Industrial control system intrusion detection processing method, system and device and storage medium

The embodiment of the invention provides an industrial control system intrusion detection processing method, system and device and a storage medium. According to the embodiment of the invention, the data separation of the industrial control system and the detection system is realized, the real-time operation data leakage of the historical access terminal in the industrial control system is avoided, the operation data security is improved, the detection model referring to different feature conditions is finally obtained through joint training as the intrusion detection model, and the detection efficiency is improved. The access terminal currently accessing the industrial control system is detected through the intrusion detection model, whether the current access terminal is abnormal or not is determined, the terminal identification precision is ensured, meanwhile, only the detection result of the detection model on the historical access terminal is transmitted between the detection modules, and the detection e
