Information Security Oversight Office (ISOO)

ISOO Notices

The Information Security Oversight Office issues ISOO Notices to disseminate and provide consistent guidance to Federal Agencies, in an effort to improve their classified national security information programs. Each ISOO Notice focuses on a single topic related to classification, safeguarding, or declassification.

Due to the issuance of Executive Order 13526 and the revision to 32 C.F.R part 2001, many of the original notices have been revised, cancelled, or superseded. The notices listed reflect these changes.

**Please note all notices are in PDF format
