Which method is NOT effective in preventing server-side request forgery (SSRF) attacks?

Server-Side Request Forgery (SSRF) attacks exploit the vulnerabilities of a server by allowing an attacker to send crafted requests to unintended destinations. When evaluating the methods to mitigate these attacks, it is clear that removing SQL code from submitted HTTP queries does not directly address the root of SSRF vulnerabilities.

While SQL injection is a different type of attack that manipulates database queries, SSRF primarily concerns itself with how the server processes outbound connections based on input it receives. Therefore, simply removing SQL code does not prevent SSRF because the attack does not inherently rely on SQL injection techniques. Instead, SSRF focuses on how requests are crafted and sent from the server, often targeting internal resources or services.

In contrast, implementing strict input validation ensures that only expected and legitimate requests are processed. Restricting outbound connections limits the server's capacity to initiate requests to external or internal systems, thereby reducing the attack surface for potential SSRF exploits. Finally, logging and monitoring requests help in identifying and responding to anomalous behavior that might suggest an ongoing SSRF attack or other vulnerabilities being exploited.

Thus, the method that does not effectively prevent SSRF attacks is the removal of SQL code from submitted HTTP queries, as it does not address the mechanics of how these
