Abstract

With the rise of the Internet, web applications, such as online banking and web-based email, have become integral to many people's daily lives. Web applications have brought with them new classes of computer security vulnerabilities, such as SQL injection. It is a class of input validation based vulnerabilities. Typical uses of SQL injection leak confidential information from a database, by-pass authentication logic, or add unauthorized accounts to a database. This security prevents the unauthorized access to your database and also it prevents your data from being altered or deleted by users without the appropriate permissions. Malicious Text Detector, Constraint Validation, Query length validation and Text based Key Generator are the four types of filtration technique used to detect and prevent the SQL Injection Attacks from accessing the database
