Guarding web application with multi - Angled attack detection

An important research issue in the design of web application is protecting the front end web application from unauthorized access. Normally the web application is in the front end and database is in the back end and can be accessible using web browser. The database contains valuable information and it is the target for the attackers. There are many security issues in the back end database and many security measures being implemented in order to protect it. The problem here is, the front end application has set accessible by everyone and the attackers are trying to compromise the web front end application which in turn compromise the back end database. Therefore, the challenge here is to provide security to the front end web application thus enhancing security to the back end database. Currently vulnerability scanner is used to provide security to the front end web application. Even though many attacks are possible with it the most common and top most attacks are “Remote file inclusion attack, Query string attack, Union attack, Cross site scripting attack”. The proposed system is based on the design of web application in which it concentrates mainly on the detection and prevention of above said attacks. Initially, the system will show how these attacks are happening in the front end web application and overcoming of these attacks using the proposed algorithms such as longest common subsequence algorithm and brute force string matching algorithm. The successful overcoming of these attacks enhances security in the back end by implementing security in the web front end.
