Cyber-Physical Security of a Chemical Plant
the increasing number of cyber-attacks on industriesdemands immediate attention for providing more securemechanisms to safeguard industries and minimize risks. Cyberphysical systems (CPS) being used in industries such as oil and gas, chemical process plants and the like are termed Industrial Control Systems (ICS). Control system security is aimed at preventing intentional or unintentional interference with the proper operation of industrial automation and control systems (ICS). This paper proposes a process-Aware approach with the use of some invariant equations based on the physical and chemical properties of the process and a Multiple Security Domain Nondeducibility (MSDND) framework to detect when a sensor signal is being maliciously manipulated. We have taken benzene production plant as case study to illustrate our approach and its effectiveness in determining the state of the system.
