An Improved Intrusion Detection System Based on Agent

This paper firstly analyzes the necessity of Intrusion Detection System for computer network, and then it proposes an improved intrusion detection system based on Agent by introducing the STAT (State Transition Analysis Tool). The improved system updates rules by Agents, and it perceives real-timely the state of the intruding activities and analyzes them by STAT. It is indicated from the experimental result that the improved intrusion detection system based on Agent is capable of increasing efficiently the detection rate. Finally, the present thesis analyzes the application of this system with its characters.
