Design and Realization of Distributed Intrusion Detection System Based on Ring Structure

Through analyzing the characteristics and the cooperating mode of the present distributed intrusion detection system, this paper proposes a kind of Distributed Intrusion Detection System(DIDS) model based on annular structure and Token Ring mechanism. This paper expatiates on the architecture and function framework of the DIDS, introduces the idea of priority reaction and event reliability, gives the algorithm of distributed intrusion detection cooperating and overcomes the defects such as complicated structure and load imbalance in each subsystem of the present distributed intrusion detection system.
