Abstract: System for detecting a cyber-attack of a SCADA system managed plant. Each industrial computerized device of the system comprises a processor configured with a data validation module to determine whether data flow outputted from a SCADA-connected controller is authentic, and with an alert issuing mechanism activated following detection that the outputted data flow is indicative of a cyber-attack. The at least one dedicated industrial computerized device is operable to passively monitor in parallel data communicated between each of the controllers and the SCADA system including the outputted data at the nearest points of each of the controllers; seek mismatches between the plant state and the physical operation model; if a mismatch is detected, determine whether the mismatch is indicative of a cyber-attack perpetrated with respect to one of the controllers or an operational malfunction; and upon detecting a cyber-attack, activate the alert issuing mechanism to issue a security alert.
