Intrusion Detection Method Based on Denoising Autoencoder and Three-way Decisions

Intrusion detection plays a vital role in computer network security.Intrusion detection is one of the key technologies of network security and needs to be kept under constant attention.As the network environment becomes more and more complex,network intrusion behaviors gradually show diversified and intelligent characteristics,and network intrusion is also becoming more difficult to detect.And the research conducted in the field of network security is also an endless study.For the above reasons,people are worried about the feasibility and sustainability of the current method,specifically,it is difficult for current intrusion detection methods to perfectly abstract the features contained in intrusion behaviors,and most of the current intrusion detection methods perform poorly on unknown attacks.In response to these problems,we propose an intrusion detection method DAE-3WD based on denoising autoencoder and three-way decisions.We hope that our method can effectively promote the research on intrusion detection.T
