Our new publication “Modeling and Simulation Approaches for Cybersecurity Impact Analysis: State-of-the-Art” is now published online. In this paper, we survey the existing literature to aggregate the diverse modeling and simulation-based approaches that have been used to define and/or characterize the impact of attacks on cyber-physical and industrial control systems. The resulting analysis provides insight into the varying definitions of impact and domains of application, providing recommendations to guide future impact analysis studies. It was presented at the 2021 Annual Modeling and Simulation Conference (ANNSIM) in July 2021. See Publications for more details!
