摘要
A method for detecting physical intrusion attack in an industrial control system based on analysis of signals on serial communication bus is provided. This method comprises of actively sending a detection signal to communication bus via a bus controller in a serial communication bus network, sampling and analyzing signals on the communication bus by a monitoring device, performing differential comparison with a standard signal stored in the monitoring device database, detecting an intrusion signal in difference signal based on noise reduction technology and weak signal detection technology, and according to a detection result of the intrusion signal caused by an external device to effectively determine whether there is an external malicious device in the system, and whether the system is subjected to a physical intrusion attack.
