NISPOM
National Industrial Security Program Operating Manual (32 CFR Part 117)
The NISPOM is the National Industrial Security Program Operating Manual — codified as 32 CFR Part 117 — that sets the requirements cleared contractors must follow to protect classified information. DCSA administers it for most of the defense industrial base.
What it is
A federal rule (since 2021, 32 CFR Part 117) covering how cleared companies safeguard classified information: facility clearances, personnel security, physical security, classification management, and reporting.
Why it exists
It gives contractors across many agencies one consistent industrial-security standard rather than agency-by-agency rules, and makes those requirements legally binding as a regulation.
Who it applies to
Contractors holding a Facility Clearance and performing on classified contracts under the National Industrial Security Program.
