Abstract:

To solve the problems in intrusion detection based on pattern matching, we present a packet detection method based on negative pattern,which uses the negative pattern matching strategy.Firstly,the method detects the NP pattern in the to-be-detected packets and divides the data into segments according to NP pattern.Secondly,the system detects the data segments by NP pattern.The experimental results show that the method can reduce the false alarm rate and improve the detection efficiency of the system.

Key words: negative Pattern, pattern match, intrusion detection, network security
