Achieving security in Cyber-Physical Systems (CPS) has become a critical problem. Due to their ubiquity and the essential role they play in modern societies, CPS such as the smart grid, transportation networks, medical systems, and water distribution systems are a target for malicious attackers. While significant efforts are being made to achieve resilience in CPS, the field of CPS security as a whole suffers from fragmentation. In particular, there is often a sharp divide between mainstream security and privacy and tradition system theoretic techniques.
