在目前基于Agent 的分布式入侵检测系统的设计中，主要的设计思路是依赖多Agent 联盟合作机制，但在具体的工程实现中，却难以找到一种恰当的实现模型。本文针对此问题，提出了基于有色Petri Net 的多Agent 入侵检测系统实现模型。关键词：有色Petri Net；多Agent；入侵检测系统Abstract: Nowadays,the main method in design of the distributed intrusion detectionsystem based on multi agent depends on multi agent cooperative mechanism,but we can hardly find a model of implementation.In this paper,we offer a new model about the implementation of multi agent intrusion detection system based on Colored Petri Net..Key words: Colored Petri Net; multi agent; Intrusion detection system
