Website Hacking using SQL Injection Method and its Prevention

Abstract

SQL injection is a popular and frequently used attack on websites, which attackers use to steal large volumes of (client) information. Although there are other types of attacks for capturing this information, SQL injection appears to be a frequently used method.A website becomes vulnerable to SQL injection when attackers are able to influence the queries sent by a website to a database. This enables the attacker to extract information from the database or to change the contents of the database through, for example, a simple query. In this way, an SQL injection vulnerability can endanger both the integrity as well as the confidentiality of the information behind the website.
