Abstract

Embodiments of the invention provide an industrial control vulnerability mining method and device. The method comprises the steps of obtaining a typical message list based on a to-be-analyzed data packet set; acquiring a seed list based on the typical message list; obtaining an abnormal data packet based on the seed list; and performing vulnerability mining and verification on the target device based on the malformed data packet. Through similarity comparison of reply messages, high-quality seeds are selected for variation to generate a malformed data packet, and then remote fuzzy testing is performed, so that the purpose of effectively discovering security defects existing in the Internet of Things and industrial control system equipment is achieved, and the effectiveness of vulnerabilitymining in the industrial control system equipment is improved.

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...
