Internal App Registration Permissions for Financial Services & Banking
How financial services & banking organizations should implement APP-03 for Microsoft 365 security and compliance.
Financial Services & Banking organizations face unique security challenges when managing Microsoft 365 environments. The APP-03 control (Internal App Registration Permissions) is particularly important for this sector due to soc2 and pci-dss requirements.
Why Financial Services & Banking Organizations Need This Control
Financial Services & Banking organizations face specific regulatory requirements including soc2, pci-dss, nist-800-53, iso27001. 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 financial services & banking environment, consider:
- **Regulatory requirements**: soc2, pci-dss, nist-800-53 may mandate specific configurations
- **Risk tolerance**: Financial Services & Banking organizations typically have moderate to low risk tolerance
- **Audit frequency**: Plan for regular compliance reviews
- **Documentation**: Maintain detailed records for regulatory inspections
Implementation Steps
To implement APP-03 in your Microsoft 365 environment:
- 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
This control requires manual implementation through the Entra admin center.
