It is assumed that the observations represent a linear superposition of unknown nuisance parameters (stochastic or deterministic), random noise and a system parameter abruptly changing its current value from nominal to abnormal at an unknown but non-random change-point. It is assumed that this statistical model characterizes the cyber-physical...

This paper addresses the problem of detecting cyber/physical attacks on Supervisory Control And Data Acquisition (SCADA) systems. The detection of cyber/physical attacks is formulated as the problem of detecting transient changes in stochastic-dynamical systems in the presence of unknown system states (often regarded as the nuisance parameter)....

Supervisory control and data acquisition (SCADA) systems are highly distributed systems used to control and monitor geographically dispersed assets-often scattered over thousands of square kilometers-in which centralized data acquisition is critical to system operation [1]. These large-scale industrial control systems (ICSs) have been playing...
