Internal App Registration Permissions for ISO 27001 Compliance
Learn how APP-03 helps you meet ISO 27001 requirements for Microsoft 365 and Entra ID security.
Organizations pursuing ISO 27001 compliance need to address internal app registration permissions as part of their security program. The APP-03 control maps directly to ISO 27001 requirements, helping demonstrate compliance while strengthening your security posture.
How APP-03 Addresses ISO 27001 Requirements
ISO 27001 requires organizations to implement controls around internal app registration permissions. The APP-03 control provides:
- Internal app registrations with high-privilege Graph permissions are documented and reviewed quarterly
- Permissions like Mail.ReadWrite.All, Directory.ReadWrite.All, and RoleManagement.ReadWrite.Directory are flagged
- Each internal app with elevated permissions has documented business justification
These measures directly support ISO 27001 compliance by ensuring proper applications 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
Internal app registrations are applications you created and control. While you own the code, misconfigured permissions can expose excessive access. Regular review ensures your own apps only have necessary permissions.
Implementing APP-03 is an important step toward ISO 27001 compliance. Combined with TrueConfig's continuous monitoring, you can demonstrate ongoing adherence to ISO 27001 requirements.
