序列模式挖掘在入侵检测中的应用研究

入侵检测系统是计算机安全体系中的一个重要构成要素,随着网络数据流量的不断增大,与数据挖掘相结合的入侵检测系统成为了研究热点。本文针对计算机入侵检测中网络安全审计数据的特点,提出了一个改进的PrefixSpan算法,并通过检测一个网络审计记录的实验,进行了结果分析。

Research on Sequential Pattern Mining in Intrusion Detection System

The Intrusion Detection System(IDS,Intrusion Detection System) is an important component of the computer security architecture.With the increasing data flow of network,the intrusion detection system that is combined with the data mining has become a research hotspot.An improved PrefixSpan algorithm based on time constraints and attribute-relative is developed to fit into the network audit data of computer intrusion detection.The experiment of dealing with a computer network audit database gives the application and result analysis of the algorithm.
