Problems solved by technology

The DCS system is directly and indirectly connected with the external Internet, so that external bad intrusions and virus infections may cause damage to the DCS network
[0005] There are loopholes in the various operating systems (such as Windows) used by the DCS system, and intruders use these loopholes to carry out network attacks, but at present, various DCS networks have not taken anti-virus and Trojan horse measures

Abstract

The invention relates to an information security protection system for a DCS system, and the system comprises an industrial security isolation gatekeeper which is disposed at the network boundary of a DCS network and an SIS system, and is used for isolating the DCS system from the SIS system, and protecting the security of the network boundary of the DCS system; an industrial network auditing system which is deployed in a main switch bypass of the DCS system and is used for network full-flow auditing, alarming and analyzing; an industrial log auditing system which is deployed in the DCS and is used for carrying out log data acquisition, classification and analysis on the safety equipment, the network equipment, the host system and the database; and an industrial intrusion detection system which is deployed at a bypass of the SIS three-layer core switch and is used for monitoring industrial network transmission data in real time and performing intrusion detection and alarm on network data traffic. According to the invention, safe and stable operation of the DCS system information network can be ensured.

Description

technical field [0001] The invention belongs to the technical field of thermal power generation, and in particular relates to an information security protection system used in a DCS system. Background technique [0002] DCS (Distributed Control System) is the abbreviation of Distributed Control System. Based on microprocessor, it is a new generation of instrument control system that adopts the design principles of decentralized control function, centralized display operation, taking into account the design principles of division and autonomy and comprehensive coordination. [0003] With the development of modern informatization of enterprises, the future development of DCS technology will inevitably move towards the field of informatization, not only to provide traditional production data to front-line employees, but also to have various information platforms for uploading production data. From this aspect, the DCS system should not only serve for the collection and processi...
