SQLI detection system for a safer web application

SQL Injection (SQLI) is a quotidian phenomenon in the field of network security. It is a potent and effective way of intruding into secured databases thereby jeopardizing the confidentiality, integrity and availability of information in them. SQL Injection works by inserting malicious queries into legal queries thereby rendering it increasingly arduous for most detection systems to be able to discern its occurrence. Hence, the need of the hour is to build a coherent and a smart SQL Injection detection system to make web applications safer and thus, more reliable. Unlike a great majority of current detection tools and systems that are deployed at a region between the web server and the database server, the proposed system is deployed between client and the web server, thereby shielding the web server from the inimical impacts of the attack. This approach is nascent and efficient in terms of detection, ranking and notification of the attack designed using pattern matching algorithm based on the concept of hashing.
