Abstract

The invention provides an equipment protocol vulnerability detection method and device, and the method comprises the steps: determining a to-be-detected protocol type of to-be-detected equipment, and obtaining a protocol message corresponding to the to-be-detected protocol type in a system where the to-be-detected equipment is located; obtaining a relationship between fields in the protocol message; performing protocol state machine learning on a system where the to-be-detected equipment is located according to the protocol message, and obtaining a state machine path of the system where the to-be-detected equipment is located; determining a test case generation method according to the state paths, and generating test cases corresponding to the state paths according to the test case generation method in combination with the relationship between the fields; and inputting the test case into the to-be-detected equipment, and obtaining a protocol vulnerability detection result of the to-be-detected equipment according to the working state of the to-be-detected equipment. According to the method and the device, the test cases are generated in combination with the relationship among the fields in the protocol message and the state path, so that a large number of redundant test cases are prevented from being generated, the code coverage rate is improved, and the vulnerability detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a device protocol vulnerability detection method and device. Background technique [0002] After the application of industrial automation control technology and Internet of Things technology, the power system has gained efficiency and benefits, but it is also facing serious security threats. There may be loopholes in the power equipment protocol. Using such loopholes to attack downstream equipment such as smart meters in the power system may break through the protection measures of the power system, affect the backbone network of the power system, and cause a wider range of failures. Therefore, it is extremely necessary for the security protection of the power system to discover the current downstream equipment protocol and system loopholes in the power system. [0003] The application of traditional fuzz testing technology can detect program vulnerabilities in the equi...
