Abstract

The invention discloses a three-mode heterogeneous redundant industrial control security gateway system and an intrusion sensing method thereof. The system provided by the invention comprises a data packet external IO module, three heterogeneous redundant industrial control security gateway execution modules, a comparison module, a data packet internal IO module, an intrusion sensing module and asystem configuration module. The invention is capable of detecting the intrusion to the industrial control gateway in time and preventing the attack behaviors caused by the design or implementation ofthe defect by using the system in the normal translation processing of the industrial control data packet, and performing the intrusion response processing without normal service interference.

Description

technical field [0001] The invention belongs to the technical field of industrial information security, and relates to a three-mode heterogeneous redundant industrial control security gateway system and an intrusion sensing method thereof. Background technique [0002] With the popularization of the application of information technology and network technology in industrial systems, the security of industrial information systems is a direct threat to the current industrial information systems. As an important line of defense of the security system, the traditional industrial control security gateway defends against hacker attacks through access control. However, as more and more operating system vulnerabilities and application system vulnerabilities are discovered, the industrial control security gateway faces two problems: [0003] (1) It is broken by itself. Obviously, once the security gateway is breached, the industrial control network loses a powerful protective wall. ...
