FADa-CPS—Faults and Attacks Discrimination in Cyber Physical Systems

Running autonomous cyber physical systems (CPSs) in a safe way entails several complex activities that include monitoring the system for ongoing attacks or faults. Root cause analysis is a technique used to identify the initial cause of a cascading sequence of faults affecting a complex system. In this paper we introduce FADa-CPS, an architecture for root cause analysis in CPSs whose goal is identifying and localizing faults caused either by natural events or by attacks. The architecture is designed to be flexible such to adapt to evolving monitored systems.
