A vulnerability is discovered on a network. If successfully exploited, it will completely remove the ability of the system to limit disclosure of information to an unauthorized user. Which concept…

While it relates to confidentiality, the impact is described as 'completely removing the ability to limit disclosure,' which implies a high impact, not 'none.'

Availability refers to the ability of authorized users to access information and systems when needed, which is not the primary impact described.

Availability is not the correct concept, as the vulnerability deals with unauthorized disclosure of information, not the system's ability to remain accessible.

This vulnerability directly affects the 'confidentiality' aspect of the CIA triad (Confidentiality, Integrity, Availability) because it concerns the disclosure of information to unauthorized users. Since it will 'completely remove the ability of the system to limit disclosure,' this indicates a significant, or 'high,' impact on confidentiality, meaning sensitive data could be fully exposed.
