CMMC GLOSSARY // DIBCAC

What is DIBCAC?

DIBCAC stands for Defense Industrial Base Cybersecurity Assessment Center. DIBCAC is the DoD organization that conducts government-led high assessments and CMMC Level 3 assessments.

The Defense Industrial Base Cybersecurity Assessment Center (DIBCAC) performs the government-led assessments that sit above the C3PAO tier — including CMMC Level 3, which adds NIST SP 800-172 enhanced controls.

DIBCAC assessments also produce the authoritative scores that have exposed gaps between self-reported SPRS numbers and reality, as in the LOGZONE case.

Level 3 (DIBCAC-assessed) requirements begin phasing in at Phase 3 on November 10, 2027, for programs handling the most sensitive CUI.
