Cloud-edge collaborative industrial control network safety protection method based on strategy library

Abstract

The invention provides a cloud-edge collaborative industrial control network safety protection method based on a strategy library. The method comprises the steps: generating an abnormal condition recognition rule library through a generative adversarial network (GAN) of a generative model network, namely a long short-term memory (LSTM) network, and a novel discrimination model network, namely a DendriteNetworks DD, at a cloud end; and then deploying the rules to corresponding edge ends, matching a corresponding coping strategy for each rule, and finally forming a cloud-edge collaborative strategy library to meet the low-delay safety protection of the industrial control network. A side end of the method comprises a data collection module and a strategy library module, and a cloud end comprises a data processing module, a generative adversarial network module, a rule generation module and a rule library module. Meanwhile, the rule base and the strategy base further comprise prediction rules generated by time sequence features extracted by the long and short-term memory network and recognition rules generated by the dendritic network. Policy corresponding to different rules can be set by an administrator of the industrial control system.

Description

technical field [0001] The invention belongs to the field of anomaly detection of industrial control systems, and in particular relates to a policy library based on cloud-edge collaboration technology to meet the relatively stringent low-time-delay requirements of industrial control system security. Background technique [0002] The use of information technology in my country's industrial field involves almost every aspect of industrial production. The development of industrial control systems can be said to be very rapid, and it can even be said to be an indispensable part of my country's modern industrial production. However, due to the development of networking and informatization of industrial control systems, more and more loopholes in the design of the original system are exposed, which magnifies the security risks and intrusion threats faced by the system. The types of loopholes include but are not limited to communication protocol loopholes, operation System vulnerab...
