In network security, what does the term "attack vector" refer to?

The term "attack vector" refers to the method used to compromise a system. It encompasses the various pathways or techniques an attacker can exploit to gain unauthorized access to a network or system. Understanding attack vectors is crucial for network security as it helps in identifying potential vulnerabilities and implementing measures to defend against them.

For example, common attack vectors include phishing emails that trick users into providing sensitive information, vulnerabilities in software that can be exploited, or physical access to a network through unprotected devices. By recognizing the specific methods attackers might use, security professionals can better strategize their defenses, such as deploying firewalls, intrusion detection systems, and user education to mitigate risks associated with those vectors.
