The Federal Register published the final rule titled "National Industrial Security Program Operating Manual (NISPOM)" (32 CFR part 117) on Dec. 21, 2020. The rule can be found here. https://www.federalregister.gov/documents/2020/12/21/2020-27698/national-industrial-security-program-operating-manual-nispom Click the title for more information.
The NISPOM establishes requirements for the protection of classified information disclosed to or developed by contractors, licensees, grantees, or certificate holders to prevent unauthorized disclosure.
In addition to adding the NISPOM to the Code of Federal Regulations (CFR), this rule incorporates the requirements of Security Executive Agent Directive (SEAD) 3, "Reporting Requirements for Personnel with Access to Classified Information or Who Hold a Sensitive Position." SEAD 3 requires reporting by all contractor cleared personnel who have been granted eligibility for access to classified information.
Comments must be received by February 21. The rule will become effective February 24, 2021, and authorizes the contractor no more than 6 months to comply with changes from the effective date of the rule.
