TL;DR: CMMC 2.0 readiness for manufacturers often fails on routine access decisions rather than policy gaps, with shared accounts, inconsistent MFA, weak session handling, and broad privilege making CUI systems harder to defend and audit, according to Imprivata. The practical issue is that plant-floor workflows can quietly invalidate identity controls unless access is tied cleanly to individuals and actions.
Editorial analysis by NHI Mgmt Group, based on content published by Imprivata: “CMMC 2.0 for manufacturers: Where access control breaks down on the shop floor”.
Key questions
Q: What breaks when shared accounts are used on manufacturing workstations under CMMC 2.0?
A: Shared accounts break person-level accountability.
Q: Why do inconsistent MFA deployments create CMMC readiness risk in factories?
A: Because assessment quality depends on coverage, not intent.
Q: How do you know whether session handling is strong enough for shared workstations?
A: Look for automatic lock, reauthentication after inactivity, and clear session end behaviour that prevents one operator's access from carrying into the next task or shift.
Practitioner guidance
- Standardise unique operator identity at shared stations Replace generic logins and reused credentials with individual authentication that preserves person-level attribution on every workstation that can reach CUI systems.
- Close inconsistent MFA paths Inventory all routes to systems that store or process CUI, then remove the exceptions where strong authentication is missing or only partly enforced.
- Tighten session handling on communal endpoints Configure automatic lock, reauthentication, and session termination so an unattended workstation cannot continue under another operator's context.
Bottom line: CMMC 2.0 readiness in manufacturing is often undermined by routine access choices, especially where shared endpoints blur user attribution.

Shared-workstation access control is a CMMC readiness issue, not a narrow login problem. Manufacturing environments do not fail assessments because they lack policy language. They fail when one workstation supports many operators, many shifts, and many exceptions, while the identity model still assumes a single user context. That makes accountability, session control, and evidence collection the real test. Practitioners should treat communal access as a governance design problem, not a user convenience issue.
A question worth separating out:
Q: What is the difference between least privilege and shared access in manufacturing environments?
A: Least privilege limits what a named individual can do, while shared access dilutes attribution and usually expands effective permissions to fit the broadest user need. In manufacturing, shared stations often tempt teams to overgrant access for speed, but that trade-off makes later audit and accountability much harder.
