In information security, what does the term "threat vector" refer to?

The term "threat vector" refers to the specific path or method that a hacker uses to infiltrate a computer system or network. Understanding threat vectors is crucial in the field of information security because it helps security professionals identify vulnerabilities and potential points of entry that attackers may exploit. By recognizing these vectors, organizations can implement appropriate defenses to mitigate the risks associated with various types of attacks.

For instance, a threat vector could involve tactics such as phishing emails that trick users into revealing login credentials, exploiting software vulnerabilities, or utilizing physical access to a device. Knowledge of these vectors enables security teams to enhance their security posture, develop better detection measures, and respond effectively to potential breaches.

The other choices relate to different aspects of cybersecurity but do not align with the specific definition of a threat vector. For example, the type of malware signifies the nature of an attack rather than the method of access, and defensive software focuses on prevention rather than the attack method itself. Lastly, a response plan pertains to how an organization handles incidents rather than the pathways through which incidents occur.
