Method of defense SQL injection attacks based on sequence alignment
基于序列比对的SQL注入攻击检测方法*

SQL injection attacks pose a serious threat to the security of Web applications because they can give attackers unrestricted access to databases that contain sensitive information. This paper proposed a new method based on sequence alignment for protecting existing Web applications against SQL injection. Elaborated implementation and detection pattern with sequence alignment algorithm in detail. Finally analyzed and tested the correctness and performance of the method. Experimental results show that this method is simple and effective.
