Preventing SQL Injection Attacks
With the recent rapid increase in web based applications that employ back-end database services, results show that SQL Injection and Remote File Inclusion are the two frequently used exploits rather than using other complicated techniques. With the rise in use of web applications, SQL injection based attacks are gradually increasing and is now one of the most common attacks in the internet. It ...
متن کاملSQLrand: Preventing SQL Injection Attacks
We present a practical protection mechanism against SQL injection attacks. Such attacks target databases that are accessible through a web frontend, and take advantage of flaws in the input validation logic of Web components such as CGI scripts. We apply the concept of instruction-set randomization to SQL, creating instances of the language that are unpredictable to the attacker. Queries inject...
متن کاملFont Level Tainting: Another Approach for Preventing SQL Injection Attacks
the font level tainting is the another new approach for preventing sql injection attacks, that involves comparing the meta strings library with the sql statements that includes the characters including the different font levels in the user input, to prevent them if found any and protecting the web applications against sql injection is discussed in this paper. this paper includes the strange ide...
متن کاملInferential SQL Injection Attacks
This paper describes a class of SQL injection attacks (SQLIA) where attackers can deduce information from the back-end database management system (DBMS) without transferring actual data. Instead, by using predetermined differentiation mechanism, information is being inferred piece by piece. Because of its widespread success, particularly in difficult situations where other SQLIA classes fail, u...
متن کاملMethods of Identifying and Preventing SQL Attacks
The paper begins by identifying the organizations which are vulnerable to the SQL attack referred to as an SQL injection attack (SQLIA). The term “SQL injection attack” is defined and a diagram (Fig.1) is used to illustrate the way that attack occurs. In another section, the paper identifies the methods used to detect an attack to SQL, whereby the techniques are discussed extensively using rele...
