classified

Refers to information (stored or conveyed, in any form) that is formally required by a security policy to receive data confidentiality service and to be marked with a security label (which, in some cases, might be implicit) to indicate its protected status. (See: classify, collateral information, SAP, security level. Compare: unclassified.)

Usage: Usually understood to involve data confidentiality, but IDOCs SHOULD make this clear when data also is sensitive in other ways and SHOULD use other terms for those other sensitivity concepts. (See: sensitive information, data integrity.)

Mainly used by national governments, especially by the military, but the underlying concept also applies outside of governments.

"Information that has been determined pursuant to Executive Order 12958 or any predecessor Order, or by the Atomic Energy Act of 1954, as amended, to require protection

against unauthorized disclosure and is marked to indicate its classified status." [C4009]
