Abstract
Systems and related methods for independent dissimilar cybersecurity monitoring of avionics and other critical control systems (CCS) incorporate security monitors with dissimilar processors to the CCS. The security monitors learn, using AI techniques, to emulate one or more target CCS by learning to predict, or generate, equivalent outputs or equivalent behaviors based on the same control inputs. The security monitors may monitor the CCS, or its individual internal and external subsystems, for cybersecurity faults by observing the control behaviors or outputs of the CCS for a given control input or comparing the control behaviors or outputs to expected normal behaviors and outputs previously learned by the security monitor. Deviance, or lack of equivalence, of observed control behaviors or outputs to the expected normal behaviors or outputs may indicate a cyberintrusion fault of the CCS or of a particular subsystem.
