Which term describes a weakness that can be exploited in an information system?

The term that describes a weakness in an information system that can be exploited is "vulnerability." A vulnerability refers to a flaw or a gap in the system's security mechanisms that could be used by an attacker to compromise the system's confidentiality, integrity, or availability. Understanding vulnerabilities is crucial in the field of computer security, as identifying and addressing these weaknesses helps protect systems from potential threats and attacks.

In contrast, integrity relates to the assurance that information is accurate and trustworthy, while threats refer to potential events or circumstances that could exploit vulnerabilities to cause harm. Access control is a security measure that restricts who or what can access certain information or systems. Understanding these terms helps in the broader context of information security, but vulnerability specifically pinpoints the weakness that could be exploited.
