Research on Multi-pattem Matching Algorithm of Computer Network Intrusion Detection System

In order to be able to effectively guarantee network security and improve the performance and efficiency of computer network intrusion detection, the research on the matching algorithm of computer network intrusion detection system is realized. First, the paper conducts a comprehensive analysis of the algorithm and principle of network intrusion detection. Next, it continues to construct the basic model of computer network intrusion detection, and propose a computer network intrusion detection system multi-pattern matching algorithm. Then, the paper carries out the multi-pattern matching algorithm of the computer network intrusion detection system Analyze, and designs a computer network intrusion detection system based on multi-pattern matching algorithm, and improves the multi-pattern matching algorithm to increase the efficiency of the pattern matching algorithm. Finally, the paper compares conventional matching algorithms to get an algorithm that meets the needs of computer network intrusion detection systems. The test results show that the optimized multi-pattern matching algorithm can improve the detection performance of the network detection system and has a certain practicability.
