TL;DR: CMMC 2.0 shifts defense contractors from claimed compliance to verified proof, with identity controls, audit trails, and evidence of enforced access rules now central to bid eligibility under the DoD’s assessment model. Secret Double Octopus frames the biggest risk as inconsistent identity enforcement across legacy systems, shared accounts, remote access, and privileged workflows, where proof is often weaker than policy.
Editorial analysis by NHI Mgmt Group, based on content published by Secret Double Octopus: “CMMC 2.0 and the Identity Imperative: What Defense Contractors Need to Know”.
Key questions
Q: What breaks in CMMC 2.0 when identity controls are only documented, not enforced?
A: The control set becomes hard to verify.
Q: Why do legacy remote access paths create the most CMMC audit risk?
A: Legacy remote access often bypasses the strongest identity controls, relies on older authentication patterns, or leaves attribution gaps in logs.
Q: How should contractors prioritize identity work before a CMMC assessment?
A: Start with the systems that handle CUI and the access paths that are least visible: shared accounts, remote administration, VPN, RDP, SSH, and legacy apps.
Practitioner guidance
- Map every FCI and CUI access path Document every route into in-scope environments, including VPN, RDP, SSH, shop-floor workstations, shared admin jump paths, and legacy applications.
- Eliminate shared and inherited identities Remove shared logins, pool accounts, and informal admin handoffs from systems that touch CUI.
- Prepare assessor-ready identity evidence Build a repeatable evidence set for MFA enforcement, login logs, privileged activity, and authentication changes.
Bottom line: CMMC 2.0 turns identity governance into a proof exercise, where contractors must demonstrate controlled access rather than merely describe it.

Identity evidence is now the real compliance product: CMMC 2.0 does not reward the presence of controls alone. It rewards the ability to prove that authentication, access limitation, and logging operate consistently across the systems that matter. For defense contractors, the governance failure is not only insecure access, but evidence fragmentation that leaves the control set unverifiable.
A few things that frame the scale:
- Across one million observed logins, 1 in 4 were password-based rather than SSO, 2 in 5 were not protected by MFA and 1 in 5 used a weak, breached or reused password.
A question worth separating out:
Q: How do CMMC teams know whether audit logging is strong enough for identity proof?
A: Logging is strong enough when a reviewer can reconstruct a user’s access, privileged action, and authentication change from end to end without relying on manual explanation. If logs are incomplete, modifiable, or disconnected from the identity record, they do not provide the proof CMMC expects. The test is traceability, not volume.
