  • System and method for modeling and analyzing the impact of cyber-security events on cyber-physical systems
    Patent number: 10262143
    Abstract: A system and method for systematically undertaking model-based security analysis of a cyber physical system (CPS) is provided. In one example, a cyber model simulation and a control system simulation are mapped using various methods to determine which portions of the cyber-model simulation and the control system simulation are correlated with one another. Using the determined correlation, when a cyber-attack is generated on the cyber model simulation, a corresponding attack hook can be generated for the control system model. The attack hook is configured to be integrated into the control system model so as to mimic the effect on the control system that a cyber-attack can engender. Once one or more attack hooks are generated, the user can place the hooks into the control system simulation schemas and run a series of simulations to determine the effects of a cyber event on the control system in a CPS.
