Abstract: A system to protect a fleet of industrial assets may include a communication port to exchange information with a plurality of remote industrial assets. An industrial fleet protection system may receive information from the plurality of remote industrial assets or a cloud-based security platform and calculate, based on information received from multiple industrial assets, a current fleet-wide operation feature vector. The industrial fleet protection system may then compare the current fleet-wide operation feature vector with a fleet-wide decision boundary (e.g., separating normal from abnormal operation of the industrial fleet). The system may then automatically transmit a response (e.g., a cyber-attack threat alert or an adjustment to a decision boundary of an industrial asset) when a result of the comparison indicates abnormal operation of the industrial fleet.
