Problems solved by technology

[0005] Although Achilles has become a very mature product in the industry, it also has obvious limitations. The industrial control protocols supported by Achilles are limited. Once the protocol type needs to be added, the development cycle is relatively long, and equipment manufacturers often have new protocols or custom protocols. testing requirements, and need to customize flexible contract delivery mechanism according to different protocols, so it is difficult for Achilles to meet such flexible testing requirements

Abstract

The invention discloses an xml-based fuzzy test language protocol test script and a test engine. The protocol test script comprises a test script automatically generated based on a fuzzy test languageand a state machine according to industrial control and Internet of Things protocol message formats and a monitoring script generated based on the fuzzy test language and the state machine and aimingat the state of tested equipment. According to the xml-based fuzzy test language protocol test script and a test engine, the test script and the monitoring script are automatically generated based onthe language; and the test engine can automatically parse the script language to generate the test data packet and send the test data packet to the tested equipment to complete the test task, the efficient fuzzy test language enables the detection system to expand a new protocol very conveniently, and the test engine architecture also guarantees the flexibility and expansibility of a packet sending mechanism.

Description

technical field [0001] The invention relates to the technical field of test scripts and test engines, in particular to an xml-based fuzzy test language protocol test script and test engine. Background technique [0002] In recent years, several major incidents of industrial control systems being attacked by hackers have occurred in the world, causing serious consequences and shocking the world. Moreover, such cyber attacks are increasing, exposing serious deficiencies in the security protection of industrial control systems. China has also begun to gradually pay attention to the security issues of industrial control systems. As more and more security flaws of industrial control networks are exposed, security issues have become a major problem for industrial control networks. To improve the security of the industrial control network, we must first improve the security of various devices in the industrial control network. Through the attack test, it is an effective method to...
