SQL INJECTION DETECTION AND PREVENTION USING HYBRID APPROACH

Web applications such as blogs, social network, webmail, bank etc have become our way of life. Among the top ten web application vulnerabilities published by Open Web Application Security Project, SQL Injection Attack (SQLIA) is the most vulnerable. An SQLIA occurs when an attacker changes the intended effect of an SQL query by inserting (or injecting) new SQL keywords or operators into the query thereby gaining unauthorized access to a database in order to view or manipulate restricted data. In proposed work, a new hybrid approach is developed to detect and prevent the sql injection attack in sql queries. Proposed system is tested using various queries given by various users and results are evaluated very accurate.
