Designing Security Into Software-Reliant Systems Jun 25, 2015

Show notes

Software is a growing component of modern business- and mission-critical systems. As organizations become more dependent on software, security-related risks to their organizational missions are also increasing. Traditional security-engineering approaches rely on addressing security risks during the operation and maintenance of software-reliant systems. However, the costs required to control security risks increase significantly when organizations wait until systems are deployed to address those risks. It is more cost effective to address software security risks as early in the lifecycle as possible. As a result, researchers from the CERT Division of the Software Engineering Institute (SEI) have started investigating early lifecycle security risk analysis (i.e., during requirements, architecture, and design). In this podcast, CERT researcher Christopher Alberts introduces the Security Engineering Risk Analysis (SERA) Framework, a systematic approach for analyzing complex security risks in software-reliant systems and systems of systems early in the lifecycle. The framework integrates system and software engineering with operational security by requiring engineers to analyze operational security risks as software-reliant systems are acquired and developed. Initial research activities have focused on specifying security requirements for these systems. Listen on Apple Podcasts.

Agile Methods in Air Force Sustainment Jun 11, 2015

Show notes

For several years, the Software Engineering Institute has researched the viability of Agile software development methods within Department of Defense programs and barriers to the adoption of those methods. In this podcast, SEI researcher Eileen Wrubel discusses how software sustainers leverage Agile methods and avoid barriers to using Agile methods. Listen on Apple Podcasts.

Defect Prioritization With the Risk Priority Number May 28, 2015

Show notes

Most software systems have some "defects" that are identified by users. Some of these are truly defects in that the requirements were not properly implemented; some are caused by changes made to other systems; still others are requests for enhancement – improvements that would improve the users' experience. These "defects" are generally stored in a database and are worked off in a series of incrementally delivered updates. For most systems, it is not financially feasible to fix all of the concerns in the near term, and indeed some issues may never be addressed. The government program office has an obligation to choose wisely among a set of competing defects to be implemented, especially in a financially constrained environment. In this podcast, Will Hayes and Julie Cohen discuss a generalized technique that could be used with any type of system to assist the program office in addressing and resolving the conflicting views and creating a better value system for defining releases.

SEI-HCII Collaboration Explores Context-Aware Computing for Soldiers May 14, 2015

Show notes

As the number of sensors on smart phones continues to grow, these devices can automatically track data from the user's environment, including geolocation, time of day, movement, and other sensor data. Making sense of this data in an ethical manner that respects the privacy of smartphone users is just one of the many challenges faced by researchers. In this podcast, Dr. Anind Dey, director of the Human Computer Interaction Institute (HCII) at CMU, and Dr. Jeff Boleng, principal researcher at the SEI, introduce context-aware computing and discuss a collaboration to help dismounted soldiers using context derived from sensors on them and their mobile devices, to ensure that they have the information and sensor support they need to optimize their mission performance.

An Introduction to Context-Aware Computing Apr 23, 2015

Show notes

As the number of sensors on smart phones continues to grow, these devices can automatically track data from the user's environment, including geolocation, time of day, movement, and other sensor data. Making sense of this data in an ethical manner that respects the privacy of smartphone users is just one of the many challenges faced by researchers. In this podcast, the first in a two-part series, Dr. Anind Dey and Dr. Jeff Boleng introduce context-aware computing and explore other issues related to sensor-fueled data in the internet of things.

Data Driven Software Assurance Apr 09, 2015

Show notes

Software vulnerabilities are defects or weaknesses in a software system that, if exploited, can lead to compromise of the control of a system or the information it contains. The problem of vulnerabilities in fielded software is pervasive and serious. In 2012, SEI researchers began investigating vulnerabilities reported to the SEI's CERT Division and determined that a large number of significant and pernicious software vulnerabilities likely had their origins early in the software development lifecycle in the requirements and design phases.In this podcast, SEI researchers Mike Konrad and Art Mansion discuss a project that was launched to investigate design-related vulnerabilities and quantify their effects.

Applying Agile in the DoD: Twelfth Principle Mar 26, 2015

Show notes

In this episode, the 12th and final podcast in a series by Suzanne Miller and Mary Ann Lapham exploring the application of Agile principles in the Department of Defense, the two researchers discuss the application of the 12th principle: at regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly. Listen on Apple Podcasts.

Supply Chain Risk Management: Managing Third Party and External Dependency Risk Mar 26, 2015

Show notes

One caveat of outsourcing is that you can outsource business functions, but you cannot outsource the risk and responsibility to a third party. These must be borne by the organization that asks the population to trust they will do the right thing with their data.In this podcast, Matt Butkovic, the Technical Manager of CERT's Cybersecurity Assurance Team, and John Haller, a member of Matt's team, discuss approaches for more effectively managing supply chain risks, focusing on risks arising from "external entities that provide, sustain, or operate Information and Communications Technology (ICT) to support your organization." This is sometimes referred to as third party or external dependency risk. Listen on Apple Podcasts.

Introduction to the Mission Thread Workshop Mar 12, 2015

Show notes

In Department of Defense programs, a system of systems (SoS) is integrated to accomplish a number of missions that involve cooperation among individual systems. Understanding the activities conducted within each system and how they interoperate to accomplish the missions of the SoS is of vital importance. A mission thread is a sequence of end-to-end activities and events, given as a series of steps, that accomplish the execution of one or more capabilities that the SoS supports. However, listing the steps and describing them do not reveal all the important concerns associated with cooperation among the systems to accomplish the mission; understanding the architectural and engineering considerations associated with each mission thread is also essential. In this podcast, Michael Gagliardi introduces the Mission Thread Workshop (MTW), a facilitated, stakeholder-centric workshop whose purpose is to elicit and refine end-to-end quality attribute, capability, and engineering considerations for SoS mission threads. Listen on Apple Podcasts.

Applying Agile in the DoD: Eleventh Principle Feb 26, 2015

Show notes

In this episode, the 11th in a series by Suzanne Miller and Mary Ann Lapham exploring the application of Agile principles in the Department of Defense, the two researchers discuss the application of the 11th principle: the best architectures, requirements, and designs emerge from self-organizing teams.
