Internal App Registration Permissions for Legal Services
How legal services organizations should implement APP-03 for Microsoft 365 security and compliance.
For legal services companies using Microsoft 365, internal app registration permissions is a security priority. This guide explains how APP-03 helps legal services organizations protect their identity infrastructure while meeting industry-specific compliance mandates.
Why Legal Services Organizations Need This Control
Legal Services organizations face specific regulatory requirements including soc2, iso27001, 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 legal services environment, consider:
- **Regulatory requirements**: soc2, iso27001, cis may mandate specific configurations
- **Risk tolerance**: Legal Services 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

Why This Control Matters for Legal
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 legal services:
- • Business email compromise impersonating partners
- • Wire fraud in real estate transactions
- • Targeted attacks on high-profile cases
