What is a “vulnerability” in the context of IT security?

A vulnerability in the context of IT security refers to a weakness in a system, application, or network that can be exploited by threats to gain unauthorized access, disrupt services, or compromise data integrity. Identifying and understanding vulnerabilities is crucial for organizations because these weaknesses can serve as entry points for cyber attackers, allowing them to carry out various malicious activities.

Next, addressing the other choices provides a clearer picture of why they do not fit the definition of a vulnerability. A strength in security protocols would refer to the protective measures in place, which is the opposite of a vulnerability. A feature enhancing user experience is unrelated to security specifically and instead pertains to usability and interface design. A type of malware describes malicious software aimed at causing harm, which is fundamentally different from a vulnerability; malware exploits vulnerabilities rather than being one itself.
