Abstract

An embodiment of the present invention provides a method and system for performing fuzz testing on a distributed system, the method comprising: obtaining the preset source code of the program to be tested in the system to be tested, using a compiler to compile the preset source code and Merge to obtain the intermediate representation of the whole program; insert the intermediate representation of the whole program to obtain the intermediate file after the insertion; perform code generation on the intermediate file after the insertion, and output several binary executable files; based on the Several binary executable files start the system under test by the test tool, and initialize the system under test; when the system under test is initialized, the test tool starts fuzz testing to determine whether the system under test exists abnormal. The embodiment of the present invention effectively improves the software quality of the distributed system by automatically applying the fuzzy test to the test of the entire distributed system, which is of great significance to system security.

Description

technical field [0001] The invention relates to the technical field of automatic vulnerability mining, in particular to a method and system for fuzzing a distributed system. Background technique [0002] Software is a way for a computer to realize its specific functions, and the security of the software itself is the key to ensuring the security of the computer system. As a basic component of a large-scale software system, attackers often use the defects and loopholes of the distributed system itself to attack the computer system, steal key information, and cause property losses. Therefore, the security guarantee technology of the distributed system is very important. [0003] Fuzz testing is currently one of the effective methods for software security. The key idea of ​​fuzz testing is to explore different paths of the program by continuously creating inputs, and determine whether these paths will cause problems that cause software crashes or downtime. The most widely us...
