Abstract

One or more embodiments of the present specification provide an industrial control protocol analysis method, which is characterized by comprising: receiving unknown industrial control protocol data; identifying a message header, a data unit and a message tail from the unknown industrial control protocol data through an industrial control protocol analysis model, and analyzing a data type of each value domain and a label variable corresponding to the value domain in an industrial control system from the data unit in combination with the message header; and analyzing the unknown industrial control protocol data to obtain an analysis result of the unknown industrial control protocol data, wherein the industrial control protocol analysis model is obtained by establishing and training a decision tree model by utilizing a plurality of known industrial control protocol data.

Description

technical field [0001] One or more embodiments of this specification relate to the electrical field, and in particular, relate to an industrial control protocol analysis method, device, electronic device, and storage medium. Background technique [0002] Power industry control protocol identification technology is the basis of power industry control system and power equipment network traffic monitoring, intrusion detection, and power network security protection. With the development of power industry control industry, various new control systems and new control equipment continue to appear. These Most control systems and devices use proprietary communication protocols, and there are many types of protocols with different implementations, which brings great difficulties to the security protection of power networks. Currently, protocols are usually analyzed manually, but manual analysis of industrial control protocols is inefficient. Contents of the invention [0003] In vi...
