False Logic Attacks on SCADA Control System

A cyber security incident in SCADA systems can cause the disruption of physical process, and may result in significant economic loss, environmental disasters or even human casualties. To exploit the feature of the physical process and find the potential attacks, this paper presents and analyzes a new class of cyber-physical attacks, named false logic attacks, against the logic of control process in SCADA systems. In addition, it proposes a model for false logic attacks, which is useful for analyzing how attacks can affect the physical system. An experiment is performed to illustrate the concepts, and the effect of false logic attacks are also discussed.
