Multilevel Security Mode
  • A mode of operation that provides a capability for various levels and categories or compartments of data to be concurrently stored and processed in an automated system and permits selective access to such material concurrently by users who have differing security clearances and need-to-know. Internal controls, as well as personnel, physical, and administrative controls, separate users and data on the basis of security clearance. The internal security controls must be thoroughly demonstrated to be effective in preventing unauthorized access to information. (AFR 205-16;)
  • A mode of operation in effect when at least some users with access to the system do not have a security clearance or need-to-know for all classified material in the information system. This mode provides the capability for the concurrent access to and use of the information system by uncleared users and users having different security clearances and need-to-know. The identification, segregation, and control of users and sensitive material on the basis of security clearance, and material classification category, and need-to-know must be essentially under automated control. Operation in this mode should be predicated on a comprehensive demonstration that the internal security controls can effectively prevent malicious attempts to bypass these controls. (AFR 700-10;)
  • The mode of operation which allows two or more classification levels of information to be processed simultaneously within the same system when some users are not cleared for all levels of information present. (CSC-STD-003-85;; NCSC-WA-001-85;)
  • A mode of operation wherein not all users have a clearance, formal access approval, and/or need-to-know for all data handled by the AIS. (DODD 5200. 28;)
  • A mode of operation under an operating system (supervisor or executive program) which provides a capability permitting various levels and categories or compartments of material to be concurrently stored and processed in an ADP system. In a remotely accessed resource-sharing system, the material can be selectively accessed and manipulated from variously controlled terminals by personnel having different security clearances and access approvals. This mode of operation can accommodate the concurrent processing and storage of: a) two or more levels of classified data, or b) one or more levels of classified data with unclassified data depending upon the constraints placed on the system by the Designated Approving Authority. (DODD 5200. 28M;)
  • An operation under an operating system (supervisor or executive program) which provides a capability permitting various categories and types of classified materials to be stored and processed concurrently in an ADP system and permitting selective access to such material concurrently by uncleared users having differing security clearances and need-to-know is accordingly accomplished by the operating system and associated system software. In a remotely accessed resource-sharing system, the material can be selectively accessed and manipulated from variously controlled terminals by personnel having different security clearances and need-to-know. This mode of operation can accommodate the concurrent processing and storage of: a) two or more levels of classified data, or b) one or more levels of classified data with unclassified data depending upon constraints placed on the system by the DAA (OPNAVINST 5239. 1A;)
