Abstract

An approach for the design and placement of Intelligent Checkers (ICs) is presented along with an application to enhance the security and safety of a water purification system. Each IC, a smart sensor with a one-way outgoing communication over the network, monitors in real-time the status of one or more physical processes and raises an alarm when the monitored process measurements violate predefined constraints. ICs are structurally and behaviorally independent of the cyber-portion of a Cyber Physical System (CPS) and hence are much less likely to be affected by cyber attacks than the control system that monitors and controls a CPS. Thus, ICs serve as devices orthogonal to an existing intrusion detection system and assist in the early detection of successful attacks through independent monitoring of physical processes.
