CUI is sensitive information that does not meet the criteria for classification but must still be protected. It is Government-created or owned UNCLASSIFIED information that allows for, or requires, safeguarding and dissemination controls in accordance with laws, regulations, or Government-wide policies.
CUI is a control marking, not a classification marking.
CUI policy provides a uniform marking system across the Federal Government that replaces a variety of agency-specific markings, such as FOUO, LES, SBU, etc.
CUI markings alert recipients that special handling may be required to comply with law, regulation, or Government-wide policy.
The DoD CUI Registry contains information on every category to include a description of the category, required markings, authorities and DoD policies, and examples of the type of information that may fit into the category.Not every category or authority listed in the Registry will be applicable to DoD.
