Process-Aware Model based IDSs for Industrial Control Systems Cybersecurity: Approaches, Limits and Further Research

Since the beginning of the century, Industrial Control Systems (ICS) are sujbected to attacks targetting their actuator controls. Although active research has been done, most of the approaches fail to secure them from strikers with high automation knowledge due to their environment and requirements. This paper provides a ICS comprehensive view, outlines the existing works and presents the authors' cybersecurity vision as well as the approach developed by G-SCOP Center of Research. From its deficiencies, further investigation is pointed out by giving the orientation for designing behavioral model based Intrustion Detection System (IDS) based on the equipment degradation and addressing one of the limitation of the current approach on a single action chain.
