Confidentiality level

Military
Applicable to DoD information systems, the confidentiality level

"is primarily used to establish acceptable access factors, such as requirements for individual security clearances or background investigations, access approvals, and need-to-know determinations; interconnection controls and approvals; and acceptable methods by which users may access the system (e.g., intranet, Internet, wireless). The Department of Defense has three defined confidentiality levels: classified, sensitive, and public."
