Study on the Pattern Matching Technology and Its Application in Network Security

In this paper, we concentrate on the problem of network security protection, and we proposed a novel pattern matching algorithm to tackle this problem. Particularly, we focus on the problem SQL Injection, which is a typical network security problem, and it means a type of web application security vulnerability. Afterwards, a typical pattern matching based network security system is illustrated. Additionally, we define that a pattern is a set of specific ternary strings in the traffic which illustrates the probability of potential intrusion or abnormality of the network. Furthermore, a novel pattern matching algorithm is given. In the end, to demonstrate the effectiveness of our method, experiments are conducted to maker performance.
