What does the abbreviation "CUI" mean in relation to foreign disclosure?

The abbreviation "CUI" stands for Controlled Unclassified Information. This term is vital in the context of foreign disclosure because it refers to sensitive information that must be handled and protected even though it is not classified. This information may require protection under various laws, regulations, or government wide policies.

Controlled Unclassified Information is managed to ensure that it does not inadvertently get disclosed inappropriately, which could be detrimental to national security interests or foreign relations. The protection mechanisms around CUI help maintain the integrity of U.S. government operations and maintain trust with international partners.

The other terms do not accurately capture the definition of CUI. For example, "Civilian Unclassified Information" incorrectly implies a civilian context that isn't officially associated with the structured protections CUI requires. "Classified Unrestricted Information" and "Classified Under International law" do not align with the CUI framework, as they conflate unclassified information with concepts related to classified material, which are governed by entirely different sets of rules and handling procedures.
