Department of Defense (DoD) Index of Security Classification Guides (SCGs) assists DOD component officials in determining whether their existing security classification guidance may be relevant to their systems, programs, plans, or projects. The Index is limited and marked as Distribution C: Distribution Authorized to U. S. Government Agencies and their Contractors.
To access the SCG Index, you must be a registered DTIC user and access the SCGs via the R&E Gateway.
