SQL injection attack is widely used by attackers to gain unauthorized access to systems. This software system is developed to prevent unauthorized access to system using SQL injection attacks. This is done by adding unique value and a signature based authentication technique to verify authenticity. SQL injection is a major security issue these days that allows an attacker to gain access of a web system or application exploiting certain vulnerabilities. This method exploits various web application parameters such as transmitting the traveling form data parameters with an efficient integration of amino acid codes aligned in it. In other words, this software project puts forth a method to analyze and detect the malicious code to find out and prevent the attack. It uses an alternative algorithm for signature based scanning method; this method is based on a different divide and conquers strategy that detects attacks based on various time/space parameters. This innovative system has proved successful in preventing various SQL injection attacks based on its efficient attack detection strategies.
What is SQL Injection?
SQL injection is a type of security exploit in which the attacker adds Structured Query Language (SQL) code to a Web form input box to gain access to resources or make changes to data. An SQL query is a request for some action to be performed on a database. Typically, on a Web form for user authentication, when a user enters their name and password into the text boxes provided for them, those values are inserted into a SELECT query. If the values entered are found as expected, the user is allowed access; if they aren’t found, access is denied.
However, most Web forms have no mechanisms in place to block input other than names and passwords. Unless such precautions are taken, an attacker can use the input boxes to send their own request to the database, which could allow them to download the entire database or interact with it in other illicit ways.

- Detects malicious code when anyone tries to input using SQL Injection.
- Signature based authentication technique to verify authenticity is used.
