Abstract

An embodiment of the present invention provides a method and device for mining industrial control vulnerabilities, the method comprising: obtaining a typical message list based on a set of data packets to be analyzed; obtaining a seed list based on the typical message list; obtaining a malformed data packet based on the seed list; Vulnerabilities mining and verification are performed on the target device based on the malformed data packets. Through the similarity comparison of the reply messages, high-quality seeds are selected to mutate and generate malformed data packets, and then remote fuzzy testing is carried out to achieve the purpose of effectively discovering security defects in the Internet of Things and industrial control system equipment, and improve the security of industrial control systems. Effectiveness of vulnerability mining in devices.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method and device for mining industrial control loopholes. Background technique [0002] In recent years, various network attacks against the Internet of Things and industrial control system equipment have been increasing, and the security problems in the Internet of Things and industrial control system equipment have become more and more serious. Pre-discovering and repairing security vulnerabilities in IoT embedded devices and industrial control systems can effectively prevent security threats and improve the security protection level of industrial control systems. [0003] Due to the characteristics of Internet of Things devices and industrial control system devices that are closed, difficult to debug, high real-time, and difficult to simulate, traditional vulnerability mining methods, such as reverse analysis, symbolic execution, and taint tracking, are difficult t...
