What do banner markings indicate on a classified document or page?

Banner markings on a classified document or page serve to indicate the highest overall classification level of the information contained within that document. This is crucial for ensuring that individuals handling the document can readily identify its sensitivity and handle it according to established protocols for that classification level.

When classified materials are being accessed or disseminated, knowing the highest classification level helps in understanding the degree of confidentiality required, the potential risks involved, and the appropriate safeguards that must be employed. Banner markings are typically displayed prominently at the top and bottom of each page to provide immediate awareness of the document’s classification for users, allowing them to act accordingly to maintain security and prevent unauthorized access. This clarity in communication is essential in environments where classified information is handled to protect national security interests.
