AC-BM-GA Pattern Matching Algorithm Approach for Intrusion Detection

In network security, Intrusion Detection System plays a reasonable supplementary role for the firewall. It improves the security and reliability of the computer and helps protect computers from network attacks. At present intrusion detection system analysis module uses the pattern matching technology. In this article, through analyzing the advantages and disadvantages of the main pattern matching algorithm of current Intrusion Detection System an optimized algorithm was proposed. And through simulation experiments, it also proved that the optimized algorithm has better matching efficiency than the original algorithm. So if this algorithm is applied to the intrusion detection the performance of the system can be improved. Keywords— Intrusion Detection System (IDS), Pattern Matching Algorithm.
