Research and development of intrusion detection technology

Intrusion detection technology is an active defensive security technology. It is an important part of the network security system. It can make up for the lack of traditional security technology. In this paper, we has all-round systematically elaborate on the intrusion detection technology in the multiple aspects at the concept, function, method, principle. As the result, the research of the intrusion detection technology will become the hot spot in the field of network security. In this paper, it provides a technical and theoretical basis for the further research of intrusion detection technologies.
