A visualization method of industrial control network topology structure

Abstract

The invention relates to an industrial control system, aiming at providing a visualization method of industrial control network topology structure. The visualization method comprises the steps of: deploying a platform into the industrial control network which needs topology to ensure that the equipment in the industrial control network can reach; according to the position of the platform in the industrial control network, scanning the equipment in the industrial control network by the timing task, and saving the node information in the database, using the integrated node information to obtainthe topological line;according to the obtained topological line, returning the port connection information of each equipment, drawing the connection relationship between each equipment node, and finally obtaining the topological network diagram of the industrial control network. The invention adopts a very simple way, that is, the network structure requiring topology is obtained through the most basic ARP protocol and the SNMP protocol, and the structure is displayed on the visual interface, thereby avoiding the logic error that may occur in the complex algorithm.

Description

technical field [0001] The invention relates to the field of industrial control systems, in particular to a method for visualizing the topology structure of an industrial control network. Background technique [0002] The arrival of "Industry 4.0" and the proposal of the "Made in China 2025" action program has accelerated the integration process of my country's industrialization and informatization, improved social production efficiency, and also made more and more industrial control in a closed environment. Devices, exposed to the Internet, are directly under attack threats from the Internet. Compared with traditional information security, the consequences of industrial control system security problems are often more serious and even catastrophic, such as large-scale shutdowns, casualties, and damage to equipment and the environment. [0003] At present, all countries regard cyberspace security as an important part of national security, and the security of the Internet 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
