Abstract
A method for providing cybersecurity to an industrial system having multiple components includes monitoring communications across the components of the system and detecting a deviation in an expected communication state in a first component. Upon detection of a deviation, communication states of at least one other component in the system is observed. If a deviation is also detected in the other component, then the deviation is deemed to be unauthorized. If no other deviations are detected in other components, the original deviation is deemed to be benign. Detecting a deviation includes comparing an expected communication state based on a baseline to the current communication state, the communication state may be based on a communication's content or a pattern of communication actions.
