An intrusion prevention system can be embedded in an industrial controller to detect possible attacks on the corresponding physical system of the industrial controller. The intrusion prevention system can analyze the payload of network packets received at the industrial controller and predict what harm the payload of the network packet could cause to the physical system if executed by the industrial controller. To predict how the payload of a network packet may affect the physical system, the intrusion prevention system can perform a simulation with the payload of the network packet. The simulation can incorporate a model of the physical system, a copy of the logic used by the industrial controller and information relating to the current state of the system. The result of the simulation can be new predicted states for the physical system that can be evaluated to determine if a safety violation has occurred.
