Assessors accept boundary diagrams that show the true system boundary, key internal boundaries, and CUI flows, supported by evidence that matches the SSP and CMMC scoping.

Entra ID Privileged Identity Management removes standing admin rights in CUI tenants and replaces them with time-bound, approved, and audited elevation that you can tie to Conditional Access and evidence collection for NIST 800-171 and CMMC Level 2.

For CUI environments, the defensible path is hardware-backed authenticators such as PIV/CAC-style certificates and FIDO2/WebAuthn, enforced through Microsoft Entra policy and supported by CISA guidance, with MFA obligations mapped to CMMC Level 2 controls.

Sensitivity labels in Microsoft Purview set the digital markings and protections that keep CUI identifiable and controlled across Microsoft 365, and they integrate with DLP and audit to support NIST SP 800-171 and CMMC Level 2 practice implementation.

Microsoft offers Microsoft 365 Copilot in GCC High within the sovereign tenant boundary, but feature gaps, web grounding choices, and CUI governance needs define where you can use it.

Mobile endpoints enter the CUI boundary as soon as users access or store CUI on them, so you need clear scope, NIST SP 800-171 controls applied to iOS and Android, and enforceable MDM or MAM policies before you allow mobile access.
