Industrial control asset information acquisition method and device

Abstract

The invention relates to an industrial control asset information acquisition method and device, electronic equipment and a computer readable medium. The method comprises the following steps: scanning IP addresses in a preset IP segment to generate a survival host list; detecting a port of each IP address in the surviving host list to generate a detection result, the detection result comprising opening of a key port, opening of a key universal port and opening of other ports; determining an extraction mode of industrial control asset information corresponding to the IP address according to a detection result; and sending a preset message according to the extraction mode to obtain industrial control asset information corresponding to the IP address. According to the industrial control asset information acquisition method and device, the electronic equipment and the computer readable medium, when the industrial control asset information is acquired, the influence of the acquisition process on the original network environment can be reduced, the detection resource utilization rate and the information reuse rate are improved, and the time required for industrial control asset scanning is shortened.

Description

technical field [0001] The present disclosure relates to the field of computer information processing, and in particular, to a method, device, electronic equipment, and computer-readable medium for acquiring industrial control asset information. Background technique [0002] In today's society, the industrial control system is in a crucial position, because many infrastructures that guarantee the basic livelihood of the people are closely related to it. Therefore, it is very necessary to supervise the various industrial control equipment that make up the system, but most of the industrial control equipment is placed in some factories or production workshops with a complex environment, and it is necessary to check the equipment information and other operations through direct contact. Waste of time and very difficult, and does not meet the actual production regulations. At present, most industrial control devices communicate with other devices or upper computers through LAN, ...

AI Technical Summary

Problems solved by technology

This scanning method requires a given IP segment in all occasions, and the ease of use is slightly lacking; and using full-port scanning and probing, on the one hand, when the number of IPs is large, it takes a lot of time to complete the probing process. The time is too long, and the scanning takes up a huge amount of resources in all aspects

On the other hand, due to the fact that a large number of packets (such as TCP SYN packets) are sent out at the same time for full port scanning, a large amount of irrelevant traffic will be introduced into the network environment, and there are risks such as packet loss of original business traffic and network interruption caused by network congestion; further Yes, when the asset information is stored, because the industrial control equipment may open multiple key protocol ports at the same time, the acquired asset information will appear as one IP device, corresponding to multiple assets, which may lead to inaccurate stored information and Coverage occurs
