Abstract
An overlay cyber security networked system and method that includes one or more devices configured to monitor physical-level signal information to determine a cyber security threat or breach event based on activity occurring with physical signals present at one or more components of a Process Control Network (PCN), enabling forensic analysis. The overlay cyber security networked system also provides information needed for real-time incident management by capturing logs of relevant events at various points in the network hierarchy starting at the analog signaling from the sensors to detect unauthorized variances in operational parameters, thereby providing a defense in depth security architecture for PCN-based systems.
