Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The present invention designs a protocol fuzzy testing method based on a serial connection method, through which a fuzzy testing device connected in series on the communication link between the terminal area and the server area realizes a two-way test for the terminal and the server. In practical applications, For the connection topology of the fuzzing device relative to the terminal area and server area such as figure 2 In the design, the terminal area and the server area pass through the switch and the router respectively, and then connect to the fuzzing test device, that is, the fuzzing test device is serially connected to the communication link between the terminal area and the server area, and in practical applications, the structural design of the fuzzing test device Refer to as image 3 design.

Abstract

The invention relates to a protocol fuzzy test method based on a tandem connection mode. According to the fuzzy test tool, the problems of limited test functions, low test efficiency and insufficienttest depth in a traditional fuzzy test tool are solved, the series connection test is based on the established connection, repeated connection establishment of the traditional test is avoided, the test time is shortened, and the test efficiency is improved; The serial connection test has the capability of testing the client side and the server side at the same time; According to the fuzzy test method and device, the defect that a traditional fuzzy test engine can only test a server is overcome, the test availability is improved, in addition, based on a matched fuzzy test mechanism, the fuzzy test is allowed to start from a place where intervention is desired and time, the test flexibility is improved, and more potential vulnerabilities can be excavated.

Description

technical field [0001] The invention relates to a protocol fuzzy testing method based on a serial connection mode, and belongs to the technical field of meteorological radar signal detection. Background technique [0002] The industrial control system is the basic component of the automatic production of my country's important infrastructure. The importance of security is evident. However, due to many factors such as core technology limitations, complex system structure, and lack of security and management standards, it may be attacked by hostile forces and commercial espionage at any time. , cybercriminal gangs, resulting in increasingly serious security threats, in view of these security threats, the current fuzz testing tools came into being, used to mine unknown vulnerabilities of equipment and verify known vulnerabilities. [0003] Traditional fuzz testing tools mainly test the server, but do not have the ability to test the client. Attackers can easily exploit the poten...
