Abstract: Today, web applications have become a ubiquitous use of daily tasks, such as banking, travel, and social networking, etc., Due to their ubiquitous use for daily tasks, web applications have always been the target of attacks. In the existing system, communication between the web server and the database server is not separated, and can hardly understand the relationships among them. We propose an efficient IDS system as Double Guard with lightweight virtualization that models the network behavior for multi-tiered web applications of user sessions and able to identify ferret out attacks. Casual Mapping profile model is newly developed to map between the web server requests and the subsequent DB queries, identifies the various types of attacks and minimize the false positives for both static and dynamic web application.
