A Visualization Method of Industrial Control Network Topology Structure

Abstract

The invention relates to an industrial control system and aims to provide a method for visualizing the topology structure of an industrial control network. The method for visualizing the topology structure of an industrial control network includes the steps of: deploying a platform in an industrial control network that needs to be topologically performed to ensure that all devices in the industrial control network can be reached; The device scans and saves the sorted node information into the database; uses the integrated node information to obtain the topology line; returns the port connection information of each device according to the obtained topology line, and draws the connection relationship between the nodes of each device. And finally get the topology network diagram of the industrial control network. The invention adopts a very simple way, that is, obtains the network structure that needs topology through the most basic ARP protocol and SNMP protocol, and displays the structure on the visual interface, so as to avoid possible logical errors in complex algorithms.

Description

technical field [0001] The invention relates to the field of industrial control systems, in particular to an industrial control network topology visualization method. Background technique [0002] The arrival of "Industry 4.0" and the proposal of the "Made in China 2025" action plan have accelerated the integration process of my country's industrialization and informatization, improved social production efficiency, and also made more and more industrial control companies that were originally in a closed environment Devices are exposed to the Internet and directly bear the threat of attacks from the Internet. Compared with traditional information security, the consequences of industrial control system security problems are often more serious, even catastrophic, such as causing large-scale shutdowns, casualties, equipment and environmental damage, etc. [0003] At present, all countries regard cyberspace security as an important part of national security, and the security of t...

Problems solved by technology

[0005] 1) The management of industrial security equipment is complicated: when operating and maintaining a large number of industrial security equipment, security management personnel need to log in and manage them one by one, resulting in failure to timely check when problems occur in the industrial network, and need to manually locate and then log in to the corresponding security equipment to judge The cause of the problem, which prolongs the downtime of the production system

[0006] 2) Industrial security equipment cannot be coordinated: With the strong demand for industrial information security and the increase of industrial security equipment, these security lines only defend against security threats from certain aspects, forming "islands of security defense" that cannot produce synergistic effect

However, there are the following disadvantages: a lot of probe nodes need to be arranged, and then the data of all nodes are summarized and sorted, and the sorting algorithm adopted is relatively complicated
