Internal App Registration Permissions for Government & Public Sector
How government & public sector organizations should implement APP-03 for Microsoft 365 security and compliance.
For government & public sector companies using Microsoft 365, internal app registration permissions is a security priority. This guide explains how APP-03 helps government & public sector organizations protect their identity infrastructure while meeting industry-specific compliance mandates.
Why Government & Public Sector Organizations Need This Control
Government & Public Sector organizations face specific regulatory requirements including fedramp, nist-800-53, cis. The APP-03 control helps address these requirements by:
- 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
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.
Industry-Specific Considerations
When implementing APP-03 in a government & public sector environment, consider:
- **Regulatory requirements**: fedramp, nist-800-53, cis may mandate specific configurations
- **Risk tolerance**: Government & Public Sector organizations typically have moderate to low risk tolerance
- **Audit frequency**: Plan for regular compliance reviews
- **Documentation**: Maintain detailed records for regulatory inspections
How to Configure
APP-03 requires the following configuration:
- 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
Review flagged internal applications and remove unnecessary permissions
Follow the steps above in your Microsoft Entra admin center to enable this control.

Why This Control Matters for Government
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.
Common threats in government & public sector:
- • Nation-state espionage campaigns
- • Ransomware targeting critical services
- • Insider threats from privileged users
