Which of the following risks can be mitigated by HTTP headers?

SQL injection (SQLi) attacks exploit vulnerabilities in the database layer of an application, allowing attackers to manipulate SQL queries. While HTTP headers can enhance security practices, they do not directly mitigate SQLi risks, which require input validation and parameterized queries to safeguard against such threats.

Denial of Service (DoS) attacks aim to overwhelm a server or network, rendering services unavailable to legitimate users. Mitigation strategies for DoS attacks typically involve network-level defenses and resource management rather than HTTP headers, which do not directly address the nature of such attacks.

Secure Sockets Layer (SSL) is a protocol for encrypting data in transit, ensuring secure communication between clients and servers. While SSL enhances security, it is not a risk that can be mitigated by HTTP headers; instead, it relies on proper certificate implementation and configuration to protect against eavesdropping and man-in-the-middle attacks.
