Abstract

A system for establishing intrusion detection logic for a Programmable Logic Controller (PLC) by receiving control program code embodying the control logic of the PLC; processing the control program code to determine a transition model defining one or more PLC outputs based on inputs to the PLC; and generating the intrusion detection logic based on the transition model.
