Whenever web-application executes dynamic SQL statements it may come under SQL injection attack. To evaluate the existing practices of its detection, we con- sider two different security scenarios for the web-application authentication that generates dynamic SQL query with the user input data. Accordingly, we generate two different datasets by considering all possible vulnerabilities in the run-time queries. We present proposed approach based on edit-distance to classify a dynamic SQL query as normal or malicious using web-profile prepared with the dynamic SQL queries during training phase. We evaluate the dataset using proposed approach and some well-known supervised clas- sification approaches. Our proposed method is found more effective in detecting SQL injection attack under both the scenarios of authentication security.
