforcement. Simple technologies would no longer suffice. In response, Congress passed the Communications Assistance for Law Enforcement Act (CALEA), which mandated a standardized lawful intercept interface on all local phone switches. Technology has continued to progress, and in the face of new forms of communication — Skype, voice chat during multi-player online games, many forms of instant messaging, etc.— law enforcement is again experiencing problems. The FBI has called this "Going Dark": their loss of access to suspects' communication. According to news reports, they want changes to the wiretap laws to require a CALEA -like interface in Internet software.CALEA , though, has its own issues: it is complex software specifically intended to create a security hole — eavesdropping capability — in the already-complex environment of a phone switch. It has unfortunately made wiretapping easier for everyone, not just law enforcement. Congress failed to heed experts' warnings of the danger posed by this mandated vulnerability, but time has proven the experts right. The so-called "Athens Affair", where someone used the built-in lawful intercept mechanism to listen to the cell phone calls of high Greek officials, including the Prime Minister, is but one example. In an earlier work, we showed why extending CALEA to the Internet would create very serious problems, including the security problems it has visited on the phone system.This talk explores the viability and implications of an alternative method for addressing law enforcement's need to access communications: legalized hacking of target devices through existing vulnerabilities in end-user software and platforms. About the speaker: Steven M. Bellovin is the Percy K. and Vidal L. W.

Kui Ren, Breaking Mobile Social Networks for Automated User Location Tracking Apr 01, 2015

Location-based social networks (LBSNs) feature location-based friend discovery services attracting hundreds of millions of active users world-wide. While leading LBSN providers claim the well-protection of their users' location privacy, in this talk we show for the first time through real world attacks that these claims do not hold after summarizing the existing practices from the industry. In our identified attacks, a malicious individual with the capability of no more than a regular LBSN user can easily break most LBSNs by manipulating location information fed to LBSN client apps and running them as location oracles. I will further talk about the development of an automated user location tracking system based on the proposed attack and its test on leading LBSNs including Wechat, Skout, and Momo. Real-world experiments on 30 volunteers and the defense approaches will also be discussed. These findings serve as a critical security reminder of the current LBSNs pertaining to a vast number of users.

Xinming Ou, Aiding Security Analytics -- From Dempster-Shafer Theory to Anthropology Mar 04, 2015

Research on new technologies to help security analysts defend networks and systems from attacks has unique challenges --- the ad-hoc nature of attacks and their mitigation makes formal modeling elusive; the diverse threat scenarios of organizations makes a one-size-fit-all solution unlikely; and the lack of data and production deployment to test research prototypes makes evaluation extremely difficult. In this talk I will describe the unique approaches we have been taking to address this problem. Since algorithms and tools that arise from this research are intended to help the tasks performed by human analysts, it becomes a pre-requisite for researchers to first understand how analysts do their jobs, and identify the key obstacles and bottlenecks for performance. I will explain how we designed/built the SnIPS system for intrusion analysis by eliciting expert knowledge through ad-hoc interviews, and the formulation of a customized Dempster-Shafer theory to capture how humans deal with the inherent uncertainty in this reasoning process. I then explain how this led us to eventually adopt an anthropological approach to address this research challenge.Anthropology is a social science well known for its long-term participant observation method in which researchers spend substantial amounts of time living/working together with the subjects of study, as participant observers who take part in the daily lives and challenges of those they study, giving them a more empathic perspective understanding of their views, practices, and challenges. I will use the examples in my past eight years' research to explain why this type of ethnographic fieldwork is crucial and could be a very effective method to extract the "tacit knowledge" embodied in the practices of security analysts. Joining the "community of practice" of security operations will enable researchers to access the tacit knowledge, make it explicit, subject it to systematic analysis and modeling, and yield algorithms that execute the knowledge in an automated fashion. I will also talk about "unexpected findings" we are still deriving from on-going anthropological fieldwork at multiple security operations centers. About the speaker: Dr. Xinming (Simon) Ou is an associate professor of Computer Science and the Peggy and Gary Edwards Chair in Engineering at Kansas State University. He received his PhD from Princeton University in 2005.

Kami Vaniea, Software updates: decisions and security implications Feb 25, 2015

Installing security-relevant software updates is one of the best computer protection mechanisms available to end users. Unfortunately, users frequently decide not to install future updates, regardless of whether they are important for security, after negative experiences with past updates. This means that even non-security updates (such as user interface changes) can impact the decisions users make about installing future security updates. As many as 70% of computers worldwide are running old versions of Java, a common target of attack. In this presentation I will talk about my research into why users choose to not update their software, and what can be done about it. I report on a multi-factor study where we investigated why users choose to not update software. We interviewed users and analysed the logs on their computers. We found that the default automatic update behaviour of Windows did not always match users' intentions, sometimes causing users to be more secure than they intended, sometimes less. Non-security components of updates, such as user interface changes, also impacted users' willingness to update software. About the speaker: Dr. Kami Vaniea is an Assistant Professor at Indiana University's School of Informatics and Computing. She obtained her PhD in Computer Science from Carnegie Mellon University where she was a member of the Cylab Usable Privacy and Security group working in the areas of computer security and human computer interaction. Her research interests are in how people manage access to digital items and information. Her work examines how people interact with security technologies, and explores how to best design security technologies that support users and improve security.

Ninghui Li, Privacy Notions for Data Publishing and Analysis Feb 18, 2015

Data collected by organizations and agencies are a key resource intoday's information age. The use of sophisticated data mining techniquesmakes it possible to extract relevant knowledge that can then be used for avariety of purposes, such as research, developing innovative technologiesand services, intelligence and counterterrorism operations, and providinginputs to public policy making. However the disclosure of those data posesserious threats to individual privacy. In this talk, we will present the evolvement of privacy notions fordata publishing and analysis, leading to our proposed membership privacyframework, which formalizes the intuition that privacy means that theadversary cannot significantly increasing its ability to conclude that anentity is in the input dataset. We show that several recently proposedprivacy notions, including differential privacy, are instantiations of themembership privacy framework, and that the framework provides a principledapproach to developing new privacy notions under which better utility can beachieved than what is possible under differential privacy. About the speaker: Ninghui Li is a Professor of Computer Science at Purdue University. Hisresearch interests are insecurity and privacy. Prof. Li is currently Vice Chair of ACM SpecialInterest Group on Security, Audit and Control (SIGSAC) and Program Chair of 2015 ACM Conference on Computer andCommunications Security (CCS).

Mathias Payer, Code-Pointer Integrity Feb 11, 2015

Programs are full of bugs, leading to vulnerabilities. We'll discusspower and limitations of code-pointer integrity (CPI), a strong butpractical security policy that enforces memory safety for all codepointers, protecting against any form of control-flow hijack attack(e. g., ROP or JOP).Systems code is often written in low-level languages like C/C++, whichoffer many benefits but also delegate memory management toprogrammers. This invites memory safety bugs that attackers canexploit to divert control flow and compromise the system. Deployeddefence mechanisms (e. g., ASLR, DEP) are incomplete, and strongerdefence mechanisms (e. g., CFI) often have high overhead and limitedguarantees (and are therefore not generally deployed).In this talk we discuss code-pointer integrity (CPI), a strongsecurity policy that guarantees the integrity of all code pointers ina program (e.g., function pointers, saved return addresses) andthereby prevents all control-flow hijack attacks, includingreturn-oriented programming and jump-oriented programming. We alsointroduce code-pointer separation (CPS), a relaxation of CPI withbetter performance properties. Both CPI and CPS offer substantiallybetter security-to-overhead ratios than the state of the art, they arepractical (we protect a complete FreeBSD system and over 100 packageslike apache and postgresql), effective (prevent all attacks in theRIPE benchmark), and efficient, resulting in very low to negligibleperformance overhead. About the speaker: Mathias Payer is a security researcher and an assistant professor incomputer science at Purdue university. His interests are related tosystem security, binary exploitation, user-space software-based faultisolation, binary translation/recompilation, and (application)virtualization. His research focuses on protecting applications evenin the presence of vulnerabilities, with a focus on memory corruption.

Omar Chowdhury, Regulatory Compliance Checking Over Encrypted Audit Logs Feb 04, 2015

Individuals have the privacy expectation that organizations (e.g., bank, hospital) that collect personal information from them will not share these personal information with mischievous parties. To prevent unauthorized disclosure of personal information by organizations, US federal government has put forward privacy legislation like HIPAA and GLBA. Violation of these privacy regulations can bring down heavy financial penalties for the organization. To maintain compliance with all the relevant privacy regulations, organizations collect day-to-day privacy events in an audit log which is periodically checked for compliance. The audit logs capturing the privacy sensitive events tend to be large and due to the cost-effectiveness of cloud infrastructures, outsourcing the audit log storage to a third party cloud service provider is now a viable option for organizations. As the audit logs can possibly contain customers' sensitive personal information, protecting confidentiality of the audit log data from the cloud service provider and other malicious parties should be a major objective for the organization. One possibility is to encrypt the audit logs before uploading it in the cloud storage. However, encrypting the audit log with any semantically secure encryption scheme might prohibit the organization from automatically check compliance of the audit log. Theoretical solutions like fully homomorphic encryption is not practically viable in this scenario. In this talk, I will present two very simple audit log encryption schemes that reveal enough information so that the organization can run an automatic compliance checking algorithm over the encrypted log. With empirical evaluation we demonstrate that, our enhanced compliance checking algorithm incurs low to moderate overheads for our cryptographic schemes, relative to a baseline without encryption.

Savvas Savvides, Practical Confidentiality Preserving Big Data Analysis in Untrusted Clouds Jan 28, 2015

The "pay-as-you-go" cloud computing model has strong potential for efficiently supporting big data analysis jobs expressed via data-flow languages such as Pig Latin. Due to security concerns — in particular leakage of data — government and enterprise institutions are however reluctant to moving data and corresponding computations to public clouds. In this talk we will discuss Crypsis, a system that allows execution of MapReduce-style data analysis jobs directly on encrypted data. Crypsis transforms data analysis scripts written in Pig Latin so that they can be executed on encrypted data. Crypsis to that end employs existing practical partially homomorphic encryption (PHE) schemes, and adopts a global perspective in that it can perform partial computations on the client side when PHE alone would fail. About the speaker: Savvas Savvides is a PhD student in Computer Science at Purdue University. He earned his Master's degree in Computer Science from New York University and his Bachelor's in Computer Science from the University of Manchester. His primary research interests include Information Security, Distributed Systems and Cloud Computing. His current research focus is on devising practical solutions for confidentiality preserving big data analysis jobs.

Bharath Samanthula, Security with Privacy - A Research Agenda Jan 21, 2015

Cloud computing is a key technology for storing, managing and analyzing big data. However, such large, complex, and growing data, typically collected from various data sources, such as sensors and social media, can often contain personally identifiable information (PII) and thus the organization collecting the big data may want to protect their outsourced data from the cloud. In this talk, we will discuss current research towards development of efficient and effective privacy-enhancing (PE) techniques for management and analysis of big data in cloud computing. In particular, we will discuss initial approaches to address two important PE applications: (i) privacy-preserving data management and (ii) privacy-preserving data analysis under the cloud environment. Additionally, we will discuss research issues that still need to be addressed to develop comprehensive solutions to the problem of effective and efficient privacy-preserving use of data. About the speaker: Bharath Kumar Samanthula is a Postdoctoral Research Associate in the Cyber Center department and a Visiting Assistant Professor in the Department of Computer Science at Purdue University. His primary research interests include Personal Privacy, Information Security, Applied Cryptography, and Data Mining. His current research focus is on devising privacy-enhanced solutions for various data outsourcing tasks in Cloud Computing and Social Networks.

Kevin Bowers, You can hack, but you can't hide: Using log analysis to detect APTs Nov 12, 2014

In my talk I will be describing new techniques developed at RSA Labs to analyze massive log data commonly collected by large enterprises to detect and identify suspicious activity. Unlike common signature-based detection mechanisms used today, our approach leverages behavior patterns that persist across different infection vectors, and is thus more resilient to attacker evasion. Moreover, our techniques are unique in their ability to detect stealthy campaigns in which only a single host sporadically communicates with malicious sites controlled by attackers. Through effective data reduction and algorithms inspired from the graph-theoretic belief propagation model we identify the most suspicious domains contacted by hosts in an organization in different stages of an APT campaign (e.g., initial delivery, infection, command-and-control, etc.). We demonstrate the effectiveness of our techniques against two datasets. The first, a public dataset made available by Los Alamos National Laboratory includes the simulations of APT campaigns overlaid on their DNS traffic. We successfully detect 94% of the campaigns with only a 1% false positive rate. We then apply the techniques to 38TB of web proxy logs collected by a large enterprise to discover hundreds of malicious domains that had bypassed other installed security tools. About the speaker: Kevin Bowers is a Senior Research Scientist and Manager of RSA Laboratories, the security research group at RSA, the Security Division of EMC. He holds a B.S. in Electrical, Computer and Systems Engineering and Computer Science, and a B.S. in Mathematics, both from Rensselaer Polytechnic Institute, as well as an M.S. in Computer Science from Carnegie Mellon University.

Barrett Caldwell and Omar Eldardiry, Improving Analyst Team Performance and Capability in NOC / SOC Operations Centers Nov 05, 2014

Network Operations Center and Security Operations Center (NOC / SOC) teams have complex and challenging cognitive tasks that are crucial to the IT health of the organization, but existing tools and metrics do not support this range of tasks. To enhance their key tasks, namely situation awareness, incident response, prevention and knowledge sharing, it is critical to understand how people, tools and information sharing co-function in a NOC environment, and what limits their performance--from low-level analysts to their managers and team leads responsible for translating this NOC/SOC value to others in the organization. Beginning at RSA 2014, our research team began to explore how to improve the information available and displayed to NOC / SOC analysts, team leads, and managers. Our interviews and information display usability efforts are focused on recognizing and reducing the gaps that limit NOC/SOC effectiveness and integration with the rest of the organization. The two recurring themes that address the needs of lower- and higher-level analysts, and their managers were: 1) Analysts need to effectively turn data visualizations into usable presentations to increase network situation awareness, and 2) SOC leads and managers need tools and metrics to effectively communicate the status of the organization's network assets, team operations and company's incident response preparedness to the rest of the organization. Besides standard training, analysts are required to engage in the development of expertise and acquiring skills necessary to perform required tasks. Transfer of organizational knowledge to novice analysts efficiently is a vital process to maximize the organization's capabilities at all times. In preliminary interviews, network managers and team leads stated that they are unaware of tools that will allow them to document work procedures and cases to be used as a resource for novice analysts. They express frustration from the need of their continuous involvement in operational level tasks that interrupt their managerial tasks. About the speaker: Barrett S.

Golden G. Richard III, "Memory Analysis, Meet GPU Malware" Oct 22, 2014

Graphics Processing Units (GPUs) have evolved from very specialized,idiosyncratic hardware intended to execute specialized graphics workloadsto semi-autonomous "supercomputers" that can be programmed easily usingcommon programming languages and powerful, portable APIs. GPUs also formthe basis for an emerging threat, GPU malware, which offloads importantaspects of malicious computations onto the GPU. The benefits of executingmalicious computations on the GPU include abundant compute power, a largeamount of semi-non-volatile memory, and perhaps most importantly, isolationfrom host-based security measures. While memory analysis offers powerfultools to detect and analyze traditional host-based malware, there areessentially no equivalent tools for analyzing GPU malware. Furthermore,existing general-purpose tools for debugging GPU applications arecompletely ineffective if a large number of conditions are not establishedbefore a GPU application is executed, all of which will certainly beviolated by weaponized GPU malware. This talk explores GPU malware indetail, identifies why it's hard to analyze, and also discusses measuresthat can easily employed to make analysis even more difficult. A primarymotivation for this research is the 2015 DFRWS Digital Forensics Challenge,under development by Dr. Richard, the aim of which is to increase interestin GPU malware analysis and foster the development of powerful tools toanalyze and combat this threat.

Larry Ponemon, Responsible Information Management and the 2014 Cost of Data Breach: Global Analysis Oct 01, 2014

Throughout the world, companies are finding that data breaches have become as common as a cold but far more expensive to treat. With the exception of Germany, companies had to spend more on their investigations, notification and response when their sensitive and confidential information was lost or stolen. As revealed in the 2014 Cost of Data Breach Study: Global Analysis, sponsored by IBM, the average cost to a company was $3.5 million in US dollars and 15 percent more than what it cost last year. Will these costs continue to escalate? Are there preventive measures and controls that will make a company more resilient and effective in reducing the costs? Nine years of research about data breaches has made us smarter about solutions. Critical to controlling costs is keeping customers from leaving. The research reveals that reputation and the loss of customer loyalty does the most damage to the bottom line. In the aftermath of a breach, companies find they must spend heavily to regain their brand image and acquire new customers. Our report also shows that certain industries, such as pharmaceutical companies, financial services and healthcare, experience a high customer turnover. In the aftermath of a data breach, these companies need to be especially focused on the concerns of their customers. As a preventive measure, companies should consider having an incident response and crisis management plan in place. Efficient response to the breach and containment of the damage has been shown to reduce the cost of breach significantly. Other measures include having a CISO in charge and involving the company's business continuity management team in dealing with the breach.In most countries, the primary root cause of the data breach is a malicious insider or criminal attack. It is also the most costly. In this year's study, we asked companies represented in this research what worries them most about security incidents, what investments they are making in security and the existence of a security strategy. An interesting finding is the important role cyber insurance can play in not only managing the risk of a data breach but in improving the security posture of the company. While it has been suggested that having insurance encourages companies to slack off on security, our research suggests the opposite. Those companies with good security practices are more likely to purchase insurance. Global companies also are worried about malicious code and sustained probes, which have increased more than other threats. Companies estimate that they will be dealing with an average of 17 malicious codes each month and 12 sustained probes each month. Unauthorized access incidents have mainly stayed the same and companies estimate they will be dealing with an average of 10 such incidents each month. When asked about the level of investment in their organizations' security strategy and mission, on average respondents would like to see it doubled from what they think will be spent—an average of $7 million to what they would like to spend—an average of $14 million. This may be a tough sell in many companies. However, our cost of data breach research can help IT security executives make the case that a strong security posture can result in a financially stronger company.

We applied our research to an enterprise mobile infrastructure, where we utilize a mobile on-device agent named TractorBeam. This agent periodically collects changed storage locations from each device to allow for later image reconstruction and analysis. We collaborated with Purdue University to perform a three-month experiment where we evaluated TractorBeam's operation in a simulated operational setting to identify masquerading users (i.e., users operating the devices other than the enterprise designated mobile device user). We surmised that even if a masquerading user on an enterprise mobile device lacked malicious intent; this masquerader would still be undesirable to the enterprise. On campus, we provided a set of human-subject volunteers the following: preconfigured mobile devices with cellular voice and data plans, also with the TractorBeam agent pre-installed; a simple acceptable use policy; and deceptive project background information to stimulate normal behavior. As a result of the experiment, we collected enough data to successfully reconstruct 821 forensic images, extract over 1 million audit events, and perform masquerading user analysis. This presentation describes PMF and characterizes the collected experiment corpus, the extracted audit events, and the performance of TractorBeam throughout the protocol. Then our approach for advanced masquerading detection will be discussed. About the speaker: Mr. Mark Guido is a principal cyber engineer and researcher at The MITRE Corporation, a non-profit organization chartered to work in the public interest.

Mathias Payer, WarGames in Memory: Fighting Powerful Attackers Sep 10, 2014

Memory corruption (e.g., buffer overflows, random writes, memoryallocation bugs, or uncontrolled format strings) is one of the oldestand most exploited problems in computer science. These problems arehere to stay as low-level languages like C or C++ continue to tradesafety for potential performance. A small set of all proposedsolutions (e.g., Address Space Layout Randomization, Data ExecutionPrevention, and stack canaries) is applied in practice but realexploits show that all currently deployed protections can be defeated.The problems of current protection mechanisms call for novelapproaches towards software protection that fulfill the followingproperties: low overhead for high security guarantees, no changes tothe original source code, and compatibility to existing libraries andbinaries (including a partial migration strategy).We present a security policy that deterministically protects softwareagainst control-flow hijack attacks. Our mechanism uses both auser-space virtualization system (building on binary translation) tosupport legacy code and a compiler-based framework to enforce theintegrity of all code pointers at runtime. Such a system controls theexecution of all code in user-space, extracts information from allloaded components, and enforces a strong security policy for theexecuted software with low overhead. We show possible pitfalls andlimitations and discuss future extensions and optimizations. About the speaker: Mathias Payer is a security researcher and an assistant professor incomputer science at Purdue university. His interests are related tosystem security, binary exploitation, user-space software-based faultisolation, binary translation/recompilation, and (application)virtualization.Before joining Purdue in 2014 he spent two years as PostDoc in DawnSong's BitBlaze group at UC Berkeley. He graduated from ETH with a Dr.sc. ETH in 2012. The topic of his thesis is related to low-levelbinary translation and security. After developing a fast binarytranslation system (fastBT) he started to analyze different exploittechniques and wondered how binary translation could be used to raisethe guard of current systems (with TRuE and libdetox as a prototypeimplementation of the security framework).

Brendan Saltaformaggio, DSCRETE: Automatic Rendering of Forensic Information from Memory Images via Application Logic Reuse Sep 03, 2014

State-of-the-art memory forensics involves signature-based scanning of memory images to uncover data structure instances of interest to investigators. A largely unaddressed challenge is that investigators may not be able to interpret the content of data structure fields, even with a deep understanding of the data structure's syntax and semantics. For example, an investigator may know that a buffer field is holding a photo image, but still cannot display (and hence understand) the image. We call this the data structure content reverse engineering challenge. In this talk, we present DSCRETE, a system that enables automatic interpretation and rendering of in-memory data structure contents. DSCRETE is based on the observation that the application in which a data structure is defined usually contains interpretation and rendering logic to generate human-understandable output for that data structure. Hence DSCRETE aims to identify and reuse such logic in the program's binary and create a "scanner+renderer" tool for scanning and rendering instances of the data structure in a memory image. We will show that DSCRETE is able to recover a variety of application data — e.g., images, figures, screenshots, user accounts, and formatted files and messages — with high accuracy. The raw contents of such data would otherwise be unfathomable to human investigators. About the speaker: Brendan Saltaformaggio is a Ph.D. student in the Department of Computer Science at Purdue University. His research focuses on the application of binary analysis techniques to digital forensics problems. Most recently, his work on data structure content reverse engineering won the Best Student Paper Award at Usenix Security 2014. Brendan earned a BS with Honors in Computer Science from the University of New Orleans. Prior to joining Purdue, Brendan was a digital forensics researcher at MIT Lincoln Labs (2012) and the Greater New Orleans Center for Information Assurance (2011).

Rachel Sitarz, Women In Cyber Security Apr 30, 2014

In our ever connected society, security has become an essential component for all facets of life. Businesses, government, academics, and individually, all facets have a need to protect and secure technology. Over the past 5-10 years, the demand for cyber security professionals has significantly increased. According to the Bureau of Labor Statistics, employment for Cyber Security Specialists is expected to increase much faster than the average career over the course of the next 10 years. Despite the growing demand, women represent an alarmingly low percentage. This can be demonstrated in nearly any university's technology courses. Cyber security especially is highly male-dominated. Research shows that having a balance of male and female perspectives facilitates diverse and creative innovation and problem solving, within the ever changing realm of cyber security.The NSF SFS funded Broadening Participation of Women in Cybersecurity Project, which aims to build a movement towards diversifying Cyber Security. The program put on the Women in Cyber Security Conference (WiCyS), in Nashville, TN, April 11-12. I will discuss my experience at this conference. I will also discuss takeaways from this conference, and important information for anyone interested in pursuing a career in this ever evolving and highly demanded field. About the speaker: Rachel Sitarz is a PhD student in Cyber Forensics at Purdue University. She studies under the guidance of Dr. Marcus Rogers. She obtained her Master degree in Cyber Forensics in 2010 from Purdue University. She received her undergraduate degrees in Law and Society, Psychology and Forensics in 2007 from Purdue University. Over the past three years, while being a full-time student, Rachel worked full-time for the Indiana State Police, as a Criminal Intelligence Analyst, on the Internet Crimes Against Children Task Force. Currently, Rachel works for the IT Security and Policy section at Purdue, where she builds analytical products from the current threats that are seen on the Purdue network. Rachel is also an Adjunct Professor, teaching Research Methods. Rachel's area of research interest is on the psychological and behavioral analysis of cyber criminals. She aims to understand the user behind the crime. How they are behaving, what programs they are using to facilitate their crimes, how do they engage with other criminals, are among many of her areas of study.

Masooda Bashir, Online Privacy Agreements, is it Informed Consent? Apr 16, 2014

Considering that most consumers do not read Privacy Policies and Terms of Service agreements before accepting them, considerable informational asymmetry exists between consumers and cloud service providers regarding the collection and processing of personal information online. One potential method for reducing this informational asymmetry is the application of informed consent to online environments. Informed consent online will mean upholding principles such as disclosure, competence, comprehension, voluntariness, and agreement. Comprehension and voluntariness are arguably the hardest principles to achieve under current Internet business models and consumer behavior patterns. In this talk I will present the results of an extensive, two-part privacy survey that assessed knowledge and opinions concerning comprehension and voluntariness in online consent agreements. Results expose comprehension gaps with respect to the contents of consent agreements as well as the background knowledge that would be necessary to understand the significance of the terms within the documents. In addition, our survey results highlight the coercive nature of the online consent process and suggest ways for better facilitating voluntariness in online interactions. We found substantial support for alternative service delivery models concerning privacy and for legislation that would endorse standardized consent agreements. These findings provide thought-provoking information which can be used to guide future efforts aimed at increasing consumer awareness about online privacy issues. About the speaker: Dr. Masooda Bashir is an Assistant Professor at the Graduate School of Library and Information Science at the University of Illinois at Urbana Champaign. Dr. Bashir also has appointments at the Coordinated Science laboratory, Information Trust Institute, Industrial and Enterprise Engineering and directs the social science research at the college of engineering. Dr. Bashir received her undergraduate degrees in Mathematics and Computer Science and her Ph.D. in Psychology from Purdue University. She worked for several years as a systems analyst, technical trainer, manager, and global manager for a number of high-tech corporations in Silicon Valley, including Lotus and IBM. Most recently, Dr. Bashir was the Assistant Director for Social Trust Initiatives in the Information Trust Institute (ITI) at the University of Illinois at Urbana-Champaign. Dr. Bashir's areas of research interests lie at the interface of IT, Psychology, and Society, especially how privacy, trust, and security factors intersect from a psychological point of view with information technology.

Chris Jenkins, Integrity Levels: A New Paradigm for Protecting Computing Systems Apr 09, 2014

As the field of determined and increasingly sophisticated adversaries multiplies, the confidence in the integrity of deployed computing devices magnifies. Given the ubiquitous connectivity, substantial storage, and accessibility, the increased reliance on computer platforms make them a substantial target for attackers. Over the past decade, malware transitioned from attacking a single program to subverting the OS kernel by means of what is known as a rootkit. While computer systems require patches to fix newly discovered vulnerabilities, undiscovered vulnerabilities potentially remain. Signature-based schemes seek to detect malware with a known signature or digital fingerprint. Signature-less schemes seek to detect anomalies within the computer system by understanding normal behavior. Both architectures are typically built on top of existing solutions or paradigms. Furthermore, these solutions tend to utilize mechanisms that operate within the OS. If the OS becomes compromised, these mechanisms may be vulnerable to deactivation.We propose an approach to designing computer systems that inherently decouples the function of the computer system from its security specification. Instead of preventing and detecting malware attacks by patching code or using signatures (though we can use them as well), our proposed approach focuses on the policy specification of the system and possible graceful degradation of functionality according to the policy as anomalies of security concern are detected. We believe this innovative paradigm uses existing technologies in a novel manner to determine the integrity level of the system. Based on the integrity level, the system may behave differently and/or limit access to data available at a given integrity level. About the speaker: Dr. Chris Jenkins is a senior member of technical staff at Sandia National Laboratories in Albuquerque, NM. His primary responsibility focuses on researching new computing paradigms for mitigating compromise (malware) in current computing systems. He seeks to find ways to move beyond detection and prevention of malware and rootkits. Specifically, he concentrates on how to design systems that operate in a compromised state while maintaining availability and basic functionality. For decades, computer systems have been designed around the OS/app two- domain model. He has proposed a different model that attempts to bridge the old model to a new proposed four-domain model. The current prototype highlights a potential framework for achieving this goal. The current prototype utilizes various technologies ranging from low-level virtualization techniques to computer security policy specification at a high level. Additionally, he taught a mini-course entitled Virtualization on ARM at Sandia. His current career aspiration emphasizes on finding different ways to utilize next-generation processor and platforms to solve current and future cyber-security challenges. Chris received his bachelor's degree in computer engineering from the University of Illinois at Urbana-Champaign. He finished his PhD at the University of Wisconsin-Madison focusing on accelerating cryptographic algorithms utilizing SIMD execution units on a software-defined radio DSP.

Marina Blanton, General-Purpose Secure Computation and Outsourcing Mar 12, 2014

The desire to compute on sensitive data without revealing it has led to several decades of research in the area of secure multi-party computation. Today, cloud computing serves as a major motivation for the development of secure data processing techniques suitable for use in outsourced environments for computing with private or sensitive data. Despite much attention, most of the available techniques focused on a rather narrow domain of integer arithmetic. In this talk, we describe our work on other types of computation and algorithms suitable for secure computation and outsourcing with the goal of enabling secure and efficient distributed implementation of a general-purpose program. This, in particular, includes a compiler that transforms a program written in C extension, where variables to be protected are marked as private, into its secure distributed implementation suitable for execution in the cloud.

Marina Gavrilova, Machine Intelligence for Biometric and On-Line Security Mar 05, 2014

Security research domain has recently witnessed tremendous growth in respect to all aspects of information access and sharing. There has been notable progress in developing successful approaches to tackle the problem of user authentication. Among those approaches, biometric-based authentication firmly established itself as one of the most reliable, efficient, and versatile tools for providing discretionary access control to a secure resource or system. While state-of-the art methods for biometric authentication are becoming increasingly more powerful and better understood, the same unfortunately cannot be said about security of users populating on-line communities or cyberworld. Ensuring safe and secure communication and interaction among users and, respectably, their on-line identities presents unique challenges to academicians, as well as the industry and the public. Despite the fact that those challenges are regularly making headlines in the news, in government reports and in IT security domain, there is a lack of effort to address this urgent problem. The limited efforts that do exists are currently restricted to network security, password protection, encryption, database security and policy-making efforts. However, one of most crucial components for ensuring on-line security ñ the relationship between communication among users and user authentication, has been largely overlooked. This crucial issue requires a systematic study and a targeted effort to develop effective security solutions for cyberworlds, which is the main topic of this proposed talk. About the speaker: Marina L. Gavrilova is an Associate Professor in the Department of Computer Science, University of Calgary. Dr. Gavrilova research interests lie in the area of biometric security, cognitive sciences, pattern recognition, social networking and cyberworlds.

Rahul Potharaju, Delivering "Always-on" Services Despite Flaky Network Infrastructure Feb 26, 2014

As computing shifts to a service-oriented world, a key need is to deliver an always-on experience to the end-users. However, providing a 24x7x365 available service is challenging because failures are the norm rather than an exception in distributed systems. While there has been significant work to improve server and software reliability, networks have become the new "weakest link" in delivering reliable services. Towards improving network service reliability, my research focuses on (a) studying reliability of datacenter networks, (b) building automated systems for problem inference, and (c) gaining operational experience from real-world deployment of the systems I built.In this talk, I will answer three key questions on improving service reliability in datacenters:1. What is the service impact due to network failures? What are their root causes?2. How to build geo-distributed cloud services?3. How do we analyze unstructured data from network operators to improve network management?The outcomes of this work have either undergone a tech-transfer or are being used by multiple business groups inside a large cloud provider. About the speaker: Rahul Potharaju is a PhD candidate in the Computer Science department of Purdue University and a member of CERIAS, advised by Prof. Cristina Nita-Rotaru. Prior to that, in 2009, he earned his Masters Degree in Computer Science from Northwestern University.

Ting-Fang Yen, Beehive: Large-Scale Log Analysis for Detecting Suspicious Activity in Enterprise Networks Feb 12, 2014

As more and more Internet-based attacks arise, organizations are respondingby deploying an assortment of security products that generate situationalintelligence in the form of logs. These logs often contain high volumes ofinteresting and useful information about activities in the network, and areamong the first data sources that information security specialists consultwhen they suspect that an attack has taken place. However, security productsoften come from a patchwork of vendors, and are inconsistently installed andadministered. They generate logs whose formats differ widely and that areoften incomplete, mutually contradictory, and very large in volume. Hence,although this collected information is useful, it is often dirty.We present a novel system, Beehive, that attacks the problem ofautomatically mining and extracting knowledge from the dirty log dataproduced by a wide variety of security products in a large enterprise. Weimprove on signature-based approaches to detecting security incidents andinstead identify suspicious host behaviors that Beehive reports as potentialsecurity incidents. These incidents can then be further analyzed by incidentresponse teams to determine whether a policy violation or attack hasoccurred. We have evaluated Beehive on the log data collected in a largeenterprise, EMC, over a period of two weeks. We compare the incidentsidentified by Beehive against enterprise Security Operations Centerreports, antivirus software alerts, and feedback from enterprise securityspecialists. We show that Beehive is able to identify malicious events andpolicy violations which would otherwise go undetected. About the speaker: Ting-Fang Yen is a research scientist at RSA Laboratories, the security division of EMC. Ting-Fang's research interests include network security and data analysis for security applications. Ting-Fang received a B.S. degree in Computer Science and Information Engineering from National Chiao Tung University, Taiwan, and M.S. and Ph.D. degrees in Electrical and Computer Engineering from Carnegie Mellon University.

Marina Kaljurand, Economic Policy and Cyber Challenges in Estonia Dec 04, 2013

Muhammad Umer Arshad, Trust Management for Publishing Graph Data Nov 20, 2013

Use of graph-structured data models is on the rise -- in graph databases, in representing biological and healthcare data as well as geographical data.In order to secure graph-structured data, and develop cryptographically secure schemes for graph databases, it is essential to formally define and develop suitable collision resistant one-way hashing schemes and show them they are efficient. The widely used Merkle hash technique is not suitable, because graphs may be directed acyclic ones or cyclic ones. In this talk, we will address this problem. In particular, we: (1) discuss the practical and formal security model of hashing schemes for graphs, (2) present the formal security model of perfectly secure hashing schemes, (3) describe constructions of hashing and perfectly secure hashing of graphs, and (4) present performance results for the constructions. We use graph traversal techniques, which are highly efficient for hashing, redaction, and verification of hashes graphs. We have implemented the proposed schemes. Performance analysis on both real and synthetic graph data sets support the viability of our approach. About the speaker: Umer received his MS and BS degrees in ECE from University of Engineering and Technology, Lahore, Pakistan in 2005 and 2002 respectively. Currently he is doctoral student in the School of ECE, Purdue University. His research interests are in the area of distributed systems and information security.

Randall Brooks, Cloud Security: How Does Software Assurance Apply Nov 13, 2013

It was once said that the last time one had full control of their software was right before they released it. This is ever more important as organizations move applications and services into a public cloud to support a mobile lifestyle. Clouds have been described as "a safe and secure private cloud", "a semi-trusted partner cloud", or "a wild wild west full and open public cloud". It's typically toward the latter in which the industry has been moving. Because of this, one must understand their Attack Surface and threat environment to ensure that they have focused on "building security in" to their application. About the speaker: Randall Brooks, Engineering Fellow, Raytheon, has more than 15 years of experience in Cybersecurity with expertise in Software Assurance (SwA) and secure development life cycles (SDLC). He has been awarded three US patents on Intrusion Detection and Prevention, and three US andone UK patent(s) on Cross Domain solutions. He is also a CISSP, CSSLP, ISSEP, ISSAP and an ISSMP.

Ninghui Li, Membership Privacy: A Unifying Framework For Privacy Definitions Oct 30, 2013

Data collected by organizations and agencies are a key resourcein today's information age. The use of sophisticated data mining techniquesmakes it possible to extract relevant knowledge that can then be used for avariety of purposes, such as research, developing innovative technologiesand services, intelligence and counter-terrorism operations, and providinginputs to public policy making. However the disclosure of those data posesserious threats to individual privacy. In this talk, we present a novelprivacy framework that we call Membership Privacy, which prevents theadversary from significantly increasing its ability to conclude that anentity is in the input dataset. Membership privacy is parameterized by afamily of distributions that captures the adversary's prior knowledge. Thepower and flexibility of the proposed framework lies in the ability tochoose different distribution families to instantiate membership privacy.Many privacy notions in the literature are equivalent to membership privacywith interesting distribution families, including differential privacy,differential identifiability, and differential privacy under sampling. Theframework also provides a principled approach to developing new privacynotions under which better utility can be achieved than what is possibleunder differential privacy. This is joint work with Wahbeh Qardaji, DongSu, Yi Wu, and Weining Yang. About the speaker: Ninghui Li is an Associate Professor of Computer Science atPurdue University. He received a Bachelor's degree from the University ofScience and Technology of China in 1993 and a Ph.D. in Computer Science fromNew York University in 2000.

Daniel DeLaurentis, Systems of Systems: Opportunities and Challenges Oct 23, 2013

What are Systems of Systems? Why are we interested in them? What about them vex us? These topics will be addressed in this overview talk along with emphasis on the analysis of vulnerabilities in SoS Architectures. Our particular work targets advancements in the modeling and analysis of System of Systems (SoS), in particular to support systems engineering activities associated with architecture design, evolution, and operational assessment. We analyze dynamic impacts of interdependencies and uncertainties inherent in SoS. We envision an analytic workbench (populated by a variety of analytical tools from several sources) that makes these analysis capabilities accessible to "SoS System Engineers" in tackling real SoS problems like Air Transportation and Ballistic Missile Defense.

Paul Thompson, The Durkheim Project: Privacy Considerations in Predicting Military and Veteran Suicide Risk Sep 25, 2013

The DARPA Detection and Computational Analysis of Psychological Signals (DCAPS) program provided initial funding for the Durkheim Project. While DCAPS as a whole addressed PTSD, the Durkheim Project sought to predict military and veteran suicide risk. We developed a clinician's dashboard, which presents suicide risk predictions for the clinician's patients based on analysis of: a) free text portions of VA medical records and, b) opt-in social media postings. Dartmouth's Committee for the Protection of Human Subjects approved our protocol to conduct a Veterans Affairs (VA) medical records study with the White River Junction, Vermont, VA Medical Center. A second protocol has been approved to study opt-in Facebook postings from active duty military personnel and veterans. We have built the software infrastructure to collect these opt-in postings in collaboration with Facebook. A third protocol is currently being developed to support intervention, when high suicide risk is predicted. This talk will describe the Durkheim Project, focusing on privacy issues related to using opt-in social media postings. About the speaker: Paul Thompson's thesis research was on probabilistic information retrieval. He was an assistant professor at Drexel University's College of Information Studies and then a member of PRC, Inc.'s (now part of Northrop Grumman) artificial intelligence development group, where he conducted research in natural language understanding and information retrieval. He later worked for West Publishing Company (now part of Thomson - Reuters). After joining Dartmouth College's Institute for Security Technology Studies in 2001, he became the technical lead for the Semantic Hacking project. He also participated in an Institute for Information Infrastructure Protection (I3P) research project on control system security in the oil and gas industry. He is currently an instructor in the Department of Genetics at the Geisel School of Medicine at Dartmouth. He was the co-principal investigator on the DARPA Detection and Computational Analysis of Psychological Signals program's Durkheim project.

John Butterworth, BIOS Chronomancy: Using Timing-Based Attestation to Detect Firmware Rootkits Sep 04, 2013

In 2011 the National Institute of Standard and Technology (NIST) released a draft of special publication 800-155. This document provides a more detailed description than the Trusted Platform Module (TPM) PC client specification for content that should be measured in the BIOS to provide an adequate Static Root of Trust for Measurement (SRTM). In this talk we look at the implementation of the SRTM from a Dell Latitude E6400 laptop.I'll discuss a couple ways that an attacker can gain access to the BIOS and demonstrate an exploit we discovered in the BIOS update process that bypasses the signed firmware update and allows an attacker to execute arbitrary code in the context of System Management Mode. This allows an attacker to install a malicious BIOS reflash even in the presence of a signed update requirement.Next I'll show what happens when an attacker is able to do once he gains access to a system BIOS. I'll show how a 51 byte patch to the SRTM can cause it to provide a forged measurement to the TPM indicating that the BIOS is pristine. If a TPM Quote is used to query the boot state of the system, this TPM-signed falsification will then serve as the root of misplaced trust. We also show how reflashing the BIOS may not necessarily remove this trust-subverting malware.To fix the un-trustworthy SRTM we apply the technique of "timing-based attestation" to create a custom SRTM that can detect malicious modifications of itself. We call our timing-based attestation system "BIOS Chronomancy" because the extra trust is divined from timing, and we show that it could be incorporated into vendor BIOSes as a stronger root of trust for measurement. About the speaker: John Butterworth is a security researcher at The MITRE Corporation who specializes in low level system security. Currently he is applying his electrical engineering background and firmware engineering background to investigate UEFI/BIOS security.

Keith Watson, Information Security Challenges in an Academic Environment Aug 28, 2013

The university environment has unique challenges for information security. Just as corporate networks have exploded in size, services, users, and devices, university networks also have a continually changing and diverse user population, an open network that encourages collaboration, intellectual property that has requirements to be shared as well as protected, and budgetary constraints that reduce services or move data outside of the university. This talk will explore some of these issues. About the speaker: Keith Watson is a security architect for IT Security & Policy at Purdue University. Previously, Keith spent ten years at CERIAS as a research engineer.

Jarek Duda, New possibilities of steganography based on Kuznetsov-Tsybakov problem Aug 21, 2013

To hide information within a picture we usually replace the least significant bits. This approach is no longer available if there is only 1 bit/pixel like for Quick Response Codes we meet everyday now. I will talk about theoretical limitation and practical aspects of hiding information in such situations: by generating encoding sequences fulfilling given constraints, for example to enforce resemblance to given picture (grayness of pixel defines probability of using "1" there). If the receiver would know the constraints/picture, we could just use entropy coder for this purpose, but we would like to omit this requirement here. In Kuznetsov-Tsybakov problem only the sender knows simple constraints, but it turns out that we can approach the same channel capacity as if both sides would know them. I will talk about generalizations to statistical constraints and applications for example to picture codes, steganography or lossy compression. About the speaker: Jaroslaw Duda has received MSc in Computer Science, Mathematics and Physics, and PhD in Computer Science and Physics from Jagiellonian University in Cracow, Poland. His main interest is information theory, both directly applied in computer science and as an integral part of different fields of science. He is currently a Postdoctoral Researcher in the Center for Science of Information and the Computer Science Department at Purdue University, USA, working with W. Szpankowski.

David Pisano, Identity-Based Internet Protocol Network Apr 24, 2013

The Identity-Based Internet Protocol (IBIP) Network project is experimenting with a new enterprise oriented network architecture using standard Internet Protocol to encode identity (ID) information into the IP packet by a new edge security device referred to as the IBIP policy enforcement point (PEP). This is a variant of a network admission control process that establishes user and host identities as well as provides optional information on host visibility, organizational affiliation, current role, and trust metric (associated with the user and host endpoints). Our motivation is to increase our security posture by leveraging identity, reducing our threat exposure, enhancing situational understanding of our environment, and simplifying network operations. In addition to authentication, we leverage strong anti-spoofing technology to improve accountability. We reduce our threat surface by "hiding" our client hosts and making all infrastructure devices inaccessible. Any attempt to access a hidden host or infrastructure device results in a policy violation attributable to the user/host that caused the violation and provides enhanced situational awareness of such activities. Our servers can also have a "permissible use" policy that ensures that the server only operates across the network per that policy. Finally, as users log in and servers are added to the network, all dynamic configurations for access control initiated by such changes are automatically carried out without manual intervention, thereby reducing potential vulnerabilities caused by human errors.11.Extracted from "Nakamoto, G.; Durst, R.; Growney, C.; Andresen, J.; Ma, J.; Trivedi, N.; Quang, R.; Pisano, D., "Identity-Based Internet Protocol Networking," MILITARY COMMUNICATIONS CONFERENCE, 2012 - MILCOM 2012 , vol., no., pp.1,6, Oct. 29 2012-Nov. 1 2012.

Rahul Potharaju, Towards Automated Problem Inference from Trouble Tickets Apr 17, 2013

The growing demand for cloud services is driving the need to deliver an always-on and safe user experience in accessing their data and applications. Examples include web search, social networking, email, ecommerce, video streaming, data analytics and even mission-critical services such as power grid control. Such environments are required to be highly available and secure. This is often satisfied by having experts monitoring the system 24x7 to ensure that problems, if any, are resolved within a reasonable time. The need to solve a problem within the minimum time gives rise to a "whatever-it-takes-to-fix-the-problem" attitude amongst experts and produces a constant flow of informal text documenting the debugging steps taken to resolve problems. Understanding the content within this informal text at scale is the key to uncovering big problem trends that will enable us learn from mistakes and improve system design.In this talk, I will present NetSieve, a system that we built that aims to do automated problem inference from trouble tickets. Specifically, I will show you how statistical natural language processing (NLP) can be combined with knowledge representation, ontology modeling and human-guided learning to automatically analyze natural language text in trouble tickets to infer the problem symptoms, troubleshooting activities and resolution actions. I will further discuss fundamental challenges which arise when extracting meaning from such massive open-domain text corpora. Finally, I will then discuss how we applied NetSieve in a massive data center setting to automatically analyze 10K+ network trouble tickets and how we used these results to improve several key network operations. About the speaker: Rahul Potharaju is a PhD student in the Computer Science department of Purdue University and a member of CERIAS, advised by Prof. Cristina Nita-Rotaru. Prior to that, in 2009, he earned his Masters Degree in Computer Science from Northwestern University. He has over two years of industrial research experience working on collaboration projects with Microsoft Research, Redmond and Motorola Applied Research Center. His current work focuses on large-scale Internet measurements, problem inference system, intrusion detection and security aspects of smartphones architectures and reliability aspects of data centers both from a hardware and a software perspective. A recurring theme in all his research is combining cross-domain techniques such as those from natural language processing with statistical machine learning and data mining to make surprising inferences in the networking and smartphone areas.

Aaron Massey, Regulatory Compliance Software Engineering Mar 27, 2013

Laws and regulations safeguard citizens' security and privacy. For example, the Health Insurance Portability and Accountability Act of 1996 (HIPAA) governs the security and privacy of electronic health records (EHR) systems. HIPAA violations can result in millions of dollars in penalties for non-compliance. Ensuring EHR systems are legally compliant is challenging for software engineers because the laws and regulations governing EHR systems are written by policymakers with little to no understanding of software engineering. This presentation introduces the field of Regulatory Compliance Software Engineering and discusses a particular research concern within that field: How can we help software engineers seeking to assess whether security and privacy requirements for EHR systems are legally compliant? About the speaker: Aaron Massey is a Postdoctoral Fellow at Georgia Tech's School of Interactive Computing and the Associate Directory of ThePrivacyPlace.org. His research interests include computer security, privacy, and regulatory compliance software engineering. Aaron earned the MS and PhD degrees in Computer Science from North Carolina State University and a BS in Computer Engineering from Purdue University. He is a recipient of a Google Policy Fellowship and the Walter H. Wilkinson Research Ethics Fellowship. He is a member of the ACM, IEEE, IAPP, and the USACM Public Policy Council.

Kristin Heckman, Active Cyber Network Defense with Denial and Deception Mar 20, 2013

In January 2012, MITRE performed a real-time, red team/blue team cyber-wargame experiment. This presented the opportunity to blend cyber-warfare with traditional mission planning and execution, including denial and deception tradecraft. The cyber-wargame was designed to test a dynamic network defense cyber-security platform being researched in The MITRE Corporation's Innovation Program called Blackjack, and to investigate the utility of using denial and deception to enhance the defense of information in command and control systems. The Blackjack tool failed to deny the adversary access to real information on the command and control mission system. The adversary had compromised a number of credentials without the computer network defenders' knowledge, and thereby observed both the real command and control mission system and the fake command and control mission system. However, traditional denial and deception techniques were effective in denying the adversary access to real information on the real command and control mission system, and instead provided the adversary with access to false information on a fake command and control mission system. About the speaker: Kristin E. Heckman, D.Sc. is a Lead Scientist at The MITRE Corporation with interdisciplinary skills in computer science, cognitive science, neuropsychology, and cognitive neuroscience. She has ten years of experience in applied research, serving as the principal investigator for MITRE Innovation Program research projects or as the project leader for sponsored work across the Intelligence Community. Her research areas include intelligence interviewing, deception detection, subconscious priming, perception, denial and deception in computer security, and the psychophysiological and neurological signatures of emotions, intent, and deception. She has authored several papers, a book chapter, and a book. She has developed and delivered training in these areas for internal MITRE Institute courses, as well as for external courses in sponsor environments. She was an adjunct faculty member of The George Washington University from 2005-2007, teaching Computer Science Senior Design. Dr. Heckman received her Doctorate of Science in Machine Intelligence and Cognition with minors in Neuropsychology and Developmental Psychology from The George Washington University in 2004.

Emiliano DeCristofaro, Whole Genome Sequencing: Innovation Dream or Privacy Nightmare? Mar 06, 2013

Recent advances in DNA sequencing technologies have put ubiquitous availability of whole human genomes within reach. It is no longer hard to imagine the day when everyone will have the means to obtain and store one's own DNA sequence. Widespread and affordable availability of whole genomes immediately opens up important opportunities in a number of health-related fields. In particular, common genomic applications and tests performed in vitro today will soon be conducted computationally, using digitized genomes. New applications will be developed as genome-enabled medicine becomes increasingly preventive and personalized. However, the very same progress also amplifies worrisome privacy concerns, since a genome represents a treasure trove of highly personal and sensitive information.In this talk, we will overview biomedical advances in genomics and discuss associated privacy, ethical, and security challenges. We begin to address genomic privacy by focusing on some important applications: Paternity Tests, Ancestry Testing, Personalized Medicine, and Genetic Compatibility Tests. After carefully analyzing these applications and their privacy requirements, we propose a set of efficient techniques based on private set operations. This allows us to implement, in silico, some operations that are currently performed via in vitro methods, in a secure fashion. Experimental results demonstrate that proposed techniques are both feasible and practical today. Finally, we explore a few alternatives to securely store human genomes and allow authorized parties to run tests in such a way that only the required minimum amount of information is disclosed, and present an Android API framework geared for privacy-preserving genomic testing. About the speaker: Emiliano De Cristofaro is a Research Scientist in the Security and Privacy group at PARC (a Xerox Company). In 2011, he received a PhD in Networked Systems from the University of California, Irvine, advised by Gene Tsudik.

Weining Yang, Minimizing Private Data Disclosures in the Smart Grid Feb 20, 2013

Smart electric meters are meters that can measure electric usage with a pretty high frequency. Smart electric meters pose a substantial threat to the privacy of individuals in their own homes. Combined with a method called non-intrusive load monitors, smart meter data can reveal precise home appliance usage information. An emerging solution to behavior leakage in smart meter measurement data is the use of battery-based load hiding. In this approach, a battery is used to store and supply power to home devices at strategic times to hide appliance loads from smart meters. A few such battery control algorithms have already been studied in the literature.In this talk, we will ﬁrst consider two well known battery privacy algorithms, Best Effort (BE) and Non-Intrusive Load Leveling (NILL), and demonstrate attacks that recover precise load change information, which can be used to recover appliance behavior information, under both algorithms. We will then introduce a stepping approach to battery privacy algorithms that fundamentally differs from previous approaches by maximizing the error between the load demanded by a home and the external load seen by a smart meter. By design, precise load change recovery attacks are impossible. We also propose mutual-information based measurements to evaluate the privacy of different algorithms. We implement and evaluate four novel algorithms using the stepping approach, and show that under the mutual-information metrics they outperform BE and NILL About the speaker: Weining Yang is a PhD student in the Computer Science department of Purdue University. He received his Bachelor's degree in Computer Science and Technology in 2011 from Tsinghua University. His research interests are information security and data privacy.

Rahul Potharaju, I'm not stealing, I'm merely borrowing - Plagiarism in Smartphone App Markets Feb 13, 2013

Plagiarism is the copying of another party's ideas and passing them off as your own. In the world of smartphone app-markets, this is usually followed by confusion for the buyers (users) and lost sales for the original developer. In some cases, these plagiarized applications act as carriers for malware that can steal your bank details or leak your private information to third-parties. While closed markets such as Apple's AppStore and Windows Marketplace mitigate this problem to some extent through their manual application approval process, open markets such as Google's Android Market, where anyone can publish an application for others to download, are plagued by this problem.In this talk, I will show how an attacker can launch malware onto a large number of smartphone users by plagiarizing Android applications and by using elements of social engineering to increase the infection rate. Using a dataset of 158,000 smartphone applications' meta-information, I will portray the seriousness of this problem. To this end, we propose three detection schemes that rely on syntactic fingerprinting to detect plagiarized applications under different levels of obfuscation used by the attacker. Experimental analysis of 7,600 smartphone application binaries shows that the proposed schemes detect all instances of plagiarism from a set of real-world malware incidents with 0.5% false positives and scale to millions of applications using only commodity servers. About the speaker: Rahul Potharaju is a PhD student in the Department of Computer Science at Purdue University and a member of CERIAS.

Chris Gates, Using Probabilistic Generative Models for Ranking Risks of Android Apps Feb 06, 2013

One of Android's main defense mechanisms against malicious apps is a risk communication mechanism which, before a user installs an app, warns the user about the permissions the app requires, trusting that the user will make the right decision. This approach has been shown to be ineffective as it presents the risk information of each app in a "stand-alone" fashion and in a way that requires too much technical knowledge and time to distill useful information.We introduce the notion of risk scoring and risk ranking for Android apps, to improve risk communication for Android apps, and identify three desiderata for an effective risk scoring scheme. We propose to use probabilistic generative models for risk scoring schemes, and identify several such models, ranging from the simple Naive Bayes, to advanced hierarchical mixture models. Experimental results conducted using real-world datasets show that probabilistic generative models significantly outperform existing approaches, and that Naive Bayes models give a promising risk scoring approach. About the speaker: Christopher Gates is a PhD student in the Computer Science department of Purdue University and a member of CERIAS. He received his Masters Degree in Computer Science in 2005 from Rutgers University, and then worked at a startup company in NYC before deciding to pursue his PhD.

Christian F. Hempelmann, A Semantic Baseline for Spam Filtering Jan 30, 2013

This paper presents a meaning-based method to spam filtering by distinguishing text without content from text with little content from text with normal content, based on the amount of meaning that can be automatically processed in the way humans do. The basic method assumes that a semantic analyzer will be able to produce less output from semantically less grammatical input text than from semantically well-formed text. The method was pilot-tested on a corpus of blog spam. Future improvements, including a method to distinguish semantically unified from semantically disparate text are sketched. The tested method, but even more the projected improvements, will open up the way to taking the spam filtering arms race to a new level very costly to spam producers. About the speaker: Christian F. Hempelmann, is Assistant Professor of Computational Linguistics and Director of the Ontological Semantic Technology Lab at Texas A&M-Commerce. He received his PhD in 2003 from Purdue University with a specialization in ontological semantics and NLP applied to information security at the Center for Education and Research in Information Assurance and Security (CERIAS), and humor.

Wahbeh Qardaji, Differentially Private Publishing of Geospatial Data Jan 23, 2013

We interact with location-aware devices on a daily basis. Such devices range from GPS-enabled cell-phones and tablets, to navigation systems. Each device can report a multitude of location data to centralized servers. Such location information, commonly referred to as geospatial data, can have tremendous benefits if properly processed and analyzed. If shared, such geo-spatial data can have significant impact for research and other uses. Sharing such information, however, can have significant privacy implications. In this talk, we will focus on the problem of releasing static geo-spatial data in a private manner. In particular, we will explore methods of releasing a synopsis of two-dimensional datasets while satisfying differential privacy.The key challenge to anonymizing geospatial datasets while satisfying differential privacy is ensuring the utility of anonymized dataset. In particular, there are two types of error that influence the utility of anonymized datasets. The first is the anonymization noise--a direct byproduct of the differential privacy mechanism. The second is a result of the granularity of data release and the nature of the dataset itself. In this talk, we will explore methods of publishing two-dimensional datasets with utility in mind. We will analyze the current state-of-the-art methods and explore alternative grid-based approaches that best balance the two sources of error. About the speaker: Wahbeh Qardaji is a PhD candidate in the Computer Science department of Purdue University, and a member of Cerias. He received his Masters Degree in Computer Science in 2010 from Purdue University, and his Bachelors from the American University of Beirut.

Bilal Shebaro, You are Anonymous!!! Then you must be Lucky Dec 05, 2012

Services like online banking require high confidentiality due to the sensitivity of the data being transfered. As a result, online users have turned to anonymity services which offer identity protection and secure communication in their web transactions. While these services are secure and trustworthy, their popularity has attracted many attacks which result in the identification of the users. In addition, online applications are not developed with the users' anonymity in mind, which opens doors for more vulnerabilities. In this talk, I will present several attacks that anonymous users may not be aware of but which may jeopardize their anonymity. About the speaker: Bilal Shebaro is a Post Doctoral Research Associate at the Cyber Center of Purdue University. He received his Ph.D. in May 2012 from the Computer Science department at the University of New Mexico, in Albuquerque, NM, USA. His research interests are in digital forensics as well as data privacy and protection in computers and smartphones.

Ashish Kundu, A New Class of Buffer Overflow Attacks Nov 28, 2012

In this talk, we focus on a class of buffer overflow vulnerabilities that occur due to the "placement new" expression in C++. "Placement new" facilitates placement of an object/array at a specific memory location. When appropriate bounds checking is not in place, object overflows may occur. Such overflows can lead to stack as well as heap/data/bss overflows, which can be exploited by attackers in order to carry out the entire range of attacks associated with buffer overflow. Unfortunately, buffer overflows due to "placement new" have neither been studied in the literature nor been incorporated in any tool designed to detect and/or address buffer overflows. We would describe how the "placement new" expression in C++ can be used to carry out buffer overflow attacks -- on the stack as well as heap/data/bss. We show that overflowing objects and arrays can also be used to carry out virtual table pointer subterfuge, as well as function and variable pointer subterfuge. Moreover, we show how "placement new" can be used to leak sensitive information, and how denial of service attacks can be carried out via memory leakage. About the speaker: Ashish Kundu is a Research Staff Member IBM T J Watson Research Center. He works in the area of security and privacy with current focus on cloud security, and a long term vision of "end-to-end holistic security woven into the systems".

He has been an (co-)inventor in about twenty patents. He has also been awarded with the IBM Bravo award as well as three IBM Plateau awards for his contributions. This talk is based on the paper co-authored with his advisor Elisa Bertino and presented at ICDCS 2011.

Hal Aldridge, Not the Who but the What -- New applications of Hardware Identity Nov 14, 2012

An essential part of security is controlling access. Traditional access control depends on the a person's ability to prove their identity and the access control system's ability to verify their identity. For computer access, a person usually carries some combination of methods to prove their identity (password, token, and/or biometric). What if a thing needs access instead of a person? It is easy enough to embed a secret into software or hardware so a device can identify itself, but how do you ensure the integrity of that data and the identity of the device? This presentation will discuss challenges of ensuring the device is what it claims to be, how the supply chain effects the assurance level of that identity, new technologies that can be used to provide hardware based identity, and other security features than can be enabled by the secure device identity. About the speaker: Hal Aldridge is Director of Engineering at Sypris Electronics in Tampa, Florida. Dr. Aldridge has lead Cybersecurity Research and Development efforts at Sypris Electronics since joining in 2008. Prior to joining Sypris, Dr. Aldridge lead development of unmanned systems for space and security applications at Northrop Grumman and NASA.

Dr. Aldridge has a Ph.D. in Electrical and Computer Engineering from Carnegie Mellon University specializing in fault tolerant robotic control systems for space applications. Dr. Aldridge's research interests include trusted computing, secure cyber-physical systems, and fault tolerant systems.

Jianneng Cao, Publishing Microdata with a Robust Privacy Guarantee Nov 07, 2012

Today, the publication of microdata poses a privacy threat. Vast research has striven to define the privacy condition that microdata should satisfy before it is released, and devise algorithms to anonymize the data so as to achieve this condition. Yet, no method proposed to date explicitly bounds the percentage of information an adversary gains after seeing the published data for each sensitive value therein. This paper introduces \beta-likeness, an appropriately robust privacy model for microdata anonymization, along with two anonymization schemes designed therefor, the one based on generalization, and the other based on perturbation. Our model postulates that an adversary's confidence on the likelihood of a certain sensitive-attribute (SA) value should not increase, in relative difference terms, by more than a predefined threshold. Our techniques aim to satisfy a given \beta threshold with little information loss. We experimentally demonstrate that (i) our model provides an effective privacy guarantee in a way that predecessor models cannot, (ii) our generalization scheme is more effective and efficient in its task than methods adapting algorithms for the k-anonymity model, and (iii) our perturbation method outperforms a baseline approach. Moreover, we discuss in detail the resistance of our model and methods to attacks proposed in previous research. About the speaker: Jianneng is a Postdoctoral Research Associate at the cyber center of Purdue University. He obtained the Ph.D. degree in computer science from National University of Singapore in 2011. Jianneng's research interests are in data privacy, including data anonymization to hide sensitive personal information and privacy-preserving data mining, as well as access control over streaming data, private record linkage, and query processing on encrypted data.

Vaibhav Garg, Risk perception of information security risks online Oct 31, 2012

Perceived risk is informed by a myriad of affectiveassessments, nine of which have been examined rigorously for offlinerisk decisions. Is the risk voluntarily taken? Is the impact of therisk immediate or delayed? Does the individual understand theimplications of the risk? What is the perceived effectiveness ofexpert systems/judgments? Does the risk appear controllable? Is therisk new or old? Is it commonly encountered or rarely available? Doesit impact individuals or communities? How severe are the consequencesof risk taking behavior? This research examines how these ninedimensions inform perceived risk and decision-making online. Further,I examine how the determinants of perceived risk are impinged bycontext and individual awareness. About the speaker: Vaibhav Garg is a final year doctoral candidate at the School ofInformatics and Computing (SOIC), Indiana University, Bloomington(IUB). His research agenda has two core areas. The first focuses onindividual decision-making and leverages social psychology andbehavioral economics. While his focus has been security and privacydecisions online, the research has design implications in otherdomains such as health decisions. Secondly, his research examinescyber crime, both organized and individual, through theoreticalmacroeconomics as well as macro econometrics with both situated in arich tradition of criminology. This informs the design of both publicpolicy and technical systems, by regarding online decisions assituated in community norms.

Mark Guido, Detecting Maliciousness Using Periodic Mobile Forensics Oct 24, 2012

Android Phones are becoming more pervasive at MITRE's customers without any means of measuring malicious user or application behavior. More sensitive information is becoming accessible on these phones, while users have access to this data even in the most insecure of places. Without an enterprise monitoring strategy for these mobile devices, sponsors do not have the necessary data to determine when a compromise has occurred. This exposure to a user's or a malicious application's actions could leave sensitive data exposed with little recourse. There is a both a breadth and depth of information that can be gained by using physical forensic acquisition techniques against an Android phone. The resulting forensic images can be mostly treated as traditional images and can be subjected to traditional forensics tools and techniques for analysis. The MITRE Innovation Project research project "Detecting Maliciousness Using Periodic Mobile Forensics" addressed the enterprise use case of installed malicious applications. The results of the research will be discussed, as well as experimentation performed using real mobile malware. About the speaker: Mr. Mark Guido is a cyber security engineer and researcher at The MITRE Corporation, a non-profit organization chartered to work in the public interest.

Chris Kanich, Understanding Spam Economics Oct 10, 2012

Over the past two decades, the Internet has become an essential tool in the lives of millions of people. Unfortunately, this success has also attracted cybercriminals who exploit the Internet as a platform for illicit gain. Perhaps the most familiar scam is sending unsolicited advertisements (spam), clogging inboxes and putting people's computers at risk of dangerous malware infections. Understanding the mechanisms and effectiveness of these scams is essential to building effective countermeasures to cybercrime. In this talk, I'll explain the modern spamming landscape and present research that help us better understand how spammers make their money online. One effort uses the technique of botnet infiltration to examine a spam campaign from the point of view of the spammers. Botnet infiltration allows us to measure their operation including the advertisements' effectiveness and the worldwide use of spam filtering techniques. The second effort exploits key information leaks to answer key questions about the modern affiliate marketing-based spam ecosystem, from estimating their worldwide gross revenue, to understanding customer demographics and their most popular products.

Jason Haas, Global Revocation for the Intersection Collision Warning Safety Application Sep 19, 2012

Identifying and removing malicious insiders from a network is a topic ofactive research. Vehicular ad hoc networks (VANETs) may suffer frominsider attacks; that is, an attacker may use authorized vehicles toattack other vehicles. Specifically, attackers may use their vehicles tobroadcast specially formed packets that will trigger warnings in targetvehicles. This malicious behavior could have a significant detrimentaleffect on cooperative safety applications (SAs), one of the driving forcesbehind VANET deployment.We propose modifications to the intersection collision warning (ICW) SAthat enable a certificate authority (CA) to be offline and yet to decideto revoke a vehicle's certificates using retransmitted information thatcannot repudiated. Our approach differs from previous proposals in thatit is SA specific, and it is resilient to Sybil attacks. We simulate andmeasure the resources an attacker requires to attack a vehicle using theICW SA without our modifications and demonstrate that our additions reducethe false positive rate arising from errors in estimated vehicle dynamics. About the speaker: Jason J. Haas graduated from the University of Wisconsin-Madison with hisB.S. in Electrical and Computer Engineering (ECE) and Physics.

Lewis Shepherd, Challenges for R&D in the Security Field Aug 29, 2012

Long-range research into information assurance and security has seen peaks and valleys over the past three decades, mirroring larger trends including the explosive growth of Internet services and declining technology R&D investment trends. A gulf threatens to develop between the scope and scale of R&D in the private sector, and in the public sector. In particular, rapid iterative advances by commercial and black-hat entities could outstrip government's ability (particularly the US Government's ability) to perform useful basic research and advanced development of innovative tools and algorithms. Yet these malignant trends are occurring at the same time as some very exciting (but unheralded) progress in critical research areas. This talk will examine these trends, explain their context, and discuss significant implications for the field of security research -- and for the advance of trustworthy computing overall.

Christine Task, A Practical Beginners' Guide to Differential Privacy Apr 25, 2012

Differential privacy is a very powerful approach to protecting individual privacy in data-mining; it's also an approach that hasn't seen much application outside academic circles. There's a reason for this: many people aren't quite certain how it works. Uncertainty poses a serious problem when considering the public release of sensitive data. Intuitively, differentially private data-mining applications protect individuals by injecting noise which "covers up" the impact any individual can have on the query results. In this talk, I will discuss the concrete details of how this is accomplished, exactly what it does and does not guarantee, common mistakes and misconceptions, and give a brief overview of useful differentially privatized data-mining techniques. This talk will be accessible to researchers from all domains; no previous background in statistics or probability theory is assumed. My goal in this presentation is to offer a short-cut to researchers who would like to apply differential privacy to their work and thus enable a broader adoption of this powerful tool. About the speaker: Christine Task is a PhD candidate in the Computer Science department of Purdue University, and a member of CERIAS. She has five years experience teaching discrete math and computability theory at the undergraduate level. Her research interests are in differential privacy and its application to social network analysis, and her research advisor is CERIAS fellow Chris Clifton.

Steve Battista, What firmware exists in your computer and how the fight for your systems will be below your operating system Apr 18, 2012

Many security professionals look to software on hardrives as the source of compromise. To detect compromises, they use systems to check the hashes of all files on disk, When a machine is compromised, they wipe the hardrive, and assume that the machine in clean. The battlefield between attackers and defenders is moving to the firmware level. This presentation will explore what firmware exists in your computer and how the fight for your systems will be below your operating system and what can be done about this. About the speaker: Mr. Battista has over 20 years of professional experience in securing systems, creating architectures, examining research, and running programs. During this time has focused on large federal government and infrastructure systems. He currently works for MITRE as a lead cyber security engineer.

Traian Truta, : K-Anonymity in Social Networks: A Clustering Approach Apr 11, 2012

The proliferation of social networks, where individuals share private information, has caused, in the last few years, a growth in the volume of sensitive data being stored in these networks. As users subscribe to more services and connect more with their friends, families, and colleagues, the desire to use this information from the networks has increased. Online social interaction has become very popular around the globe and most sociologists agree that this will not fade away. Social network sites gather confidential information from their users (for instance, the social network site PacientsLikeMe collects confidential health information) and, as a result, social network data has begun to be analyzed from a different, specific privacy perspective. Since the individual entities in social networks, besides the attribute values that characterize them, also have relationships with other entities, the risk of disclosure increases. In this talk we present a greedy algorithm for anonymizing a social network and a measure that quantifies the information loss in the anonymization process due to edge generalization. About the speaker: Traian Marius Truta is an associate professor of Computer Science at Northern Kentucky University. He received his Ph.D. in computer science from Wayne State University in 2004. His major areas of expertise are data privacy and anonymity, privacy in statistical databases, and data management.

Randall Brooks, Adding a Software Assurance Dimension to Supply Chain Practices Mar 21, 2012

There is a long history of supply chain management, from which many related policies, practices, processes, and enabling artifacts have been developed and employed by those business enterprises that acquire hardware and software components from a third party. Traditionally, Supply Chain Risk Management (SCRM) has been the focal point of supply chain practices and has focused on business and contractual issues, although recent efforts have increasingly included engineering expertise for product quality evaluations.This presentation advocates the introduction of a security assurance dimension to the SCRM process. It does not, however, propose the addition of an independent, parallel track of SCRM process for security assurance evaluation, but rather practical steps for augmenting those SCRM processes that already exist.Just as is the case in legacy SCRM, the cyber dimension of SCRM is based on assessing and balancing risk vs. cost. The goal is to minimize the added costs associated with improved information assurance by efficiently incorporating relevant practices industry, government, and academia to provide a security assurance dimension into the supply chain process.SCRM-relevant industry and government practices will be presented in this paper in such a way that supply chain staff can easily make use of them, even without a background in information security. Also, it will be clearly noted when subcontract management, information assurance engineering, or other business or technical expertise may be needed to complement traditional supply chain activities in the pursuit of cyber-based SCRM.Points of discussion common to both hardware and to software component acquisition will include:1. Acquirer business risk2. End customer mission criticality and mission assurance3. Subcontract management4. Supplier secure development assessment5. Supplier management practices for their suppliers6. Supplier business assessment7. Product assessmentPoints of discussion peculiar to hardware component acquisition will include:1. Quality vs. counterfeiting vs. malicious alteration2. ASICS, FPGAs, and microprocessors3. Information storage in volatile memory4. Information storage in non-volatile memory and permanent disk storagePoints of discussion peculiar to software component acquisition will include:1. COTS, contracted software, open source, and freeware2. Software pedigree and provenance3. License management of open source About the speaker: Mr. Brooks, a twelve year Raytheon employee, is an Engineering Fellow in the Cyber Defense Solutions business area in Largo, FL.

Chenyun Dai, Privacy-Preserving Assessment of Location Data Trustworthiness Mar 07, 2012

Assessing the trustworthiness of location data corresponding toindividuals is essential in several applications, such as forensicscience and epidemic control. To obtain accurate and trustworthylocation data, analysts must often gather and correlate informationfrom several independent sources, e.g., physical observation, witnesstestimony, surveillance footage, etc. However, such information may befraudulent, its accuracy may be low, and its volume may be insufﬁcientto ensure highly trustworthy data. On the other hand, recentadvancements in mobile computing and positioning systems, e.g.,GPS-enabled cell phones, highway sensors, etc., bring new andeffective technological means to track the location of an individual.Nevertheless, collection and sharing of such data must be done in waysthat do not violate an individual's right to personal privacy.Previous research efforts acknowledged the importance of assessinglocation data trustworthiness, but they assume that datais available to the analyst in direct, unperturbed form. However, suchan assumption is not realistic, due to the fact that repositories ofpersonal location data must conform to privacy regulations. In thiswork, we study the challenging problem of reﬁning trustworthiness oflocation data with the help of large repositories of anonymizedinformation. We show how two important trustworthiness evaluationtechniques, namely common pattern analysis and conﬂict/supportanalysis, can beneﬁt from the use of anonymized location data. We haveimplemented a prototype of the proposed privacy-preservingtrustworthiness evaluation techniques, and the experimental resultsdemonstrate that using anonymized data can signiﬁcantly help inimproving the accuracy of location trustworthiness assessment. About the speaker: Chenyun Dai is currently a 5th year Ph.D. student in Computer ScienceDepartment at Purdue University. He got his master degree in computerscience from Purdue University in 2010. Before coming to Purdue, hegot a master degree and a bachelor degree, both in computer science,from Fudan University and East China Normal University respectively.His Ph.D. dissertation addresses the development of a trustworthinessmodels for information concerning locations of individuals. Theavailability and correctness of this information is crucial forimportant applications, namely forensics, criminal investigations, anddisease control and monitoring. A paper reporting the first results ofthis research was accepted and presented at the 2009 ACM SIGSPATIALGIS Conference. More recently he has developed a major extension tohis model that supports the assessment of location data when locationdata are only available in anonymized form and the work was publish in2011 ACM SIGSPATIAL GIS Conference. He is currently extending thiswork to support more sophisticated models for locations andtrajectories, uncertain data and social network data.

Ben Calloni, Vulnerability Path and Assessment Feb 22, 2012

US Government, Department of Defense, and Enterprise computer systems must be trusted to protect data with varying levels of sensitivity / security. Affordability requirements are driving the need to incorporate many diverse commercial software products of unknown quality and pedigree into said systems. While there exist many Static Code Analysis products, the depth, rigor, and coverage of these tools is incomplete and inconsistent. In addition, finding and eliminating computer flaws or weaknesses is not the same as determining true vulnerabilities. Further there is significant cost reduction that can occur if automated support for establishing the case for trust and assurance can be achieved. The collection of evolving standards known as the OMG Software Assurance (SwA) Ecosystem is supported and endorsed by AFRL, NIST, SEI, OSD/NII, and DHS Cyber Security Division among others. The SwA Ecosystem defines several standard protocols to enable interoperability for tools, services and security researchers in developing, exchanging and utilizing machine-readable content (e.g. vulnerability patterns, enumerations, rules) for security assurance of existing software based systems. This standard-based plug-and-play framework integrates software analysis and data mining tools and facilitates highly automated fact-oriented approach to assurance by providing traceability link between assurance claims and high-fidelity system facts as evidence to justify assurance claims. This presentation will focus on the work funded by AFRL and OSD/NII to addressing the Vulnerability Path Assessment piece of the Ecosystem. About the speaker: Dr. Ben Calloni is a Lockheed Martin Fellow for Software Security and a Certified Information Systems Security Professional (CISSP). He is a senior research program manager of Aeronautics Company in Fort Worth assigned to the Advanced Development Programs, formerly known as "The Skunk Works".

He is partnered with Air Force Research Labs, the National Security Agency, and Department of Defense Networks and Information Integration office, and several commercial off the shelf suppliers, to provide international standards based, COTS product based, Multi Level Security infrastructures applicable for Department of Defense weapon systems and for the Department of Homeland Security (DHS) as well.

Simson Garfinkel, Forensic Carving of Network Packets with bulk_extractor and tcpflow Feb 15, 2012

Using validated carving techniques, we show that popular operating systems (\eg Windows, Linux, and OSX) frequently have residual IP packets, Ethernet frames, and associated data structures present in system memory from long-terminated network traffic. Such information is useful for many forensic purposes including establishment of prior connection activity and services used; identification of other systems present on the system's LAN or WLAN; geolocation of the host computer system; and cross-drive analysis. We show that network structures can also be recovered from memory that is persisted onto a mass storage medium during the course of system swapping or hibernation.We present our network carving techniques, algorithms and tools, and validate these against both purpose-built memory images and a readily available forensic corpora. These techniques are valuable to both forensics tasks, particularly in analyzing mobile devices, and to cyber-security objectives such as malware analysis.

George Vanecek, Is it Time to add Trust to the Future Internet/Web? Feb 01, 2012

The future web, and Internet, are undergoing a humanization of their technologies which increasingly make their services more personalized, individualized and transparent. This is jointly fueled by the inexpensive yet easily accessible huge computing and storage capacities in clouds, the adoption of personal, mobile smart devices used across consumer/enterprise interchangeably, and the emergence of personal agents and services attaining personalized perception of the real-world and its control on behalf of the users. In this human/machine convergences, trust is being recognized as potentially playing a huge role in addressing future human/machine security, commerce and social on-line issues. However, trust has been adopted only partially and independently by certain services and not made integral in the fabric of the Internet or the web.This talk explores the technical and social issues for the establishment of a ubiquitous trust network in the Future Internet. The talk reviews necessary technologies from the Semantic Web, Intercloud, and broader Identity methodologies, and provides a number of use cases for how the Future Internet would benefit from the trust network.

Frank Tompa, A Flexible System for Access Control Jan 25, 2012

A variety of mechanisms have been used in access control systems to support enterprises' diverse security needs. For example, some enterprises might allow individual users to assign privileges on files that they own, whereas others might require that permissions be granted and revoked by security administrators only; some enterprises wish to operate under closed access policies (where permission is denied unless explicitly granted), whereas others prefer to allow access only if the number of positive authorizations exceeds the number of negative ones. We will explore two frameworks, namely creation time policies and conflict resolution policies, that together allow software vendors to support a wide variety of discretionary access control mechanisms using a single code base. About the speaker: Frank Tompa has been on the faculty in Computer Science at the University of Waterloo since 1974. His teaching and research interests are in the fields of data structures and databases, particularly the design of text management systems suitable for maintaining large reference texts and large, heterogeneous text collections. He has co-authored papers in the areas of database dependency theory, storage structure selection, query processing, materialized view maintenance, text matching, XML processing, structured text conversion, database integration, data retention and security, and text classification. In 2005, the University of Waterloo and the City of Waterloo announced the naming of the road Frank Tompa Drive in recognition of Professor Tompa being one of those who "epitomize the energy and enterprise that characterize the University of Waterloo." In 2010, he was named a Fellow of the ACM for contributions to text-dominated and semi-structured data management.

Salmin Sultana, Secure Provenance Transmission for Data Streams Jan 18, 2012

Many application domains, such as real-time financial analysis, e-healthcare systems, sensor networks, are characterizedby continuous data streaming from multiple sources and through intermediate processing by multiple aggregators. Keeping track ofdata provenance in such highly dynamic context is an important requirement, since data provenance is a key factor in assessingdata trustworthiness which is crucial for many applications. Provenance management for streaming data requires addressing severalchallenges, including the assurance of high processing throughput, low bandwidth consumption, storage efficiency and secure transmission. In this talk, I will discuss a novel approach to securely transmit provenance for streaming data (focusing on sensor network) by embedding provenance into the inter-packet timing domain while addressing the above mentioned issues. As provenance is hidden in another host-medium, our solution can be conceptualized as watermarking technique. However, unlike traditional watermarking approaches, we embed provenance over the inter-packet delays rather than in the sensor data themselves, hence avoiding the problem of data degradation due to watermarking. Provenance is extracted by the data receiver utilizing an optimal threshold-based mechanism which minimizes the probability of provenance decoding errors. The resiliency of the scheme against outside and inside attackers is established through an extensive security analysis. Experiments show that our technique can recover provenance upto a certain level against perturbations to inter-packet timing characteristics. About the speaker: Salmin Sultana is pursuing her PhD in Computer Engineering in the School of ECE at Purdue University. Her research interests include secure data provenance, security and fault tolerance of distributed systems, such as cloud computing, power grid, and high performance computing. She is a member of the Center for Education and Research in Information Assurance and Security (CERIAS).

Loukas Lazos, Jam me if you can: Mitigating the Impact of Inside Jammers Nov 16, 2011

The open nature of the wireless medium leaves wireless communications exposed to interference caused by the concurrent operation of co-located wireless devices over the same frequency bands. While unintentional signal interference is managed at the physical and mac layers using an array of techniques (advanced signal processing, channel coding and error correction, spread spectrum communications, multiple access protocols, etc.), in a hostile environment, wireless communications remain vulnerable to intentional interference attacks typically referred to as jamming. Jamming can take the form of an external attack launched by "foreign" devices that are unaware of the network secrets (e.g., cryptographic credentials) or its protocols. Such external attacks are relatively easy to neutralize through a combination of cryptography-based measures andspreading techniques. In contrast, when jamming attacks are launched from compromised nodes, they are much more sophisticated in nature.These attacks exploit knowledge of network secrets (e.g., cryptographic keys and pseudo-random spreading codes) and its protocol semantics to maximize their detrimental impact by selectively and adaptively targeting critical data transmissions. In this talk, wediscuss the feasibility and impact of selective jamming attacks in the presence of inside adversaries. The attacker's selectivity is considered at different granularities, namely on a per-channel basis and on a per-packet basis. We describe several mitigation methods thatdo not rely on the existence of shared secrets, but defeat selectivity via a combination of temporary packet hiding and uncoordinated frequency hopping.

Zhongshu Gu, Process Implanting: A New Active Introspection Framework for Virtualization Nov 09, 2011

Previous research on virtual machine introspection proposed "out-of-box" approach by moving out security tools from the guest operating system. However, compared to the traditional "in-the-box" approach, it remains a challenge to obtain a complete semantic view due to the semantic gap between the guest VM and the hypervisor.In this paper, we present Process Implanting, a new active VM introspection framework, to narrow the semantic gap by implanting a process from the host into the guest VM and executing it under the cover of an existing running process. With the protection and coordination from the hypervisor, the implanted process can run with a degree of stealthiness and exit gracefully without leaving negative impact on the guest operating system. We have designed and implemented a proof-of-concept prototype on KVM which leverages hardware virtualization. We also propose and demonstrate application scenarios for Process Implanting in the area of VM security. About the speaker: Zhongshu Gu is a Ph.D. student from department of computer science atPurdue University.

Sheila Becker, Securing Application-Level Topology Estimation Networks: Facing the Frog-Boiling Attack Oct 26, 2011

Peer-to-peer real-time communication and media streaming applicationsoptimize their performance by using application-level topology estimationservices such as virtual coordinate systems. Virtual coordinate systems allownodes in a peer-to-peer network to accurately predict latency between arbitrarynodes without the need of performing extensive measurements. However, systemsthat leverage virtual coordinates as supporting building blocks, are prone toattacks conducted by compromised nodes that aim at disrupting, eavesdropping,or mangling with the underlying communications.Recent research proposed techniques to mitigate basic attacks (inflation, deflation,oscillation) considering a single attack strategy model where attackers performonly one type of attack. In this work we explore supervised machine learningtechniques to mitigate more subtle yet highly effective attacks (frog-boiling,network-partition) that are able to bypass existing defenses. We evaluate ourtechniques on the Vivaldi system against a more complex attack strategy model,where attackers perform sequences of all known attacks against virtual coordinatesystems, using both simulations and Internet deployments.

Julia M. Taylor, Victor Raskin, and Eugene H. Spafford, Ontological Semantic Technology Goes Phishing Oct 19, 2011

The talk reports on an early stage of on-going research on the application of computational semantic techniques to detect phishing, i. e., mass mailings intended to sweep up personal details for later malicious use by the phishers themselves or their potential customers. Our personal experience as targets of phishing has shown that the texts are getting increasingly polished, plausible, and sophisticated, often making it difficult even for humans to tell phishing from bona fide, if unadvised messages. In this talk, we will demonstrate, on a few examples, how Ontological Semantic Technology can help to achieve machine natural language understanding that allows the computer to match and, augmented by the best existing technologies, possibly exceed human ability to detect the meaning-based clues pointing to phishing and to reason accordingly. We will also discuss the problem of automatic phishing detection and share our thoughts on applying the most feasible and promising techniques on a large corpus of phishing emails.

Xukai Zou, Weighted Multiple Secret Sharing Sep 28, 2011

Secret sharing is important in information and network security and has broad applications in the real world. Since an elegant secret sharing mechanism was first proposed by Shamir in 1979 (also Blakley did the similar work then), many schemes have appeared in literature. These schemes deal with either single or multiple secrets and their shares have either the same weight or different weights. Weighted shares mean that different shares have different capabilities in recovering the secret(s) -- a more (less) weighted share needs fewer (more) other shares to recover the secret(s). In this talk, we will first discuss two primary categories of (representative) methods implementing secret sharing: polynomial based, i.e., Shamir's scheme, and Chinese Remainder Theorem (CRT) based, i.e., Mignotte's scheme. Then we present a new CRT based weighted multiple secret sharing scheme, based on the identification of a direct relation between the length (i.e., the number of bits) and the weight of shares. The new scheme can also be naturally applied to other cases such as sharing a single secret with same-weight shares and is remarkably simple and easy to implement. Compared to both Shamir's scheme and Mignotte's scheme, the new scheme is more efficient than both schemes in share computation and more efficient than Shamir's scheme (and as efficient as Mignotte's scheme) in secret recovery. One prominent and unique advantage of the new scheme is that it admits non-whole number weights which the existing schemes have not offered. Thus, the sizes of shares can vary distantly in fine-tuned granularity to fit different requirements and constraints of various devices such as sensors, PDAs, cell phones, iPads and to allow the new scheme to apply to broader applications involving wireless/sensor networks and pervasive computing.

Joe Leonard, Methods and Techniques for Protecting Data in Real Time on the Wire Sep 21, 2011

The ongoing explosion of data and information throughout the enterprise is undeniable. Sensitive data, whether structured or unstructured, finds itself replicated and dispersed. This creates a challenge for information security professionals to prevent the flow of this information to unauthorized or inappropriate destinations.The security community has made great progress in protecting this data and information while it is at rest or in use. But ... is there more that can be done?Companies are now asking, "Who moved my data and where did it go? Was it an appropriate flow from one internal department to another? Was the flow intended for a trusted business partner? Or ... was my data heading for an unknown destination, a competitor or a pool of cybercriminals?"End point controls, access controls, database monitoring and encryption are all important components of a solid layered security approach. However tools that provide visibility and control over "data in motion" deliver critical capabilities that none of these other components can adequately address. When prioritizing various components or layers of an information security implementation, it has been argued that a solid "data in motion" component can provide 80% of the bang for 20% of the buck (and effort!)This presentation focuses on methods and techniques in wire speed detection and control of data in motion. The presentation will include:approaches to detecting simple patterns emphasizing low false positivesadvances in wire speed pattern matching enabling protection of specific fields or combination of fields in a databasepolicy designs that combine network application controls with content identification and controlwire speed blocking that does not require a proxy About the speaker: Mr. Leonard is responsible for bringing to market an advanced Deep Packet Inspection device focused on Information Leak Prevention and other leading edge security applications for Global Velocity.He has spent over 25 years in Communications Technology, with experience ranging from Military systems to global fortune 100 networks to modern day internet solutions.

Joe has also held various technical and management positions with Compaq Computer, and MCI Communications focused primarily on wide area and local area data networking solutions.

David Zage, What does Knowledge Discovery, Predictability, and Human Behavior have to do with Computer Security Sep 14, 2011

Vast resources are devoted to predicting human behavior in domainssuch as economics, popular culture, and national security, but thequality of such predictions is often poor. Thus, it is tempting toconclude that this inability to make good predictions is a consequenceof some fundamental lack of predictability on the part of humans.However, recent work offers evidence that the failure of standardprediction methods does not indicate an absence of humanpredictability but instead reflects:1. misunderstandings regarding which features of human dynamicsactually possess predictive power2. the fact that, until recently, it has not been possible to measurethese predictive features in real world settings.This talk introduces some of the science behind these basicobservations and demonstrates their utility in various case studies.We begin by considering social groups in which individuals areinfluenced by the behavior of others. Correctly identify andunderstanding the social forces in these situations can increase theextent to which the outcome of a social process can be predicted inits very early stages. This finding is then leveraged to designprediction methods which outperform existing techniques for predictingsocial network dynamics. We also look at the analysis of thepredictability of adversary behavior in the co-evolutionary "armsraces" that exist between attackers and defenders in many domains. Ouranalysis reveals that conventional wisdom regarding these co-evolvingsystems is incomplete, and provides insights which enable thedevelopment of predictive methods for computer network security. About the speaker: David Zage is a senior member of Sandia National Laboratories in theCyber Analysis R&D group. His main research interest are in the areasof security, networking, and distributed systems. David received hisPh.D. in computer science from Purdue University in 2010 and his B.S.in computer science from Purdue in 2004.

Steven Gianvecchio, Detecting Bots in Online Games using Human Observational Proofs Sep 07, 2011

The abuse of online games by automated programs, known as bots, hasgrown significantly in recent years. The conventional methods fordistinguishing bots from humans, such as CAPTCHAs, are not effective ina gaming context. This talk presents a non-interactive approach based onhuman observational proofs for continuous game bot detection. HOPsdifferentiate bots from human players by passively monitoring inputactions that are difficult for current bots to perform in a human-likemanner. The talk describes a prototype HOP-based game bot defense systemthat analyzes user-input actions with a cascade-correlation neuralnetwork to distinguish bots from humans. The experimental results showthat the HOP system is effective in capturing game bots in World ofWarcraft, raising the bar against game exploits and forcing attackers tobuild more complicated bots for detection evasion in the future. About the speaker: Steven Gianvecchio received his Ph.D. in Computer Science from theCollege of William and Mary in 2010. He is a Senior Scientist at theMITRE Corporation, McLean, VA. His research interests include networks,distributed systems, network monitoring, intrusion detection, traffic modeling, and covert channels.

Tamir Tassa, Non-homogeneous Anonymizations Aug 31, 2011

Privacy Preserving Data Publishing (PPDP) is an evolving research field that is targeted at developing anonymization techniques to enable publishing data so that privacy is preserved while data distortion is minimized. Up until recently most of the research on PPDP considered partition-based anonymization models. The approach in such models is to partition the database records into groups and then homogeneously generalize the quasi-identifiers in all records within a group, as a countermeasure against linking attacks. We describe in this talk alternative anonymization models which are not based on partitioning and homogeneous generalization. Such models extend the set of acceptable anonymizations of a given table, whence they allow achieving similar privacy goals with much less information loss. We shall briefly review the basic models of homogeneous anonymization (e.g. k-anonymity and l-diversity) and then define non-homogeneous anonymization, discuss its privacy, describe algorithms and demonstrate the advantage of such anonymizations in reducing the information loss. We shall then discuss the usefulness of those models for data mining purposes. In particular, we will show that the reduced information loss that characterizes such anonymizations translates also to enhanced accuracy when using the anonymized tables to learn classification models. Based on joint works with Aris Gionis, Arnon Mazza, Mark Last and Sasha Zhmudyak About the speaker: Tamir Tassa is a member of the Department of Mathematics and Computer Science at The Open University of Israel. Previously, he served as a lecturer and researcher in the School of Mathematical Sciences at Tel Aviv University, and in the Department of Computer Science at Ben Gurion University.

Eric Katz, Mobile Phones and Evidence Preservation Apr 27, 2011

Jose Fernandez, Semantic Security: or How I Learned to Stop Worrying and Looooooove the Internet Apr 20, 2011

My late friend Robert Garigue, a pioneer of Information Warfare and one of the most original and visionary corporate Chief Information Security Officer, first described the notion a "semantic attack" as the eventual non plus ultra in the hacking arsenal. Semantic attacks do not target directly the information-carrying or information-bearing portions of a system, but rather those components of the system that give it meaning and value; i.e. the semantic components that help us, among other things, establish and maintain truth and trust. When Garigue first coined the phrase "Hack not system, hack the belief system" many of us misinterpreted this as a cry for addressing the non-electronic non-technological "soft" components of the system, i.e. humans and their decision making cycles. In fact, social engineering, phishing attacks and other forms of internet-based cons are in some sense instances of such cyber-mediated attacks on the"meat computers" we have in our brains. However, reality is fast catching up with Science Fiction, and our decision making whether as citizens in a democracy, consumers, military leaders, politicians, businessmen and even intellectuals, is increasingly depending on Internet-based sources and systems. Our increased use and reliance on search engines, social networks, blogospheres, wikis and other non traditional media, for our daily decision making has made it such that an increased portion of the semantic system is computer-based. How are we to define, evaluate or measure the security of these new cybernetic semantic components? Join me on a highly speculative tour of "Semantic Security" (tm), a new subfield of Computer Security, ripe with lots of low-hanging, easily solvable research problems. Believe me!! About the speaker: Dr. Fernandez became an assistant professor in the Department ofComputer & Software Engineering at the …cole Polytechnique de MontrÈal in 2004, time at which he forsook all previous research attempts in Quantum Computing, Computational Complexity and Cryptography (he was just not that good at it). He now heads the laboratory for Information Security Research (Lab SecSI, in French), where his current research interests include malware analysis, botnet command and control, denial of service attacks, intrusion detection, security product testing methodologies, security and integration of logical and physical access control systems, semantic security and theory of cyber conflict. He holds bachelors in Math and in Computer Engineering from MIT, a Master's from University of Toronto, and a Ph.D. from Universite de Montreal.

Ronda R. Henning, FuzzyFusion™, an application architecture for multisource information fusion Apr 13, 2011

Carter Bullard, Society, Law Enforcement and the Internet: Models for Give and Take Apr 06, 2011

Krannert Auditorium, Purdue University, West Lafayette, INThe interaction of society, law enforcement and telecommunications has evolved over the last 140 years to a successful balance of give and take. Society gives, providing well-defined processes and procedures that allow the government, law enforcement and citizens regulated access to information routinely collected by telecommunications service providers. And society benefits, where its justice systems can effectively use the information in support of criminal investigations and civil dispute resolutions.Internet technology has been designed, developed and deployed without any consideration to this relationship, and the technical and social void that has emerged isactively being exploited, reducing the security of the Internet, and the natural compensatory actions threaten innovation and privacy.Our presentation discusses how a comprehensive policy regarding Internet communications identifying information (CII), could align the Internet with the existing public private partnerships that have evolved, minimizing the threats to privacy that an Internet ‘wiretapping' strategy alone could generate. About the speaker: Carter Bullard is a pioneer and industry expert, holding both academic and industry positions researching computer network security. Carter established in the early 1990's, research programs in network vulnerability analysis and assessment at Carnegie Mellon's CERT, where he pioneered and developed the concepts of network flow based forensics, and situational awareness.

Casey Deccio, Modeling DNS Security: Misconfiguration, Availability, and Visualization Mar 02, 2011

The Domain Name System (DNS) is one of the components most critical toInternet functionality. The ubiquity of the DNS necessitates both theaccuracy and availability of responses. While the DNS SecurityExtensions (DNSSEC) add authentication to the DNS, they also increasethe complexity of an already complex name resolution system. Manydeployments have suffered from server misconfiguration or maintenanceneglect which increase the likelihood of name resolution failure for adomain name, even if servers are responsive.Our research introduces metrics for quantifying DNSSEC availability andevaluates these metrics on production signed DNS zones to show thepervasiveness of misconfiguration. We present methodology forincreasing robustness of name resolution in the presence of DNSSECmisconfiguration. In our survey of production signed zones, we observethat nearly one-third of the validation errors detected might bemitigated using the technique proposed in our research.As part of my talk, I will also demo an online DNS visualization tooldesigned to assist administrators in identifying critical issues withtheir DNSSEC deployments.This is joint work with researchers at UC Davis and Intel Corporation.

Jan Vitek, A couple of results about JavaScript Feb 23, 2011

This talk will summarize two recent results on JavaScript."The Eval that Men Do": Transforming text into executable code with a function such as JavaScript's eval endows programmers with the ability to extend applications, at any time, and in almost any way they choose. But this expressive power comes at a price. Reasoning about the dynamic behavior of programs that use this features becomes difficult. A better understanding of how eval is used could lead to increased performance and security. I will report on a large-scale study of the use of eval in JavaScript-based web applications. We have recorded the behavior 317 MB of strings given as arguments to 481,844 calls to the eval function. We provide statistics on the nature and content of strings used in eval expressions, as well as their provenance and data obtained by observing their dynamic behavior."Flexible Access Control Policies with Delimited Histories and Revocation": Providing security guarantees for software systems built out of untrusted components requires the ability to enforce fine-grained access control policies. This is evident in Web 2.0 applications where JavaScript code from different origins is often combined on a single page, leading to well-known vulnerabilities. We present a security infrastructure which allows users and content providers to specify access control policies over delimited histories and allows for revocation of the history, and reversion to a safe state if a violation is detected. We report on an empirical evaluation in the context of a production browser. We show examples of security policies which prevent real attacks without imposing drastic restrictions on legacy applications. We have evaluated our proposal with two non-trivial policies on 50 of the Alexa top websites with no changes to the legacy JavaScript code. Between 72% and 84% of the sites were fully functional, and only 1 site was rendered non-functional. About the speaker: Jan Vitek is a Professor of Computer Science at Purdue. He works on programming language technologies with applications to real-time computing.

There is considerable research being conducted on insider threats directed to developing new technologies. At the same time, existing technology is not being fully utilized because of non-technological issues that pertain to economics and the human dimension. Issues related to how insiders actually behave are critical to ensuring that the best technologies are meeting their intended purpose. In our research, we have investigated accepted models of perceptions of risk and characteristics unique to insider threat, and we have introduced ordinal scales to these models to measure insider perceptions of risk. We have also investigated decision theories, leading to a conclusion that prospect theory, developed by Tversky and Kahneman, may be used to describe the risk-taking behavior of insiders and can be accommodated in our model. Our results indicate that there is an inverse relationship between perceived risk and benefit by insiders and that their behavior cannot be explained well by the models that are based on the traditional methods of engineering risk analysis and expected utility. We discuss the results of validating that model with forty-two senior information security executives from a variety of organizations. We also discuss how the model may be used to identify characteristics of insiders' perceptions of risk and benefit, their risk-taking behavior and how to frame insider decisions. Finally, we recommend understanding risk of detection and creating a fair working environment to reduce the likelihood of committing criminal acts by insiders.

Torsten Braun, User and Machine Authentication and Authorization Infrastructure for Distributed Testbeds Jan 26, 2011

The Wisebed wireless sensor network testbed provides a federated experimentation facility covering several European universities. For scalable management of access control we have designed and implemented a single-sign-on and attribute-based authentication and authorization infrastructure based on the Shibboleth software, which has been developed by the Internet2 Middleware Initiative. Shibboleth is usually used for protecting browser-based access of web resources. We have designed and implemented an extension to protect web services using the Simple Object Access Protocol. This extension allows both user and machine authentication for web services. As a proof of concept, we implemented a complete reservation system for sensor nodes in the Wisebed test-bed federation. Two different user interfaces based on a web page and an iPhone application have been implemented. Although implemented for Shibboleth, the architecture can be easily adapted to other authentication and authorization infrastructures. About the speaker: Torsten Braun got his Ph.D. degree from University of Karlsruhe (Germany) in 1993. From 1994 to 1995 he has been a guest scientist at INRIA Sophia-Antipolis (France).

Somesh Jha, Retrofitting Legacy Code for Security Jan 19, 2011

Research in computer security has historically advocated Design forSecurity, the principle that security must be proactively integratedinto the design of a system. While examples exist in the researchliterature of systems that have been designed for security, there arefew examples of such systems deployed in the real world. Economic andpractical considerations force developers to abandon security andfocus instead on functionality and performance, which are moretangible than security. As a result, large bodies of legacy code oftenhave inadequate security mechanisms. Security mechanisms are added tolegacy code on-demand using ad hoc and manual techniques, and theresulting systems are often insecure.This talk advocates the need for techniques to retrofitsystems with security mechanisms. In particular, it focuses on theproblem of retrofitting legacy code with mechanisms for authorizationpolicy enforcement. It introduces a new formalism, calledfingerprints, to represent security-sensitive operations. Fingerprintsare code templates that represent accesses to security-criticalresources, and denote key steps needed to perform operations on theseresources. This talk develops both fingerprint mining andfingerprint matching algorithms.Fingerprint mining algorithms discover fingerprints ofsecurity-sensitive operations by analyzing source code. Thistalk presents two novel algorithms that use dynamic programanalysis and static program analysis, respectively, to minefingerprints. The fingerprints so mined are used by the fingerprintmatching algorithm to statically locate security-sensitiveoperations. Program transformation is then employed to staticallymodify source code by adding authorization policy lookups at eachlocation that performs a security-sensitive operation.These techniques have been applied to three real-world systems. Thesecase studies demonstrate that techniques based upon program analysisand transformation offer a principled and automated alternative to thead hoc and manual techniques that are currently used to retrofitlegacy software with security mechanisms. Time permitting, we willtalk about other problems in the context of retrofitting legacy codefor security. I will also indicate where ideas from model-checking have been used in this work.

Fariborz Farahmand, Risk Perception and Trust in Cloud Jan 12, 2011

Many companies today are paying attention to cloud computing and new aspects of large-scale, distributed computing. This emerging paradigm of the information age offers exciting benefits to companies and users, but cloud computing, like any other innovation, faces challenges such as security and privacy risks. How do different stakeholders perceive these risks and the effectiveness of the mitigations? And, how are these reflected in their trust in the cloud? The answers to these questions can affect the outcome of policy debates, and the allocation of resources in controlling security issues of cloud environments. This work presents an introduction to the cloud and some of its advantages and disadvantages. It discusses the role of risk perception and trust in security and privacy challenges of the cloud. It also makes recommendations addressing these challenges. About the speaker: Fariborz Farahmand received his Ph.D. in information and computer science from the Georgia Institute of Technology.

Matthew Hashim, Nudging the Digital Pirate: Behavioral Issues in the Piracy Context Dec 01, 2010

Piracy is a significant source of concern facing software developers, music labels, and movie production companies. Firms continue to invest in digital rights management technologies to thwart piracy, but their efforts are quickly defeated by hackers and pirates. In the context of piracy, we observe a surprising phenomenon: pirates may often choose to purchase the digital good after pirating it. This is quite interesting given the minimal risk of being caught. Since piracy is often considered a victimless crime, we theorize that moral obligation may mediate other constructs from the theory of planned behavior. We believe this is a consequence of the desire for an individual to rationalize unethical behavior, especially when the crime is victimless. We also identify under what circumstances an individual might be susceptible to exogenous nudging from a software company. Salient constructs under initial purchase and piracy conversion intentions are compared to document under which situations they become relevant to the potential pirate. About the speaker: Matthew J. Hashim is a Ph.D. candidate of Management Information Systems in the Krannert School of Management at Purdue University. His primary research interest is in the behavioral aspects of piracy, particularly the role of information in the piracy decision, including the conversion of pirates to paying customers. His research links the information systems literature with interdisciplinary concepts from social psychology and behavioral economics through the use of empirical and analytical research methodologies. Matthew received his M.B.A. from California State University, Fresno in 2003, and his B.S. in Business Administration from California Polytechnic State University, San Luis Obispo in 1999. Matthew worked in industry for approximately 10 years, with experience in IT security, ERP implementation and development, forensics, and other management and IT-related roles.

Michael Kirkpatrick, Security Applications for Physically Unclonable Functions Nov 17, 2010

Physically unclonable functions (PUFs) are hardware structures that create unique characteristics for distinct copies of a device. Specifically, the physical nature of manufacturing a device introduces slight variations that can be neither controlled nor predicted. PUFs quantify these differences into a random one-way function. In our work, we have explored multiple application scenarios for integrating PUFs into security systems.In the first application, we propose leveraging PUFs to bind access requests to known, trusted devices. This scheme also offers a lightweight key exchange protocol that can reduce the computational cost for low-power embedded devices. In our second work, we have designed PEAR, a portable authentication token based on PUFs that allows for privacy-preserving transactions with websites. Finally, we have created PUF ROKs, which are read-once cryptographic keys based on PUFs. In this talk, we will introduce these applications, highlighting the advantages of deploying PUFs over competing technologies, as well as presenting the results of our empirical and formal analyses of these prototypes. About the speaker: Michael S. Kirkpatrick is a Ph.D. candidate in the Department of Computer Sciences at Purdue University. His research interests lie in the realm of designing secure systems, with a special focus on the interactions between hardware, architectures, and operating systems.

Nikita Borisov, Detecting Coordinated Attacks with Traffic Analysis Nov 10, 2010

Coordinated attacks, such as botnets, present a major threat to today's computing infrastructures. They are able to evade traditional detection techniques by using zero-day and polymorphic exploits, partitioning misbehavior, and encrypting communications. I will discuss our work that aims to identify coordinated activity itself by analyzing the patterns of network communication and inferring information via the available side information. First, I will discuss the detection of linked network flows that relay traffic across compromised computers, called stepping stones. We use statistical techniques to locate timing correlation between flows, aided by active perturbation of network delays to insert a specialized pattern, called a watermark. I will show that the use of watermarks provides superior detection performance over passive correlation and present two watermark designs: RAINBOW, a low-overhead watermark for enterprise-level stepping stone detection, and SWIRL, a scalable design that can be used in the wide area.I will then discuss our work on using community detection to locate groups of computers organized into a structured peer-to-peer topology. Our tool, BotGrep, finds tightly connected components in communication graphs using several graph-theoretic metrics and heuristics. It is designed to scale to very large data sets, allowing large core ISPs to detect previously unknown peer-to-peer botnets. About the speaker: Nikita Borisov is an assistant professor at the University of Illinois at Urbana-Champaign. His research interests are network security and online privacy. He is the co-designer of the ``off-the-record'' (OTR) instant messaging protocol and was responsible for the first public analysis of 802.11 security.

Trent Jaeger, Tackling System-Wide Integrity Nov 03, 2010

Computing system compromises occur because system integrity is not managed effectively. The various parties that contribute to a system, programmers, OS distributors, and system administrators, do not account for integrity threats comprehensively, leading to recurrence of the same kinds of attacks. The problem is that we lack scalable and automated approaches for these parties to assess the integrity of their individual components that enables one to build upon the efforts of others. In this talk, I will discuss an conceptual approach to composing system-wide integrity from enforcement of multiple system layers. This approach is motivated by various work in information flow security, but we find that managing system-wide integrity requires different inferencing approaches and care in mapping actual components to the model. In particular, we will discuss methods to establish a specifications of integrity, validating the initial integrity of system components and channels, and composing systems from such components that protect runtime integrity. We will demonstrate the use of methods on Xen and Linux systems for deploying cloud computing applications. We show that accounting for integrity in component design can lead to comprehensive system-wide management. About the speaker: Trent Jaeger is an Associate Professor in the Computer Science and Engineering Department at The Pennsylvania State University and the Co-Director of the Systems and Internet Infrastructure Security (SIIS) Lab.

P. Madhusudan, The Role of Automata Theory in Software Verification Oct 27, 2010

The 80s and 90s saw a revolution in hardware verification, where automata theory played a prominent role, formalizing model-checking and establishing the basis of verification using the logic-automata connection. We shift focus to software verification and ask how exactly would automata theory be useful in program analysis. Drawing from work in recent years in software verification in my research group as well as in the field, I will identify several key areas, ranging from modeling, abstraction, model-checking, interface synthesis, testing, to logical reasoning with dynamic data-structures, where automata theory promises to provide the right abstractions and yield effective tools for program analysis. About the speaker: Madhusudan worked for his Ph.D. at the Institute of Mathematical Sciences, India, and after a three-year post-doc stint at UPenn, joined the faculty at the Unviersity of Illinois at Urbana-Champaign. His research interests are primarily in the verification and analysis of software, with an emphasis on methods involving concurrency, logic and automata theory.

Sam King, Trust and Protection in the Illinois Browser Operating System Oct 20, 2010

Current web browsers are complex, have enormous trusted computing bases, and provide attackers with easy access to modern computer systems. In this talk we introduce the Illinois Browser Operating System (IBOS), a new operating system and a new browser that reduces the trusted computing base for web browsers. In our architecture we expose browser-level abstractions at the lowest software layer, enabling us to remove almost all traditional OS components and services from our trusted computing base by mapping browser abstractions to hardware abstractions directly. We show that this architecture is flexible enough to enable new browser security policies, can still support traditional applications, and adds little overhead to the overall browsing experience.I will also talk briefly about some of my groups recent work in defending against malicious hardware. About the speaker: Samuel T. King is an assistant professor in the Computer Science department at the University of Illinois. His research interests include security, experimental software systems, operating systems, and computer architecture. His current research focuses include defending against malicious hardware, designing and implementing secure web browsers, and applying machine learning to systems problems. Sam received his PhD in Computer Science and Engineering from the University of Michigan in 2006.

Alex Liu, Fast Regular Expression Matching using Small TCAMs for Network Intrusion Detection and Prevention Systems Oct 13, 2010

Regular expression (RegEx) matching is a core component of deep packet inspection in modern networking and security devices. Prior RegEx matching algorithms are either software-based or FPGA-based. Software-based solutions have to be implemented in customized ASIC chips to achieve high-speed, the limitations of which include high deployment cost and being hard-wired to a specific solution and thus limited ability to adapt to new RegEx matching solutions. Although FPGA-based solutions can be modified, resynthesizing and updating FPGA circuitry in a deployed system to handle RegEx updates is slow and difficult. In this talk, we present the first hardware-based RegEx matching solution that uses Ternary Content Addressable Memories (TCAMs), which are off-the-shelf chips and have been widely deployed in modern networking devices for packet classification. There are three main reasons why TCAM-based RegEx matching works well. First, a small TCAM is capable of encoding a large Deterministic Finite Automata (DFA) with carefully designed algorithms leveraging the ternary nature and first-match semantics of TCAMs. Second, TCAMs facilitate high-speed RegEx matching because TCAMs are essentially high-performance parallel lookup systems: any lookup takes constant time (i.e, a few CPU cycles) regardless of the number of occupied entries. Third, because TCAMs are off-the-shelf chips that are widely deployed in modern networking devices, it is easy to design networking devices that include our TCAM based RegEx matching solution. About the speaker: Alex X. Liu is currently an assistant professor in the Department of Computer Science and Engineering at Michigan State University. He received his Ph.D. degree in Computer Science from The University of Texas at Austin in 2006. He received the IEEE & IFIP William C. Carter Award in 2004 and the National Science Foundation CAREER Award in 2009. His special research interests are in networking, security, and privacy.

Sergey Panasyuk, Assured Processing through Obfuscation Sep 29, 2010

In this seminar, an Obfuscation Module is discussed. This module provides a means to perform computation on untrusted computing systems while maintaining the confidentiality and integrity of the information. Being able to do so not only enables assured processing, such as running a program with certain assurances that the algorithm will remain protected, but it can also increase the defensive posture of cyber systems. When an executable is requested by the operating system, the module will apply obfuscation techniques to repackage it. Once repackaged, it will send the new executable to the host system. In this way, the untrusted system will never have access to the original executable image but a convoluted equivalent of it, protecting the confidentiality of the image and the algorithm which it implements, since it is cost prohibitive to unscramble the available executable. About the speaker: Sergey Panasyuk is employed as a Computer Scientist at the Air Force Research Laboratory's Information Directorate in Rome NY. He joined AFRL in 2008 and is assigned to the Computing Architectures Branch (AFRL/RITA).

Petros Mouchtaris, Security of Mobile Ad Hoc Networks (MANETs) Sep 22, 2010

This talk will initially provide an overview of Telcordia's cyber security research. The talk will then focus on Telcordia's research in securing MANETs. MANETs are networks that do not require a fixed infrastructure (like base stations or access points) that are typically used in commercial wireless networks. In MANETs, messages are relayed from node to node from the source of a packet towards the destination. If there is a "sufficient" number of nodes covering a specific area, communication between the source and the destination can be achieved. MANETs have attracted a lot of interest in applications where fixed infrastructure may not be available or has been destroyed such as vehicle to vehicle communication, military networks, and disaster relief support. The key value of MANETs is their ability to allow nodes to join forces quickly to form a network. Achieving the potential value of MANETs in a secure manner though is a significant challenge. This talk will discuss Telcordia's research and progress in this area. About the speaker: Petros Mouchtaris is the Executive Director of Information Assurance and Security at Telcordia Technologies leading a department performing research and development of innovative cyber security technologies addressing the needs of commercial and government customers. Dr. Mouchtaris has published several papers in conferences and journals and a book entitled "Security for Wireless Ad Hoc Networks." Dr. Mouchtaris received his M.S. and Ph.D. from the California Institute of Technology.

Xiaofeng Wang, Side Channel Threats in the Software-as-a-Service Era: Challenges and Responses Sep 15, 2010

With software-as-a-service becoming mainstream, more and more applications are delivered to the client through the Web. Unlike a desktop application, a web application is a "two-part" program, with its components deployed both in the browser and in the web server. The communication between these two components inevitably leaks out the program's internal states to those eavesdropping on its web traffic, simply through the side channel features of the communication such as packet length and timing, even if the traffic is entirely encrypted. In this talk, I will present our discovery showing that such side-channel leaks are both fundamental and realistic: a set of high-profile web applications are found to disclose highly sensitive user data such as one's family incomes, health profiles, investment secrets and more through their side channels. More importantly, we found that the root causes of the problem are some fundamental characteristics of web applications: stateful communication, low entropy input for better interaction, and significant traffic distinctions. This indicates that a significant improvement of the current web-application development practice becomes necessary. As a response to this urgent call, I will also describe in this talk a new technique we developed, called Sidebuster, which facilitates detection and quantification of side-channel vulnerabilities during development of web applications. About the speaker: Dr. XiaoFeng Wang is the Director of Center for Security Informatics under the School of Informatics and Computing, Indiana University. He received his Ph.D. in Electrical and Computer Engineering from Carnegie Mellon University in August, 2004, and has since been a faculty member at IU. Dr. Wang is a recognized active researcher on system and network security, privacy protection and incentive engineering.

Xeno Kovah, Rootkits Sep 08, 2010

This talk will examine the state of current and proposed rootkits, to try and answer the following question: are rootkits stupid and lame? The speaker will provide supporting evidence that most all rootkits are eminently detectable, in theory. But theory doesn't matter if tools for detection are not used in practice. Therefore the talk will highlight the few weaknesses in detection methodologies and many weaknesses in tools, so that the audience can think about what they could do to make the world more secure. About the speaker: "Xeno Kovah is mortal and fallible. So are you."

Ashish Kundu, Data in the Cloud: Authentication Without Leaking Sep 01, 2010

Assurance of authenticity as well as confidentiality of data is an important problem, in cloud computing and in third-party data distribution environments. Existing data authentication schemes for structured and semi-structured data such as trees and graphs leak information, leading to privacy and confidentiality breaches. We have developed schemes for leakage-free authentication of trees and graphs. Our schemes are provably secure and efficient. In this talk, I would present these schemes as well as describe how to address the problem for disconnected trees/graphs (forests) (e.g., a set of databases). Time permitting, we would discuss some of the applications of these schemes. Our solutions have several applications in the cloud-based service offerings such as in the database and e-mail as services, storage and distribution of healthcare and biological data, and in security of social networks. About the speaker: Ashish Kundu is a Ph.D. Candidate in Computer Science at PurdueUniversity and is affiliated with CERIAS. Ashish is as an advisee of Prof. Elisa Bertino.

Cristina Nita-Rotaru, Secure Network Coding for Wireless Mesh Networks Aug 25, 2010

In this talk we identify two general frameworks (inter-flow and intra-flow) that encompassseveral network coding-based systems proposed in wireless mesh networks. Our systematicanalysis of the components of these frameworks reveals vulnerabilities to a wide range of attacks,which may severely degrade system performance. We then focus on addressing the most severeand generic attack against network coding systems, known as packet pollution attack. We showthat existing cryptographic mechanisms that were proposed to solve the problem have a prohibitivecost that makes them impractical in wireless mesh networks. We propose the first practical defensemechanisms to pollution attacks in network coding for wireless mesh networks. The experimentalresults show that the proposed mechanisms can effectively filter out polluted packets and quicklyidentify and isolate attacker nodes while incurring small computation and bandwidth overhead.

Christian Hammer, Security of JavaScript in a Browser Environment Apr 14, 2010

The power of modern websites emerges to a large extent from the ability to combine content from different sources. As an example, a site may include a Google map next to business information a user had been searching for. Combining content from possibly untrusted sites gives rise to all sorts of security concerns, as JavaScript has no concept of separating scripts from different sources. This has lead to several recent attacks like the Samy or Yamanner worms. This talk presents the state of the art in securing JavaScript for such settings and proposes a sandboxing facility for in-browser script separation. About the speaker: Christian Hammer is a post-doctoral researcher at Purdue University working in the Secure Software Systems lab with Prof. Jan Vitek. His research interests include static and dynamic program analyses, in particular security, program slicing, information flow, concurrency, and programming languages. He received the Doctor of Engineering (Dr.-Ing.) from Karlsruhe Institute of Technology, Germany in 2009, and a Diplom (equiv. M.Sc.) in Computer Science from University of Passau, Germany. As a graduate student, he spent two semester breaks at the IBM T. J. Watson Research Center in Hawthorn, NY.

Yvo Desmedt, 60 years of scientific research in cryptography: a reflection Apr 07, 2010

Shannon started the unclassified scientific research in cryptography with hisOctober 1949 paper. First we briefly survey the scientific research incryptography since then. We discuss the strengths and weaknesses of thisresearch, attempting to present a balanced viewpoint.The lecture will also discuss the progress we have not made. We will show thatnot everything in modern cryptography is rosy.

David Bell, Everything I Needed to Know about Security, I Learned in 1974 Mar 31, 2010

The security field is an excellent illustration of the maxim that ``the more things change, the more they stay the same.'' Thus while technical details change, underlying security principles remain remarkably constant. Dr. Bell's talk ``Everything I Needed to Know about Security, I Learned in 1974'' covers the lessons he learned in his early modeling work, how they have remained valid since, and how those principles inform his view of 21st-Century challenges. About the speaker: David Elliott Bell, Ph. D., is the co-author of the widely-known ``Bell-La Padula security model." His work in security has been varied, from the conceptual security of his modeling work to security architectures, operating system security, database management security, network security, formal verification, public-key technology, and standards and guidelines for security practice.In addition to security, he has also contributed in systems design and implementation, acquisition, integration, and, not least, in passing his insight along through formal and informal training and education. He has been a guest lecturer at the U.S. Military Academy at West Point and the U.S. Naval Academy at Annapolis.Major customers benefitting from his contributions include the Department of Defense, especially the U.S. Air Force, DIA, and the National Security Agency (where he was presented the NSA Meritorious Civilian Service Award); the Department of Homeland Security; and the Department of Energy.Since retirement, he has given invited addresses at ACSAC, Mississippi State University, the University of Nebraska, Omaha, and Winston-Salem State University.

David Zage, A Platform for Creating Efficient, Robust, and Resilient Peer-to-Peer Systems Mar 24, 2010

The rapid growth of communication environments such as the Internet has spurred the development of a wide range of systems and applications based on peer-to-peer ideologies. As these applications continue to evolve, there is an increasing effort towards improving their overall performance. This effort has led to the incorporation of measurement-based adaptivity mechanisms and network awareness into peer-to-peer applications, which can greatly increase peer-to-peer performance and dependability. Unfortunately, these mechanisms are often vulnerable to attack, making the entiresolution less suitable for real-world deployment. In this work, we study how to create robust systems components for adaptivity, network awareness, and responding to identified threats. These components can form the basis for creating efficient, high-performance, and resilient peer-to-peer systems.

Wonjun Lee, Detection and protection from denial of service attacks in grids by accountability agents Mar 03, 2010

By exploiting existing vulnerabilities, malicious parties can take advantage of resources made available by grid systems to attack mission critical websites or the grid itself. In this paper, we present two approaches for protecting against attacks aiming at targets located outside or inside the grid. Our approach is based on special-purpose software agents, referred to as accountability agents that collect provenance and resource usage data in order to perform detection and protection. We show the effectiveness of our approach and the performance of the accountability agent based system by conducting various experiments on a grid-emulated testbed. About the speaker: I am a Ph.D candidate at School of Electrical & Computer Engineering. My research interests are in security issues related to authentication, authorization, accountability, and identity management in distributed computing systems such as grid, cloud. Currently I am working on the distributed denial of service attacks induced from grid resources, and the accountability policies. My research advisor is Professor Elisa Bertino in Computer Science. I am originally from South Korea.

Kevin Hoffman, Ribbons, A Partially-Shared Memory Programming Model Feb 24, 2010

We present ribbons, a shared memory programming modelthat allows for more implicit sharing of memory than processes but ismore restrictive than threads. Ribbons structure the heap into protectiondomains. Privileges between these protection domains are carefullycontrolled to provide the ability to fully or partially "sandbox" certainportions of a program's computation. RibbonJ, a backwards-compatibleextension of Java, is deﬁned to easily create programs that leverage theribbons model. RibbonJ is implemented within Jikes RVM, and avoidsthe overhead of inline security checks and read or write barriers byleveraging the memory protection mechanisms already supported inmodern hardware and operating systems. This is joint work withHarrison Metzger and Professor Patrick Eugster. About the speaker: Kevin Hoffman is a PhD candidate in the Computer Science Department at Purdue, advised by Professor Patrick Eugster.He has published papers on topics ranging from reputation systems,aspect-oriented programming, and software metrics, to automatedregression-cause determination via dynamic software analysis.He is currently working on the Ribbon project, as well as onscalable, low-latency, low-contention garbage collection techniquesfor high core count systems.

Hyo-Sang Lim, Provenance-based Data Trustworthiness Assessment in Data Streams Feb 17, 2010

This talk presents a systematic approach for estimating the trustworthiness of data items in data stream environments (such as sensor networks). The approach uses the data item provenance as well as their values. To obtain trust scores, the approach exploits a cyclic framework which well reflects the inter-dependency property: the trust scores of data items affect the trust scores of network nodes, and vice versa. The trust scores of data items are computed from their value similarity and provenance similarity. The value similarity comes from the principle that "the more similar values for the same event, the higher the trust scores," and we compute it under the assumption of normal distribution. The provenance similarity is based on the principle that "the more different provenances with similar values, the higher the trust scores," and we compute it using the tree similarity. Since new data items continuously arrive in DSMSs, we need to evolve (i.e., recompute) trust scores to reflect those new items. As evolution scheme, we propose the batch mode for computing scores (non)periodically along with the immediate mode. Experimental results show that the approach is efficient and effective in data stream environments. About the speaker: Hyo-Sang Lim is a post-doc in the department of computer science and CERIAS at Purdue University. He received his B.S. degree in computer science from Yousei University, South Korea and M.S. and Ph.D. degrees in computer science from KAIST (Korea Advanced Institute of Science and Technology).

Marcus Rogers, Dissecting Digital Data: Context & Meaning through Analytics Feb 10, 2010

This talk will look at how analytics can be used to increase our understanding of what digital evidence actually means. The real value of evidence is often related to the context and meaning of the data ; not just on its mere existence. The talk will examine how analytics can be used to answer core investigative and intelligence questions and where meaning can be found.

Greg Stephens, Detecting Insider Theft of Trade Secrets Feb 03, 2010

Trusted insiders who misuse their privileges to gather and steal sensitive information represent a potent threat to businesses. Applying access controls to protect sensitive information can reduce the threat but has significant limitations. Even if access controls are set properly, they don't protect against rogue employees who legitimately need to access sensitive information. Since 2002, researchers at MITRE have investigated methods for detecting insiders who misuse their legitimate access to steal information. A three-year, internally funded research effort developed and evaluated a research prototype of a system called Elicit (Exploit Latent Information to Counter Insider Threats) to help analysts identify insider threats. Work on Elicit prompted a team of engineers and social scientists to experimentally explore how malicious insiders use information differently from a benign baseline group. This talk presents results from the research prototype evaluation, discusses preliminary results from the double-blind study of malicious insiders, and offers some essential aspects for detecting insider threats gleaned from these efforts. About the speaker: Since joining MITRE in 2001, Greg has been consulting and researching in the area of enterprise security operations. His areas of expertise include security operation center (SOC) architecture and management, the effective implementation of intrusion detection and audit systems, and the effective use of security information management systems (SIMs). Since 2003, his focus has been on detecting insider threats. He led successful R&D efforts within MITRE and for the Institute for Information Infrastructure Protection (I3P) that yielded an effective, novel detection approach and significant insight into insider threat behavior. He is currently extending his insider threat research, adapting it for cyber threat detection. Prior to joining MITRE, Greg helped architect the managed security monitoring service provided by Counterpane Internet Security and managed the security of a mid-sized defense contractor.Greg holds a B.S. in Materials Science from U.C. Berkeley and an M.S. in Information Technology from George Mason University.

Kelly Caine, Human Factors Approaches to Preserving Privacy Dec 09, 2009

Threats to privacy are not only due to traditional computer security issues; human factors issues such as unintentional disclosure of information also have an impact on privacy preservation. In this talk I will discuss two examinations of psychological aspects of privacy and how they relate to technology. First, I will present results from an investigation of everyday privacy behaviors and discuss how these naturally occurring behaviors can guide the design of privacy protective technology. Then, I will introduce the concept of misclosure, which is the unintentional disclosure of information, and provide multiple example misclosures. I will conclude by demonstrating that misclosures a) occur frequently b) occur across systems and c) may be preventable by considering human factors during design. About the speaker: Kelly Caine is a Research Fellow in the School of Informatics and Computer Science at Indiana University. She received her B.A. in Psychology from the University of South Carolina and her M.S. and Ph.D. in Engineering Psychology from the Georgia Institute of Technology.

Gerome Miklau, Safely Analyzing Sensitive Network Data Nov 18, 2009

Social and communication networks are formed by entities (such as individuals or computer hosts) and their connections (which may be contacts, relationships, or flows of information). Such networks are analyzed to understand the influence of individuals in organizations, the transmission of disease in communities, the operation of computer networks, among many other topics. While network data can now be recorded at unprecedented scale, releasing it can result in unacceptable disclosures about participants and their relationships. As a result, privacy concerns are severely constraining the dissemination of network data and disrupting the emerging field of network science. Our recent work investigates the properties of a network that can be accurately studied without threatening the privacy of individuals and their connections. We adopt the rigorous condition of differential privacy, and develop algorithms for releasing randomly perturbed statistics about the topology of a sensitive network. This talk will focus on two basic analysis tasks: the estimation of the degree distribution of a network and the study of small structural patterns that occur in a network (sometimes called motif analysis). We show that the degree distribution of a network can be very accurately estimated by a novel technique in which constraints are applied to the noisy output to improve utility. This technique is of general interest, and can be used to boost the accuracy of differentially private output in other tasks as well. We show that studying motifs is fundamentally harder, but can be done with acceptable accuracy if the privacy condition is relaxed. About the speaker: Gerome Miklau is an Assistant Professor at the University of Massachusetts, Amherst. His primary research interest is the secure management of large-scale data. This includes evaluating threats to privacy in published data, devising techniques for the safe publication of social networks, network traces, and audit logs, designing database management systems to implement security policies, and theoretically analyzing information disclosure.

Leszek Lilien, Some Thoughts on the Pervasive Trust Foundation for the Future Internet Architecture. A position presentation. Nov 11, 2009

We start with presenting motivation and goals for the Future Internet, and reviewing basics of trust in computing.The Pervasive Trust Foundation (PTF) for the Future Internet is proposed next. This includes presenting motivation for trust foundation for the Future Internet, showing placement of security services and mechanisms within the architecture, and trust considerations for security services.Inefficient operation of the PTF-based architecture is the main obstacle to making such architecture a reality. There are two classes of approaches that can reduce operational costs. First, inherent PTF properties result in automatic cost-saving. Second, additional cost-saving techniques --such as leveraging high-trust enclaves, or using enclave "insurers"-- can be used.The architectural principles presented here are a position statement, and their practical verification will require substantial research efforts. About the speaker: Leszek Lilien is an Assistant Professor of Computer Science at Western Michigan University (WMU). He obtained his Ph.D. degree from the University of Pittsburgh, and was involved in post-doctoral research at Purdue University.

Zahid Pervaiz, Multi-Policy Access Control for Healthcare using Policy Machine Nov 04, 2009

Access control policies in healthcare domain define permissions for users to access different medical records. A Role Based Access Control (RBAC) mechanism allows management of privileges to medical records for users when they assume certain roles thus mitigating the threat of inside attacks. Such a threat emanates from unauthorized users. We can provide a selective combination of policies where sensitive records can be available only to a specific role, say the primary doctor, under Discretionary Access Control (DAC) whereby in turn he/she may share the record with other physicians for consultation after permission from the patient. This mechanism allows not only a better compliance of principle of least privilege but also helps to mitigate the threat of authorized insiders disclosing sensitive information. Our research is being prototyped on the Policy Machine (PM) developed by the National Institute of Standards and Technology (NIST). PM allows integration and co-existence of multiple policies. Currently, we are expanding thecapabilities of PM to provide a flexible healthcare access control policy which has the benefits of context awareness and discretionary access. We will present the newlyimplemented temporal RBAC model on PM and describe initial capabilities for secure management of healthcare data. About the speaker: Zahid Pervaiz is a PhD candidate in School of Electrical and Computer Engineering at Purdue University. He received his bachelor's degree in Electronics engineering from National University of Science and Technology, Pakistan in 2000.

Andre Koenig, Security in Infrastructureless and Decentralized Communication Networks - Possibilities, Results, and Evaluation Challenges Oct 28, 2009

Infrastructureless and decentralized communication substrates such as mobile ad hoc networks and peer-to-peer systems enable setting up communication services beyond borders of contemporary wired or cellular client/server systems. Yet, due to their specific characteristics like wireless multihop data transmission and lack of central trusted instances, infrastructureless and decentralized networks are also beyond the protection of contemporary security mechanisms. This especially requires consideration in possible first responder or military application scenarios. Various new threats targeting each layer of the ISO/OSI model have been identified. Central questions regarding security include how to deal with misbehavior and how to protect information in networks without well-defined borders, consisting of devices, services, and users from multiple administrative domains.In this talk we present possible solutions for excluding misbehaving nodes from infrastructureless networks to recover the availability of the network in presence of attacks. We further present mathematical tools for governing cooperative decision processes without central trusted instances as basis for security objectives such as authentication and access control in decentralized systems. We show evaluation results based on analytical models as well as simulation and testbed studies and highlight general challenges regarding the evaluation of protocols and algorithms for infrastructureless decentralized communication networks. About the speaker: Andre Koenig received his diploma in computer science from TU Darmstadt. After having worked for a system retailer offering network design, consultation, and trainings, he joined the Multimedia Communications Lab (KOM) at TU Darmstadt, Germany, in 2005.

Juhee Kwon, Information Security Management and IT Executives in a Top Management Team Oct 21, 2009

As information assets have become a critical factor for enterprises to stay competitive, there is an increasing awareness of information security management. However, they are easily overlooked by those who focus only on the IT side, failing to see that human resources and policies are the most likely cause of information risks, which need to become real enterprise-wide and strategic issues. This paper examines the impacts of an IT executive's structural status in Top Management Teams (TMTs) on information security risk management. E-Business has made it imperative for IT executives to adopt cross-functional roles due to the increased importance of securing and managing risks to information assets across the enterprise. Therefore, IT executive representation and status in a TMT is necessary to strategically and operationally conduct liaison activities between IT groups and other business units. However, there is little empirical research examining the effects of IT executives' structural status on managing information security risks. We employ logistical regression to examine the data from 2003 to 2008 with information security breach reports and executive compensation data. We augment this data with IT internal controls information provided by external auditors. Our results demonstrate high IT executive engagement and fair compensation are associated with reduced levels of both IT internal controls weaknesses and reported information security breaches. Second, we find that pay dispersion in a TMT increases the probability of information security breaches, while IT executive turnover is not significantly associated with breaches. As a comprehensive analysis across the accounting, human resources, and information systems literature, this study gives firms new insights into how they set IT executive compensation strategies as well as delegate authority and responsibility for ensuring confidentiality, integrity, and availability of information assets. About the speaker: Juhee Kwon is currently a Ph.D. candidate of Management Information Systems at Krannert School of Management, Purdue University. Her primary research interests cover Information Security and Privacy. Although the primary interest is in information security, her research interest spans e-Commerce, Accounting Information Systems, and Telecommunication with cross-selling.

Raquel Hill, PlugNPlay Trust for Embedded Communication Systems Oct 14, 2009

Given the proliferation of malware, the integrity of embedded communication systems is becoming a growing concern. Recent compromises to systems such as ATMs and network switches and routers provide evidence of the potential security problems of embedded communication systems. Trusted communication channels that pass sensitive information should only be established after the integrity of the remote system can be assured. Security hardware, such as the Trusted Computing Group's (TCG's) Trusted Platform Module (TPM) provides a mechanism to measure and authenticate the integrity of individual machines. This device can be readily found in many laptops today, however we are unaware of its use as a mechanism for providing or denying communication access to services based on the integrity of remote systems. In this work, we propose PlugNPlay Trust, an integrity framework which is a drop-in solution for providing a hardware root of trust for embedded applications. The PlugNPlay Trust design exploits the static nature of embedded communication systems and independently provides remote attestation and identity verification for the host application using the TPM. This framework, coupled with the attestation and dynamic firewall exception services we authored, enables remote parties to confirm the integrity of embedded communication systems, thereby limiting the effects and the proliferation of malware in compromised systems. Although there are preexisting technologies for interfacing with the TPM directly, we implemented the first prototype for allowing or denying access to networked services based on the trustworthiness of a remote system. The PlugNPlay framework simplifies the integration of existing TPM related tools and provides a ready to use platform for trusted computing research. About the speaker: Raquel Hill is an Assistant Professor of Computer Science in the School of Informatics and Computing. Her primary research interests are in the areas of trust and security for distributed and pervasive computing environments. Dr. Hill's research is funded by the Center for Applied CyberSecurity Research (CACR). She holds B.S. and M.S. degrees in Computer Science from Georgia Tech and a Ph.D. in Computer Science from Harvard University.

Gary McGraw, Building Security In Maturity Model (BSIMM) Oct 07, 2009

As a discipline, software security has made great progress over the last decade. There are now at least 46 large scale software security initiatives underway in enterprises including global financial services firms, independent software vendors, defense organizations, and other verticals. In 2008, Brian Chess, Sammy Migues and I interviewed the executives running nine initiatives using the twelve practices of the Software Security Framework as our guide. Those companies among the nine who graciously agreed to be identified include: Adobe, The Depository Trust and Clearing Corporation (DTCC), EMC, Google, Microsoft, QUALCOMM, and Wells Fargo. The resulting data, drawn from real programs at different levels of maturity was used to guide the construction of the Building Security In Maturity Model (BSIMM). This talk will describe the observation-based maturity model, drawing examples from many real software security programs. A maturity model is appropriate because improving software security almost always means changing the way an organization works---people, process, and automation are all required. While not all organizations need to achieve the same security goals, all successful large scale software security initiatives share common ideas and approaches. Whether you rely on the Cigital Touchpoints, Microsoft's SDL, or OWASP CLASP, there is much to learn from practical experience. Since its March release, the BSIMM is being expanded to include BSIMM Europe, BSIMM II, and BSIMM Lite. Use the BSIMM as a yardstick to determine where you stand and what kind of software security plan will work best for you.

Richard Power, Starting Over After A Lost Decade, In Search of a Bold New Vision for Cyber Security Sep 30, 2009

Starting Over After A Lost Decade, In Search of a Bold New Vision for Cyber Security: It is not enough to develop a comprehensive cyber security program that exists in isolation from the world beyond the cloud and the cables. We have to understand the political, economic and social environments that impact our ability to deliver security, as well as our own organizational cultures. We cannot wage a 21st Century struggle for hearts and minds with a 20th Century world-view anymore than we can wage a 21st Century struggle to secure information and systems with 20th Century technology. A bold new vision is needed, one that is holistic and evolves out of transformative metaphors that reframe our concepts about security. About the speaker: Richard Power, an internationally recognized authority on Security, Intelligence and Risk, has conducted executive briefings and led professional training in over forty countries, and been widely quoted in the world news media.

Rick Aldrich, The Importance of Law in Cybersecurity, Recent Developments and Trends in Cyberlaw Sep 23, 2009

Information security professionals increasingly need to be familiar with developments in cyberlaw to ensure they comport their actions with the contours of the law. Unfortunately, with technology changing far faster than the statutes, judges are increasingly being called upon to fill in the interstices. In this interactive session, facts from actual cases will be presented in a "You Be the Judge" format to highlight important developments in recent cases and identify key trends in the case law. What is the legal efficacy of a click-through consent banner and how does this impact information security professionals? What constitutes an "interception" and what types of interceptions are legal and illegal? What law dictates whether an employer can or cannot inspect its employee's personal e-mail messages? Do individuals have to divulge their encryption keys requested to do so by border guards or law enforcement agents? Are there jurisdictional borders in cyberspace? Who has jurisdiction and how does the law apply in virtual worlds? How do extradition laws apply to cybercrimes? These and many other questions will be answered in this interactive seminar. About the speaker: Rick Aldrich is the Senior Computer Network Operations Policy Analyst for the Information Assurance Technology Analysis Center and an Associate for Booz Allen Hamilton.

Peter Mork, Database Assurance: Anomaly Detection for Relational Databases Sep 09, 2009

Behind countless complex applications lurk trusty relational databases that are responsible for managing the data that fuel these applications. For example, relational databases are used to support electronic medical health record systems, timecard reporting systems, and transportation systems. Ideally, the relational database system has been sufficiently hardened to prevent exfiltration or modification of data. Unfortunately, adversaries often have insider access to the networks and machines on which the database is running and can easily circumvent such security measures. Therefore, in this research project, we create profiles of known, legitimate behavior so that we can flag any anomalous behavior as potentially illegitimate.In this presentation, because SQL injection remains the #1 attack vector, I will first illustrate how SQL injection attacks can exfiltrate data from a database system. I will then discuss various locations within the database engine that one might monitor activity, highlighting the benefits of placing a monitor between the query optimizer and query execution engine. Next, I will describe how we use cross-feature analysis to generate profiles of legitimate behavior and how these profile are used at run-time to identify anomalous activity. Then, I will present experimental results both in terms of performance overhead and precision/recall. I will conclude with a discussion of when our techniques are most applicable and how a clever adversary might nevertheless elude our monitor.

Ragib Hasan, Fake Picassos, Tampered History, and Digital Forgery: Protecting the Genealogy of Bits with Secure Provenance Sep 02, 2009

As increasing amounts of valuable information are produced and persistdigitally, the ability to determine the origin of data becomesimportant. In science, medicine, commerce, and government, dataprovenance tracking is essential for rights protection, regulatorycompliance, management of intelligence and medical data, andauthentication of information as it flows through workplace tasks.While significant research has been conducted in this area, theassociated security and privacy issues have not been explored, leavingprovenance information vulnerable to illicit alteration as it passesthrough untrusted environments.In this talk, we show how to provide strong integrity andconfidentiality assurances for data provenance information in anuntrusted distributed environment. We describe our provenance-awaresystem prototype that implements provenance tracking of data writes atthe application layer, which makes it extremely easy to deploy. Wepresent empirical results that show that, for typical real-lifeworkloads, the run-time overhead of our approach to recordingprovenance with confidentiality and integrity guarantees ranges from1% - 13%.For more details, please refer to http://dais.cs.uiuc.edu/provenance About the speaker: Ragib Hasan is a Ph.D. candidate at the Department of ComputerScience, University of Illinois at Urbana-Champaign, working withProf. Marianne Winslett.

Ian Goldberg, Sphinx: A Compact and Provably Secure Mix Format Aug 26, 2009

Mix networks, originally proposed in 1981, provide a way for Internetusers to send messages--such as email, blog posts, or tweets--withoutautomatically revealing their identities or their locations. In thistalk, we will describe Sphinx, a cryptographic message format used torelay anonymized messages within a mix network. It is the first schemeto support a full set of security features: compactness, efficiency,provable security, indistinguishable replies, hiding the path length andrelay position, as well as providing unlinkability for each leg of themessage's journey over the network. We will compare Sphinx to other mixformats, and will also briefly outline Sphinx's security reductionproof.

John D'Arcy, User Awareness of Security Countermeasures and its Impact on Information Systems Misuse: A Deterrence Approach Apr 15, 2009

Intentional insider misuse of information systems resources (i.e., IS misuse) represents a significant threat to organizations. For example, industry statistics suggest that between 50-75% of security incidents originate from within an organization. Because of the large number of misuse incidents, it has become important to understand how to reduce such behavior. General deterrence theory suggests that certain controls can serve as deterrent mechanisms by increasing the perceived threat of punishment for IS misuse. This study presents an extended deterrence theory model that combines work from criminology, social psychology, and information systems. The model posits that user awareness of security countermeasures directly influences the perceived certainty and severity of organizational sanctions associated with IS misuse, which leads to reduced IS misuse intention. The model is then tested on 269 computer users from eight different companies. The results suggest that three practices deter IS misuse: user awareness of security policies; security education, training, and awareness (SETA) programs; and computer monitoring. The results also suggest that perceived severity of sanctions is more effective in reducing IS misuse than certainty of sanctions. Further, there is evidence that the impact of sanction perceptions vary based on one's level of morality. The results have implications for both the research and practice of IS security.

Johann-Christoph Freytag, Privacy – from accessing databases to location based services Apr 08, 2009

Over the last years it has become apparent that privacy issues become moreand more important when accessing data sources either on the Web or bydatabase management systems. That is, the user does not only want to hidethe query, but also the result of that query from others. In the past theproblem of querying a database privately was solved by organizational ratherthan by technical means.In this talk we describe the problem of querying databases privately moreformally and discuss existing solutions from the area of private informationretrieval (PIR). The lack of efficiency and scalability motivated us lookfor alternative approaches using a so called "secure co-processor" (built byIBM). We introduce a set of algorithms that take advantage of the (physical)properties of the co-processor and show which algorithms are necessary toguarantee privacy for database queries. In the last part of my talk Ibriefly describe our vision how to extend the current privacy approach tolocation-based services, in particular to moving objects such as vehicles(cars). About the speaker: Johann-Christoph Freytag is a full professor for databases and informationsystems (DBIS) at the Computer Science Department of theHumboldt-Universität zu Berlin, Germany.

Melissa Dark, An Analysis of Data Breach Disclosure Apr 01, 2009

In the past six years, 44 states in the United States have embraced a new form of privacy and identity theft regulation – mandatory disclosure of data breach information. Information disclosure regulation is a form of legislation considered effective for issues that span consumer protection and risk and where market mechanisms would/could work effectively to shape consumer and producer behavior and bring about allocative efficiency. Informational regulation is a new approach in the data privacy milieu, but has a precedent in environmental and health policy. While data breach information disclosure policies intend to have an impact on consumer and producer behavior, little is known about the costs and benefits of these policies and whether they are in fact enhancing social welfare in the area of identity theft and privacy. This talk addresses this relatively nascent public policy phenomenon with a focus on future considerations for policy analysis in this area to determine if and how such policy may be affecting the state of information assurance and security in the USA. About the speaker: Melissa Dark is a Professor in computer and information Technology. She has been working in information assurance and security education for almost 10 years. Roughly two years ago she became interested in the effects of public policy on user behavior, where users include individuals, organizations, and nations. She is currently on fellowship to study public policy and welfare economics with the goal of applying these approaches and tools to the field of information assurance and security.

Jeremy Rasmussen, The Best Defense is Information Mar 04, 2009

In the course of doing security vulnerability testing for government and commercial clients over the past 10 years, our Information Security Solutions team at Sypris Electronics has seen a lot of interesting things—perhaps none more so than a recent attack witnessed on a client's network targeted by a buffer overflow on a popular application. The attack launched a trojan horse, which then dropped in another piece of malware that stealthily connected out to several sites to receive command and control. We will go down the rabbit hole with the attack (as much as I can publicly divulge), talk about our approach to the forensic investigation, and how the client was advised to implement countermeasures to provide an overall framework of security against future attacks.It is possible people may have known about this particular exploit for more than six months before it was publicly disclosed, and the vendor still has not published a patch for it. Therefore, in this talk, we will also explore the concept of responsible disclosure, information sharing (minus attribution), and how all of this possibly fits into the Presidential Comprehensive National Cybersecurity Initiative (CNCI). About the speaker: Jeremy Rasmussen is manager of the Information Security Solutions (ISS) group at Sypris Electronics, LLC in Tampa Florida. Sypris is an industry leader with more than 40 years of success in complex electronics manufacturing and engineering products and services for defense and aerospace.

Mummoorthy Murugesan, Providing Privacy through Plausibly Deniable Search Feb 25, 2009

Query-based web search is becoming an integral part of many people's daily activities. Most do not realize that their search history can be used to identify them (and their interests). In July 2006, AOL released an anonymized search query log of some 600K randomly selected users. While valuable as a research tool, the anonymization was insufficient: individuals could be identified from the contentsof the queries alone Government requests for such logs serves to increase the concern. To address this problem, we propose a client-centered approach of "plausibly deniable search". Each user query is substituted with a standard, closely-related query intended to fetch the desired results. In addition, a set of k-1 cover queries are issued; these have characteristics similar to the standard query but on unrelated topics. The system provides a property that any of these k queries will produce the same of set of k queries, giving k possible topics the user could have been searching for. We use Latent Semantic Indexing (LSI) based technique to generate queries, and evaluate on the DMOZ webpage collection to show the effectiveness of the proposed approach.

Charles Killian, Mace: Systems and Language Support for Building Correct, High-Performance Networked Services Feb 18, 2009

Building distributed systems is particularly difficult because of theasynchronous, heterogeneous, and failure-prone environment where thesesystems must run. This asynchrony makes verifying the correctness ofsystems implementations even more challenging. Tools for buildingdistributed systems must strike a compromise between reducing programmereffort and increasing system efficiency. Mace is a C++ languageextension, compiler, runtime, and toolset, that translates a concise butexpressive distributed system specification into a C++ implementation.Mace exploits a natural decomposition of distributed systems into alayered, event-driven state machine. A key design principle of Mace isto separate each service algorithm from the implementation mechanics(serialization, dispatch, synchronization, etc.), debugging code (loggingand property testing), and its utility services (lower-level servicesproviding a specified interface). Our experience indicates thatprecisely because Mace imposes limits on the design structure ofdistributed systems, it supports the implementation of a wide variety ofhigh-level supporting tools, including model checking, simulation, livedebugging, and visualization. Mace is fully operational, has been indevelopment for four years, and has been used to build a wide variety ofInternet-ready distributed systems. This talk will describe both theMace programming language design and MaceMC, the first model checkerthat can find liveness violations in unmodified systems implementations.

Mehmet Sahinoglu, Quantitative Risk Assessment of Software Security and Privacy, and Risk Management with Game Theory Feb 11, 2009

The need for information security is undeniable and self-evident. The pervasiveness of this critical topic requires primarily risk assessment and management through quantitative means. To conduct an assessment; repeated security probes, surveys, and input data measurements must be taken and verified toward the goal of risk mitigation with minimal cost. One can evaluate risk using a probabilistically accurate statistical estimation scheme in a quantitative security meter (SM) model that mimics the events of the breach of security. An empirical study using Java code is presented and its accuracy is veriﬁed by discrete-event or Monte Carlo simulations. The design improves as more data are collected and updated. Practical aspects of the SM are presented with a real-world example as related to a PC user and a risk-management scenario using the Game Theory approach for optimal cost mitigation results.

Cassio Goldschmidt, The Dark Side of Software Engineering and How to Defend Against It Feb 04, 2009

If you create an application that runs on one or more computersconnected to a network such as the internet, your code will be attacked.Consequences of compromised systems often include loss of trust,reputation and revenue. Software will always have defects andvulnerabilities. Strikes against digital assets are unquestionably onthe rise. We can, however, make it substantially harder to find andexploit vulnerabilities by identifying insecure coding practices and developing secure alternatives.During this practical session, we'll examine in detail the principlesbehind some of the worst attack patterns seen today in the softwareindustry. Most importantly, we'll learn effective defense programmingtechniques every developer must employ when building software.

Ryan Riley, An Alternate Memory Architecture for Code Injection Prevention Jan 28, 2009

Code injection attacks, in their various forms, have been in existence and been an area of consistent research for a number of years. A code injection attack is a method whereby an attacker inserts malicious code into a running computing system and transfers execution to his malicious code. In this way he can gain control of a running process or operating system due to the fact that his injected code will run at the same privilege level as the entity being attacked. At the user-level, these attacks can be used to gain access to a system through an application bug. At the kernel-level, they are commonly used to install kernel rootkits and hide an attacker's presence on a machine.In this talk I will discuss code injection with regards to the memory architecture of modern computer systems. I will compare two common memory architectures, von Neumann and Harvard, with respect to their susceptibility to code injection attacks and the advantages and disadvantages of each in practice. Based on this, I will present a third memory architecture which is immune to code injection attacks and describe implementations of it that are able to stop code injection at the user and kernel levels. My experimental results show that this architecture is able to effectively and efficiently prevent code injection attacks against unmodified operating systems and applications running on standard x86 hardware. About the speaker: Ryan Riley is a doctoral candidate and research assistant at Purdue University in West Lafayette, IN. His research interests include Operating System and Network Security, Intrusion Detection and Prevention, Virtualization Technology, Distributed Systems, and Cloud Computing .

He is preparing to graduate with his Ph.D. In Computer Science in August 2009 and is hoping to enter academia.

Paul Kidwell, A Rules Based Statistical Algorithm for Keystroke Detection Jan 21, 2009

A rules-based statistical algorithm (RBSA) identifies packets in any TCP connection that are client keystrokes of an ssh login. The input data of the algorithm are the packet arrival times and TCP/IP headers of the connection packets at a point along the path of the connection.The algorithm is applied to all connections seen by a network monitor; ssh port 22 connections are classified as client-keystrokes or scp file transfers, and ssh keystroke connections are discovered for all otherports. This forms a network login database that can be further analyzed for network security monitoring and forensics. One application is to an "inside'' network in which the monitor sees all connections betweenthe inside and outside.The model --- which uses the packet sizes, flags, and interarrival times --- first goes through the packets identifying epochs of different activities, and then goes back and uses more detailed information forthe classification. Performance from three types of packet traces is excellent.Previous work has proceeded by forming connection summary statistics from the headers and timestamps, and classifying the connection as one with keystrokes or not using the statistics. The RBSA takes on a muchmore ambitious task of classifying each packet as a client keystroke packet or not, but in the end the classification of the connection has extremely low false positives and false negatives.One important property of the RBSA is that it does not employ packet payload, as is done in some connection-level surveillance methods, so itcannot be defeated by an attacker through payload encryption. A second important property is that the inside network can be a large enterprise,allowing monitoring and forensics across a very large number of hosts from a single device."

Chris Clifton, Measuring Privacy: A Risk-Based Approach Jan 14, 2009

There have been significant research developments in technology to protect privacy. Unfortunately, few of these have made the transition to practice. A large part of the problem is the lack of an accepted way to measure privacy. Legal and regulatory terms do not translate well into technological solutions, and the plethora of technical approaches do not seem to resonate with privacy advocates.This talk will discuss issues and challenges, with examples of the reason why a clear standard is difficult. A risk-based approach will be presented that allows anonymization based on controlling the potential damage from disclosure. This approach will be compared with more traditional anonymization measures, showing the difficulty of measuringthe potential for harm from those measures.This represents joint work with Mehmet Ercan Nergiz (Purdue University) and Maurizio Atzori (University of Pisa).

Ibrahim Baggili, Extending anonymity research to high-tech white collar crimes and IT Insider threat: A critical step Dec 10, 2008

Theories of deindividuation share common grounds, one of which is anonymity. For decades, it has been hypothesized that anonymity affects human behavior. With the rise of the popularity and development of personal computing, claims are made that individuals perceive themselves to be more anonymous in computer mediated environments. This perception may be a major factor contributing to the engagement of individuals in online antisocial behaviors and in cyber criminal activities like high-tech white collar crimes and Information Technology (IT) insider threat crimes. This talk presents an overview of the literature on anonymity and the deindividuation theory. A philosophical bind is then made between the various effects of anonymity, high-tech white collar crimes and IT insider threat crimes. These philosophical accounts may be used as a cornerstone for scientific research in the new cyber crime phenomenon. About the speaker: Ibrahim Baggili is a doctoral candidate and graduate lecturer at Purdue University, West Lafayette, Indiana, in the department of Computer and Information Technology. His research interests include cyber forensics from a technical social and psychological perspectives and finding ways of improving the scientific validity of the field. His major current research initiative focuses on the effect of anonymity and integrity on cyber crime related activities. He can be reached at baggili@purdue.edu.

Weidong Cui, Automatic Signature Generation for Unknown Vulnerabilities Dec 03, 2008

In this talk, I will present a new approach to automatically generate a vulnerability signature for an unknown vulnerability, given a zero-day attack instance. Our approach is based on two systems we developed: Tupni and ShieldGen.Tupni takes one or more input instances and reverse engineers their format by analyzing how an application parses and processes them. Its reverse-engineered format has a rich set of information, including record sequences, record types and input constraints. We have implemented a prototype of Tupni and demonstrated that it can effectively reverse engineer ten common, real-world file and network message formats.ShieldGen can generate a vulnerability signature for an unknown vulnerability, given a zero-day attack instance and its format. The key novelty of ShieldGen is that it leverages knowledge of the input format to generate new potential attack instances, uses a zero-day detector as an oracle to determine if an instance can still exploit the vulnerability, and then takes the feedback of the oracle to guide its search for the vulnerability signature. We have implemented a prototype of ShieldGen and used it to generate high-quality vulnerability signatures for three real-world vulnerabilities.By feeding the input format generated by Tupni to ShieldGen, we can automatically generate a vulnerability signature even when the format of the attack instance is unknown. We have integrated Tupni with ShieldGen and demonstrated that we can automatically generate the vulnerability signature for a real-world WMF vulnerability given a single malicious WMF file. About the speaker: Weidong Cui is a researcher in the Distributed Systems and Security group at Microsoft Research, Redmond. His research interests lie in the areas of systems and networking security. He received his Ph.D. in Electrical Engineering and Computer Sciences (2006) and his M.S. in Computer Science (2003) from the University of California, Berkeley, and his M.E. (2000) and B.E.

Kenji Takahashi, Trends in Identity Management Oct 29, 2008

Currently many initiatives are being proposed for identity management, such as OpenID, SAML, CardSpace/Information Cards, and OAuth, as its importance is becoming apparent. Identity management is as an integral part of service infrastructures to make identity available to services across organizations in a secure and privacy protected manner. The identity data are crucial to successfully providing the privileged and personalized experiences for legitimate users of services. Also it is important that the users should have strong control over their identity data to foster a socially responsible service industry. This talk will give an overview of trends in identity management, and illustrate best practices and lessons learned in real settings using case studies.

Federica Paci, Access Control and Resiliency for WS-BPEL Oct 22, 2008

Business processes –the next generation workflows- have attracted considerable research interest in the last fifteen years. More recently, several XML-based languages have been proposed for specifying and orchestrating business processes, resulting in the WS-BPEL language. Even if WS-BPEL has been developed to specify automated business processes that orchestrate activities of multiple Web services, there are many applications and situations requiring that people be considered as additional participants that can influence the execution of a process. Significant omissions from WS-BPEL are the specification of activities that require interactions with humans to be completed, called human activities, and the specification of authorization information associating users with human activities in a WS-BPEL business process and authorization constraints, such as separation of duty, on the execution of human activities. This talk investigates the problem of access control and resiliency for WS-BPEL processes. Access control in the context of business process means checking whether a user claiming the execution of an activity is authorized and the execution does not violate authorization constraints. Resiliency means that even if some users become unavailable, the remaining users can still complete the execution of the process according to the stated authorizations and authorization constraints. We present RBAC-WS-BPEL, an RBAC model for WS-BPEL business processes that supports the specification of resiliency constraints, authorizations and authorization constraints on business process activities. Resiliency constraints are evaluated when a WS-BPEL process is deployed, to check if there is a sufficient number of authorized users to perform the process so that authorization constraints are satisfied and the process terminates even if some users become unavailable. Authorizations and authorization constraints are evaluated whenever a user claims the execution of a business process's activity to determine if the execution of the activity by the user does not violate any authorization constraints and does not prevent some other subsequent activities from completing. About the speaker: From Febraury 2008, Dr. Federica Paci is a post-doctoral research associate at Purdue University.Paci's main research interests include access control for web services and business process, digital identity management and trust negotiations.

Adam Dugger, Signature Analysis Coupled With Slicing Analysis for the Validation of Software Oct 15, 2008

What if you could determine exactly where, in any compiled binary, a security threat existed?Answering this question has been the fundamental goal of anti-virus software for many years past, with limited success. Instead, what if you could determine not where security threats do exist, but where they could possibly exist? This is certainly a step in the right direction for total software security -- one which puts us well on our way to being able to develop applications safe against hidden malicious code. All of this is possible with the machine code analysis methodology known as Signature Analysis.However, consider the following question: What if you could determine exactly where, in any compiled binary, a security threat might exist, and, further, precisely what this threat might affect later in the application's execution?This information can be retrieved by combining the capabilities of Code Slicing Analysis with the previously mentioned Signature Analysis. This paradigm not only assists in hardening against currently known threats, but it also identifies areas that are affected by those threats.These principles form the framework for a novel static technique for ensuring software integrity. The goal of this seminar is to present these ideas and to discuss possible future applications. About the speaker: Adam Dugger graduated from Purdue University with a double major in Computer Science and Mathematics in May of 2007. Adam now works for Arxan Defense Systems on a variety of research projects. His presentation focuses on the use of Signature Analysis coupled with Slicing Analysis for detection of malicious code. He has applied known techniques used in anti-virus scanners for use in system integrity checking.

Yuecel Karabulut, Measuring the Attack Surfaces of Enterprise Software Systems Oct 08, 2008

Software vendors have traditionally focused on improving code quality forimproving software security and quality. The code quality improvement effort aims toward reducing the number of design and coding errors in software. In principle, we can use formal correctness proof techniques to identify and remove all errors in software with respect to a given specification and hence remove all its vulnerabilities. In practice, however, building large and complex software devoid of errors, and hence security vulnerabilities, remains a very difficult task. Software vendors can minimize the risk associated with the exploitation of future vulnerabilities. One way to minimize the risk is by reducing the attack surfaces of their software. A smaller attack surface makes the exploitation of the vulnerabilities harder and lowers the damage of exploitation, and hence mitigates the security risk. We believe that a complete risk mitigation strategy requires a combination of code quality efforts and attack surface measurement. SAP and CMU collaborated to develop a new attack surface measurement method for measuring the attack surfaces of SAP software systems implemented in Java. We implemented a tool and demonstrated the feasibility of our approach by measuring the attack surface of an SAP software system. In this talk, we will present the attack surface measurement method and report on its application. About the speaker: Dr. Yuecel Karabulut is a Senior Research Scientist at SAP Research in Palo Alto. He is currently member of the Platforms Research Group.

Dave Keppler, Resilient Systems for Mission Assurance Oct 01, 2008

The ability for information services to continue operating despite attacks is a core enabler of mission assurance goals. Existing security techniques lack this concept of resilience and are inadequate for protecting critical services and data against targeted attacks by sophisticated adversaries. Widely implemented signature and anomaly-based detection techniques fail to keep pace with the advancement of attacker sophistication.Our objective is to develop and prototype resilience techniques that make applications impervious to the damaging effects of attacks without relying on identifying and filtering specific attacks. We employ effects-based countermeasures to impart resilience to applications, creating an environment inhospitable to attack goals, and countering previously unknown attacks on service utility, in particular, code injection and data subversion. About the speaker: David Keppler is a Senior Information Security Scientist in the Information Assurance division at The MITRE Corporation. At MITRE, David has participated in several research projects in information security, including projects on assured information sharing, active worm defense, and attribute-based access control.

Ashish Kamra, Responding to Anomalous Database Requests Sep 24, 2008

Organizations have recently shown increased interest in database activity monitoring and anomaly detection techniques to safeguard their internal databases. Once an anomaly is detected, a response from the database is needed to contain the effects of the anomaly. However, the problem of issuing an appropriate response to a detected database anomaly has received little attention so far. In this work, we propose a framework and a policy language for issuing a response to a database anomaly based on the characteristics of the anomaly. We also propose a novel approach to dynamically change the state of the access control system in order to contain the damage that may be caused by the anomalous request. We have implemented our mechanisms in the PostgreSQL DBMS and we discuss relevant implementation issues. We have also carried out an experimental evaluation to assess the performance overhead introduced by our response mechanism. The experimental results show that the techniques are very efficient. About the speaker: Ashish Kamra is a Phd candidate in School of Electrical and Computer Engineering at Purdue University. He is also enrolled in the interdisciplinary Masters in Information Security degree offered by CERIAS. Ashish received his bachelor's degree in Electronics engineering from Visvesraya Regional College of Engineering, Nagpur (India) in 2001.

Shimon Modi, Fingerprint Sensor Interoperability: Analysis of Error Rates for Fingerprint Datasets Acquired from Multiple Fingerprint Sensors Sep 17, 2008

The last decade has witnessed a huge increase in deployment of biometric systems, and while most of these systems have been single vendor, monolithic architectures the issue of interoperability is bound to arise as distributed architectures are considered for large scale deployments. The distortions and variations introduced when acquiring fingerprint images propagate from the acquisition subsystem all the way to the matching subsystem. These variations ultimately affect performance rates of the overall fingerprint recognition system. Fingerprint images captured using the same sensor technology during enrollment and recognition phases will introduce similar distortions, thus making it easier to compensate for such distortions and reducing its effect on the performance of the overall fingerprint recognition system. However, an impact on performance is expected, but unpredictable, when different fingerprint sensor technologies are used during enrollment and recognition phases. The purpose of this study was to examine the effect of sensor dependent variations and distortions, characteristics of the sensor and characteristics of the finger skin on the interoperability matching error rates of minutiae based fingerprint recognition systems. Fingerprint images were be collected from 9 different fingerprint sensors from 190 subjects for analysis of this research study. A statistical analysis framework for testing interoperability was formulated for this research, which included parametric and non-parametric tests. The statistical analysis framework tested similarity of minutiae count, similarity of image quality and similarity of performance between native and interoperable datasets. Interoperability performance analysis was conducted on each sensor dataset and also by grouping datasets based on the acquisition technology and interaction type of the acquisition sensor. The end objective of this study was to provide greater insight into the effect of a fingerprint dataset acquired from various sensors on performance measured in terms of error rates like false non match rates (FNMR) and false match rates (FMR).

Gabriel Ghinita, Private Queries in Location Based Services: Anonymizers are not Necessary Sep 03, 2008

Mobile devices equipped with positioning capabilities (e.g., GPS) can ask location-dependent queries to Location Based Services (LBS). To protect privacy, the user location must not be disclosed. Existing solutions utilize a trusted anonymizer between the users and the LBS. This approach has several drawbacks: (i) All users must trust the third party anonymizer, which is a single point of attack. (ii) A large number of cooperating, trustworthy users is needed. (iii) Privacy is guaranteed only for a single snapshot of user locations; users are not protected against correlation attacks (e.g., history of user movement).We propose a novel framework to support private location-dependent queries, based on the theoretical work on Private Information Retrieval (PIR). Our framework does not require a trusted third party, since privacy is achieved via cryptographic techniques. Compared to existing work, our approach achieves stronger privacy for snapshots of user locations; moreover, it is the first to provide provable privacy guarantees against correlation attacks. We use our framework to implement approximate and exact algorithms for nearest-neighbor search. We optimize query execution by employing data mining techniques, which identify redundant computations. Contrary to common belief, the experimental results suggest that PIR approaches incur reasonable overhead and are applicable in practice. About the speaker: Gabriel Ghinita is currently a Post-doctoral Research Associate with the Dept. of Computer Science, Purdue University. He holds a a PhD degree in Computer Science from the National University of Singapore.

Minaxi Gupta, Exploitable Redirects on the Web: Identification, Prevalence, and Defense Aug 27, 2008

Web sites on the Internet often use redirection. Unfortunately, without additional security, many of the redirection links can be manipulated and abused to mask phishing attacks. In this work, we prescribe a set of heuristics to identify redirects that can be exploited. Using these heuristics, we examine the prevalence of exploitable redirects present in today's Web. Finally, we propose techniques for Web servers to secure their redirects and for clients to protect themselves from being misled by manipulated redirects.This work was presented at the USENIX Workshop On Offensive Technologies (WOOT) in July, 2008. Subsequently, several online press venues have covered it, including The Washington Post, SC Magazine, and Herald Times.

Hao Chen, Exploiting Opportunistic Scheduling in Cellular Data Networks Apr 02, 2008

Third Generation (3G) cellular networks utilize time-varying andlocation-dependent channel conditions to provide broadband services. They employ opportunistic scheduling to efficiently utilize spectrum under fairness or QoS constraints. Opportunistic scheduling algorithms rely on collaboration among all mobile users to achieve their design objectives. However, we demonstrate that rogue cellular devices can exploit vulnerabilities in opportunistic scheduling algorithms, such as Proprotional Fair (PF), to usurp the majority of time slots in 3G networks. Our simulations show that only five rogue device per 50-user cell can use up to 90% of the time slots, and can cause 2 seconds of end-to-end inter-packet transmission delay on VoIP applications for every user in the same cell, rendering VoIP applications useless. To defend against these attacks, we explore several detection and prevention schemes, including modifications to the PF scheduler and a secure handoff procedure.This is a joint with with Denys Ma, Radmilo Racic, and Xin Liu. About the speaker: Hao Chen is an assistant professor at the Department of Computer Science at the University of California, Davis.

Sencun Zhu, Towards Event Source Location Privacy in Wireless Sensor Networks Mar 26, 2008

For sensor networks deployed to monitor and report real events, event source location privacy is an attractive and critical security property, which unfortunately is also very difficult and expensive to achieve. This is not only because adversaries may attack against sensor source privacy through traffic analysis, but also because sensor networks are very limited in resources. In this talk, we will discuss the techniques we have developed for enhancing source location privacy in sensor networks under a global adversarial model. Specifically, we will propose the notion of statistically strong source anonymity, where carefully chosen dummy traffic will be introduced to hide the real event sources. In addition, several privacy-preserving mechanisms will be employed to drop dummy messages on their roads to the base station to prevent explosion of network traffic. About the speaker: Sencun Zhu is an Assistant Professor at Department of Computer Science and Engineering and College of Information Sciences and Technology, Pennsylvania State University. He received the PhD degree in Information Technology from George Mason University in 2004.

Ta-Wei "David" Wang, Reading the Disclosures with New Eyes: Bridging the Gap between Information Security Disclosures and Incidents Feb 20, 2008

This paper investigates the relationship between information security related disclosures in financial reports and the impacts of information security incidents through cross-sectional and cluster analysis. First, by drawing upon the theories of disclosures in the accounting literature, we examine the effect of the number of disclosures on stock price reactions to information security incidents from 1997 to 2006. Our findings suggest that first-time disclosed information security risk factors in financial reports can mitigate the impact of information security incidents on business value. Second, a cluster analysis is performed on the disclosures in financial reports before and after the incidents. The results demonstrate that companies react to information security incidents by disclosing additional and more specific risk factors in subsequent financial reports. A prediction model is also built to classify disclosures as a belonging to a firm reported in the as breached or non-breached. The model can correctly classify a disclosure with approximately 75% accuracy which help investors and auditors assess information provided by the firm. This paper not only contributes to the literature in information security and accounting but also sheds light on how managers can evaluate their information security policies and convey information security practices more effectively to the investors. About the speaker: Ta-Wei "David" Wang is currently a Ph.D. student in Management Information Systems at Krannert Graduate School of Management, Purdue University. He received his B.B.A and M.B.A from National Taiwan University in Taiwan. He is also a Certified Public Accountant in Taiwan and Certified Internal Auditor.

Myron Cramer, Beyond the Enclave: Evolving Concepts in Security Architectures Feb 13, 2008

This presentation discusses evolving concepts in security architectures. Current security architectures are based on the enclave architecture model. This model organizes and separates networked information systems into trusted, untrusted, and shared areas. Security components are located within these areas to provide the required security services based upon system requirements. While this model has many advantages in a basic client server business model, it has limitations with the evolving need to share information. This talk discusses the enclave security architecture and how it is implemented within enterprise networks. It also discusses information sharing needs that are difficult to meet within the constructs of the enclave as well as some of the security limitations of the enclave model. Potential solutions include incorporating new architectural concepts and new technologies to provide a greater variety of robust enterprise implementation options. About the speaker: Dr. Myron L.

Anand Singh, What are CSO's thinking about? Top information security initiatives for 2008 and beyond … Jan 30, 2008

2006 and 2007 were seminal years which saw emergence of several information security threats and significant data breaches. The media focus on various incidents have made consumers much more aware of information security and hence, any significant security breach results in a significant loss of brand image.As a result, corporate boards are demanding more information security controls as a part of their risk management oversight. This has forced a rethink among the C-suite executives and has increased the importance of information security in their eyes. The CSO's are seeing an elevation in prestige and importance and are becoming empowered to contribute to the organizational strategy by defining information security as a part of organizational governance and risk management framework.The objectives of this talk are two fold. First, the focus will be on practical aspects of information security in most organizations. I will describe how Information Security is becoming a more central function and how the organizational roles and responsibilities are transforming as a result. Second, I will talk about the top information security initiatives for 2008 and what is driving those including examples and explanations of what transpired in several security breaches.

Ventkat Venkatakrishnan, CANDID: Preventing SQL Injection Attacks using Dynamic Candidate Evaluations Nov 28, 2007

SQL injection attacks are one of the topmost threats for applicationswritten for the Web. These attacks are launched through specially crafted user input on web applications that use low level string operations to construct SQL queries. In this talk, I will present a novel and powerful scheme for automatically transforming web applications to render them safe against all SQL injection attacks.A characteristic diagnostic feature of SQL injection attacks is that they change the intended structure of queries issued. Our technique for detecting SQL injection is to dynamically mine the programmer-intended query structure on any input, and detect attacks by comparing it against the structure of the actual query issued. We propose a simple and novel mechanism for mining programmer intended queries by dynamically evaluating runs over benign candidate inputs. This mechanism is theoretically well founded and is based on inferring intended queries by considering the symbolic query computed on a program run. Our approach has been implemented in a tool called CANDID that retrofits Web applications written in Java to defend them against SQL injection attacks. We report experimental results that show that our approach performs remarkably well in practice.(Joint work with Sruthi Bandhakavi, Prithvi Bisht and P. Madhusudan) About the speaker: Dr. V. N.

Steve Myers, Indiana University, Wireless Router Insecurity: The Next Crimeware Epidemic Nov 14, 2007

The widespread adoption of home routers by the general public has added a new target for malware and crimeware authors. A router's ability to manipulate essentially all network traffic coming in to and out of a home, means that malware installed on these devices has the ability to launch powerful Man-In-The-Middle (MITM) attacks, a form of attack that has previously been largely ignored. Making matters worse, many homes have deployed wireless routers which are insecure if the attacker has geographic proximity to the router and can connect to it over its wireless channel. However, some have downplayed this risk by suggesting that attackers will be unwilling to spend the time and resources necessary, nor risk exposure to attack a large number of routers in this fashion. In this talk, we will consider the ability of malware to propagate from wireless router to wireless router over the wireless channel, infecting large urban areas where such routers are deployed relatively densely. We develop an SIR epidemiological model, and use it to simulate the spread of malware over major metropolitan centers in the US. Using hobbyist collected wardriving data from Wigle.net and our model, we show the potential for the infection of tens of thousands of routers in short periods of time is quite feasible. We consider simple prescriptive suggestions to minimize the likelihood that such attacks are ever performed. Next, we show a simple yet worrisome attacks that can easily and silently be performed from infected routers. We call this attack 'Trawler Phishing'. The attack generalizes a well understood failure of many web-sites to properly implement SSL, and allows attackers to harvest credentials from victims over a period of time, without the need to use spamming techniques or mimicked, but illegitimate web-sites, as in traditional phishing attacks, bypassing the most effective phishing prevention technologies. Further, it allows attackers to easily form data-portfolios on many victims, making collected data substantially more valuable. We consider prescriptive suggestions and countermeasure for this attack.The work on epidemiological modeling is joint work with Hao Hu, Vittoria Colizza and Alex Vespignani. The work on trawler phishing is joint work Sid Stamm.

Richard Thieme, Security, Soft Boundaries, and oh-so-subtle Strategies:How to Play Chess While the Board is Disappearing Nov 07, 2007

Non-state and state intelligence are converging in a context of fluid boundaries. It is increasingly difficult to know who is inside and who is not. Creating a trusted network does not resolve the most critical security problems because those problems begin at the interface of the network and the human user. The identity and intention of that human user is critical, but that is often what is most difficult to discern.This emergent world of ambiguous boundaries and multiple identities challenges our models and descriptions of the playing field. Even with a program, we can't always tell the players, because both players and program are morphing.And it's worse than that: the ethical guidelines of the past, rooted in religious systems thousand of years old, are going through the looking-glass, too, along with the structures of spirituality and religion. Identity-shift applies to God and Self as well as the social and cultural structures in which they are embedded.This speech confronts the transformation of the structures in which we live, identifies some consequences of identity-shift, and distinguishes the business of security from the myths of the security business. It points to new ways to organize our lives that complement rather than replace traditional methods of defending electronic and human networks. About the speaker: "And those who were seen dancing were thought to be insane by those who could not hear the music." - Frederick Nietzsche*Richard Thieme has been hearing the music for a long time. His track record includes hundreds of published articles, dozens of published short stories, one published book with more coming, several thousand speeches, and – in a former incarnation - hundreds of sermons, all original, all unique.In the nineteen eighties, Thieme began writing about the impact of new technologies on religious systems and images, on spirituality, on identity. He was an Episcopal priest, and it made sense to begin where he was. What he wrote sounds obvious now. But it didn't, then.He realized that his insights applied to other aspects of society and culture too. What was happening to religions was happening to everything else, a sea change of global transformation driven by new technologies of information and communication. He left the professional ministry to write and speak full time in 1993.Security and intelligence professionals often value his insights because he sees into the heart of complex issues. He takes nothing at face value and links insights to the mixed motives of the human heart, trying to amplify the unheard music playing at the edges of our lives.Mostly he delivers keynotes and closing speeches that unite the diverse themes of a conference. He has spoken in lots of venues - Sydney and Brisbane, Dublin and Amsterdam and Oslo, Israel (for Microsoft), and all around the States, including many hacker cons. Def Con is his favorite, where he spoke in 2007 for the twelfth straight year.

Abhilasha Bhargav-Spantzel, Protocols and Systems for Privacy Preserving Protection of Digital Identity Oct 31, 2007

In order to support emerging online activities within the digital information infrastructure, such as commerce, healthcare, entertainment and scientific collaboration, it is increasingly important to verify and protect the digital identity of the individuals involved. Identity management systems manage the digital identity life cycle of individuals that includes issuance, usage and revocation of digital identifiers.Identity management systems have improved the management of identity information and user convenience; however they do not provide specific solutions to address protection of identity from threats such as identity theft and privacy violation. One major shortcoming of current approaches is the lack of strong verification techniques for management and protection of digital identifiers. Moreover current identity management systems do not consider neither biometric nor history-based identifiers. Both biometric and history-based identifiers are increasingly becoming an integral part of an individual's identity. Such types of identity data also need to be used with other digital identifiers and protected against misuse.In this presentation I introduce a number of techniques that address the above problems. The approach is based on the concept of privacy preserving multi-factor identity verification. The main technique consists of verifying multiple identifier claims of an individual, without revealing extraneous identity information. A distinguishing feature of our approach is that we employ identity protection and verification techniques at all stages of the identity life cycle. In addition we develop techniques to use biometrics in a secure and privacy preserving manner. We also enhance our approach with the use of history-based identifiers. About the speaker: Abhilasha Bhargav-Spantzel is Computer Science PhD Student in Purdue University. She received her bachelors in Computer Science and Mathematics from Purdue in 2002. Her primary research interest is in protocols and systems for protection of digital identity in identity management systems. Her research goal is to provide techniques that perform multi-factor verification of digital identity without jeopardizing privacy. In her work she considers various forms of identity which are attributive, biometric and history based. She actively collaborates with industrial and academic initiatives for identity management tools and standards. Please refer to http://homes.cerias.purdue.edu/~bhargav for more information.

Jill Frisby, Protecting Data Privacy: A Practical Guide to Managing Risk Sep 19, 2007

Protecting valuable information assets, including personal data about employees, students, customers, and medical patients, is an enterprise-wide responsibility. Like all components of good corporate governance, it begins with senior leadership establishing a culture of awareness about the importance of safeguarding these assets, and extends through coordinated actions among all business units, divisions, and departments. When creating data privacy programs, organizations should align them with their strategic enterprise risk management objectives and follow a top-down approach to achieve the greatest benefit.This presentation will focus on a practical approach to data privacy, that seeks to understand the business needs for data and align a data privacy protection program to those needs. Effective programs prevent companies from ending up in the news, disclosing a data loss, by enabling its employees to stay vigilant for situations where data may be at risk. Topics to be discussed include:* The Goals of an Effective Data Privacy Program* Current Data Privacy Landscape* Common Privacy Program Pitfalls* Key Components of a Successful Data Privacy Program* The Top Down Data Privacy Risk Assessment* Data Privacy Roles and Responsibilities* High Level Roadmap and Ideas to Consider for Future Strategy About the speaker: Jill Frisby is a Manager in the Risk Consulting Practice with a specialty in the area of Information Security and Data Privacy.

Ron Buskey, Security issues within embedded software development Sep 12, 2007

Software development processes and tools used for small communication devices have changed significantly over the years. Some of these practices and processes have resulted in improvements in quality and time to market for their target products, but in some cases have unintended results for the security and trustedness of those same products. This talk will look at several of these practices and approaches that can drive improvements in quality and productivity metrics for embedded communication software development teams yet create vulnerabilities and/or weaken the security architecture for those products. About the speaker: Ron Buskey leads a team in Motorola Labs focused on security architecture for future product platforms. This research includes techniques for trusted operation and information protection at a fundamental level so that product applications do not have to be concerned with all of the security issues. Ron is working with component providers to design and build security into the platform elements to be used in Motorola product platforms. This will produce enhanced trusted platforms that will be resistant to virus and software hacking attacks on the Motorola products. Previous to working in Motorola Labs, Mr. Buskey spent time as the security architect for the Motorola Mobile Devices Business. He also worked as the lead software engineer for Motorola's Secure Products business. Since graduating from Rochester Institute of Technology in Rochester N.Y. in 1981 with a BSEE, Ron has held software architecture, secure communications design and computer engineering assignments.

Yvo Desmedt, Applying Recreational Mathematics to Secure Multiparty Computation Sep 05, 2007

The problem of a mice traveling through a maze is well known. The maze can be represented using a planar graph. We present a variant of the maze. We consider a grid vertex colored planar graph in which an adversary can choose up to t colors and remove all vertices that have these colors and their adjacent edges. We call the grid in which these vertices and adjacent edges are removed a reduced grid. The problem is that a mice must be able to move in the reduced grid from the first row to the last row, and from the first column to the last column, and this for all possible reductions. We present three types of solutions to construct such grids. The efficiency of these solutions is discussed.The problem finds its origin in the problem of secure multipartycomputation. Imagine going to a medical doctor in Iraq who needs to prescribe some medication, which might be counterindicated. The typical solution is to disclose all medical records to the doctor. If secure multiparty computation would be used, the medical doctor in Iraq only learns from the distributedmedical databases whether the medication is, or is not, counterindicated. We consider the problem of parties each having a secret belonging to a non-abelian group. The parties want to compute the product of these secrets without leaking anything that does not follow trivially from the product. Oursolution is black box, i.e., independent of the non-abelian group. This has applications to threshold block ciphers and post-quantum cryptography. About the speaker: Yvo Desmedt received his Ph.D. (Summa cum Laude) from the University of Leuven, Belgium (1984).

Klemens Boehm, Towards Effective and Efficient Behavior-based Trust Models Aug 29, 2007

Trust models have been touted to facilitate cooperation among unknown entities. In our current work, we are interested in behavior-based trust models, i.e., models that derive the trustworthiness of an entity from its behavior in previous interactions. Existing proposals in this field typically feature one specific trust model. Further, various publications exist which have proposed different centrality measures to rank individuals, i.e., compute their reputation based on feedback, and have demonstrated their effectiveness in certain (rather specific) situations. This presentation in turn proposes a framework for behavior-based trust models for open environments with the following distinctive characteristic. Based on a relational representation of behavior-specific knowledge, we propose a trust-policy algebra allowing for the specification of a wide range of trust policies. Since the evaluation of the standing of an entity requires centrality indices, we propose a first-class operator of our algebra for their computation. The presentation concludes with an objective comparison of the effectiveness of the various centrality measures in reputation systems. About the speaker: Klemens Böhm is full professor for computer science at Universität Karlsruhe (TH). Before joining Karlsruhe University in 2004, he has been a professor at Magdeburg University. Prior to that, he has been affiliated with ETH Zurich and GMD Darmstadt. His research interests are distributed information systems, e.g., Peer-to-Peer systems and Grid infrastructures, data management in ubiquitous environments, and data warehousing. Klemens puts much effort in interdisciplinary research and application-oriented projects, currently ranging from biosys-tematics to traffic-data management.

Bill Horne, Role Discovery Aug 22, 2007

The first step in migrating to a role based access control (RBAC) system, is role development, in which teams of people meticulously define sets of roles that meet the needs of an organization's security and business requirements. Because it is so labor intensive, role development is the most expensive step in migrating to RBAC. In this talk, I will describe an approach called role discovery to help assist with the role development process. We attack the problem by finding simplifications of a bipartite graph that models the existing access control rules. Biclique covers of this graph are a fundamental tool in our approach. I will describe some of the theoretical background of this problem as well as some experimental results testing the approach on several real-world datasets.

Umut Topkara, Passwords Decay, Words Endure: Towards Secure and Re-usable Multiple Password Mnemonics Apr 25, 2007

Human aspects of information security were identified at the early stages in the history of time shared computing. The recent surge in attacks that exploit security vulnerabilities involving human factors have also put them under the spotlight of various research fields including human-computer interaction, information security and cognitive science. The human centered vulnerabilities involve an interplay of a broad range of actors from Information Technology specialists (who might mis-configure the security hardware and software or enforce impractical security policies) to end users (who might have a poor understanding of good security practices or not know the possible impact of weak security).This talk will focus on human aspects of authentication mechanisms. I will present two methods that we have developed to reinforce the security of existing systems by improving their usability.Previous studies have repeatedly shown that users find it taxing to remember truly random passwords. Many users choose easy to guess --therefore not secure-- passwords, since they require the least effort to recall. Experienced users adopt "mnemonic phrases" to generate and easily recall more secure passwords. However, regularity in the human languages may render such passwords vulnerable against a brute force attack. In the first part of the talk, I will present a method that we developed to automatically generate mnemonic phrases which can yield secure passwords in an effort to increase the usability of text password authentication.Many computer users need to remember a multiplicity of usernames and passwords for different systems, and the users tend to reuse passwords across these systems which may have different security guarantees. In such cases remembering a different mnemonic phrase for each password does not scale and quickly becomes a challenging task. In the second part of the talk, I will present a scheme that helps the users remember a multiplicity of truly random passwords. The new scheme is applicable to an existing password authentication system without any modification, as it does not require any form of involvement from the service provider (e.g., bank, brokerage). Nor does it require the user to have any computing device at hand (not even a calculator). The scheme is such that changes to passwords do not necessitate a change in what the user remembers. Hence, passwords can be frequently changed without any additional burden on the memory of the user, thereby increasing the system's security. About the speaker: Umut Topkara is a PhD candidate at the Computer Science Department of Purdue University. His research interests lie at the confluence of Information Security, Natural Language Processing and Computer- Human Interaction, specifically their intersection in the field of Usable Security. More recently, he has also been involved in Grid Middle-ware Engineering research. His thesis advisor is Professor Mikhail J. Atallah. He got his B.Sc. and M.Sc. degrees from Computer Engineering Department of Bilkent University. He started his graduate studies at Purdue University in 2002.

Mercan Topkara, Hiding the Message Behind the Words: Advances in Natural Language Watermarking Apr 18, 2007

The Internet has become one of the main sources of knowledgeacquisition, harboring resources such as online newspapers, webportals for scientific documents, personal blogs, encyclopedias, andadvertisements. It has become a part of our daily life to search andaccess this immense amount of online information, and more recently wehave also started to contribute to this pool of information our owncreativity in the form of text, images and video. Unfortunately, it isstill an open question as to how we, as authors, can control the waythat the information we create is distributed or re-used.Rights management problems are serious for text since it is much easyfor other people to download and manipulate copyrighted text fromInternet and later re-use it free from control. There is a need for arights protection system that ``travels with the content''. Digitalwatermarking is an information hiding mechanism that embeds thecopyright information in the document. Besides traveling with thecontent of the documents, digital watermarks are also imperceptible(i.e., seamless) to the user, which makes the process of removing themfrom the document challenging.Using linguistic features for information hiding into natural language text is an exciting and new idea. This talk begins with a short surveyof existing technologies in natural language watermarking, and thenfocuses on a recently developed natural language watermarking systemthat is practical, easy-to-use and provides resilience to attacks throughthe use of ambiguity in natural language. The talk is aimed for a generalaudience, and will be self-contained covering the necessary backgroundinformation. About the speaker: Mercan Topkara is a PhD candidate at the Computer Science Departmentof Purdue University working with Mikhail J. Atallah and CristinaNita-Rotaru.

Dr. Charles P. Pfleeger, Dumb Ideas in Computer Security Apr 11, 2007

Every profession goes through mistakes and unwise steps, especially in its early years. It is through trial and error that leaders and innovators of the profession are able to advance knowledge. Computer security is no exception. Both insiders' and outsiders' choices have held back and even harmed the state of computing. Of course, hindsight is usually more accurate than foresight.This talk picks a handful of ideas that in retrospect have turned out dumb, ideas such as compound complexity, single-state hardware, downloaded code, and incomplete mediation. For each idea we will see from where the idea came, why it is unwise, and why we should have known better. From these examples, we will see how better choices can be made in the future. About the speaker: Dr Charles P Pfleeger is a consultant, speaker, educator and author on computer and information system security. He has over thirty years experience in computing. A former professor of computer science at the University of Tennessee, he has done consulting and research work in the U.S. and abroad. He is now an independent consultant with the Pfleeger Consulting Group. His book, Security in Computing 4th edition, co-authored with Shari Lawrence Pfleeger, was just published by Prentice-Hall.

Dr. Albert M. K. Cheng, Automatic Debugging and Verification of RTL-Specified Real-Time Systems via Incremental Satisfiability Counting and On-Time and Scalable Intrusion Detection in Embedded Systems Mar 28, 2007

Abstract 1:Real-time logic (RTL) is useful for the verification of a safety assertion with respect to the specification of a real-time system. Since the satisfiability problem for RTL is undecidable, the systematic debugging of a real-time system appears impossible. With RTL, each propositional formula corresponds to a verification condition. The number of truth assignments of a propositional formula can help us determine the specific constraints which should be added or modified to derive the expected solutions. This talk describes this debugging approach and how it can be embedded into autonomous systems. We have implemented a tool called ADRTL for automatic debugging of RTL specifications. The confidence of our approach is high as we have effectively evaluated ADRTL on several existing industrial applications, including the NASA X-38 Crew Return Vehicle avionics.Abstract 2:Embedded systems are becoming ubiquitous and are increasingly interconnected or networked, making them more vulnerable to security attacks. A large class of these systems such as SCADA and PCS has real-time and safety constraints. Therefore, in addition to satisfying these requirements, achieving system security emerges as a critical challenge to ensure that users can trust these embedded systems to perform correct operations. One objective in a secure system is to identify attacks by detecting anomalous system behaviors. This part of the talk describes the challenges in the design and implementation of such intrusion detection system (IDS), addressing (1) accuracy: the IDS identifies no or as few false positives as the resource (time, space, power, etc.) and/or policy constraints allow, and no or as few false negatives as the resource and/or policy constraints allow; (2) efficiency/timeliness: the IDS does not violate the host embedded system's application deadlines and has a reasonable space overhead; (3) scalability: the IDS can scale to work with large embedded systems; and (4) power-awareness: the IDS does not significantly reduce the operational period of battery-powered embedded systems. We conclude with an outline of one of several promising embedded IDS approaches under investigation. This approach is based on automatic rule-base generation and semantic analysis.

Dan Geer, A quant looks at the future Mar 21, 2007

If there is a difference between information and bits we had better find it soon. The bit-count is bounding upward, no one dares throw anything away, and once "search" supplants "organize" there is no going back. Information may or may not want to be free, but it wants to be in motion, so much so that ISPs see their future in movie rentals and the speed of light determines how far away your trade submission servers can be from the Exchange and still do micro-arbitrage. Like a gas, information has to be collected, purified, and compressed to be of value, so any leak, impurity, or loss of containment is a loss of value, per se. The street price of drugs has a more stable floor than the street price of stolen data, the percentage of attack tools that are privately held is rising, and the workfactor for information defense is the integral of the workfactor for information offense, yet we do not have the quantitative tools to value our information. That is possibly the key -- quantitative information risk management that is on par with quantitative financial risk management.

Eugene Schultz, Intrusion Detection Event Correlation: Approaches, Benefits and Pitfalls Mar 07, 2007

Over the years intrusion detection technology has improved to the point that it is highly useful to both the commercial and non-commercial sector. This technology is, however, by no means anything close to perfect. Even the best intrusion detection systems miss a fairly large proportion of attacks that occur; they also tend to yield unacceptably high false alarm rates. Correlating the output of multiple systems and devices is a promising solution for the limitations in today's intrusion detection systems. There have been numerous advances in intrusion detection event correlation, yet this technology lags behind intrusion detection technology. How events are correlated makes a big difference concerning the value of event correlation. This talk will cover the various approaches to event correlation as well as their advantages and disadvantages. About the speaker: Eugene Schultz, Ph.D., CISM, CISSP, is the Chief Technology Officer and Chief Information Security Officer at High Tower Software, a company that develops security event management software. He is the author/ co-author of five books, one on Unix security, another on Internet security, a third on Windows NT/2000 security, a fourth on incident response, and the latest on intrusion detection and prevention.

Bhavani Thuraisingham, Assured Information Sharing between Trustworthy, Semi-trustworthy and Untrustworthy Coalition Partners Feb 28, 2007

Data mining is the process of posing queries and extracting patterns, often previously unknown from large quantities of data using pattern matching or other reasoning techniques. Data mining has many ap-plications in security including for national security as well as for cyber security. The threats to national security include attacking buildings, destroying critical infrastructures such as power grids and telecom-munication systems. Data mining techniques are being investigated to find out who the suspicious people are and who is capable of carrying out terrorist activities. Cyber security is involved with protecting the computer and network systems against corruption due to Trojan horses, worms and viruses. Data mining is also being applied to provide solutions such as intrusion detection and auditing. The first part of the presentation will discuss my joint research with Prof. Latifur Khan and our students at the University of Texas at Dallas on data mining for cyber security applications For example; anomaly detection techniques could be used to detect unusual patterns and behaviors. Link analysis may be used to trace the viruses to the perpetrators. Classification may be used to group various cyber attacks and then use the profiles to detect an attack when it occurs. Prediction may be used to determine potential future attacks depending in a way on information learnt about terrorists through email and phone conversations. Data mining is also being applied for intrusion detection and auditing. Other applications include data mining for malicious code detection such as worm detection and managing firewall policies.This second part of the presentation will discuss the various types of threats to national security and de-scribe data mining techniques for handling such threats. Threats include non real-time threats and real-time threats. We need to understand the types of threats and also gather good data to carry out mining and obtain useful results. The challenge is to reduce false positives and false negatives. The third part of the presentation will discuss some of the research challenges. We need some form of real-time data mining, that is, the results have to be generated in real-time, we also need to build models in real-time for real-time intrusion detection. Data mining is also being applied for credit card fraud de-tection and biometrics related applications. While some progress has been made on topics such as stream data mining, there is still a lot of work to be done here. Another challenge is to mine multimedia data including surveillance video. Finally, we need to maintain the privacy of individuals. Much research has been carried out on privacy preserving data mining. In summary, the presentation will provide an overview of data mining, the various types of threats and then discuss the applications of data mining for malicious code detection and cyber security. Then we will discuss the consequences to privacy.

Stuart Shapiro, Scenario-Driven Construction of Enterprise Information Policy Feb 07, 2007

Information policy at the enterprise level is invariably an exercise in gaps and inconsistencies. The range of concerns—including security—is broad, the environment tends to be heterogeneous and dispersed, the contextual scope is significant, and the stakeholders are numerous. MITRE ran headlong into this problem as it set about conceiving and implementing a new enterprise IT architecture, with questions increasingly raised regarding what policies the new architecture had to be capable of supporting. The MITRE Information Policy Framework (MIPF) is the mechanism MITRE developed to answer these questions. The MIPF supports systematic, structured analysis and formulation of information policy in five areas: security, privacy, management, stewardship, and sharing. This presentation will discuss the structure and use of the MIPF, with an emphasis on security requirements. About the speaker: Dr. Stuart S. Shapiro is a Lead Information Security Scientist and a member of the Privacy Practice at the MITRE Corporation, a not-for-profit company performing contract technical research and consulting primarily for the U.S. government. At MITRE he has supported a wide range of privacy activities, including privacy impact assessments, for major government programs. Prior to joining MITRE he was Director of Privacy at CareInsite, an e-health company, where his responsibilities included both policy and technical issues revolving around privacy and security. He has also held academic positions in the U.S. and the U.K. and taught courses on the history, politics, and ethics of information and communication technologies (ICTs). His research and writing have focused on ICTs and privacy and on the history and sociology of software development. Among his professional affiliations are the Association for Computing Machinery (ACM)—including its public policy committee, USACM—and the International Association of Privacy Professionals (IAPP).

Wojciech Szpankowski, What is Information? Jan 24, 2007

Information permeates every corner of our lives and shapes ouruniverse. Understanding and harnessing information holds the potential forsignificant advances. The breadth and depth of underlying concepts ofthe science of information transcend traditional disciplinary boundariesof scientific and commercial endeavors. Information can be manifestedin various forms: business information is measured in dollars; chemical information is contained in shapes of molecules; biological information stored and processed in our cells prolongs life. So what is information? In this talk we first attempt to identify the most important features of information and define it in the broadest possible sense. We subsequently turn to the notion and theory of information introduced by Claude Shannon in 1948 that served as the backbone for digital communication. We go on to bridge Shannon information with Boltzmann's entropy, Maxwell's demon, Landauer's principle and Bennett's irreversible computations. We point out, however, that while Shannon created a successful and beautiful theoryof information for communication, a wide spread application of informationtheory to economics, biology, life science and complex networks seems to bestill awaiting us. We shall discuss some examples that recently crop up inbiology, chemistry, computer science, and quantum physics. We concludewith a list of challenges for future research.We hope to put forward some educated questions, rather than answers, to the issues and tools that lay before researchers interested in information. About the speaker: Before coming to Purdue, Wojciech Szpankowski was assistant professor at the Technical University of Gdansk, and in 1984 he was assistant professor at the McGill University, Montreal. During 1992-93, he was professeur invité at INRIA, Rocquencourt, France. His research interests cover analysis of algorithms, data compression, information theory, analytic combinatorics, random structures, networking, stability problems in distributed systems, modeling of computer systems and computer communication networks, queueing theory, and operations research. His recent work is devoted to the probabilistic analysis of algorithms on words, analytic information theory, and designing efficient multimedia data compression schemes based on approximate pattern matching. He is a recipient of the Humboldt Fellowship. He has been a guest editor for special issues in IEEE Transactions on Automatic Control, Theoretical Computer Science, Random Structures & Algorithms, and Algorithmica. Currently, he is editing a special issue on "Analysis of Algorithms" in Algorithmica. He serves on the editorial boards of Theoretical Computer Science, Discrete Mathematics and Theoretical Computer Science, and the book series Advances in the Theory of Computation and Computational Mathematics.

Vipin Swarup, Research Challenges in Assured Information Sharing Jan 17, 2007

Assured information sharing has been a "grand challenge" problem ofinformation security for several decades. Currently, there is broadconsensus that the state-of-practice of information sharing isinadequate. One primary problem is that people on the field (e.g.,soldiers, firefighters) have mission-critical need for sensitiveinformation but are often among the least trusted principals in theirorganizations and hence do not receive the information. Anotherproblem is that data producers claim ownership of the data theyproduce and place sharing constraints on that data despite thecompeting interests of multiple parties over that data. In this talk,we highlight these and other problems and discuss a wide range oftechnical solutions that are needed. We elaborate on the need tobalance the risks of sharing data with the risks of not sharing dataand present several proposed approaches for doing so. We alsodescribe how obligation policies play an important role in addressingsome information sharing issues. About the speaker: Vipin Swarup is a Principal Scientist in the Information SecurityDivision at The MITRE Corporation. He received a B.Tech. degree inComputer Science and Engineering from IIT Bombay, and M.S. andPh.D. degrees in Computer Science from the University of Illinois atUrbana-Champaign. His doctoral work was in the area of type theoryand dealt with adding assignments to applicative programminglanguages. In 1991, he developed techniques to formally verifyvirtual machines, and he applied those techniques to an interpreterfor the Pre-Scheme programming language. In 1993, he created ahigh-assurance domain-specific programming language system called Feltfor security guard filters -- Felt has been used to express andenforce cross-domain message filtering policies in commercial securityguard products. In 1996, he co-authored a widely cited paper onmobile agent security. In 2003, he was a co-founder of the ACMWorkshop on Security of Ad Hoc and Sensor Networks.Dr. Swarup has been the principal investigator of numerous researchprojects in information security, including projects on mobile agentsecurity, security guards, intrusion detection, trust management,location-based security, and web services security.

Virginia Rezmierski, Computer-Related Incidents: Factors Related to Cause and Prevention Jan 10, 2007

Computer-related incidents that have the potential to destabilize, violate, or damage, the resources, services, policies, or data of the community or individual members of the community are happening in increasing numbers. Despite the news, we know that they are happening not just in academia which has been painted as insecure and wide-open, but in corporate and not-for-profit environments as well. We have inclinations about what is causing these incidents, but now we also have facts. While we look for technical fixes to the problems, the real factors that are related to the cause of these incidents may not be technical at all, but rather human. This presentation will discuss the "Computer Incident Factor Analysis and Categorization Project", CIFAC, which was carried on at the University of Michigan under funding from the National Science Foundation. Dr. Rezmierski will present the project findings and will discuss what they mean for colleges, universities, corporations, not-for-profit organizations and individuals. The presentation will include discussion of actual incidents, the statistical methodology and findings, and the recommendations put forward by the researcher team. About the speaker: Virginia completed a BA in Sociology and Political Science from the Maxwell School of Citizenship at Syracuse University in the mid 1960's. She then completed an MA in Psychopathology and Special Education from Syracuse University and taught emotionally disturbed boys for two years in the Syracuse Public Schools. She moved from New York to assume a position at the University of Michigan Children's Psychiatric Hospital in Ann Arbor. There she designed a school liaison program, did psychotherapy, and led a treatment team researching and providing therapy and education for autistic in-patient children.In the early 1970's she received her Ph.D. in Educational Psychology from the University of Michigan, with a research specialization in non-verbal communication and aggression. She worked for several years as a consultant for area schools in the management of behaviorally disordered youth. During the next five years she served as Director of Special Education for four school districts in Michigan and spoke widely at the state and national level on topics related to non-verbal communication, behavior management, and emotional disturbance. While at Syracuse University, she began her college level teaching career, providing a graduate course in child development and psychopathology. In the late 1970's she moved from program administration to full time research and teaching, providing courses at the University of Michigan-Dearborn campus in teaching methods, educational psychology, and behavior management. Her research focused on designing developmentally prescriptive interventions for troubled youth. In the early 1980's Virginia changed the direction of her career to learn more about the information technology revolution that was occurring on college and university campuses. For approximately 20 years she was the Director of the Office of Policy Development and Education at the University of Michigan, where she led a team of policy analysts researching and analyzing information technology related policy issues. She has published numerous articles regarding information technology and ethics, privacy, security, and community building. She continues to speak nationally and locally on these issues as well and has led several national research projects to examine the costs and causes associated with information technology related abuse incidents. In June, 2000, Virginia retired from her administrative responsibilities at the University of Michigan. She continues, however, to hold teaching appointments in three of the colleges at the University of Michigan. For the Ford School of Public Policy she provides a graduate course entitled: "Technology, Emerging Law, and Applied Policy". For the School of Information she provides a graduate course entitled: "Ethics and Values". She also holds an appointment at the School of Education. In 2002 she continued her research activities completing a National Science Foundation research project designed to examine the interface between systems logging and monitoring activities and student record privacy protections. Currently, she is publishing and speaking about the results of another National Science Foundation funded research project involving 36 colleges and universities and 28 corporate and not-for-profit organizations. The project investigated the causes of over 400 computer-related incidents and identified the best practices for preventing and managing such incidents.

Dongyan Xu, OS-Level Taint Analysis for Malware Investigation and Defense Nov 29, 2006

The Internet is facing threats from increasingly stealthy andsophisticated malware. Recent reports have suggested that newcomputer worms and malware deliberately avoid fast massivepropagation. Instead, they lurk in infected machines and inflictcontaminations over time, such as rootkit and backdoorinstallation, botnet creation, and data/identity theft. In defenseagainst Internet malware, the following tasks are critical: (1)raising timely alerts to trigger a malware investigation, (2)determining the break-in point of malware, i.e. the vulnerablesoftware via which the malware initially infiltrates the victim,and (3) identifying all contaminations inflicted by the malwareduring its residence in the victim. In this talk, I will presentProcess Coloring, an information flow-preserving, provenance-awareapproach to malware investigation. In particular, I willdemonstrate that through the preservation and tainting of malwarebreak-in provenance along OS-level information flows, malwareinvestigators will be able to improve the efficiency andeffectiveness of existing log-based intrusion investigation tools.Furthermore, process coloring brings the new capability of runtimemalware alert, which cannot be achieved by existing log-basedtools. I will also present results of our experiments with anumber of real-world Internet worms as well as a highlytamper-resistant implementation of process coloring usingvirtualization-based techniques. About the speaker: Dongyan Xu is an assistant professor of computer science at PurdueUniversity. He received his Ph.D. in computer science from theUniversity of Illinois at Urbana-Champaign in 2001. His currentresearch focuses on virtualization technologies and theirapplications to malware defense on the Internet and virtualdistributed computing in the cyberinfrastructure.

David Zage, Mitigating Attacks Against Measurement-Based Adaptation Mechanisms in Unstructured Multicast Overlay Networks Nov 08, 2006

Many multicast overlay networks maintain application-specific performance goals such as bandwidth, latency, jitter and loss rate by dynamically changing the overlay structure using measurement- based adaptation mechanisms. This results in an unstructured overlay where no neighbor selection constraints are imposed. Although such networks provide resilience to benign failures, they are susceptible to attacks conducted by adversaries that compromise overlay nodes. Previous defense solutions proposed to address attacks against overlay networks rely on strong organizational constraints and are not effective for unstructured overlays. In this work, we identify, demonstrate and mitigate insider attacks against measurement-based adaptation mechanisms in unstructured multicast overlay networks. The attacks target the overlay network construction, maintenance, and availability and allow malicious nodes to control significant traffic in the network, facilitating selective forwarding, traffic analysis, and overlay partitioning. We propose techniques to decrease the number of incorrect or unnecessary adaptations by using outlier detection. We demonstrate the attacks and mitigation techniques in the context of a mature, operationally deployed overlay multicast system, ESM, through real- life deployments and emulations conducted on the PlanetLab and DETER testbeds, respectively.

Paula DeWitte, Developing an Operational Framework for Integrated System Security Nov 01, 2006

Systems are composed of multiple complex levels including the physical infrastructure, personnel or "humans-in-the-loop", administration policies and procedures, computers, networks, and the communication protocols for connectivity that tie the system into a workable unit. Each aspect is in itself a complex system. When we consider system security, we tend to focus on the electronic components—the connectivity, computers, and network—over the non-electronic. Although we rigorously implement security in the various system components, the security is rarely integrated across the boundaries of the entire system spectrum. We tend to implement security on the distinct levels of the system without considering the impact or interaction with other system levels. For example, we may fully implement encryption, passwords, and firewalls and feel that our electronic systems are secure, while the weakest link may be staff members who fall victim to social engineering techniques and unknowingly reveal sufficient information to allow a perpetrator to circumvent our best security. Or we may have fortified computer systems and well trained personnel, but neglect the fact that we are being monitored through the building's walls, floors, and windows. Without true understanding of the nature of the interactions of the system, we cannot fully understand how vulnerabilities in one level of the system such as the physical infrastructure can be exploited to allow attacks on another level such as the computer networks. By taking advantage of these vulnerabilities, perpetrators are able to circumvent even the most effective computer and network security, breach that security, and achieve their goals. We only need to consider the current challenges of insider threats or threats from coordinated attacks on the physical infrastructure and the computer networks to appreciate the need for better integrated system security. Our goal is to provide analytical tools for the real world, focusing on the decision makers who implement security policies across the system spectrum. Further, to be effective, these analytical tools must be implemented within an organizing framework that provides both an integrated view of security as well as the insight and understanding necessary to make effective security issues. This necessitates the development of step-by-step processes for analyzing and implementing security decisions. While this may seem to be a soft and less complete technical solution, it is actually implementing technology at the highest level because of the integration required to address each aspect of the system as well as the multi-disciplinary approach blending computer science, engineering, psychology, linguistics, and management in developing such analytic tools. This presentation will discuss work in progress in developing these analytical tools as well as the overarching framework for implementing integrated system security. Our intention is to understand "what can be" or "what could happen". With this insight, they can more effectively provide prevention, protection, or remediation strategies.

As a mid-career redefinition, she is currently pursuing a law degree at St. Mary's Law School in San Antonio, TX where she intends to focus on technology and privacy issues. She also holds a B.S. and M.S. from Purdue University.

Qihua Wang, Beyond Separation of Duty: An Algebra for Specifying High-level Security Policies Oct 25, 2006

A high-level security policy states an overall requirement for a sensitive task. One example of a high-level security policy is a separation of duty policy, which requires a sensitive task to be performed by a team of at least k users. It states a high-level requirement about the task without the need to refer to individual steps in the task. While extremely important and widely used, separation of duty policies state only quantity requirements and do not capture qualification requirements on users involved in the task. This talk will introduce a novel algebra that enables the specification of high-level policies that combine qualification requirements with quantity requirements motivated by separation of duty considerations. A high-level policy associates a task with a term in the algebra and requires that all sets of users that perform the task satisfy the term. The syntax and semantics of the algebra, as well as the algebraic properties of its operators will be presented. The talk will also discuss results for computational problems related to thealgebra and compare the algebra with regular expressions. About the speaker: QihuaWang is a PhD student in Department of Computer Science, Purdue University. He received his Bachelor's degree in computer science from University of Science and Technology of China (USTC), in 2004. His research interest is access control policy management.

Nitin Khanna, Forensics Characterization of Printers and Image Capture devices Oct 18, 2006

The falling cost and wide availability of electronic devices have led to theirwidespread use by individuals, corporations, and governments. These devices,such as computers, cell phones, digital cameras, and printers, all containvarious sensors which generate data that are stored or transmittedto another device. One example of this is a security system containing anetwork of video cameras, temperature sensors, alarms, computers, and otherdevices. In such a network, it is important to be able to trust the data fromeach of these sensors. Forensic techniques can be used to uniquely identifyeach device using the data it produces. This is different from simply securingthe data being sent across the network because we are also authenticating thesensor that is creating the data.Forensic characterization of a device allows identification of the type ofdevice, make, model, configuration, and other characteristics based solely onobservation of the data that the device produces. These characteristicsthat uniquely identify a device are called device signatures. As an example,the noise characteristics in a digital image can be used as a signature of thecamera that produced it. Similarly, the ‘‘noise'' characteristics of a printengine can be used as a signature of the printer that generated a document.This talk will present current research and techniques for forensiccharacterization of printers and image capture devices such as digitalcameras and scanners. About the speaker: Nitin Khanna is a PhD candidate in Electrical and Computer Engineering at PurdueUniversity, after finishing his Bachelor of Technology at IIT Delhi,India, in 2005. He is currently working on image forensics for digital camerasand scanners. His research interests are in image processing and multimediasecurity.

Danfeng Yao, Verification of Integrity for Outsourced Content Publishing and Database Queries Oct 04, 2006

In outsourced content publishing, the data owner gives the content to a service provider who answers requests from users. Similarly, in outsourced databases, the data owner delegates a service provider to answer queries. Outsourcing enables fast and fault-tolerant delivery of information. However, since service providers in outsourced systems may not be trusted by users, the user needs to verify the integrity ofinformation obtained.First, I present a cryptographic solution for the verification of pseudonymized documents. A document can be pseudonymized by the service provider on the fly, based on the data owner's policies and the user's access permissions. Our pseudonym protocol is simple and efficient, and only requires the data owner to prepare and sign the document once.Second, I present a solution for integrity verification of database aggregate queries, such as sum and max. We design proofs of correctness and completeness of aggregate results. What makes the problem challenging is that individual data entries may be sensitive (such as in medical databases), and should not be revealed to the user. We givecryptographic protocols to support verification of query results in a privacy-preserving fashion. About the speaker: Danfeng Yao is a fifth-year graduate student in the Computer Science Department at Brown University, Providence, Rhode Island. She obtained her B.S degree from Peking University, China, and Master degrees from Princeton University and Indiana University at Bloomington. Her thesis research is focused on cryptographic protocols indecentralized trust management, under the advising of Professor Roberto Tamassia.

Ravi Sandhu, The Secure Information Sharing Problem and Solution Approaches Sep 27, 2006

The secure information sharing problem is one of the oldest and most fundamental and elusive problems in information security. Mission objectives dictate that Information must be shared and made available to authorized recipients, and yet information must be protected from leakage and subversion by malicious insiders and malicious software. The doctrine of "share but protect" indicates the inherent conflict in achieving effective secure information sharing. In this talk we demonstrate the complexity and richness of the secure information sharing problem space. We then identify some "sweet spots" that appear promising in their practical benefit and feasibility of solutions. We describe the PEI models approach to decompose security problems into the three layers of policy models (topmost), enforcement models (middle), and implementation models (bottom). We discuss how this approach can be applied to the secure information sharing problem. Finally we indicate how modern trusted computing technology can be used to solve important variations of this problem. About the speaker: Dr. Ravi Sandhu earned B.Tech. and M.Tech. degrees from IIT Bombay and Delhi respectively, and M.S. and Ph.D. degrees from Rutgers University. He is a Fellow of ACM and IEEE, and recipient of the IEEE Computer Society Technical Achievement Award. His research has focused on information security, privacy and trust, with special emphasis on models, protocols and mechanisms. His doctoral work on safety and expressive power of access control was further developed by him culminating in the Typed Access Matrix in 1992. In collaboration with Prof. Jajodia, he analyzed and reconciled confidentiality and integrity in multilevel secure databases. In 1993 he showed that Chinese Wall separation of duty policies were instances of information flow. In 1996, along with industry colleagues, he published the seminal paper on role-based access control which evolved into the 2004 NIST/ANSI standard RBAC model. In 2002, with Jaehong Park, he introduced the Usage Control model for next-generation access. Other recent activities include Information Sharing models and implementations using Trusted Computing, and the PEI (policy, enforcement and implementation) layered models method for synthesizing secure systems.

Gene Kim, Prioritizing Processes and Controls for Effective and Measurable Security Sep 20, 2006

Are your security & IT controls really effective? Do you know how your security & IT operations compare to high performers? In this presentation, Gene Kim will share the work he has been doing over the last six years with the IT Process Institute (ITPI), Software Engineering Institute, and Institute of Internal Auditors, codifying the observed practices of high-performing IT organizations. These high performers have a culture of change management, a culture of causality and a perpetual desire to detect variance before it causes a catastrophic event.Specifically, Gene will discuss the ITPI IT Controls Benchmarking Survey of practice, a recently completed research project which has quantified the value, effectiveness, efficiency and security of controls. This landmark research has uncovered an alternative approach to being an effective security executive, based on measuring security by its ability to maintain its existing commitments; integrate controls into daily IT operations (prevent); put automated controls in place to variance before loss events (detect); reduce the percent of security incidents that result in loss events (detect); and successfully investigate and conclude security investigations.Attendees will learn about the key research findings:* That high performers have 5-8x higher operational and securityeffectiveness and efficiency measures* The 20% of IT controls that have 80% of the measurable benefits, andhow to implement and the prescriptive steps to take in order to achievedefined security results* The certain processes and controls that have shown catalytic andsustaining properties, meaning that the value they add demonstrablyexceeds the cost to implement, and report out on them. About the speaker: Gene Kim is the CTO and founder of Tripwire, Inc. In 1992, heco-authored Tripwire while at Purdue University with Dr. Gene Spafford.Since then, Tripwire has been adopted by more than 5,000 enterprisesworldwide. In 2004, Kim co-founded the IT Process Institute, which isdedicated to research, benchmarking and developing prescriptive guidancefor IT operations and security management and auditors. He alsoco-authored the "Visible Ops Handbook: Implementing ITIL in FourPractical And Auditable Steps" and was a principal investigator on theIT Controls Performance Study project, completed in 2006 Kim currentlyserves on the Advanced Technology Committee for the Institute ofInternal Auditors, and was part of the team that defined changemanagement best practices for the recently released IIA GlobalTechnology Guide "Change and Patch Management Controls: Critical forOrganizational Success."

Hyogon Kim, Real-Time Visualization of Network Attacks on High-Speed Links Sep 13, 2006

In this talk, we will see that malicious traffic flows such as denial-of-service attacks and various scanning activities can be visualized in an intuitive manner. A simple but novel idea of plotting a packet using its source IP address, destination IP address, and the destination port in a 3-dimensional space graphically reveals ongoing attacks. Leveraging this property, combined with the fact that only three header fields per each packet need to be examined, a fast attack detection and classification algorithm can be devised. About the speaker: Prof. Hyogon Kim is visiting Purdue University for the fall semester this year from Korea University, Seoul, Korea. He is an associate professor at Korea U., where he teaches Internet protocols and wireless communication. He received a Ph.D. from the University of Pennsylvania in 1996, and went on to Bell Communications Research (Bellcore, now Telcordia Technologies) to work on Internet protocols and architecture issues.

Ehab Al-Shaer, Ph.D., Toward Autonomic Security Policy Management Aug 23, 2006

The assurance of network security is dependent not only on the protocols but also on polices that determine the functional behavior of network security devices. Network security devices such as Firewalls, IPSec gateways, IDS/IPS operate based on locally configured access control policies. However, the complexity of managing security polices, particularly in enterprise networks, poses many challenges for deploying effective security. For example, security policies are usually configured in isolation from each other, even though they are not necessarily independent as they interact with each other to form the global security policy. As a result of such ad-hoc management, policy inconsistencies and network vulnerability are created. In addition security policy might grow in size causing a significant performance overhead in security devices. A major performance gain can be achieved if policies can be dynamic optimized to adapt to traffic properties (called traffic-aware policy optimization). This talk will explain these challenges and present the recent research results in the area of automated verification, and optimization of network security polices. About the speaker: Ehab Al-Shaer is an Associate Professor and the Director of Multimedia Networking Research Lab (MNLAB)in the School of Computer Science, Telecommunications and Information System at DePaul University.

Virgil D. Gligor, On the Evolution of Adversary Models for Security Protocols - from the Beginning to Sensor Networks Apr 26, 2006

Invariably, new technologies introduce new vulnerabilities which, in principle, enable new attacks by increasingly potent adversaries. Yet new systems are more adept at handling well-known attacks by old adversaries than anticipating new ones. Our adversary models seem to be perpetually out of date: often they do not capture adversary attacks enabled by new vulnerabilities and sometimes address attacks rendered impractical by new technologies. In this talk, I provide a brief overview of adversary models beginning with those required by program and data sharing technologies, continuing with those required by computer communication and networking technologies, and ending with those required by mobile ad-hoc and sensor network technologies. I argue that mobile ad-hoc and sensor networks require new adversary models (e.g., different from those of Dolev-Yao and Byzantine adversaries). I illustrate this with adversaries that attack perfectly sensible and otherwise correct protocols of mobile ad-hoc and sensor networks. These attacks cannot be countered with traditional security protocols as they require emergent security properties. About the speaker: Virgil D. Gligor received his B.Sc., M.Sc., and Ph.D. degrees from the University of California at Berkeley. He has been at the University of Maryland since 1976, and is currently a Professor of Electrical and Computer Engineering. He is an Editorial Board member of the ACM Transactions on Information System Security, IEEE Transactions on Dependable and Secure Computing, and IEEE Transactions on Computers. Over the past three decades, his research interests ranged from access control mechanisms, penetration analysis, and denial-of-service protection to cryptographic protocols and applied cryptography.

John Black, Recent Attacks on MD5 Apr 19, 2006

Cryptology is typically defined as cryptography (the construction of cryptographic algorithms) and cryptanalysis (attacks on these algorithms). Both are important, but the latter is more fun. Cryptographic hash functions are one of the core building blocks within both security protocols and other application domains. In the last few decades a wealth of these functions have been developed, but the two in most widespread usage are MD5 and SHA1. Recently, there has been a great deal of activity regarding the cryptanalysis of MD5. We survey the recent attacks on the MD5 hash function from the modest progress in the mid 90s to the startling recent results instigated by Xiaoyun Wang. We will look at the details of these attacks, some recent improvements, two applications, and discuss the current outlook on cryptographic hashing. About the speaker: John Black is an Assistant Professor of Computer Science at the University of Colorado at Boulder. Dr. Black's research interests lie primarily in cryptography and cryptanalysis, particularly in the construction of fast and provably-secure algorithms and in the analysis of cryptography applied to networks and computer systems. Dr. Black received his Ph.D. in Computer Science from the University of California at Davis in 2000. He is the recipient of an NSF CAREER award and a check from Donald Knuth for $2.56.

David Carroll, Identity Management Strategies and Integration Perspectives Apr 12, 2006

For large government agencies and corporations there can be significant value in the use of identity, access, and rights management infrastructures or IDM. The organizations investment in directory services, authorization services, rights management, and public key systems all combine to form a sometimes complex infrastructure. The products that are deployed may be based upon standards such as WS-Security, SAML, and X509.3 but many are still hampered by proprietary vendor implementation, lack of understanding of the capability of the technology as it relates to business process, or unwise architectural decisions. This seminar will focus on how the models for IDM are maturing and comment on how the urgency to deploy solutions changes when combined with service oriented architecture. The seminar will give practical examples from the experience of working within large scale infrastructures in both corporate and government environments. It will conclude with commentary on the IDM issues and solutions revolving around the largest government identity management effort to date About the speaker: David Carroll leads the Application Security Section for the MITRE Corporations Federal Systems Security Department in McLean, Virginia. Federal Systems Security is part of the MITRE INFOSEC Center and is charged with researching and defining architecture for government agencies that must interact through outreach to the public. He specializes in security architecture and has focused for the last 7 years in identity management, access management, and user provisioning systems. He currently advises the U.S. Department of Homeland Security Chief Information Security Officer and is particularly active in areas relating to Homeland Security Presidential Directive Twelve which mandates the use of a common identity credential for all U.S. government agencies. Mr. Carroll participates in several working groups including the Federal Bridge (FBCA) PKI working group. Prior to joining MITRE he was the information security architect for Marriott International and developed their identity and access management capabilities which service over 140,000 employees worldwide.

Minaxi Gupta, Spoofing-resistant Packet Routing for the Internet" Mar 29, 2006

The forgery of source IP addresses, called IP spoofing, is commonly exploited to launch damaging denial-of-service (DoS) attacks in the Internet. Currently proposed spoofing prevention approaches either focus on protecting only the target of such attacks and not the routing fabric used to forward spoofed packets, or fail under commonly occurring situations like path asymmetry. We will presents a hop-wise packet marking approach that equips the routers to drop spoofed packets close to their origination. Our approach has utmost concern for immediate deployability and simulations show that it dramatically reduces the amount of spoofing possible even under partial deployment. About the speaker: Minaxi Gupta is an Assistant Professor in the department of Computer Science at Indiana University (Bloomington, IN). Her research interests are in Computer Networks and Security, particularly in the performance aspects that fall in the intersection of these areas. Minaxi received a Ph.D. in Computer Science from Georgia Tech in 2004. She also holds an M.S. in Computer Science from Georgia Tech, and an M.Sc. in Physics from the Indian Institute of Technology Mumbai.

Julie Earp, Privacy Policies in Web-based Healthcare Mar 22, 2006

The Health Insurance Portability and Accountability Act of 1996 (HIPAA) has resulted in the presence of very descriptive privacy policies on healthcare websites. These policies are intended to notify users about the organization's privacy practices; however, they are typically not easy to read, leading few people to actually read them. Given the fact that these policies are not optional, but required by HIPAA, they should be presented in a clear and concise manner that encourages consumers to read them. At the present time, this is not the case. This seminar will present the preliminary results of our study that compares various ways to present privacy management information to healthcare consumers. The study involved an online experiment and survey of 993 Internet users. About the speaker: Julie Earp is an Associate Professor of Information Technology in the Business Management Department of the College of Management at NCSU. She is heavily involved with the cooperative electronic commerce initiative and The Privacy Place, both which involve the College of Management and the College of Engineering. Her research focuses on Internet security and privacy issues from several different perspectives, including data management, consumer values, policy, economics and law. The ultimate goal of her work is to demonstrate the need for supporting the early stages of the software lifecycle, specifically addressing the need for novel approaches to security and privacy coverage in web-based systems. Her research recently gained international recognition as the best paper awarded by the Organizational and Communication Information Systems (OCIS) division of the Academy of Management in 2003. An extended version of this award winning paper is available at IEEE Transactions on Engineering Management. Her involvement in educational activities has included her role as co-founder and co-director of the NCSU E-Commerce Studio. The Studio is a lab in which management and computer science graduate students collaborate in multi-disciplinary teams to develop Web-based e-commerce applications for industrial partners. In keeping with her research focus, students in the Studio are taught how to develop appropriate security and privacy policies as well as systems that are in compliance with those policies. She has also been a leader in developing the Information Technology curriculum under the Business Management degree at NCSU. She has initiated, designed, and taught several courses at both the undergraduate and graduate levels.

Marina Blanton, Dynamic and Efficient Key Management for Access Hierarchies Mar 08, 2006

Hierarchies arise in the context of access control whenever the set of users can be modeled as a set of partially ordered classes (i.e., represented as a directed graph). In such systems, a user that belongs to a particular class inherits privileges of all of its descendant classes. The problem of key management for an access hierarchy then consists in assigning a key to each class in the hierarchy so that keys for descendant classes can be obtained via an efficient key derivation process. We propose an efficient solution to this problem with a number of important properties, some of which are: a single key per class, local handling of changes to the hierachy, and provable security against collusion. Whereas many previous schemes had some of these properties, ours is the first that satisfies all of them. In addition, we give techniques to exponentially lower key derivation time for trees with only a contant increase in the space to store the hierarchy. About the speaker: Marina Blanton is a PhD candidate at Purdue University. She received her MS in CS from Purdue University in 2004 and MS in EECS from Ohio University in 2002. Her research interests lie in the areas of access control, applied cryptography, and privacy. More information is available at http://www.cs.purdue.edu/homes/mbykova.

Rafae Bhatti, A Policy Engineering Framework for Federated Access Management Mar 01, 2006

Federated systems are an emerging paradigm for information sharing and integration. Such systems require access management policies that not only protect user privacy and resource security but also allow scalable and seamless interoperation. Current solutions to distributed access control generally fail to simultaneously address both dimensions of the problem. This talk describes the design of a policy-engineering framework, called xFederate, for specification and enforcement of access management policies in federated systems. It has been designed from the perspectives of both security management and software engineering to not only allow specification of requirements for federated access management but also allow development of standardized policy definitions and constructs that facilitate policy deployment and enforcement in a federated system. The framework also includes the design of an administrative model targeted at access control policy administration in a decentralized environment. Two profiles of the policy language, namely a SAML profile and a WS-Policy profile, have been developed to integrate the framework with industry standards for federation and policy-based management in the emerging Web services paradigm. The talk will include an online demo of a research prototype that illustrates the use of xFederate as an enabling technology for secure Web services with applications in federated digital libraries and federated electronic healthcare management. About the speaker: Rafae Bhatti is a PhD candidate in the Department of Electrical and Computer Engineering and affiliated with the Center for Education and Reserach in Information Assurance and Security (CERIAS) at Purdue University. His research interests include information systems security, with emphasis on design and administration of access management policies in distributed systems. In his M.S. thesis research at Purdue, he developed an XML-based policy specification framework for distributed access control. His PhD research focuses on the access management problems posed by the emerging federated paradigm of information sharing and collaboration, and on specification of XML-based security protocols for Web-based information systems. His work on XML-based access control framework for the Role Based Access Control (RBAC) model have recently been cited by the OASIS consortium in their official announcement of the RBAC standard.

Mike Burmester, Provable security in mobile ad hoc networks Feb 15, 2006

Mobile ad hoc networks (MANETs) are collections of wireless mobile nodes with links that are made or broken in an arbitrary way. Communication is achieved via routes whose node relay packets. Several routing algorithms have been proposed in the literature. These focus mainly on efficiency with security relegated to weak adversary models. In this talk we consider the security of distributed MANET applications in malicious adversary models. We model a MANET by a stochastic finite state machine that is subject to mobility, medium and markovian constraints and describe an adversary structure that addresses the malicious attacks that are particular to MANETS (wormhole attacks, Sybil attacks, packet dropping, selfishness). We then show how the traditional cryptographic framework for provable security can be adapted to this particular adversary structure. Finally we consider two complementary approaches that can be used to achieve provably secure routing in our adversary model: a reactive approach that traces malicious behavior and a proactive approach that tolerates malicious behavior.

Brian Carrier, Categories of Digital Forensic Investigation Techniques Feb 08, 2006

This talk examines formal concepts of digital forensic investigations. To date, the field has had an applied focus and little theory exists to formally define analysis techniques and requirements. This work defines an extended finite state machine (FSM) model and uses it to describe a computer's history, which contains the primitive and abstract states and events that existed and occurred. Using this model, categories of analysis techniques can be defined. This talk describes the model, describes the categories of analysis techniques, and compares the existing tools to the analysis technique categories. About the speaker: Brian Carrier is the author of \"File System Forensic Analysis\" and several digital forensic analysis tools, including The Sleuth Kit and the Autopsy Forensic Browser. He is completing his Ph.D. in computer science at Purdue University. Previously, Brian was a Research Scientist at @stake in Boston, MA, and the lead for the @stake Response Team and Digital Forensic Labs. Brian has been involved with the European Commission\'s CTOSE project on Digital Evidence, is a member of the Honeynet Project, a referee for the Journal of Digital Investigation, and on the committees of several conferences, workshops, and technical working groups.

Paul Thompson, Semantic Attacks and Security Jan 25, 2006

Attacks on computer and other networked systems can be categorized as physical, syntactic and semantic. Physical attacks seek to destroy hardware, while syntactic attacks, such as computer worms and viruses, target the network infrastructure. Semantic attacks are directed at the mind of the user of a computer system, or, more generally, any decision process in an automated system. For example, a false, or misleading, discussion group posting which leads readers of the posting to become victims of a pump-and-dump scheme, whereby the price of a company About the speaker: Paul Thompson received his Ph.D. from the University of California, Berkeley, in 1986. He is currently a research professor in Dartmouth College

Jean Camp, Net Trust: Identification Through Social Context Jan 18, 2006

In the nineties the disconnection between physical experience and the digital networked experience was celebrated - individuals are said to move into cyberspace, become virtual and leave the constraints of the physical realm. The increase in fraud, difficulties in securing email, and increasing prevalent browser-based attacks illustrate that the lack physical signaling information can also be costly. I introduce a trust that evaluation system, Net Trust. The trust evaluation system offered in Net Trust builds on the technical construction of networks of trust, reputation systems, and social browsing. Net Trust is explicitly a socio-technical solution; the solution employs a user About the speaker: Professor L. Jean Camp\'s core interest is in the interaction of technical, financial and social trust.

Simson Garfinkel, Cross-Drive Forensic Analysis Jan 11, 2006

This talk introduces cross-drive analysis (CDA), a new approach for performing analysis of forensic data sets that are too large or complex to be analyzed with today's existing tools. CDA works by performing systematic information extraction and cross-correlation across an entire data set. CDA was used to analyze 182 disk drives acquired on the secondary market; it automatically identified drives containing a high concentration of confidential financial records and three pairs of drives, each previously used by the same organization. CDA shows strong promise in allowing forensic examiners to prioritize their work and in automatically identifying members of preexisting social networks. About the speaker: Simson L. Garfinkel is a postdoctoral fellow at the Center for Research on Computation at Society at Harvard University and an instructor at the Harvard Extension School, where he teaches courses on computer security and application design. He is also a founder of Sandstorm Enterprises, a computer security firm that develops advanced computer forensic tools used by businesses and governments to audit their systems.

Jelena Mirkovic, Clouseau: A practical IP spoofing defense through route-based filtering Dec 07, 2005

IP spoofing accompanies many malicious activities and is even means for performing reflector DDoS attacks. Route-based filtering (RBF) enables a router to filter spoofed packets based on their incoming interface - this information is stored in an incoming table. Packets arriving on the expected incoming interface for their source address are considered legitimate, while all the other packets are filtered as spoofed. Past research has shown that RBF can be very effective when deployed at the vertex cover of the Internet AS-map (about 1500 ASes) but no practical approach has been proposed for incoming table construction. We first show that RBF achieves high effectiveness even if the number of deploying points is very small (30 chosen deployment points reduce the amount of the spoofed Internet traffic to 5%). We further show that completeness of the incoming tables is critical for filtering effectiveness - partially full tables are as good as empty. This implies that routers cannot rely on reports of a few participating domains to build their incoming tables, but instead must devise means of accurately "guessing" incoming interface information for all traffic they see. Their guessing strategy must quickly react to offending traffic and determine with high accuracy whether the reason for the offense was a route change (in which case incoming interface information must be updated) or spoofing. We next propose a protocol called Clouseau which builds accurate incoming tables at RBF routers, and keeps these tables up to date in face of frequent route changes. Clouseau infers incoming table information by applying randomized drops to offending TCP traffic and observing its retransmission behavior. No communication is required with packet sources or other RBF routers, which makes Clouseau suitable for partial deployment. The inference process is further resilient to subversion by an attacker who is familiar with the design of Clouseau.

Stanislaw Jarecki, Secret Handshakes Nov 30, 2005

Secret Handshake is an authentication protocol with non-standard and strong anonymity property: Namely, the secrecy of the *affiliations* (i.e. the certificates) of party A who engages in this authentication protocol with party B will be protected against any B* (i.e. a malicious party which pretends to be B) who does not meet A's authentication criteria. This strong secrecy and anonymity protection turns out to be possible, and quite efficiently so, based on various standard cryptographic assumptions. The talk will give an overview of the problem, the various solutions, and the several efficiency and security issues involved in making such anonymous authentication schemes practical. About the speaker: Stanislaw Jarecki is a Professor in the Department of Computer Science at the University of California, Irvine. He is working on cryptography and fault tolerant distributed protocols. He received his Ph.D. in Computer Science at MIT in 2001.

Between MIT and UCI, Stanislaw worked as a researcher at Intertrust and then as a postdoc in the cryptography and security group at Stanford. His current work includes threshold protocols, affiliation-privacy in authentication protocols, robust cryptographic protocols, and theoretical issues like secure 2-party computation.

Shouhuai Xu, Privacy-preserving Policy-driven Access Control with Mixed Credentials Nov 16, 2005

Access control in decentralized systems is an important problem that has not been fully understood, except perhaps that it should be based on credentials. There are mainly two research approaches towards this goal: one is to pursue powerful individual credentials yet without necessarily considering flexible access control policies, the other is to consider flexible policies yet without necessarily accommodating the useful credential schemes that have become available. This paper proposes a unified approach that simultaneously consider flexible policies and useful credentials. A first realization of this approach is the notion of assembly signatures (and identifications), which are: (1) privacy-preserving, meaning that the access requestor's privacy is ensured; (2) policy-driven, meaning that the validity of a signature is with respect to a given access control policy; (3) ``mixed credentials"-based, meaning that a signature is constructed out of various anonymous and non-anonymous credentials. (This is a joint work with Moti Yung) About the speaker: Shouhuai Xu is an assistant professor in the Department of Computer Science, University of Texas, San Antonio. He earned his PhD in computer science in 2000 from Fudan University, China.

Anna Squicciarini, Privacy and anonymity in Trust Negotiations". Nov 09, 2005

Trust negotiation is an emerging approach for establishing trust in open systems, where sensitive interactions may often occur between entities with no prior knowledge of each other. Although several proposals today exist of systems for the management of trust negotiation, none of them provides a comprehensive approach to the problem of privacy preservation. Trust negotiation systems, however, by their very nature may represent a threat to privacy. Credentials, exchanged during negotiations, often contain sensitive personal information that thus needs to be selectively released. As we believe that trust negotiation systems must effectively address privacy issues to be widely acceptable, we have investigated privacy in the context of trust negotiations. In this talk, we will propose the main results obtained so far in the area of trust negotiation as part of the Ph.D. activity. We propose a set of privacy preserving features to be included in any trust negotiation system, such as the support for the P3P standard, as well as a number of innovative features such as a novel format to encode digital credentials specifically designed for preserving privacy. Finally, we illustrate techniques for supporting anonymous trust negotiations as part of a privacy-preserving trust negotiations, to carry on trust negotiations without revealing identity related information. About the speaker: Anna Cinzia Squicciarini is a PhD Student at the University of Milan, Italy. She received a degree in Computer Science from the University of Milan in July 2002 with full marks.

Dr. Angelos D. Keromytis, Toward Self-healing Software Oct 19, 2005

As systems grow in size and complexity, our ability to protect them through manual intervention or static defenses degrades. We believe that, in addition to proper design principles and proactive mechanisms, automated reactive approaches must be employed to close the gap in the attacker vs. defender capabilities. Toward this goal, we have been examining the possibility of software systems that self-diagnose and repair themselves in the presence of previously unknown attacks and failures, with minimal or no human intervention. In this talk, I will discuss our research in self-healing software systems. I will introduce the concepts of "micro-speculation" and "error virtualization", which can be combined to provide a generic mechanism for dealing with low-level software failures and vulnerabilities. I will describe the use of these techniques in two system prototypes of self-healing software that address such vulnerabilities: the Worm Vaccine architecture and STEM (Selective Transactional EMulation). I will close the talk with a discussion of our preliminary work toward software Application Communities, groups of identical instances of an application that cooperate to improve their collective security. About the speaker: Angelos Keromytis is an Assistant Professor of Computer Science at Columbia University. He received his MS and PhD from the University of Pennsylvania, and his BS (all in Computer Science) from the University of Crete, in Greece.

Dan Massey, Securing the Internet's Domain Name System Oct 05, 2005

This talk considers security challenges facing the Internet's Domain Name System (DNS). The DNS is one of the most widely used and least secure Internet systems. Viirtually every Internet application relies on the DNS to convert names into IP addresses and the DNS provides a wide range of other critical mappings such as identifying mail servers and locate services. But despite its importance, the original DNS design gave very little thought to security and a variety of misdirection and denial of service attacks are possible. For example, a web browser relies on the DNS to convert www.purdue.edu into an IP address. The DNS supplies the web browser with an IP address (more precisely an "A" resource record set) such as 129.82.100.64 (is this address correct?). If this address is wrong, the browser will be directed to the wrong site. If the DNS fails to return a response, the browser will not be able to load the desired web page. Currently, both the operational and research communities are making considerable efforts to improve DNS security. After nearly a decade of development, the IETF has standardized DNS Security Extensions that add public key authentication into the DNS. The hierarchical structure of the DNS is leveraged to authenticate public keys, keys can be managed offline, and the signatures allow a resolver to authenticate a response. However several open issues remain, including key revocation, support for dynamic updates, resolver security policies, incremental deployment, and commercial challenges. The DNS Security Extension enable a number of new techniques, but basic problems on denial of service remain. The research community has largely focused on denial of service attacks against critical top level servers could potentially cause considerable damage to the DNS service. This has led to proposals for replacing the DNS tree with a distributed hash table attacking a few critical top level servers. This talk will argues that, despite some major flaws, the DNS Security Extensions provide the necessary tools to build a robust and secure DNS. By using these tools appropriately, a wholesale replacement of the DNS system by other approaches can and should be avoided. About the speaker:

Ting Yu, A Framework for Identifying Compromised Nodes in Sensor Networks Sep 21, 2005

Sensor networks are vulnerable to physical attacks. Once a node's cryptographic key is compromised, an attacker may completely impersonate it, and introduce arbitrary false information into the network. Most existing techniques focus on detecting and tolerating false information introduced by compromised nodes. They cannot pinpoint exactly where the false information is introduced and who is responsible for it. We propose an application-independent framework for identifying compromised sensor nodes. In this framework, sensor nodes may conceptually observe the activity of each other following the deployment topology of a sensor network. An alert is generated if a node observes an abnormal activity. Such alerts are collected by the base station, which further reason and finally identify compromised nodes. We develop efficient and accurate reasoning algorithms that can effectively deal with collusion and local majorities. Our algorithms are optimal in the sense that they identify the largest number of compromised nodes without introducing false positives. About the speaker: Ting Yu received his PhD from the University of Illinois at Urbana-Champaign in 2003. He is currently an assistant professor in the Department of Computer Science, North Carolina State University. His research interests include trust negotiation and management, privacy policy specification and enforcement, and data privacy.

Peter Bajcsy, Toward Hazard Aware Spaces: Knowing Where, When and What Hazards Occur Sep 14, 2005

While considering all existing hazards for humans due to (a) natural disastrous events, (b) failures of human hazard attention or (c) intentional harmful behaviors of humans, we address the problem of building hazard aware spaces (HAS) to alert innocent people. We have researched and developed components of a prototype HAS system for detecting fire using wireless "smart" micro electro-mechanical systems (MEMS) sensors, such as, the MICA sensors, and spectral cameras, for instance, thermal infrared (IR), visible spectrum and multi-spectral cameras. Within this context, my presentation overviews technical challenges and prototype scientific solutions to (1) robotic sensor deployment, (2) localization of sensors and objects, (3) synchronization of sensors and cameras, (4) calibration of spectral cameras and sensors, (5) proactive camera control, (6) hazard detection, (7) human alert, (8) hazard confirmation, and (9) hazard understanding and containment. The work presented will also include theoretical and practical limitations that have to be understood when working with novel technologies. http://www.ncsa.uiuc.edu/people/pbajcsy/ About the speaker: Peter Bajcsy has earned his Ph.D. degree from the Electrical and Computer Engineering Department, University of Illinois at Urbana-Champaign, IL, 1997, M.S. degree from the Electrical Engineering Department, University of Pennsylvania, Philadelphia, PA, 1994 and Diploma Engineer degree from the Electrical Engineering Department, Slovak Technical University, Bratislava, Slovakia, 1987.

We'll discuss the most common types of attacks and how to defend against them, both on a code, application, and network design level.

Himanshu Khurana, Minimizing Trust Liabilities in Secure Group Messaging Infrastructures Aug 31, 2005

Large-scale collaborative applications are characterized by a large number of users and other processing end entities that are distributed over geographically disparate locations. Therefore, these applications use messaging infrastructures that scale to the application needs and enable users to process messages without concern for message transmission and delivery. Widespread use of these infrastructures is hindered by the need for scalable security services; viz., services for confidentiality, integrity, and authentication. Current solutions for providing security for these systems use trusted servers (or a network of servers), which consequently bear significant trust liabilities of maintaining confidentiality, integrity, and authentication of messages and keys that are processed by the servers. In this talk we look at current approaches for secure messaging in three commonly used messaging infrastructures: email, group communication, and publish/subscribe. We then show how novel encryption techniques can be used to minimize trust liabilities in these infrastructures in a scalable manner. We are in the process of developing prototypes of our solutions. We will discuss the prototype designs and present some initial experimentation results. About the speaker: Dr. Himanshu Khurana received his MS from the University of Maryland in 1999, and his PhD from the University of Maryland in 2002. He worked as a postdoctoral research at the Institute for Systems Research, University of Maryland from 2002 to 2003.

Sheng Zhong, PrivacyEnhancing k-Anonymization of Customer Data Apr 27, 2005

In order to protect individuals' privacy, the technique of k-anonymization has been proposed to de-associate sensitive attributes from the corresponding identifiers. In this work, we provide privacy-enhancing methods for creating k-anonymous tables in a distributed scenario. Specifically, we consider a setting in which there is a set of customers, each of whom has a row of a table, and a miner, who wants to mine the en- tire table. Our objective is to design protocols that allow the miner to obtain a k-anonymous table representing the customer data, in such a way that does not reveal any extra information that can be used to link sensitive attributes to corresponding identifiers, and without requiring a central authority who has access to all the original data. We give two different formulations of this problem, with provably private solutions. Our solutions enhance the privacy of k-anonymization in the distributed scenario by maintaining end-to-end privacy from the original customer data to the final k-anonymous results. About the speaker: Sheng Zhong received his Ph.D in computer science from Yale University in the year of 2004. He holds an assistant professor position at SUNY Buffalo and is currently on leave for postdoctoral research at the Center for Discrete Mathematics and Theoretical Computer Science (DIMACS).

Marianne Winslett, Traust and PeerTrust2: Applying Trust Negotiation to Real Systems Apr 20, 2005

Automated trust negotiation is an approach to authorization for open systems, i.e., systems where resources are shared across organizational boundaries. Automated trust negotiation enables open computing by assigning an access control policy to each resource that is to be made accessible to "outsiders"; an attempt to access the resource triggers a trust negotiation, consisting of the iterative, bilateral disclosure of digital credentials and related information. In our recent work in applying the TrustBuilder system for trust negotiation to real-world systems, we have encountered the need to make trust negotiation facilities available to legacy peers, which has led to the development of the Traust system. We have also encountered the need to include helpful third parties in the negotiation process, such as credential wallets, remote authorization servers, and brokers. PeerTrust2 is our effort to design a language that allows us to reason about trust negotiations involving helpful third parties, while supporting exposure control, delegation, proof hints, declarations of purpose, sensitive policies, and other potentially useful aspects of access control. In this talk, I will demonstrate Traust and describe its internal design, and then describe PeerTrust2.

Brian Carrier, Defining a Digital Forensic Investigation Apr 06, 2005

Digital investigations have occurred in some form or another for many years, yet there is no scientific model of the process. After all, there are multiple ways and sequences in which evidence may be found. An investigator does not necessarily need a model to solve a case, but a scientific model is useful for developing investigation tools and technology because it allows us to define requirements and identify what areas need more attention. Further, there are guidelines for entering technical evidence into a U.S. court that may require the technical procedure to be published and have known error rates. In this talk, I will present an overview of existing process models that an investigator can use. I will then present our initial findings on a more scientific model that is based on how digital evidence is created and will show how it can be applied to the process models used by practitioners. Our event-based model allows us to more clearly define requirements for investigation tools, which will help in the development and testing process. About the speaker: Brian Carrier is a Research Assistant at CERIAS and a Computer Science Ph.D. candidate. Previously, Brian was a Research Scientist at @stake in Boston, MA, and the lead for its incident response team and digital forensic lab.

Helen J. Wang, Vulnerability-Driven Network Filters for Preventing Known Vulnerability Attacks Mar 30, 2005

Software patching has not been an effective first-line defense preventing large-scale worm attacks, even when patches had long been available for their corresponding vulnerabilities. Generally, people have been reluctant to patch their systems immediately, because patches are perceived to be unreliable and disruptive to apply. To address this problem, we propose a first-line worm defense in the network stack, using shields -- vulnerability-specific, exploit-generic network filters installed in end systems once a vulnerability is discovered, and before the patch is applied. These filters examine the incoming or outgoing traffic of vulnerable applications, and drop or correct traffic that exploits vulnerabilities. Shields are less disruptive to install and uninstall, easier to test for bad side effects, and hence more reliable than traditional software patches. Further, shields are resilient to polymorphic or metamorphic variations of exploits In the Shield project, we're showing that this concept is feasible by implementing a prototype Shield framework that filters traffic at the transport layer. We have designed a safe and restrictive language to describe vulnerabilities as partial state machines of the vulnerable application. The expressiveness of the language has been verified by encoding the signatures of a number of known vulnerabilities. Our evaluation provides evidence of Shield's low false positive rate and impact on application throughput. An examination of a sample set of known vulnerabilities suggests that Shield could be used to prevent exploitation of a substantial fraction of the most dangerous ones. About the speaker: Helen J. Wang is a researcher in the Systems and Networking research group at Microsoft Research, Redmond, WA.

David Evans, Where's the FEEB? Effectiveness of Instruction Set Randomization Mar 09, 2005

Instruction Set Randomization (ISR) has been proposed as a promising defense against code injection attacks. It defuses all standard code injection attacks since the attacker does not know the instruction set of the target machine. A motivated attacker, however, may be able to circumvent ISR by determining the randomization key. In this talk, I will describe a remote attack for determining an ISR key using an incremental guessing strategy and present a method for injecting a worm in an ISR-protected network. The attack is plausible under a variety of realistic conditions and can infect an ISR-protected server in under 6 minutes. Our results provide insights into properties necessary for ISR implementations to be secure and suggest ways to improve to ISR designs.

Florian Buchholz, Using process labels to obtain forensic and traceback information Mar 02, 2005

Much of the research in computer security, especially in digital forensics and intrusion detection, is concerned with retrieving and analyzing the information that is present on a system. In my talk I will analyze what kind of information is actually desired by a forensic investigator and examine if these needs can be fulfilled by today's operating systems. Some of the desired information is currently not present in many systems and I will make suggestions on how to supply more relevant audit data on a system and increase its quality. The second part of my talk will focus on two particular difficult categories of information that a forensic investigator might desire: user influence and origin information. I will present a model that allows a system to bind arbitrary information in the form of labels to its principals and then propagate the labels as information is exchanged among them. I will demonstrate the usefulness of the model with various case studies and discuss a proof-of-concept implementation. While my work is motivated and aimed primarily at digital forensic investigations, it has applications in other areas of computer science, in particular network traceback, intrusion detection, and access control. About the speaker: Florian Buchholz is a graduate student in the department of Computer Sciences at Purdue University. He holds a Diplom in Informatics from the Technische Universitaet Braunschweig, Germany and a Masters degree in computer science from Purdue University.

Wenke Lee, Architectural Considerations for Anomaly Detection Feb 09, 2005

The most commonly used intrusion detection system (IDS) performance metrics are detection rate and false alarm rate. From a usability point of view, a very important measurement is Bayesian detection rate, which indicates how likely there is an intrusion when the IDS outputs an alert. It depends on detection rate, false alarm rate, and base rate (the prior probability of intrusion). Typically, an anomaly detection system has a low Bayesian detection rate because it has a non-zero false alarm rate and the base rate in the target environment is very low. We argue that we need better system architecture to improve Bayesian detection rate. The main objective is to increase the base rate of data stream analyzed by complex detection modules. The general principle is to use layered architecture. One approach is to use a cascade of successively more complex detection modules. We show that base rate increases from one layer to the next. In many cases, the overall false alarm rate of the cascade can be very low. We describe a worm detection system with cascade architecture. In DSC, the lower layer module identifies hosts with

Vitaly Shmatikov, Obfuscated Databases: Definitions and Constructions Feb 02, 2005

I will present some new definitions and constructions for privacy in large databases. In contrast to conventional privacy mechanisms that aim to prevent any access to individual records, our techniques are designed to prevent indiscriminate harvesting of information while enabling some forms of legitimate access. We start with a simple construction for an obfuscated database that is provably indistinguishable from a black-box lookup oracle (in the random oracle model). Some attributes of the database are designated as "key," the rest as "data." The database behaves as a lookup oracle if, for any record, it is infeasible to extract the data fields without specifying the key fields, yet, given the values of the key fields, it is easy to retrieve the corresponding data fields. We then generalize our constructions to a larger class of queries, and achieve a privacy property we call "group privacy." It ensures that users can retrieve individual records or small subsets of records from the database by identifying them precisely. The database is obfuscated in such a way that queries returning a large subset of records are computationally infeasible. This is joint work with Arvind Narayanan.

Keith Frikken, Hidden Access Control Policies with Hidden Credentials Jan 19, 2005

In an open environment such as the Internet, the decision to collaborate with a stranger (e.g., by granting access to a resource) is often based on the characteristics (rather than the identity) of the requester, via digital credentials: Access is granted if Alice's credentials satisfy Bob's access policy. The literature contains many scenarios in which it is desirable to carry out such trust negotiations in a privacy-preserving manner, i.e., so as minimize the disclosure of credentials and/or of access policies. Elegant solutions were proposed for achieving various degrees of privacy-preservation through minimal disclosure. We present efficient protocols that protect both sensitive credentials and sensitive policies. That is, Alice gets the resource only if she satisfies the policy, Bob does not learn anything about Alice's credentials (not even whether Alice gained access or not), and Alice learns neither Bob's policy structure nor which credentials caused her to gain access. About the speaker: Keith Frikken is a doctoral student in computer science at Purdue University. His research interests are are in security and databases. His specific interests in security include: secure protocols, privacy, and access control.

Cristina Nita-Rotaru, Survivable routing in wireless ad hoc networks Jan 12, 2005

In an ad hoc wireless network nodes not in direct range communicate via intermediate nodes. Thus, a significant concern is the ability to route in the presence of Byzantine failures which include nodes that drop, fabricate, modify, replay, or mis-route packets in an attempt to disrupt the routing service. In this talk we will present ODSBR, our on-demand Byzantine resilient routing protocol for ad hoc wireless networks. The protocol relies on an adaptive probing technique that detects a malicious link after $log n$ faults have occurred, where $n$ is the length of the path. Problematic links are avoided by using a weight-based mechanism that multiplicatively increases their weights and by using an on-demand route discovery protocol that finds a least weight path to the destination. Our protocol bounds the amount of damage that an attacker or a group of colluding attackers can cause to the network. We demonstrate through simulation the effectiveness of ODSBR, in mitigating Byzantine attacks. Our analysis of the impact of these attacks versus the adversary's effort gives insights into their relative strengths, their interaction and their importance when designing secure routing protocols. Finally, we show how the technique used by ODSBR can be applied to hybrid wireless networks consisting of cellular and ad hoc 802.11 wireless networks.

Dennis Fetterly, Using Statistical Analysis to Locate Spam Web Pages Dec 08, 2004

Commercial web sites are more dependant than ever on being placed prominently within the result pages returned by a search engine to be successful. "Spam" web pages are web pages that are created for the sole purpose of misleading search engines and misdirecting traffic to target sites. Certain classes of spam pages, in particular those that are machine-generated, diverge in some of their properties from the properties of web pages in general. As a result, these pages can be identified through statistical analysis. We have examined a variety of such properties, including linkage structure, page content, and page evolution, and have found that outliers in the statistical distributions of these properties are predominantly caused by web spam. Joint work with Mark Manasse and Marc Najork. About the speaker: Dennis Fetterly is a Technologist in Microsoft Research\'s Silicon Valley lab, which he joined in May, 2003. His research interests include a wide variety of web related topics including web crawling, the evolution and clustering of pages on the web, and identifying spam web pages.

William Winsborough, Attribute-Based Access Control Dec 01, 2004

Basing authorization on attributes of the resource requester provides flexibility and scalability that is essential in the context of large distributed systems. Logic programming provides an convenient, expressive, and well-understood framework in which to work with authorization policy. This talk will summarize an attribute-based authorization framework built on logic programming: RT, a family of Role-based Trust-management languages. It will then discuss efficient and effective evaluation of RT policies that are stored in a distributed manner. After discussing these basics, the talk will consider the problem of assessing authorization policies with respect to the vulnerability of resource owners to a variety of security risks to which they are exposed by delegations to other principals, risks such as undesired authorizations and unavailability of critical resources. We will consider several such properties of RT policies, many of which we will see can be decided efficiently. For other properties, we will see that the complexity depends on the subset of RT in which the policy is expressed. This part of the talk will conclude by discussing some prospects for continued research in this area. Finally, the talk will visit the problem of using attribute credentials to obtain access when the credentials and their contents may themselves be private. Trust negotiation, a simple approach to this problem, will be introduced, as well as an intuitive and useful security property formalizing the protection of private credentials. This research was funded by DARPA and the NSF. About the speaker: William H. Winsborough is a Research Associate Professor in the Center for Secure Information Systems at George Mason University.

Indrakshi Ray, An Anonymous Fair-Exchange E-Commerce Protocol Nov 17, 2004

Many business transactions over the Internet involve the exchange of digital products between two parties -- electronic mails, digital audio and video, electronic contract signing and digital signatures, to name a few. Often these transactions occur between players that do not always have identifiable place of doing business and hence do not trust each other. Consequently, there exists ample scope for any of the parties involved, to misbehave and gain advantage over the other party. To overcome this problem researchers have proposed protocols that ensure fairness, that is, no party can gain an advantage even if the party misbehaves. Most works in this area focus on gathering evidence during the protocol execution that is used later, in case of a dispute. The actual handling of the dispute is done manually, after the protocol execution, and is outside the scope of the protocol. However, in an electronic commerce environment, where the merchants and customers may disappear quickly, such "after-the-fact" protection may be inadequate. In this work we propose an e-commerce protocol for trading digital products over the Internet. The novel features of our protocol include: (1) ensuring fair exchange, (2) not requiring manual dispute resolution in case of unfair behavior by any party, (3) assuring each party that the item he is about to receive is indeed the correct one, (4) not requiring the active involvement of a trusted third party unless a problem occurs, and (5) ensuring anonymity for the customer.

James Joshi, GTRBAC: A Generalized Temporal Role Based Access Control Model Nov 10, 2004

A key issue in computer system security is to protect information against unauthorized access. Emerging workflow-based applications in healthcare, manufacturing, the financial sector, and e-commerce inherently have complex, time-based access control requirements. To address the diverse security needs of these applications, a Role Based Access Control (RBAC) approach can be used as a viable alternative to traditional discretionary and mandatory access control approaches. The key features of RBAC include policy neutrality, support for least privilege, and efficient access control management. However, existing RBAC approaches do not address the growing need for supporting time-based access control requirements for these applications. In this talk, I will present a Generalized Temporal Role Based Access Control (GTRBAC) model that combines the key features of the RBAC model with a powerful temporal framework. The proposed GTRBAC model allows specification of a comprehensive set of time-based access control policies, including temporal constraints on role enabling, user-role and role-permission assignments, and role activations. The model provides an event-based mechanism for providing context based access control, as well as expressing dynamic access control policies, which are crucial for developing secure workflow-based enterprise applications. I will discuss various design guidelines for managing complexity of policy specification as well as an XML-based GTRBAC policy specification language.

Abe Singer, Towards Mining Syslog Data Nov 03, 2004

Syslog is the primary source of information about intrusion-related activity on a Unix system. Searching for known messages and patterns in syslog data is easy to do, and many tools are available for doing so. However, information and patterns that are not already "known" -- those that have not been seen or derived already, may provide even more information about attacks and intrusions. Data mining techniques can help us discover and analyze that information, but, the general lack of structure in syslog data makes it impossible to apply these techniques directly to the data. To address the problem, we are researching methods of generating patterns from an archive of system logs which can uniquely identify syslog messages by the variant and invariant elements of the messages. Once syslog messages can be uniquely identified, data mining techniques for use in intrusion detection or forensic analysis will be far more useful. About the speaker: Abe Singer is a Computer Security Researcher with the Security Technologies Group at the San Diego Supercomputer Center. Involved with both operational security and research, his work involves growing SDSC logging infrastructure and analysis capabilities, participating in incident response and investigation, and working with the Teragrid Security Working Group.

In addition to his work at SDSC, Mr. Singer is an occasional consultant and expert witness, and runs the San Diego Regional Information Watch (www.sdriw.org).

Ari Takanen, Robustness testing - black-box testing for software security Oct 27, 2004

The robustness testing method is based on systematic creation of a very large number of communication protocol messages containing exceptional data elements and structures simulating malicious attacks or corrupted traffic. The method provides a proactive way of assessing software robustness and security. Robustness here is defined as the ability of software to tolerate exceptional input and stressful environment conditions. A piece of software which is not robust fails when facing such circumstances. In the worst case, a malicious intruder can take advantage of robustness shortcomings to deny service from authentic users or to compromise the system running the piece of software. As part of one robustness testing usage scenario, namely security assessment, also the communication process from security vulnerability discovery to vulnerability elimination will be explored. This research was originally initiated in PROTOS project at the University of Oulu, Finland. About the speaker: Ari Takanen, founder and CEO of Codenomicon has since 1998 been researching information security issues in security-critical environments. His work at Codenomicon and at the OUSPG (University of Oulu) aims to ensure that new technologies are accepted by the general public by providing means of measuring and ensuring quality in networked software.

His company, Codenomicon Ltd. provides automated tools with a systematic approach to test a multitude of interfaces on mission critical software.

Dan Thomsen, Information Flow Analysis in Security Enhanced Linux Oct 13, 2004

Most people now realize that computer security is hard. However, many people do not realize that creating a correct security policy is hard. Creating an accurate security policy is on the order of complexity of developing software in general. In particular how can you show the policy is correct? The focus of this seminar is to look at tools and techniques for showing that the mandatory security policy based on type enforcement meets its objectives. The approach breaks down the security policy objectives so that they can be studied in terms of information flows. The policies are specified for the Security Enhanced Linux type enforcement mechanism. Type enforcement and mandatory access control will also be discussed.

Gail-Joon Ahn, Secure Information Sharing within a Collaborative Environment Sep 15, 2004

The Internet is uniquely and strategically positioned to address the needs of a growing segment of population in a very cost-effective way. It provides tremendous connectivity and immense information sharing capability which the organizations can use for their competitive advantage. Several organizations have transited from their old and disparate business models based on ink and paper to a new, consolidated ones based on digital information on the Internet. However, information sharing on the Internet usually occurs in broad, highly dynamic network-based environments, and formally accessing the resources in a secure manner poses a difficult challenge. Balancing the competing goals of collaboration and security is difficult because interaction in collaborative systems is targeted towards making people, information, and resources available to all who need it, whereas information security seeks to ensure the integrity of these elements while providing it only to those with proper authorization. As organizations implement information strategies that call for sharing access to resources in the networked environment, mechanisms must be provided to protect the resources from adversaries. This talk addresses the issue of how to advocate selective information sharing in collaborative systems through access control schemes while minimizing the risks of unauthorized access proposing a delegation framework. It also introduces a systematic approach to specify delegation and revocation policies using a set of rules. The feasibility of the proposed framework is also discussed through policy specification, enforcement, and a proof-of-concept implementation. About the speaker: Gail-Joon Ahn is an assistant professor of Software and Information Systems Department at University of North Carolina at Charlotte and a coordinator of Laboratory of Information Integration, Security and Privacy which has been designated as a Center of Academic Excellence in Information Assurance Education by National Security Agency.

Jason Crampton, Administrative Scope and Role-Based Administration Sep 08, 2004

Role-based access control (RBAC) has received considerable attention in recent years, resulting in several important theoretical models and increasing use in commercial products. Nevertheless, role-based administration, the use of role-based techniques to control RBAC systems, has been less widely studied. We will consider the problem of controlling the propagation of authorization information in computer systems in general, and in role-based systems in particular. We will then introduce the concept of administrative scope, an intuitive notion corresponding to the set of role(s) that can be controlled by a given role, and demonstrate how this can be used as the fundamental unit in the development of a family of administrative models for RBAC systems. We compare the characteristics of these models with the well-known ARBAC97 administrative model. We conclude by discussing how administrative scope can be used to provide an administrative framework for more complex RBAC models. About the speaker: Jason Crampton is a lecturer in the Information Security Group at Royal Holloway, University of London. His main research interests are role-based access control, with particular emphasis on role-based administration, authorization constraints, and the use of partial order theory in access control and information security.

Gary McGraw, Building Secure Software Jan 10, 2001

Computer security takes on more importance as commerce becomes e-commerce and business embraces the Net. However, little progress has been made in the security field, especially when vendor technology is considered. Popular press coverage of computer security orbits around basic technology issues such as what firewalls are, when to use the DES encryption algorithm, which anti-virus product is best, or how the latest email-based attack works. The problem is, many security practitioners don't know what the problem is. It's the software! Internet-enabled software applications, especially custom applications, present the most common security risk encountered today, and are the target of choice for real hackers. This talk is all about software security risk and how to manage it. The trick is to begin early, know your threats (including language-based flaws and pitfalls), design for security, and subject your design to thorough objective risk analyses and testing. This talk covers material that software practitioners, including architects and languages researchers, can use to avoid security problems and produce more secure Internet-based code. About the speaker: Gary McGraw is the Vice President of Corporate Technology at Cigital (formerly Reliable Software Technologies) where he pursues research in software security while leading the Software Security Group.

Peter Stephenson, Investigating Computer Security Incidents Nov 08, 2000

The studies all say that 70% to 80% of information security incidents involve "insiders". However, today, it is becoming increasingly difficult to pinpoint exactly what we mean by an insider. Complicating the issue, law enforcement is increasingly overloaded and the FBI has gone on record as saying that the victims of such incidents should begin their own investigation. The good news is that the victim will likely be in a position to respond much more rapidly than will law enforcement. The bad news is if the victim does not respond correctly, evidence may be irretrievably lost or damaged limiting or eliminating the effective response by law enforcement at a later point. Where law enforcement is not to be involved, such errors can have a devastating effect on civil litigation. This seminar will explore the resources available for investigating a computer security incident, discuss the investigative process, explore the underlying legal issues and specific laws and introduce some forensic techniques that a victim may use to preserve evidence correctly. About the speaker: Peter Stephenson is the director of technology for the global security practice of Netigy Corporation. He has been in technology-related positions for over 35 years, and has operated his own consulting practice for 15 years.

Wenke Lee, Developing Data Mining Techniques for Intrusion Detection: A Progress Report Oct 11, 2000

Intrusion detection (ID) is an important component of infrastructure protection mechanisms. Intrusion detection systems (IDSs) need to be accurate, adaptive, extensible, and cost-effective. These requirements are very challenging because of the complexities of today's network environments and the lack of IDS development tools. Our research aims to systematically improve the development process of IDSs. In the first half of the talk, I will describe our data mining framework for constructing ID models. This framework mines activity patterns from system audit data and extracts predictive features from the patterns. It then applies machine learning algorithms to the audit records, which are processed according to the feature definitions, to generate intrusion detection rules. This framework is a "toolkit" (rather than a "replacement") for the IDS developers. I will discuss the design and implementation issues in utilizing expert domain knowledge in our framework. In the second half of the talk, I will give an overview of our current research efforts, which include: cost-sensitive analysis and modeling techniques for intrusion detection; information-theoretic approaches for anomaly detection; and correlation analysis techniques for understanding attack scenarios and early detection of intrusions.

John Richardson, Evolving the Internet Sep 20, 2000

What's wrong with today's Internet? If TCP/IP has won, what's left to be done? In truth, we've only just begun ... to understand the how the Internet is evolving, the impact of our staggering demand for information, and how a whole set revolutionary technologies will change the Internet's foundation. This talk skims the waves - it highlights some of the key changes on the horizon and explains why they will be important. Some key trends we'll touch on include: overlay networks like voice-over-IP, media overlays, and security overlays; quality-of-service and how to manage it; peer-to-peer networking - what's driving it and how it may change the Internet completely; and security protocols - how they're being used and why they're not everywhere. This will be a technical talk, focused on how things work and why these trends are interesting. Don't expect to walk away with a new set of tools, but do expect to come away with a better understanding of how things work and a some new ideas about some emerging technologies that may just change everything. About the speaker: Mr. Richardson is the Director of the Trusted Networking Architecture group at Intel Corporation. His organization explores and develops advanced technology for security and network services for the Internet.

Eugene Spafford, The Challenge of Secure Software Sep 13, 2000

Despite decades of advances in computer science and software engineering, our computing systems seem to be less and less trustworthy. Each week seems to bring new stories of computer viruses, invasions of privacy, serious bugs in common software platforms, and network intrusions. The trend seems to be getting worse instead of better. Why is that? And is there hope for safer systems for day-to-day use in e-commerce and government? In this talk, we will examine some of the factors that have led to this distressing state of events. Included will be a discussion of some rules for designing secure software, and an examination of why the current Internet marketplace encourages those rules to be ignored. The clear solution is not one of technology -- but of consumer action. Audience feedback is encouraged. About the speaker: Dr. Spafford received his B.A. degree with a double major in Mathematics and Computer Sciences from the State University College at Brockport (1979, NY). Upon graduation, he was honored with a SUNY College President\'s Citation. He then attended the School of Information and Computer Sciences (now the College of Computing) at Georgia Institute of Technology, holding both a Georgia Tech President\'s Fellowship and a National Science Foundation Graduate Fellowship. He received his M.S. in 1981, and the Ph.D. in 1986 for his design and implementation of the original Clouds reliable, distributed operating system kernel, and for his contributions as one of the original members of the Clouds design team. Next, Dr. Spafford spent a year and a half as a research scientist with the Software Engineering Center at Georgia Tech. His duties there included serving as a principal software engineer with the Mothra software testing project.

Jens Palsberg, Static Checking of Interrupt-Driven Software Sep 06, 2000

Resource-constrained devices are becoming ubiquitous. Examples include cell phones, palm pilots, and digital thermostats. It can be difficult to fit required functionality into such a device without sacrificing the simplicity and clarity of the software. Increasingly complex embedded systems require extensive brute-force testing, making development and maintenance costly. This is particularly true for system components that are written in assembly language. Static checking has the potential of alleviating these problems, but until now there has been little tool support for programming at the assembly level. In this paper we present the design and implementation of a static checker for interrupt-driven Z86-based software with hard real-time requirements. For six commercial microcontrollers, our checker has produced upper bounds on interrupt latencies and stack sizes, as well as verified fundamental safety and liveness properties. Our approach is based on a known algorithm for model checking of pushdown systems, and produces a control-flow graph annotated with information about time, space, safety, and liveness. Each benchmark is approximately 1000 lines of code, and the checking is done in a few seconds on a standard PC. Our tool is one of the first to give an efficient and useful static analysis of assembly code. It enables increased confidence in correctness, significantly reduced testing requirements, and support for maintenance throughout the system life-cycle. Joint work with Dennis Brylow and Niels Damgaard. About the speaker: Jens Palsberg received a Ph.D. in Computer Science from University of Aarhus, Denmark in 1992. In 1992-1996 he was a visiting scientist at various institutions, including MIT. In 1996 he joined the faculty at Purdue University where he is an Associate Professor of Computer Science.

Dr. Palsberg\'s research has been supported by NSF, DARPA, IBM, and British Telecom. He is a member of the editorial board of IEEE Transactions on Software Engineering.

Pascal Meunier, The IRDB Project: An Incident Response Database For Gathering Cost And Incidence Information On Types of Security Events Aug 30, 2000

Information about the incidence of security breaches is difficult to obtain. Emergency situations are not favorable to the maintenance of records, the security breaches are embarrassing and possibly damaging, and disclosing information about the incidents may reveal some sensitive information. Moreover, the nature of the incident and its cause are not always fully known. Because of this, the frequency and cost is difficult to assess by type of incident. The IRDB project attempts to provide a framework to record incident information and duration. Besides email and cost recording, it provides a dynamic classification of incidents. In the IRDB, incidents have a risk type and an attack type. The risk type expresses the consequences of the attack (e.g., root access). The attack type identifies kinds of attacks (e.g., SANS top ten). Each type is itself classified by properties. With this system, we hope that 1) organizations using the same type classification can directly share data; 2) organizations not using the same type classification can translate data based on the properties of the types; 3) statistical data from many different organizations can be assembled to present a coherent picture of incident costs and frequencies on a national scale. By making the type classification dynamic, it is hoped that the severity of future, currently unknown types of attacks can be rapidly assessed. About the speaker: Pascal began managing the Vulnerabilities Database and Incident Response Database projects as a graduate student. He joined CERIAS in a research scientist capacity in May of this year. Pascal graduated from Purdue with a M.Sc. in computer sciences, which he added to his previous Ph.D. in Biophysics from the University of Qu

John Steven Reel, The Future of Information Security Technologies Aug 23, 2000

Information security, and the technologies that provide such security, are a very hot topic throughout the information technology and business communities today. This presentation opens with a consideration of the current network environment. It answers the questions "where are these technologies?" and "where are the gaps in the technologies that are being addressed?" especially as they impact security. Next, the presentation considers the field of network security technologies. It addresses the good, the bad and the undecided aspects of the field today. After setting the stage with this background information, the presentation identifies the most important trends that will impact the network security industry in the coming few years: the federal government finally cares, the vanishing network perimeter, and the opportunity to achieve ubiquitous encryption. Toward the end of the presentation, Dr. Reel presents two "killer" security-related applications. Finally, the presentation closes with a discussion of the major needs in the information security field. About the speaker: Dr. Reel has BS and Ph.D. degrees in Computer Science. He spent over 9 years with the National Security Agency developing network-based software for deployment around the world. In 1995, he joined Trident Data Systems (now Veridian Corporation) in their San Antonio operation.

Rick Davis, The Holy Grail of E-Business Risk Management: Creating and Sustaining the Insurable Standard for E-Business Security and Assurance Apr 28, 2000

In order for e-commerce and e-business to grow at the fullest extent possible, higher levels of trust and accountability need to become established. The corporate buyers who rely on reliable structures need to hold those who build and support commercial network initiatives (call them "infrastructure and service providers") responsible for things that go wrong. Downtime, outages, viruses, data integrity, data confidentiality and hacker damage are some of the losses that providers need to prevent and absorb in a proactive manner. Today it is the ecommerce buyer / user who get stuck holding the bag. In the near future it will be the provider who will be held responsible. There is a world of difference between information security and e-business risk management. Traditional info security just looks at the technical / network controls that ecommerce relies on. Ebusiness risk management takes a multi-disciplinary approach that instills controls throughout the enterprise, not just in the technology. This multi-disciplinary approach addresses the legal, operational, financial and technical controls that must be present in all ebusiness environments. Addressing an aspect of the financial controls, insurance is a necessary element in all ebusiness risk management strategies. If a loss occurs (which it always will - there's no such thing as a 100% perfect system), a specialized insurance policy is the financial mechanism that will allow the ecommerce provider to absorb the loss and pay for the damages. About the speaker: Rick is a recognized pioneer in the e-business risk management industry. Rick is widely acknowledged for creating the world\'s first e-risk insurability standard for underwriting e-business exposures. Since graduating from Stanford University in 1991, Rick has developed asset protection strategies for mission-critical e-business environments. He has been an executive manager in the Electronic Commerce / Internet / Information Security industry his entire career and has specialized in creating multi-disciplinary e-business risk management solutions (combining information security, traditional risk management and insurance) for nearly four years. Aon Corporation (world\'s 2nd largest risk management and insurance broker) recently hired Rick as Vice President of Sherwood Insurance, an Aon-owned wholesale broker. Under the Sherwood banner, Rick is responsible for defining the Aon corporate e-business risk management initiative and creating a consulting practice that will be delivered to Aon\'s Global 2000 customers.

Michael G. Fleming & Victor Maconachy, Information Assurance Challenges for the 21st Century Apr 21, 2000

In today's increasingly dependent and interdependent global information society, information assurance for systems is gaining tremendous importance. Individuals, governments, and societies are insisting on secure and safe communications environments. The solution to providing those assurances lies in the formation of partnerships between and among business, academia and government. Mr. Fleming will present an overview of a model for such partnerships, to include critical elements for the success of those joint ventures. Dr. Maconachy will briefly discuss the cognitive and social implications related to moving towards a global security-based enteprise. About the speaker: Michael G. Fleming is Chief of the Information Assurance Solutions Group and has also served as Chief of the INFOSEC Customer Service and Engineering Group, Deputy Chief of Network Security Group, Chief of Network Security Systems Engineering Office, Chief of Network Security Products Office, as well as served in a variety of technical and program management positions in Communications Security and Signals Intelligence. He received his BS in Electrical Engineering from Purdue University, his MS in Administrative Science from Johns Hopkins University, and attended and graduated from the National War College. Victor Maconachy currently serves as the program manager of the National INFOSEC Education and Training Program (NIETP) within the National Security Agency. He is implementing a multidimensional, interagency program which provides direct support and guidance to the services, major DoD components, Federal agencies and the greater national Information Infrastructure. This program fosters the development and implementation of INFOSEC training programs, as well as graduate and undergraduate education curricula. In this capacity he serves on several national level government working groups, as well as in an advisory capacity to several universities. In this position, Dr. Maconachy is the principal architect for several national INFOSEC training standards in the classified community. During April, 1999 Dr. Maconachy was appointed Co-chair of the Critical Information Coordination Committee for Personnel and Training. The Committee is implementing Presidential Decision Directive 63.

Terran Lane, Machine Learning Techniques for Anomaly Detection in Computer Security Apr 07, 2000

With the recent phenomenal growth of the availability and connectivity of computing resources and the advent of e-commerce, more valuable and private data is being stored online than ever before. But with greater value and availability comes greater threat. In this talk we examine the information security problem of anomaly detection --- recognizing the occurrence of ``out of the ordinary'' events which may prove to be hazardous. We evaluate this problem as a machine learning task and describe the application of two machine learning techniques: instance-based learning (IBL) and hidden Markov models (HMMs). This work focuses on anomaly detection at the user level (as opposed to the network or system call level), which introduces a number of interesting and complex issues from a machine learning standpoint. In particular, we explore privacy, resource constraints, non-stationarity (a.k.a. concept drift), and performance issues and give empirical analyses based on real user data. We close with some thoughts on extensions to this work and on other areas of application. About the speaker: graduated from Ballard High School (Louisville, KY) in 1990 and entered the department of Electrical and Computer Engineering (then the department of Electrical Engineering) at Purdue University (West Lafayette, IN) in the fall of that year. I have been here ever since, attaining my bachelor\'s (BSCEE == Bachelor of Science in Computer and Electrical Engineering) in May of 1994. I immediately plunged into the PhD program, and am currently working toward that degree under the direction of Professor Carla Brodley. Some notes on my Research are available.

Padgett Peterson, Implications of Mobile Code on Microsoft Platforms Mar 31, 2000

With the advent of mobile code (excutable programs that are carried on web pages and inside E-Mail) in everyday use, the capability to include malicious software without the recipient's knowlege has been implicit. From the first crude examples ("Concept", 1995) through the "Russian New Year" exploits (1997-98), to the current surprises (Bubbleboy, 1999) there has been a continual advance in sophistication. Despite attempts by the manufacturer to provide mitigation, these patches are little known or applied and often apply only to the latest versions and not the bulk of the installed base. We shall examine the built-in capabilities that make this possible, the probable rationale behind such decisions, and the implication for future events. About the speaker: Mr. Peterson is currently the principal corporate information security architect for Lockheed-Martin Corporation. With over thirty years experience in computers, cryptography, and malicious software, he has written BIOS-level antivirus freeware (\"DIskSecure\", 1990) and macro-based WORD macro protection (\"Macrolist\", 1996). A frequent speaker at security conferences he is an internationally recognized expert in the field. He also collects Pontiacs

Judy Hochberg, Automatic identification of classified documents Feb 25, 2000

How can one automatically identify classified documents? This is a vital question for the Department of Energy (DOE), which is reviewing millions of classified documents for possible declassification, and for Los Alamos National Laboratory (LANL), which is checking its unclassified computing storage systems for the presence of classified documents. The DOE, having already developed an expert rule system for automatic document classification, provided LANL with a small set of documents with which to explore a statistical classifier as an alternative. We represented documents as vectors of character trigram frequencies, used a chi-square statistic to select the optimal trigrams, and trained a linear classifier to distinguish classified and unclassified documents. Results ranged from 60% to 87% accuracy, depending on the training set size and other variables. In contrast, the LANL effort started "from scratch" and needed to be moved rapidly into large-scale production. We implemented an expert system tailored to the classified documents of most concern to LANL. The talk will discuss the practical issues that arose in canvassing large amounts of files in a variety of formats, and the security issues involved in the sampling, analysis, and notification processes. About the speaker: Judy Hochberg is a staff scientist at Los Alamos National Laboratory. She received a B.A. in linguistics from Harvard and a Ph.D. in linguistics from Stanford. Before joining the Laboratory in 1989, she was a post-doctoral researcher at the University of Chicago, then a visiting Assistant Professor at Northwestern University. She has published in journals including Computers and Security, IEEE Transactions in Pattern Analysis and Machine Intelligence, and Language. She has been an R&D 100 award winner and a national finalist in the Johns Hopkins National Search for Computing to Assist Persons with Disabilities. Judy is interested in all manifestations of human language, including document analysis -- text and images -- and speech.

Clay Shields, Tracing Denial-of-Service Attacks; or why we may never know who attacked Yahoo et. al. Feb 18, 2000

The recent spate of attacks against Yahoo and other sites with large on-line presences brought denial-of-service attacks into the public consciousness. The methods used in these attacks make it very difficult, if not impossible, to locate the source of the attacks. The problem lies not only in finding the particular computers used to launch the attacks, but also in finding the individuals controlling those computers. I will discuss the attacks that occurred, why it is so difficult to track the intruders, research work that attempt to make it possible do so, and open research problems in the area. CERIAS has on-going work related to the problem of tracking intruders across the Internet, and I expect this to be an evolving and interesting area of research in the future. About the speaker: Clay was born in Washington, D.C, and spent much of his childhood living overseas as required by the career of his stepfather, who was a covert agent for the CIA. Clay got an undergraduate degree in electrical engineering from the University of Virginia, and after a year as a computer programmer on Capitol Hill, joined the U.S. Army. As an infantry officer with the 101st Airborne Division, Clay served overseas with the peace-keeping force in the Sinai Peninsula, earning a commendation for liaison work with the Egyptian and Israeli military. Because sitting in a muddy foxhole with a rifle was not intellectually challenging enough, Clay left the Army to return to graduate school. He attended the University of California at Santa Cruz, and for his dissertation he studied computer networking, particularly multicast routing and network security issues. With the ink not yet dry on his PhD, Clay took a job as an assistant professor in computer science at Purdue University, not so much for easy access to corn, but to be associated with CERIAS and to continue his research into network security. Clay is particularly interested in finding ways to exploit existing protocols, in designing secure protocols and in finding ways to keep careful track of what is happening in a network while maintaining user privacy and anonymity.

Gerald Thomas, Commercial High-Resolution Satellite Imagery Polic Feb 11, 2000

In October of 1999, Denver based Space Imaging launched the world's first very-high resolution commercial satellite, IKONOS 2, into polar orbit around the earth. For the first time in history, sub-1 meter near real time digital imagery is now available for virtually the entire globe to anyone with a credit card and access to the internet. This talk will explore: (1) the policy history around the US government's decision to let this technology "go commercial," (2) the status of current US remote sensing policy and some remaining policy issues that still need to be addressed, and (3) the potential implications of this information revolution for national security, law enforcement, privacy, and several other issues. About the speaker: Dr. Gerald Thomas is an assistant professor of political science at Purdue University where he teaches and does research in the area of public policy. His current research interests focus at the intersection of environmental policy and science and technology policy. He has published on the topics of environmental security, US national security policy, and US space policy.

Victor Raskin, NLP for IAS: Overview and Implementations Feb 04, 2000

This paper explores a promising interface between natural language processing (NLP) and information assurance and security (IAS). More specifically, it is devoted to possible applications of the accumulated considerable resources in NLP to IAS. The paper is of a mixed theoretical and empirical nature. Of the four possible venues of applications, (i) memorizing randomly generated passwords with the help of automatically generated funny jingles, (ii) natural language watermarking, (iii) using the available machine translation (MT) systems for (additional) encryption of text messages, and (iv) downgrading, or sanitizing, classified information in networks, two venues, (i) and (iv), have been at least partially implemented, and the remaining two, (ii) and (iii), are being implemented to the proof-of-concept level. We feel that it is important, however, even at this early stage, to review for the information security community what NLP can do for it and to invite feedback and further efforts and ideas in this direction. About the speaker: Victor Raskin founded the Interdepartmental Program in Linguistics at Purdue and chaired it in 1979-99. He also founded the Natural Language Processing (NLP) Laboratory at Purdue in 1986 and has coordinated it ever since. He is the author of 16 books and close to 200 articles on natural language processing (computational linguistics), linguistic and semantic theory, philosophy of language and science, and various applications of linguistics and computational linguistics to adjacent areas, including to information security. Together with Sergei Nirenburg, Director, Computing Research Laboratory, New Mexico State University, he has developed a ground-breaking ontological semantic approach to NLP that, for the first time, provides near-comprehensive semantic capabilities to NLP systems and thus ensures their accuracy. He has been a PI, co-PI, and PI-level consultant for a large number of NLP research grants since 1966 in his native Russia, Israel, and this country, most recently on the interface of NLP and information security. Professor Raskin has served on the CERIAS Internal Advisory Board since its inception. The presentation is based on joint research with Mikhail J. Atallah, Craig J. McDonough, and Sergei Nirenburg

Gene Kim, Open Source Issues and Opportunities for Tripwire Jan 21, 2000

Tripwire has a long history of openly available source, having been created at Purdue University in 1992 as a publicly available security tool. It has been created into an industrial strength tool, and has been successful in protecting critical enterprise processes in business and government. One of the decisions we made was to use a conventional shrink-wrapped software model -- in other words, source code was no longer readily available to the public. Without question, this has been a smooth and successful transition. Tripwire v2.0 provided a variety of additional compelling features so that customers have embraced the new product. However, there were some things that happened along the way that didn't quite go as planned. And some things were just were downright surprising. This presentation will address some of the consequences of having a closed source product, and describe some issues in considerable detail. Then, possible "open source" opportunities will be presented, with all sorts of benefits discussed, evaluated, and some discarded. Some perceived dangers are mulled over, and also evaluated. Audience participation will be encouraged. About the speaker: Gene Kim is the chief technology officer and co-founder of Tripwire(tm), Inc. In 1992 at Purdue University, he co-authored the Tripwire file integrity assessment software with Dr. Gene Spafford. Kim is widely published on computer security, operating systems and networking in Usenet, ACM and IEEE publications and is a frequent speaker at industry conferences. He holds an M.S. in computer science from University of Arizona and a B.S. in computer sciences from Purdue University.

Wenliang Du & Mahesh Tripunitara, Security Relevancy Analysis on the Registry of Windows NT 4.0 (for Wenliang Du) Nov 19, 1999

Many security breaches are caused by inappropriate inputs crafted by people with malicious intents. To enhance the system security, we need either to ensure that inappropriate inputs are filtered out by the program, or to ensure that only trusted people can access those inputs. In the second approach, we sure do not want to put such constraint on every input, instead, we only want to restrict the access to the security relevant inputs. The goal of this paper is to investigate how to identify which inputs are relevant to system's security. We have formulated the problem as an security relevancy problem, and deploy static analysis technique to identify security relevant inputs. Our approach are based on dependency analysis technique, it identifies if the behavior of any security critical action depends on certain input. If such a dependency relationship exists, we say that the input is security relevant, otherwise, we say the input is security non-relevant. We have applied this technique to a security analysis project initiated by Microsoft Windows NT security group. The project is intended to identify security relevant registry keys (a special kind of input) in Windows NT operating system. The results produced from this approach is proved to be useful to enhance Windows NT security. We will report our experience and results from this project in the paper. Thwarting Denial of Service Attacks against Communication Protocols with Backward Compatible Changes: A Case Study(for Mahesh Tripunitara) We will discuss a novel approach to building safeguards against denial of service attacks against communication protocols. Our approach involves changes to the relevant communication protocol subject to the following constraint: the protocol that results from the change must be backward compatible with the unchanged protocol. That is, an entity that employs the changed protocol must be able to communicate with an entity that employs the unchanged version. We will look at a specific problem in this context. The problem involves a class of denial of service attacks against IP. The class is called ARP (Address Resolution Protocol) cache poisoning and involves an attacker introducing a spurious IP to Ethernet mapping in a victim's ARP cache. We will discuss the solution and some implementation aspects of it. Apart from being backward compatible, our solution has two favourable properties: it is implemented as middleware, and is asynchronous About the speaker: Mahesh Tripunitara is a PhD student of computer science at Purdue, a member of CERIAS and an advisee of Prof. Gene Spafford. At dawn, he commutes 85 miles to campus, during the day, he dreams of graduation, and during the night he snoozes at his desk. He performed part of this work during a 9-month exile at AT&T Labs, 2500 miles away. Portions of this work will be presented at the upcoming Annual Computer Security Applications Conference (ACSAC'99). Wenliang (Kevin) Du is a PhD student of computer science at Purdue, a member of CERIAS and an advisee of Prof. Gene Spafford. His most recent research involves security testing and security analysis of software, with the focus on COTS software. He got his Bachelor's degree from the University of Science and Technology of China. He got his first industry work experience from Microsoft, where part of this work was performed. Portions of this work will be presented at the upcoming Annual Computer Security Applications Conference (ACSAC'99).

Donn Parker, Information Security, a Folk Art in Need of an Upgrade Nov 12, 1999

Information security is an inarticulate, incoherent, incomplete, incorrect folk art attempting to preserve confidentiality, integrity, and availability (CIA) of information from destruction, disclosure, use, and modification (DDUM). This CIA/DDUM framework is the equivalent of alchemy in the middle ages when the elements consisted of fire, water, earth, and air. We must have security based on a coherent and complete framework model for stopping irrational cybercriminals. We must replace security risk reduction, an unmeasurable negative goal, with achieving standards of due care consistent with the new view of security as an enabling function. About the speaker: Donn B. Parker (1929-2021), an emeritus senior consultant at SRI Consulting, has spent 30 of his 47 years in the computer field doing research on computer crime, and consulting, writing, and lecturing on information security. He is the founder at SRI of I-4 serving more than 75 of the largest multinational corporations in their security for 14 years. He has written six books. His newest book, "Fighting Computer Crime: A New Framework for Protecting Information," (Wiley, 1998) is an international best seller. He received the ISSA Individual Achievement Award, the United States National Computer Systems Security Award, the Aerospace Computer Security Distinguished Lecturer Award, and the MIS Infosecurity Magazine Lifetime Achievement Award. In September 1999, The Information Security Magazine profiled him as a pioneer in information security.

Edward J. Delp, Image and Video Watermarking: An Overview Sep 10, 1999

In the past several years there has been an explosive growth in digital imaging technology and applications. Digital images and video are now widely distributed on the Internet and via CD-ROM. One problem with a digital image is that an unlimited number of copies of an "original" can be easily distributed and/or forged. This presents problems if the image is copyrighted. The protection and enforcement of intellectual property rights has become an important issue in the "digital world." Many approaches are available for protecting digital images and video; traditional methods include encryption, authentication and time stamping. In this talk we describe algorithms for image authentication and forgery prevention known as digital watermarking. A digital watermark is a signal that is embedded in a digital image or video sequence that allows one to establish ownership, identify a buyer or provide some additional information about the digital content. In this talk we will review the current state of watermarking and describe some of the open research problems. About the speaker: Edward J. Delp was born in Cincinnati, Ohio. He received the B.S.E.E.

Gene Spafford, Twelve Challenges in Information Security Research Sep 03, 1999

Current research in information security at many labs are largely focused on traditional themes: firewalls, intrusion detection, cryptography, and computer viruses. However, there are other challenges that need to be addressed to provide a basis for protecting our information infrastructure. About the speaker: Spaf is the Director of CERIAS and is a noted researcher and iconoclast. A more comprehensive vita is available online.

Clay Shields, KHIP - A Scalable Protocol for Secure Multicast Routing Aug 27, 1999

Multicast routing is a service that provides for efficient many-to-many communication in a network. Traditionally, secure multicast protocols have used existing multicast routing services and relied on cryptographic protection of the messages sent to provide security. Much previous work in the area has been on methods of establishing a shared key between members subscribing to the multicast group. Some problems with this approach are that any network member can receive the encrypted traffic, and that the multicast routing protocol itself is subject to attacks which allow for effective denial-of-service attacks against the group members. I present Keyed-HIP (KHIP), a protocol for secure, hierarchical, multicast routing that changes the multicast model to prevent non-group members from receiving the secure traffic, and limits the effectiveness of denial of service attacks against the multicast group. KHIP also provides an efficient mechanism for distributing data encryption keys to all members of the group. While the type of security provided by KHIP is not necessary in all cases, for some applications the traditional model of multicast security may be lacking. About the speaker: Clay was born in Washington, D.C, and spent much of his childhood living overseas as required by the career of his stepfather, who was a covert agent for the CIA. Clay got an undergraduate degree in electrical engineering from the University of Virginia, and after a year as a computer programmer on Capitol Hill, joined the U.S. Army. As an infantry officer with the 101st Airborne Division, Clay served overseas with the peace-keeping force in the Sinai Peninsula, earning a commendation for liaison work with the Egyptian and Israeli military. Because sitting in a muddy foxhole with a rifle was not intellectually challenging enough, Clay left the Army to return to graduate school. He attended the University of California at Santa Cruz, and for his dissertation he studied computer networking, particularly multicast routing and network security issues. With the ink not yet dry on his PhD, Clay took a job as an assistant professor in computer science at Purdue University, not so much for easy access to corn, but to be associated with CERIAS and to continue his research into network security. Clay is particularly interested in finding ways to exploit existing protocols, in designing secure protocols and in finding ways to keep careful track of what is happening in a network while maintaining user privacy and anonymity.
