International audienceThe migration of modern Industrial Control Systems (ICS) towards information and communication technologies exposes them to cyber-attacks that can alter the way they function, thereby causing adverse consequences on the system and its environment. It has consequently become crucial to consider security risks in traditional safety risk analyses for industrial systems controlled by modern ICS. We propose in this paper a new framework for safety and security joint risk analysis for industrial control systems. S-cube (for SCADA Safety and Security joint modeling) is a new model-based approach that enables, thanks to a knowledge base, formal modeling of the physical and functional architecture of cyber physical systems and ...
