The SQL Injection and Signature Evasion

SQL Injection Evasion Detection

On the Property of the Distribution of Symbols in SQL Injection Attack

SQL injection is an attack of type to insert malicious query via an input form on web site. If SQL injection attack were successful, there are the threats of unauthorized access, information leak or falsification of data for web applications driven database system. In the conventional studies, a lot of prevention and detection methods using pattern matching, parsing or machine learning have bee...

SQLPrevent: Effective Dynamic Detection and Prevention of SQL Injection Attacks Without Access to the Application Source Code

This paper presents an effective approach for detecting and preventing known as well as novel SQL injection attacks. Unlike existing approaches, ours (1) is resistant to evasion techniques, such as hexadecimal encoding or inline comment, (2) does not require analysis or modification of the application source code, (3) does not need training traces, (4) does not require modification of the runti...

An Automatic Detection System for SQL Injection

The growth of the internet is increasing day by day, mostly content is database driven. There are many web applications like E-Commerce, banking where he/she has to trust on this application and have to provide personal information into their underlying database. If there is no confidentiality and security of information then any one can steal or see our information or may utilize this informat...

SQLPrevent: Effective dynamic detection and prevention of SQL injection

This paper presents an approach for retrofitting existing web applications with run-time protection against known as well as unseen SQL injection attacks (SQLIAs). This approach (1) is resistant to evasion techniques, such as hexadecimal encoding or inline comment, (2) does not require analysis or modification of the application source code, (3) does not require modification of the runtime envi...
