What must be marked on classified information that is authorized for foreign disclosure?

Classified information authorized for foreign disclosure must be marked with both classification and control markings to ensure that the information is handled properly and that the recipients are aware of its sensitivity level. The classification marking indicates the level of confidentiality, such as Confidential, Secret, or Top Secret, and informs users of the handling procedures required. Control markings, such as "Foreign Disclosure Authorized" or similar indications, specify the conditions under which foreign disclosure can occur, highlighting the fact that certain information is permissible for sharing with specific foreign allies or partners.

This dual-marking requirement is essential for maintaining compliance with security protocols and protecting national security interests. It helps ensure that individuals who come into contact with the information understand both its importance and the constraints on its dissemination. Proper markings also facilitate accountability and compliance tracking when dealing with sensitive information shared among allies.
