Detection and Prevention of SQL-Injection Attacks of Web Application Using Comparing the Length of SQL Query Length
Now-a-days, the authors are using the web applications, but the application code is not secured so there is existence of the SQL injection attacks. In web applications with the help of the internet explorer the user tries to access the information. But most of the web applications are affected by the SQL-injection attacks. The authors' main aim of the research is to find the method which is able to detect and prevent the web applications from the SQL Injection attacks. In their approach firstly, they check the length of the original SQL Query and store its length value. If there is another Query which is used for SQL-Injection attacks, then they too check the length of this SQL Query and store its value.
