A novel method for SQL injection attack detection based on removing SQL query attribute values

Detection and Prevention of SQL Injection attack

SQL injection is a technique where the attacker injects an input in the query in order to change the structure of the query intended by the programmer and gaining the access of the database which results modification or deletion of the user’s data. In the injection it exploits a security vulnerability occurring in database layer of an application. SQL injection attack is the most common attack ...

An Approach to Detection of SQL Injection Attack Based on Dynamic Query Matching

A large number of web applications, especially those deployed by companies for e-business operations involve high reliability, efficiency and confidentiality. Such applications are often written in script languages like PHP embedded in HTML, allowing establishing connection to databases, retrieving data, and putting them in the Web. One of the most common in web application attacks is SQL Injec...

Data-mining based SQL injection attack detection using internal query trees

Detecting SQL injection attacks (SQLIAs) is becoming increasingly important in database-driven web sites. Until now, most of the studies on SQLIA detection have focused on the structured query language (SQL) structure at the application level. Unfortunately, this approach inevitably fails to detect those attacks that use already stored procedure and data within the database system. In this pape...

SQL Injection Evasion Detection

Testing for Tautology based SQL Injection Attack using Runtime Monitors

Today, all commercial and business applications (ecommerce, banking, blogs, web mail, etc.,) are built as webbased database applications. Increasing prominence and usage of these applications has made them more susceptible to attacks because they store huge amount of sensitive user information. Traditional security mechanisms like network firewalls, intrusion detection systems, and use of encry...
