A real-time rule-matching algorithm for the network security audit system

Combined with the characteristics of network security audit system, paper introduced the idea of dynamic programming to pattern-matching algorithm, and gave the best dynamic matching algorithm, that is, by solving for matching pairs of local sub-problem, and for the number of different rules, (deleted) to find the best combination for the pattern-matching algorithms, then to achieve the strategy of optimal solution overall. Experimental results show that, the algorithm will greatly improve the efficiency of pattern matching in the network security auditing system.
