Abstract: This paper researches on the currently common in pattern matching algorithm in network intrusion detection system, carrying out a detailed analysis and comparison of the pattern matching algorithm for famous Snort system. Based on the existed algorithm as BMH, the paper proposes an improved algorithm, seeking optimal effects. The improved BMH pattern matching algorithm in network intrusion detection system is applied to the real network intrusion detection, and the results get scientifically evaluated. Through the practical application, the effectiveness and feasibility of the improved algorithm is shown again.
Key words: network intrusion detection system, pattern matching, single-pattern, optimized strategies
