Problems solved by technology

When a problem occurs in the industrial control system, all the communication data recorded in the audit can only be judged one by one to determine the communication data that caused the problem, and the troubleshooting efficiency of faults or threats is low.
This will lead to huge losses for industrial control systems with extremely high real-time requirements

Abstract

The invention discloses a communication data security audit method and device for an industrial control system. The method comprises the steps of: parsing acquired communication data to determine service behavior data which the communication data comprises; according to the service behavior data, determining a service rule set which needs to be met by the industrial control system when a service behavior is executed; and judging whether a current state of the industrial control system meets the service rule set, and carrying out corresponding recording. The communication data security audit method and device disclosed by the embodiment of the invention have the beneficial effect that when the communication data is audited, not only a communication behavior of the communication data but also the service behavior which the communication behavior represents need to be determined so as to judge whether the service behavior accords with the corresponding service rules and carry out recording. Therefore, when the industrial control system has a problem, communication data causing the problem can be determined from the recorded communication data which do not accord with the service rules. Fault or threat checking efficiency is promoted, and time is saved for recovering the industrial control system as soon as possible.

Description

technical field [0001] The invention relates to the field of industrial control security, in particular to a communication data security audit method and device for an industrial control system. Background technique [0002] In the industrial control system, various intelligent electronic devices (Intelligent Electronic Device abbreviated as IED) communicate through communication protocols. In order to realize the traceability of the behavior of the industrial control system, identify dangerous operations, and ensure the security of the industrial control system, it is necessary to perform a security audit on the communication data in the industrial control system. [0003] The traditional security audit analyzes the communication data according to the communication protocol, records the field information in it, and forms an audit record of the communication behavior. The traditional security audit method does not consider the business functions of the industrial control sy...
