摘要
网络入侵检测系统常常依赖于精确的模式匹配技术 ,依赖于算法的选择、实现以及使用频率。这种模式匹配技术可能成为入侵检测系统的瓶颈 ,为了跟上快速增长的网络速度和网络流量 ,Snort(开放源代码的网络入侵检测系统 )中采用了快速多模式匹配算法 。
Network Intrusion Detection Systems(NIDS)often rely on exact pattern matching techniques.Depending on the choice of algorithm,implementation and the frequency with which it is applied,this pattern matching may become a performan ce bottleneck.To keep up with increasing network speeds and traffic,Snort takes advantage of advanced string matching algorithms.In this paper,it is described t hat a faster multi-pattern matching algorithm and its effectiveness.
