Concurrent fuzzing method and device for network equipment based on mutation strategy

Abstract

This application provides a method and device for concurrent fuzzing testing of network equipment based on a mutation strategy. In this embodiment, by converting the normal data packet into a mutation request packet for fuzz testing the target network device, and sending N different mutation request packets to the target network device concurrently, at least one response packet received carries the target If the content of the network device is abnormal, or if the abnormality of the target network device is currently detected, the concurrent mutation request packet will be suspended, and if the target network device is detected to return from abnormality to normal, the concurrent mutation request packet will be suspended in a serial manner The at least one mutation request packet that has been sent is resent to the target network device to determine the mutation request packet that makes the target network device abnormal, and eliminate the security loopholes in the target network device based on the determined mutation request packet, which realizes Automated mutation policy-based concurrent fuzzing of network devices.

Description

technical field [0001] This application relates to data security technology, in particular to a method and device for concurrent fuzzing testing of network equipment based on mutation strategies. Background technique [0002] In the application of network devices, due to the complexity and variety of applications, each application will be compiled with a corresponding basic code version at the beginning. However, as the demand for applications continues to increase, each application will evolve into different customized versions. Based on this, the requirements for the reliability and security of applications in network equipment are very high. At present, network equipment is often checked manually, which requires a large workload and low efficiency. Contents of the invention [0003] Embodiments of the present application provide a method and device for concurrent fuzzing testing of network equipment based on mutation strategies, so as to realize automatic concurrent fu...
