CFAR Intrusion Detection Method Based On ARMA Model

With the popularization of the applications of network-based computer systems and the increasing of e-commerce, security issues become more and more outstanding. There are increasing amount of attacks year after year, with more increasing rate in the recent years. These security accidents result in tremendous damages to our society. Intrusion prevention techniques, such as user authentication, network firewall, and information protection have been used to protect computer systems as a first line of defense. Intrusion prevention alone is not sufficient. For example, they cannot avoid attacks inside. Intrusion detection is therefore needed as another wall to protect computer systems. As a serious technique in computer security, intrusion detection has been paid more attention gradually. However, current intrusion detection systems lack effectiveness, adaptability and extensibility, and especially, they become ineffective in the face of new kinds of attacks. Aimed...
