A Brief Survey of Security Approaches for Cyber-Physical Systems

The security of Cyber-Physical Systems (CPS) has been recently receiving significant attention from the research community. To this end, this paper sheds the light on a number of security approaches for CPS from two perspectives, namely, control-theoretic and cyber security. Further, threat detectors in various CPS environments are highlighted and discussed. The aim is to demonstrate the lack of coherent approaches that systematically tackle both security aspects of such systems, in addition to pinpointing several insightful research gaps that endeavor to shape future CPS security solutions.
