Description: Water distribution systems (WDSs) operation relies on a set of rules and conditions aimed at maintaining a reliable wate r supply. The WDS operation is often controlled by supervisory control and data acquisition (SCADA) and programmable logic controllers (PLCs). As such, with the SCADA becoming a central component of WDSs these systems can be subjected to cyber-attacks. This paper offer a methodology for identifying cyber-attacks based on logical rules that are based on detailed hydraulic understanding of the WDS combined with a machine learning event detection system for identification of complex cyber-attacks that cannot be fully identified by the hydraulic based rules alone. © ASCE.
