Restrict User App Registration for Legal Services
How legal services organizations should implement APP-12 for Microsoft 365 security and compliance.
For legal services companies using Microsoft 365, restrict user app registration is a security priority. This guide explains how APP-12 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-12 control helps address these requirements by:
- Non-admin users cannot register applications
- App registration is restricted to administrators
- authorizationPolicy.defaultUserRolePermissions.allowedToCreateApps is false
When any user can register applications, attackers and unmanaged users can create app registrations to request OAuth permissions or establish persistence. Restricting registration to administrators keeps the application attack surface governed.
Industry-Specific Considerations
When implementing APP-12 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-12 requires the following configuration:
- Non-admin users cannot register applications
- App registration is restricted to administrators
- authorizationPolicy.defaultUserRolePermissions.allowedToCreateApps is false
Detect-only. Fix in Entra admin center > User settings > Users can register applications = No.

Why This Control Matters for Legal
