Industrial controlling network safety protecting method

Abstract

The invention discloses an industrial controlling network safety protecting method. The industrial controlling network safety protecting method is capable of improving industrial controlling network safety, convenient to communicate, capable of preventing external attack and invasion, and effectively protecting industrial controlling system and safety of industrial equipment. The industrial controlling network safety protecting method comprises the steps as below: processing an information system of an industrial enterprise in hierarchy; adopting safety protecting strategy procedures for data exchanging of the industrial controlling hierarchies; dividing the industrial controlling hierarchies into a plurality of automated unit regions and using a firewall for region separation; blocking potential communication ways of a production executive hierarchy to the industrial controlling hierarchy; adopting an industrial safety management platform module to build the center of configuration, management, analysis, warning and auditing of the industrial controlling hierarchy. The industrial controlling network safety protecting method is applied to the field of industrial controlling network.

Description

technical field [0001] The invention relates to a safety protection method for an industrial control network. Background technique [0002] The industrial control system is a system composed of various automatic control components and process control components that collect and monitor real-time data. More than 80% of my country's key infrastructure relies on industrial control systems to achieve automated operations. Industrial control networks have become An important part of the national security strategy, once there is a loophole in the information security of the industrial control network, it will cause major hidden dangers to industrial production and national economic security. Therefore, government departments at all levels in our country attach great importance to it, emphasizing that the information security of industrial control systems is related to industrial production Operation, national economic security, and people's life and property safety, it is necess...

Problems solved by technology

This patent adopts a 3-host structure and a three-layer protection strategy, which has high investment and management costs, and the various monitoring equipment used are relatively complicated, which cannot meet the large demand of industrial control networks.

[0005] At present, the production management system and the control system are in the production control network together, and support information exchange with each other, without logical isolation and information detection measures, such as figure 1 As shown, the production control network and the operation and management network are logically isolated through a firewall and monitor the communication data between each other. However, there are viruses or Trojan horses from the Internet or other media in this structure. Information security risks of the base launching an attack on the production control network through the firewall
