Combinatorial Approach for Preventing SQL
Injection Attacks
A combinatorial approach for protecting Web applications against SQL injection is discussed in this page. The the attackers get unrestricted access to the database that underlie Web applications. detection mode for SQL injection using pair wise sequence alignment of amino acid code formulated from web application form parameter sent via web server is required from the signature based detection point of view. The analysis of the transaction to find out the malicious code is favourable from Auditing based method standpoint. Hirschberg algorithm is used for the method. This is a approach using divide and conquer to reduce the time and space complexity.
INTRODUCTION
SQL injection attack involves placing SQL statements in the user input for corrupting or accessing the Database. Firewall, cryptography and traditional Intrusion detection can all be easily bypassed by the SQL injection attacks. ASP, ASP.NET, PHP, JSP, CGI and other dynamic script languages are vulnerable to SQL injection attacks. ItIt affects the database without the knowledge of the database administrator. The cross site scripting attacks, SQL Injections attacks and Buffer Overflow are the major threat in the web application security system in terms of input validation security issues. 20 percent of the input validation issues are SQL Injection vulnerabilities (SQLIVS).
defense coding maybe a suggestion but it isn't efficient due to difficulty in bringing about a rigorous defensive coding principle and that only a a subset of the possible attacks can be solved.
