What is the distinction between a security threat and a vulnerability?

The distinction between a security threat and a vulnerability is rooted in their definitions and implications for network security. A security threat represents a potential occurrence that could cause harm or damage to a system, network, or data. For example, threats can manifest as malware attacks, phishing attempts, or insider threats. Essentially, they are scenarios that might happen and potentially lead to data breaches or service disruptions.

On the other hand, a vulnerability refers to a weakness or flaw within a system that can be exploited by an attacker to gain unauthorized access or cause harm. This could be a software bug, misconfigured system settings, or outdated software that leaves an organization susceptible to threats.

Therefore, the correct answer reveals that while a security threat emphasizes the possibility of adverse events, a vulnerability highlights the inherent weaknesses that enable those threats to take effect. Understanding this relationship is crucial for developing effective network security strategies.
