How do you identify and prevent SQL injection attacks, detailing the vulnerabilities involved?

SQL injection attacks are identified and prevented by addressing the vulnerabilities that allow them to occur. The primary vulnerability is insufficient input validation and sanitization of user-supplied data used in SQL queries. This allows attackers to inject malicious SQL code into the query, which can then be executed by the database server. Identification involves several methods. Code reviews can identify areas where user input is directly incorporated into SQL queries without proper sanitization. Web application firewalls (WAFs) can be configured to detect and block SQL i....
