Third-Party Enterprise App Permissions for Financial Services & Banking
How financial services & banking organizations should implement APP-06 for Microsoft 365 security and compliance.
For financial services & banking companies using Microsoft 365, third-party enterprise app permissions is a security priority. This guide explains how APP-06 helps financial services & banking organizations protect their identity infrastructure while meeting industry-specific compliance mandates.
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-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 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
