Restrict User App Registration for Government & Public Sector
How government & public sector organizations should implement APP-12 for Microsoft 365 security and compliance.
For government & public sector companies using Microsoft 365, restrict user app registration is a security priority. This guide explains how APP-12 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-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 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-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.
Follow the steps above in your Microsoft Entra admin center to enable this control.
Government Compliance Requirements
Government organizations must comply with these frameworks, all of which address restrict user app registration:
Why This Control Matters for Government
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.
Common threats in government & public sector:
- • Nation-state espionage campaigns
- • Ransomware targeting critical services
- • Insider threats from privileged users
For government & public sector organizations, APP-12 is a key component of a compliant Microsoft 365 security posture. TrueConfig helps you implement and maintain this control while meeting industry-specific requirements.
