Third-Party Enterprise App Permissions for Legal Services
How legal services organizations should implement APP-06 for Microsoft 365 security and compliance.
Legal Services organizations face unique security challenges when managing Microsoft 365 environments. The APP-06 control (Third-Party Enterprise App Permissions) is particularly important for this sector due to soc2 and iso27001 requirements.
Why Legal Services Organizations Need This Control
Legal Services organizations face specific regulatory requirements including soc2, iso27001, cis. The APP-06 control helps address these requirements by:
- Third-party enterprise apps with elevated permissions are identified and reviewed
- External vendor apps with Directory.ReadWrite.All, Mail.ReadWrite.All are flagged
- Each third-party app with elevated permissions has documented vendor assessment
- Quarterly review of third-party app permissions is conducted
Third-party enterprise apps are applications from external vendors that you consented to but do not control. These apps pose supply chain risk - a compromised vendor could access your tenant data. Review vendor security certifications and limit permissions to minimum necessary.
Industry-Specific Considerations
When implementing APP-06 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
Implementation Steps
To implement APP-06 in your Microsoft 365 environment:
- Third-party enterprise apps with elevated permissions are identified and reviewed
- External vendor apps with Directory.ReadWrite.All, Mail.ReadWrite.All are flagged
- Each third-party app with elevated permissions has documented vendor assessment
- Quarterly review of third-party app permissions is conducted
This control requires manual implementation through the Entra admin center.
