Classification management procedures call for the timely issuance of comprehensive guidance regarding classification of information concerning any system, plan, program, project, or mission under the jurisdiction of the OCA, the unauthorized disclosure of which reasonably could be expected to cause damage to national security. Precise classification guidance is prerequisite to effective and efficient information security and assures that security resources are expended to protect only that which truly warrants protection in the interests of national security. Reference (d) and its implementing guidance, Reference (e), provide general requirements and standards concerning the issuance of security classification guides while Reference (f) provides DoD guidance on development, promulgation, distribution, maintenance, and cancellation of security classification guides.
