Executive Summary

Cyber-Physical Systems (CPS) has been at the core of critical infrastructures and industrial control systems for many decades, and yet, there have been few confirmed cases of computer-based attacks. The authors discuss three key challenges for securing cyberphysical systems: understanding the threats, and possible consequences of attacks, identifying the unique properties of cyber-physical systems and their differences from traditional IT security, and discussing security mechanisms applicable to cyberphysical systems. In particular, the authors analyze security mechanisms for: prevention, detection and recovery, resilience and deterrence of attacks.
