Abstract

The invention relates to a detection method and device for a networked industrial control system, computer equipment and a medium. The detection method of the networked industrial control system comprises the following steps: reading a survival port from a survival port library, and detecting first feature information of industrial control equipment corresponding to the survival port by using a detection script; performing fuzzy matching on the corresponding industrial control equipment in an industrial control equipment fingerprint library by using the first feature information; acquiring second feature information of the industrial control equipment according to the matched industrial control communication protocol used by the industrial control equipment; and generating fingerprint features of the industrial control equipment according to the first feature information and the second feature information, and storing the fingerprint features in a fingerprint library of the industrialcontrol equipment. According to the invention, the problem of insufficient detection depth of a search engine on the industrial control system in related technologies is solved, and the detection depth on the industrial control system is increased.

Description

technical field [0001] The present application relates to the field of network security, in particular to a detection method, device, computer equipment and computer-readable medium of a networked industrial control system. Background technique [0002] Informatization and industrialization of modern industrial production enterprises have been highly integrated, which means that industrial control systems are becoming more and more open and interconnected, and it is almost impossible for industrial control systems to be completely isolated from the outside world. [0003] Corresponding to the severe security situation mentioned above, due to the emergence of hacker conferences, white hat communities, and open source communities, it is becoming easier to obtain attack methods for industrial control systems. Obtained through public or semi-public channels, these greatly reduce the difficulty of cyber attacks against industrial control systems. Therefore, timely discovery of i...
