Securing SQL Injection flaw

SQL injection flaw is predominant in last few years of network security. By exploiting the input validation, the attacker can inject the SQL injection query from the front end to explore the back end data stored in the database. Securing of data from the attacker who involved in injection flaw is becoming more challenging. We proposed an approach to detect the injection attack query and retrieving back the access control from where it last. We are utilizing pattern matching technique and token management technique. KMP (Knuth Morris Pratt) pattern searching algorithm is used for validation of input queries and token management technique is used to retrieve back the access control from where it last. Since provision of both prevention and recovery process makes the system more secure than the existing one.
