Abstract

The invention discloses an industrial control protocol data stream processing method, device and equipment and a storage medium, relates to the technical field of industrial control network security testing, and is used for solving the problems of large error and missed testing caused by flow static playback and improving the industrial control flow simulation effect. The method comprises the following steps: obtaining an industrial control protocol behavior request; wherein the industrial control protocol behavior request is used for indicating to send an analog data stream corresponding to a target industrial control protocol behavior to target industrial control network security equipment; generating an industrial control protocol request data stream corresponding to the industrial control protocol behavior based on the industrial control protocol behavior and at least one pre-constructed industrial control protocol template library; wherein the industrial control protocol template library comprises an industrial control protocol template of an industrial control protocol behavior corresponding to at least one industrial control protocol; and calling a data forwarding component, and sending the industrial control protocol request data stream to target industrial control network security equipment.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of industrial control network security testing technology, and provides an industrial control protocol data flow processing method, device, equipment and storage medium. Background technique [0002] Industrial control network security equipment, such as firewalls, auditing and other equipment can effectively guarantee the security of industrial equipment control process, so the requirements for the function and performance of industrial control network security equipment are relatively high. At present, in order to test the function of industrial control network security equipment, a test computer is often connected to the device under test, and then static playback is performed based on the captured network traffic, so as to simulate the communication situation of industrial equipment in real industrial communication. [0003] However, due to the changes b...
