Abstract

The invention relates to a protocol fuzz testing method and system. The method comprises the steps of collecting data packets communicating with a test target according to functions of the test target, and performing permutation and combination according to different functions to generate a data packet combination corresponding to each function; performing variation on a preset number of bytes randomly extracted from each data packet combination to generate a varied data packet combination; sending the varied data packet combination to a test target, extracting the varied data packet causing a fault of the test target, and compiling the varied data packet into a script file; sending the script file to a test target, and detecting whether the test target fails or not; and if so, determining that the varied data packet causing the test target fault is a potential vulnerability data packet. The method is a new test process aiming at the protocol, a fuzz test is carried out on the protocol from the dimension of a penetration test through the data packet combination, the dimension of test case generation is expanded, and the probability of vulnerability discovery is increased.

Description

technical field [0001] The invention relates to the technical field of fuzz testing, in particular to a protocol fuzz testing method and system. Background technique [0002] At present, the fuzzing test for the protocol is to fuzz the composition structure of a single data packet message, generate a single data packet test case based on different algorithms, and send it to the target device for testing. This single packet fuzzing method has the problem of low vulnerability discovery probability. Contents of the invention [0003] The purpose of the present invention is to provide a protocol fuzzing testing method and system to increase the probability of loophole discovery. [0004] To achieve the above object, the present invention provides the following scheme: [0005] A protocol fuzz testing method, comprising: [0006] Collecting data packets communicated with the test target according to the function of the test target; [0007] Arranging and combining the colle...
