Which label is typically applied to highly sensitive information meant for viewing only by approved persons?

The label typically applied to highly sensitive information meant for viewing only by approved persons is "Confidential." This classification indicates that the information is sensitive in nature and access is restricted to individuals who have been authorized to view it. In many organizations, "Confidential" serves as a standard classification for documents that require protection from unauthorized disclosure, ensuring that only designated personnel can access the data.

In the context of information security classifications, "Confidential" can cover a broad range of sensitive information that, if disclosed, could cause harm to individuals or the organization. This classification is crucial in creating policies around data handling and access control, emphasizing the importance of safeguarding sensitive information.

While "Top Secret" and "Secret" also refer to classifications of sensitive information, they generally apply to much higher sensitivity levels (often associated with government or military classifications). "Critical" typically refers to information that, while important, may not carry the same level of restrictive access as "Confidential." Hence, "Confidential" is the most appropriate label for sensitive information designated for specific authorized individuals.
