Sometimes referred to as a security level. SOURCE: FIPS 186 Security Tag – Information unit containing a representation of certain securityrelated information (e.g., a restrictive attribute bit map). SOURCE: FIPS 188 Security Target – Common Criteria specification that represents a set of security requirements to be used as the basis of an evaluation of an identified Target of Evaluation (TOE). SOURCE: CNSSI-4009 Security Test & Evaluation – (ST&E) Security Testing – Examination and analysis of the safeguards required to protect an information system, as they have been applied in an operational environment, to determine the security posture of that system.

SP 800-53 Note: Organizations subordinate to federal agencies may use the term Senior Information Security Officer or Chief Information Security Officer to denote individuals filling positions with similar responsibilities to Senior Agency Information Security Officers.

SOURCE: CNSSI-4009 Sensitive Information – Information, the loss, misuse, or unauthorized access to or modification of, that could adversely affect the national interest or the conduct of federal programs, or the privacy to which individuals are entitled under 5 U.S.C.

SOURCE: CNSSI-4009 Sensitivity – A measure of the importance assigned to information by its owner, for the purpose of denoting its need for protection. SOURCE: SP 800-60; CNSSI-4009 Sensitivity Label – Information representing elements of the security label(s) of a subject and an object. Sensitivity labels are used by the trusted computing base (TCB) as the basis for mandatory access control decisions. See security label.
