Embodiment Construction

[0041] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0042] The applicant found that the existing learning methods can only conduct simple behavior learning on single-packet packets of the industrial control protocol, lack of illegal attack detection and processing of packet combination content, and the whitelist strategy formed after learning may be missed Abnormal write value messages have poor usability. Therefore, the embodiment of the present application provides a method for generating an industrial control strategy that perceives abnormal write register behaviors through combined detection to solve the above problems.

[0043] Please refer to figure 1 , figure 1 It is a schematic flowchart of a method for generating an industrial control strategy provided in the embodiment of the present application. The specific steps of the method for genera...

Abstract

The present application provides a method and device for generating an industrial control strategy, an electronic device and a storage medium, and relates to the technical field of communication. The method includes: receiving a plurality of industrial control protocol messages; determining the content change rate of the write operation of every two adjacent industrial control protocol messages in the multiple industrial control protocol messages; determining based on the content change rate Whether to learn the industrial control protocol message corresponding to the write operation, so as to generate an industrial control strategy. The method detects and processes illegal content attacks through the combination of multiple industrial control protocol message packets, finally makes the learning result more accurate, and improves the usability and credibility of the learning-generated strategy.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular, relates to a method, device, electronic device and storage medium for generating an industrial control strategy. Background technique [0002] Different from traditional information networks, the communication process of industrial control systems has the characteristics of small traffic but high value. The data contained in the communication process are basically process data and control data, and there are no other unauthorized protocol access processes, and the path is relatively fixed. Due to the above factors, attack behaviors in industrial networks are usually based on legal paths, legal protocols, and even legal behaviors. This requires industrial control firewalls to not only have the access control functions of traditional firewalls, but also be able to conduct in-depth control over industrial communication protocols. In-depth analysis of the contents ...
