分布式入侵檢測系統有許多優點，如可測量性和抗破壞性。然而，在具體實施過程
中存在著許多障礙。移動代理（MA）技術有著適合分布式入侵檢測系統具體實施的許多特性。基于移動代理的分布式入侵檢測系統利用移動代理技術同等地處理來自每臺被監視主機的信息，然后完成對入侵行為的全局信息提取。本文深入分析了一種基于移動代理的分布式入侵檢測系統。

Research on a Mobile Agent-based Distributed Intrusion Detection System Wang Xia Chen Yunzhi College of Information Science and Engineering,Nanjing University of Technology,Jiangsu,Nanjing, 210009 Abstract：Distributed intrusion detection systems (DIDS) have many advantages such? as scalability, subversion resistance. However, there are some impediments when they are implemented. The mobile agent (MA) technology is of many features to suit the implementation of distributed IDS. MADIDS employs MA technology to coordinately process information from each monitored host, and then completes global information extraction of intruder actions. A MADIDA is analyzed thoroughly in this paper.
