In this paper, by incorporating knowledge of the physical system under control, we proposed the new method to detect computer attacks that change the behavior of the targeted industrial control system. By using knowledge of the physical system we are able to focus on the final objective of the attack, and not on the particular mechanisms of how vulnerabilities are exploited, and how the attack is hidden. We also analyze the safety of our solution by exploring the effects of stealthy attacks, and by hopping that automatic attack-response mechanisms will not drive the system to an unsafe state. |
