Limit Global Administrators to 2-4 for NIST 800-53 Compliance

Learn how PA-01 helps you meet NIST 800-53 requirements for Microsoft 365 and Entra ID security.

Meeting NIST 800-53 standards for Microsoft 365 involves implementing controls like PA-01 (Limit Global Administrators to 2-4). This guide covers the specific NIST 800-53 requirements addressed by this control and how to achieve compliance.

How PA-01 Addresses NIST 800-53 Requirements

NIST 800-53 requires organizations to implement controls around limit global administrators to 2-4. The PA-01 control provides:

  • Between 2 and 4 principals have the Global Administrator role
  • No single point of failure (minimum 2)
  • Attack surface is minimized (maximum 4)
  • No service principals have Global Administrator (use least-privilege)
  • No groups have Global Administrator (hidden privilege escalation risk)

These measures directly support NIST 800-53 compliance by ensuring proper privileged_access security in your Microsoft 365 environment.

Implementation for Compliance

To satisfy NIST 800-53 requirements with this control:

  • **Enable the control** - Follow the manual configuration steps
  • **Document your implementation** - Record how the control was configured
  • **Maintain evidence** - TrueConfig automatically logs compliance status
  • **Monitor continuously** - Track any deviations from the expected state

Evidence Collection

For NIST 800-53 audits, you'll need to demonstrate:

  • Current configuration state
  • Historical compliance data
  • Remediation actions taken
  • Continuous monitoring in place

TrueConfig provides all of this evidence through its audit trail and reporting features.

Why This Control Matters for NIST 800-53

Global Administrators have unrestricted access to your entire tenant. Too many increases your attack surface; too few risks lockout. Service principals and groups with Global Admin are especially dangerous - service principals can be compromised via app credentials, and groups hide who actually has the role. Microsoft recommends 2-4 permanent Global Admins for most organizations.

Implementing PA-01 is an important step toward NIST 800-53 compliance. Combined with TrueConfig's continuous monitoring, you can demonstrate ongoing adherence to NIST 800-53 requirements.
