Reverse proxy framework using sanitization technique for intrusion prevention in database

Abstract

With the increasing importance of the internet in our day-to-day life, data security in web application has become very crucial. Ever increasing online and real time transaction services have led to manifold rise in the problems associated with the database security. Attacker uses illegal and unauthorized approaches to hijack the confidential information like username, password and other vital details. Hence the real-time transaction requires security against web based attacks. SQL injection and cross site scripting attack are the most common application layer attack. The SQL injection attacker pass SQL statement through a web application's input fields, URL or hidden parameters and get access to the database or update it. The attacker take a benefit from user provided data in such a way that the user's input is handled as a SQL code. Using this vulnerability an attacker can execute SQL commands directly on the database. SQL injection attacks are most serious threats which take user's input and integrate it into SQL query. Reverse Proxy is a technique which is used to sanitize the users' inputs that may transform into a database attack. In this technique a data redirector program redirects the user's input to the proxy server before it is sent to the application server. At the proxy server, data cleaning algorithm is triggered using a sanitizing application. In this framework we include detection and sanitization of the tainted information being sent to the database and innovate a new prototype.
