What does it mean when information is labeled "Sensitive but Unclassified" (SBU)?

When information is labeled "Sensitive but Unclassified" (SBU), it indicates that the information requires a level of protection due to its sensitive nature, but it does not meet the criteria for classified information. This designation acknowledges that while the information is not classified, its disclosure could still compromise personal privacy, violate proprietary rights, or harm national security interests. Therefore, SBU information must be handled with care, and individuals who have access to it must understand the potential consequences of unauthorized disclosure.

In contrast, the other options do not accurately reflect the definition of SBU. Sharing SBU information freely without restrictions would endanger its sensitivity. The classification of "top secret" applies to a different category of information that requires even stricter controls and protections. Lastly, labeling SBU information as open to public access contradicts its purpose, as such information is considered sensitive enough to warrant protection despite being unclassified.
