ADROC: AN EMULATION EXPERIMENTATION PLATFORM FOR ADVANCING RESILIENCE OF CONTROL SYSTEMS.

Industrial control systems have increasingly been targeted by cyberattacks, so it is crucial that system owners have tools to understand their systems’ resilience to them. Many existing tools, however, are qualitative, generic, or driven by subject matter expertise, making thorough cyber resilience analysis a challenge. The ADROC project, under the Resilient Energy Systems Mission Campaign, developed a two-phase system modeling platform for data-driven resilience analysis and threat prioritization in collaboration with Sandia Alliance partner University of Illinois at Urbana-Champaign. Math models efficiently

filter out threat scenarios of low concern, and emulation models enable more detailed analysis for threats of high concern. Data extracted from the experiments are used to calculate cyber resilience metrics and prioritize threats. ADROC can be used to analyze proposed system designs, cyber threats, and more. The work of ADROC, published at the Sat-CPS ‘22: Proceedings of the 2022 ACM Workshop on Secure and Trustworthy Cyber-Physical Systems, will be extended through future efforts to develop capabilities so critical system owners can understand and improve the cyber resilience of their systems.
