What is a threat vector?

A threat vector refers to the specific method or pathway that threat actors exploit to compromise a system or network. It encompasses the various means through which a threat can enter a system, whether through software vulnerabilities, phishing attacks, malicious links, or even physical access to hardware. Understanding threat vectors is crucial for organizations to develop effective security measures, as it allows them to identify potential entry points that could be targeted by attackers.

By recognizing the various threat vectors relevant to their systems, security professionals can prioritize their efforts in patching vulnerabilities, enhancing awareness to prevent social engineering attacks, and implementing appropriate security controls. This understanding enables proactive defense strategies that mitigate risks and protect organizational assets effectively.

The other options do not align with the concept of a threat vector. For example, physical security assessments and protocols for incident response do not specifically describe the methods of attack utilized by threat actors, and a measurement of risk impact focuses on the consequences of a threat rather than the method of delivery.
