Abstract

This application discloses a method for security auditing of communication messages in an industrial control system, which includes: issuing an operating machine configured with configuration software through a security operation and maintenance management platform in advance; when monitoring the operation of the configuration software by the operator, Obtain the current communication message of the manipulator; perform protocol analysis on the current communication message and generate a data sequence to be matched; match the data sequence to be matched according to a preset rule base to determine whether the current communication message is Safety. By monitoring the operator's operation of the configuration software, and obtaining the data sequence to be matched according to the generated communication messages, and then matching the data sequence to be matched with the data in the rule base, the security of the industrial control system is realized. audit.

Description

technical field [0001] The present application relates to the technical field of industrial control, in particular to a communication message security audit method in an industrial control system. Background technique [0002] With the continuous deepening of the informatization process in the industrial field, the industrial control systems of various enterprises have become increasingly complex, and the safety problems caused by illegal operations of operators with different backgrounds have become increasingly prominent, mainly manifested in: hidden dangers of internal personnel operations, the first Hidden safety hazards of third-party maintenance personnel, uncontrollable risks of violations, etc. Once a safety problem occurs in the operation, it will bring huge losses to the enterprise. Therefore, only by strengthening the operation supervision, operation audit and strict control in advance of terminal operators can the problem be solved from the source. Traditional ...
