摘要
提出了一种基于正则语言描述的网络状态入侵行为方法。该方法结合网络入侵的目标和特点,利用有穷自动机理论,基于网络协议来实现进程和操作系统的状态建立,从而可以发现未知的入侵。论证了应用该方法的可行性,利用通用入侵检测框架CIDF对应用这种方法的入侵检测系统进行了描述,并讨论了该系统实现时攻击描述的判断和存储方式,最后与其它入侵行为方法进行了比较。
First, a network state intrusion action method based positive language describing was presented. This method is established by using DFA theory, characters and goals of net-attacks and fully depending on states of the processes of net protocols and operation system, so it could discover unknown attacks. It was proved that the method was feasible for intrusion detection and described IDS that using this model to describe net-attacks by CIDF （Common Intrusion Detection Framework）. Then the method＇s storage and implement were discussed. In the end, the method was compared with other intrusion detection descriptions.
