A Human-Integrated Tool for Proactive and Reactive Security in Cyber-Physical Systems

We present a comprehensive defense software for cyber-physical systems, comprising both proactive and reactive mechanisms. Specifically, the demonstrated tool allows a human operator to remain aware of the system’s health and operation, while an autonomous subsystem applies a switching rule based on the principles of Moving Target Defense, rendering the system more unpredictable but stable nonetheless. Finally, the man-machine interaction implements a trust metric, that allows either the autonomous mechanism or the human agent to have more control over the system based detection and mitigation history. We describe the interface of the security software, while the case of an autonomous aircraft is used to showcase the efficacy of the software.
