Network anti-intrusion method and system for industrial automation operation

Abstract

According to the industrial operation-oriented network anti-intrusion method and the industrial operation-oriented network anti-intrusion system provided by the invention, by analyzing network intrusion threats, anti-intrusion measures are specifically taken, so that the purpose of maintaining network security is achieved, and the stability of intelligent industrial equipment is improved. The method specifically comprises the following steps: analyzing and acquiring a current overall communication protocol based on an industrial control system in a current application; constructing an intrusion detection model, and receiving communication data; analyzing the communication data by using the intrusion detection model to obtain abnormal data; obtaining an intrusion type according to the abnormal data; and formulating a corresponding coping method according to the intrusion type. Wherein the load pressure in the operation process is reduced in a data dimension reduction mode. Besides, the intrusion detection result is uploaded to the block chain by means of instantiation and the like by utilizing the characteristics of decentralization and tampering difficulty of the block chain, so that a tampering prevention mechanism of the intrusion detection data is realized, and the security and credibility of the intrusion detection data are improved.

Description

technical field [0001] The invention relates to the technical field of network security of automatic control, in particular to a network anti-intrusion method and system for industrial automation operations. Background technique [0002] Based on the rapid development of Internet technology, in order to better realize data sharing and meet the basic source of data analysis, industrial automation control systems have gradually established a huge information exchange system through the Internet. The independent entity architecture gradually realizes data interaction based on Internet technology, breaking the phenomenon of information islands. [0003] However, the trend of the Internet of Everything has gradually increased the chances of peripheral attacks and intrusions into intelligent equipment, leading to the phenomenon of intelligent industrial equipment being invaded and programs being maliciously tampered with, resulting in production errors and substandard products of ...
