Which term refers to the methods used to exploit vulnerabilities?

The correct term that refers to the methods used to exploit vulnerabilities is "Threat vector." A threat vector is a path or means by which a threat actor can gain access to a system or network in order to deliver a payload or access sensitive data. This could include various methods such as malware, phishing, social engineering, or exploiting unpatched software vulnerabilities.

Understanding threat vectors is crucial in cybersecurity as it helps organizations identify and prioritize their defenses against potential attacks. By knowing the possible avenues that attackers might use to infiltrate systems, security measures can be designed and implemented to mitigate these risks effectively.

In contrast, a threat agent refers to the individual or group that poses a threat, while a threat event describes the occurrence of an attack or breach. Threat assessment is the process of analyzing and evaluating potential risks and vulnerabilities, rather than focusing on the methods themselves.
