Research on Active Defence Technology with Host Intrusion Based on K-Nearest Neighbor Algorithm of Kernel

Abstract

In this paper, the intrusion detection system is introduced, and point out two important prerequisite that the IDS work normally must depend on, and in view of the prerequisite, the paper proposed a solution which is based on k-nearest neighbor algorithm of kernel and the active defence technology anti-host intrusion. The solution can distinguish normal event from the unknown event efficiently, and can detect unknown event more accurately.
