Example Embodiment

[0035] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0036] figure 1 An industrial control dynamic defense method according to the first embodiment of the present invention is shown, where the method shown starts at step S101. In step S101, the industrial network flow data is analyzed in detail, and the industrial network flow data is cleaned to obtain clean industrial control protocol flow data. In step S102, it is judged whether the obtained industrial control protocol flow data is a known industrial control protocol. If the obtained industrial control protocol flow data is known, then the industrial control protocol flow data is ignored and the method ends...

Abstract

The invention provides an industrial control dynamic defense method. The method comprises the following steps: cleaning industrial network flow data to obtain industrial control protocol flow data; judging the industrial control protocol flow data; recording a protocol data format of an unknown industrial control protocol, and obtaining a data interval range of the industrial control protocol; intelligently filling protocol contents according to the interval range, and integrating the protocol format and the filled data to form a learning result; generating a dynamically changing white list according to the learning result; and performing industrial control dynamic defense according to the white list. The invention further provides an industrial control dynamic defense system. The industrial control dynamic defense method and system provided by the invention has the advantages of being able to accurately recognize industrial private protocols, high in compatibility and high in protection precision, etc.

Description

technical field [0001] The present invention relates to the field of industrial control, and more particularly relates to a dynamic defense method and system for industrial control. Background technique [0002] Industrial control technology is a kind of use of computer, control theory, instrumentation and other information technology to realize detection, control, optimization, scheduling, management and decision-making of industrial production process, so as to increase production, improve quality, reduce consumption and ensure safety. comprehensive technology. [0003] Generally, applications in the field of industrial control must meet the following requirements: availability, integrity, and confidentiality, and the design of industrial equipment is usually designed according to the principle of availability priority, which restricts data confidentiality in industrial environments. significant safety hazard. When a major incident occurs in the national infrastructure, ...
