CMMC Readiness in GCC High: How to Conduct an Effective Internal Audit

Blog Article

With the Cybersecurity Maturity Model Certification (CMMC) now a contract requirement for many Department of Defense (DoD) contractors, internal audits are no longer optional—they're essential. In a Microsoft GCC High environment, preparing for a CMMC Level 2 or 3 audit means validating every control across your infrastructure, endpoints, and users.


This article outlines how to conduct a readiness assessment in GCC High and how expert GCC High migration services help lay the groundwork for a successful audit.






1. Align Your Environment with NIST 800-171 Baselines


CMMC Level 2 maps directly to NIST 800-171. In GCC High:





  • Ensure system security plans (SSPs) reflect current architecture




  • Validate that your enclave is segmented from non-compliant workloads




  • Verify controls around access, encryption, and logging




✅ Start by confirming your infrastructure supports the right control family requirements.






2. Use Microsoft Purview Compliance Manager


GCC High tenants can use Compliance Manager to:





  • Assess current posture against CMMC or NIST 800-171




  • Identify gaps and track remediation activities




  • Generate exportable evidence for assessors




✅ It’s your audit trail and action plan in one place.






3. Review Access and Identity Management Practices


Audit your identity policies to ensure:





  • Enforced Multi-Factor Authentication (MFA)




  • Least-privilege access across all accounts




  • Role-based access controls and just-in-time access (if applicable)




✅ Review group memberships, admin roles, and service accounts for privilege creep.






4. Examine Logging, Monitoring, and Incident Response


An internal audit should cover:





  • Sentinel and Defender alert configurations




  • Retention policies for audit logs (e.g., 12+ months)




  • Incident response plans tied to specific CUI scenarios




✅ Your logs must not only exist—they must be centralized, searchable, and secured.






5. Simulate an Assessment Walkthrough


Treat your internal audit like a live C3PAO assessment:





  • Interview users and IT admins to test process understanding




  • Review training records and policy acknowledgments




  • Collect artifacts (e.g., screenshots, system configs, logs)




✅ GCC High migration services can help prepare documentation and identify evidence gaps before they become audit failures.






CMMC audits require more than technical controls—they demand readiness, documentation, and a story that shows how your organization protects CUI. By leveraging GCC High’s native tools and conducting thorough internal audits, you can walk into your assessment with confidence. Expert GCC High migration services ensure your environment is compliant and audit-ready from day one.
