Abstract: Pattern matching is the core module in network security system, it’s the highest occupancy rate of system resources is more than 70%. According to problem and challenges of pattern matching in the network security system, taking 2000 as the boundary, the pattern matching was divided into the traditional pattern matching method and the new pattern matching method. Through the analysis of the principle and the computational complexity of different pattern matching method and the development and evolution of the new pattern matching method, applicable environment of different methods was concluded. A comprehensive review and evaluation of pattern matching in network security system was presented. Finally, a conclusion and some suggestions for future research were summarized and prospected.
