Abstract

The invention provides an industrial control system protection method and an industrial control system protection device, and relates to the technical field of safety protection for an industrial control system. The industrial control system protection method comprises the steps of obtaining adversarial samples trained by an adversarial sample generation model; preprocessing the adversarial samples and normal samples by adopting a hybrid coding mode; importing various combinations of the preprocessed adversarial samples and normal samples into the industrial control system to carry out adversarial training on the industrial control system so as to enable the industrial control system to have a false information defense ability. Through setting up the adversarial sample generation model andtraining model parameters, control parameters in the industrial control system in an input model are trained by using the trained adversarial sample generation model to obtain the adversarial samples, and the adversarial samples are imported into the industrial control system for adversarial training so as to improve the defense ability of the industrial control system.

Description

technical field [0001] The invention relates to the technical field of safety protection of industrial control systems, in particular, to an industrial control system protection method and an industrial control system protection device. Background technique [0002] Industrial Control Systems (ICS) are used to supervise and control many industrial systems and processes. Common ICS are used in critical infrastructure such as chemical plants, power generation and transmission and distribution systems, water distribution networks, and wastewater treatment facilities. ICS typically contain sensors and actuators controlled by a Programmable Logic Controller (PLC), which are themselves managed by a Human Machine Interface (HMI). [0003] In the prior art, a supervisory control and data acquisition system (Supervisory Control And Data Acquisition, SCADA), as a kind of ICS, usually includes different stations distributed in the region. Most SCADA network traffic is generated by au...
