摘要: 降低虚警率是异常入侵检测系统(AIDS)的一个主要目标。分析了AIDS虚警率问题产生的主要原因,提出了一种基于人工免疫思想,动态构建正常系统轮廓,抑制虚警率的方法。给出了生物免疫系统与AIDS的映射关系,建立了自体动态描述、抗体的动态演化和淘汰机制,并进行了仿真和对比实验。理论分析和实验结果表明该方法可有效降低系统虚警率。

Abstract: The false positive rate of Anomaly Intrusion Detection System(AIDS) is analyzed.Methods to reduce the false positive rate are presented after analyzing creditability of IDS and false positive rate of anomaly IDS.The emphasis of this paper is to construct normal profile dynamically based on artificial immunity to restrain false positive rate,and simulation experiment is done.The results show that the method can improve the detection efficiency and reduce the false positive rate.

Key words: Anomaly Intrusion Detection System(AIDS), false positive rate, artificial immunity
