Limit Global Administrators to 2-4 for ISO 27001 Compliance
Learn how PA-01 helps you meet ISO 27001 requirements for Microsoft 365 and Entra ID security.
Meeting ISO 27001 standards for Microsoft 365 involves implementing controls like PA-01 (Limit Global Administrators to 2-4). This guide covers the specific ISO 27001 requirements addressed by this control and how to achieve compliance.
How PA-01 Addresses ISO 27001 Requirements
ISO 27001 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 ISO 27001 compliance by ensuring proper privileged_access security in your Microsoft 365 environment.
Implementation for Compliance
To satisfy ISO 27001 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 ISO 27001 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 ISO 27001
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 ISO 27001 compliance. Combined with TrueConfig's continuous monitoring, you can demonstrate ongoing adherence to ISO 27001 requirements.
