Security in Cyber-Physical Systems

Information Security is a domain of IT that has a well developed body of knowledge, and a cadre of practitioners with significant experience in securing IT systems. Cyber Physical Systems (CPS) also has a well developed body of knowledge and a well trained cadre of professionals that have been successfully running systems for years. These are two separate groups that would benefit from working together rather than in a hierarchical management structure. Securing CPS is a new challenge as systems become interconnected. New technologies will be needed, but much can be gained from existing knowledge, if it is properly shared between these two groups. This paper examines this idea in light of previous security examples.
