Abstract

The invention provides an industrial flow detection method and device, equipment and a medium, and the method comprises the steps: carrying out the protocol recognition of a message in industrial flow, obtaining a protocol of the message, and enabling the protocol of the message to be represented by a corresponding protocol number; according to the source address, the destination address and the protocol number of the message, searching a formal node of a first-level linked list in a pre-generated multi-level linked list; if the first-level linked list formal node is found, extracting the depth content characteristics of the message according to the matching depth of the first-level linked list formal node; and according to the matching depth of each stage of linked list formal node, matching the depth content features with the depth content features of the plurality of stages of linked list formal nodes in the multi-stage linked list stage by stage, and if a matching condition is met,allowing the message to pass. According to the invention, the industrial flow is analyzed and identified by extracting the deep content characteristics of the message in the industrial flow.

Description

technical field [0001] The present disclosure relates to the technical field of industrial safety, in particular to a method, device, equipment and medium for industrial flow detection. Background technique [0002] Industrial control systems are widely used in industrial production. The working process of industrial control systems will generate industrial flow data. In order to ensure the safety and stability of industrial production, it is necessary to detect industrial flow data and determine whether the industrial flow data is normal data or abnormal. data. [0003] The existing technologies for detecting abnormal traffic data can be mainly divided into three categories: one is port-based method, which checks packets according to the port number in the traffic data; the other is the method based on traffic characteristic statistics, through machine learning algorithm Classify the traffic into known categories; the third is the method based on the original payload, and ...
