CERIAS Weekly Security Seminar - Purdue University

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. Mr. Waymire began his career as a software developer at Honeywell Defense Avionic Systems in Albuquerque New Mexico, where he developed the requirements, design, implementation, and testing of software for a variety of platforms that included the F-15, C-27J, KC-10, C-130, and the C5 aircraft. He then went on to Sandia National Laboratories in Albuquerque New Mexico where he has had an opportunity to work on a wide range of projects including algorithms in combinatorial optimization, software development for mod-sim force-on-force interactions and cognition/AI development, satellite software for operational systems in orbit, cyber vulnerability assessments for various US government agencies, and cyber physical assessments for numerous foreign partners that included physical and cyber upgrades at nuclear power plants and research reactors worldwide. Russel currently uses his experience and insights to lead a team researching innovative ways to protect critical infrastructure, space systems, and other high-consequence operational technologies.
