Abstract

The invention discloses an industrial control equipment fingerprint extraction and identification method based on active detection, and the method comprises the following steps: S1, scanning a specified IP segment or port through an industrial control protocol script, carrying out the verification and formatting of a scanning result through each protocol, and carrying out the matching with fingerprint information loaded in a memory according to a protocol name; s2, if the matching is successful, identifying the manufacturer, type and model information of the equipment, and storing the scanned equipment information in a database; s3, if the matching is not successful, extracting the manufacturer, type, model and fingerprint unique identifier information of the equipment through retrieval, and after the information is verified to be correct, inputting the information into a fingerprint database; and S4, periodically executing a task of loading the fingerprint information in the fingerprint database to the memory through the system, so that the fingerprint information can be matched with the scanning data in time.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to a method for extracting and identifying fingerprints of industrial control equipment based on active detection. Background technique [0002] When it comes to industrial control, most people will think of a series of huge vocabulary such as enterprise, manufacturing, factory, etc., but it is closely related to the life of each of us. In our daily life, everything from Internet TV, set-top boxes, smart water heaters, smart water meters, ATM machines, traffic light control, to weather forecasts, building video surveillance, aviation flight control, earthquake early warning, etc., are inseparable from industry. Control system support. [0003] With the advent of the fourth industrial revolution, traditional industries are gradually developing towards the intelligentization of the Internet model, and industrial control systems have become an indispensable part of people's...
