Neutralizing SQL injection attack using server side code modification in web applications

Abstract

Reports on web application security risks show that SQL injection is the top most vulnerability. The journey of static to dynamic web pages leads to the use of database in web applications. Due to the lack of secure coding techniques, SQL injection vulnerability prevails in a large set ofweb applications.Asuccessful SQL injection attack imposes a serious threat to the database,web application, and the entire web server. In this article, the authors have proposed a novel method for prevention of SQL injection attack. The classification of SQL injection attacks has been done based on themethods used to exploit this vulnerability.The proposedmethod proves to be efficient in the context of its ability to prevent all types of SQL injection attacks. Some popular SQL injection attack tools and web application security datasets have been used to validate the model.The results obtained are promising with a high accuracy rate for detection of SQL injection attack.
