Research on Distributed Intrusion Detection System Based on Mobile Agent

For the problems of traditional intrusion detection system, a distributed intrusion detection system based on mobile agent was designed. In this paper, the internal function of mobile agent was divided in architecture view, and the optimal agent migration algorithm was researched to facilitate the agent collaborative processing. The communication manner and interactive processes were applied in the design. Furthermore, the traditional Boyer-Moore (BM) algorithm was improved. The simulation results showed that the system could reduce the network load, shorten the waiting time of network. All these contributed on the improvement of the intrusion detection. Then, the dynamic adaption of the system could be implemented while false alarm rate and false negative rate would be reduced. Therefore, the system is suitable for large-scale heterogeneous network.
