These days' cyber attacks have become a major concern because these attackers can steal important documents and damage websites and access confidential information and may drive many corporations that conduct their business through the web to suffer financial and reputation damages. Out of all those attacks the most dangerous cyber attack is the Structured Query Language (SQL)-injection attack. This type of attack can be easily made via normal web browsers that users use for surfing the net in their day to day life. A characteristic diagnostic feature of SQL injection attacks is that they change the intended structure of queries issued. Most web application developers do not apply user input validation and they are not aware about the consequences of such practices.
