What does the SAP banner marking indicate?

The SAP banner marking indicates a Special Access Requirement or SAR. This marking signifies that the information is not only classified but also has additional access restrictions that go beyond the usual classification levels. It is used for sensitive information where access is limited to individuals who have both the appropriate security clearance and the need to know. This ensures that only those with a special need to access the information can do so, enhancing security protocols around highly sensitive materials.

The distinction that the SAP banner marking provides is crucial for managing and protecting information that may involve national security or other critical sensitive issues. Access to this type of information is tightly controlled, which is why it is categorized differently from general classified information.
