摘要
在分析以往入侵检测系统的基础上,介绍了一个误用检测与异常检测相结合的基于用户行为的多层自适应入侵检测系统模型。给出了模型的框架图以及模型主要的流程步骤,并详细分析了遗传算法在模型中的应用,给出了编码策略、适应度函数及遗传操作。
This paper proposes a multilayered adaptive intrusion detection model based on user＇s behavior, the model of which integrates the working of misuse with anomaly detector. The frame structure and the flow chart are also given in this paper and the genetic algorithm is applied in this model. The coding policy, fitness function and genetic operation are given and analyzed.
