摘要:

入侵检测系统经常不可避免地出现误警、漏警错误而导致系统的重大安全隐患,然而当前未能找到一种行之有效的解决方案。针对该问题,提出一种基于信息论的入侵检测最佳响应模型。首先,将入侵检测过程中的入侵者和入侵检测系统抽象成随机变量,并根据对抗结果构建了入侵者和入侵检测系统的攻防模型。其次,根据攻防模型设计入侵检测系统的防守信道,将入侵检测系统的正确检测转换成防守信道成功传输1 bit信息问题。最后,通过分析防守信道的信道容量来衡量系统防守能力,其防守信道的最大互信息量就是入侵检测系统的防守极限能力,其对应的策略分布就是系统的防守能力最佳响应策略。实验结果表明,所提方案能够有效地降低系统误警和漏警所造成损失。

Abstract:

Intrusion detection system (IDS) often inevitably presents major security risks caused by FPs and FNs.However,at present,an effective solution has not been found.In order to solve this problem,an optimal response model of intrusion detection based on information theory was proposed.Firstly,the intruder and IDS in the process of intrusion detection were abstracted into random variables,and the attack and defense model of intruder and IDS was constructed according to the results of the confrontation.Secondly,the defense channel of IDS was designed according to the attack and defense model,then the correct detection of IDS was transformed into the problem of successful transmission of 1 bit information in defensive channel.Finally,the defensive capability of the system was measured by analyzing the channel capacity of the defensive channel,the maximum mutual information of the defensive channel was the defensive limit capability of the IDS,and the corresponding strategy distribution was the optimal response strategy of the defensive capability of the system.The experimental results show that the scheme can effectively reduce the loss caused by FPs and FNs.

Key words: intrusion detection system, average mutual information, channel capacity, detection rate, response scheme
