Cross-Tenant Access Policy Review for Healthcare & Life Sciences
How healthcare & life sciences organizations should implement EXT-05 for Microsoft 365 security and compliance.
For healthcare & life sciences companies using Microsoft 365, cross-tenant access policy review is a security priority. This guide explains how EXT-05 helps healthcare & life sciences organizations protect their identity infrastructure while meeting industry-specific compliance mandates.
Why Healthcare & Life Sciences Organizations Need This Control
Healthcare & Life Sciences organizations face specific regulatory requirements including hipaa, soc2, nist-800-53. The EXT-05 control helps address these requirements by:
- Default cross-tenant access policy is not overly permissive
- Partner-specific configurations exist for known collaborators
- Inbound and outbound B2B access is explicitly controlled
Permissive cross-tenant defaults allow any external organization to collaborate with your tenant. Restricting defaults and configuring partner-specific policies ensures only approved organizations can access your resources.
Industry-Specific Considerations
When implementing EXT-05 in a healthcare & life sciences environment, consider:
- **Regulatory requirements**: hipaa, soc2, nist-800-53 may mandate specific configurations
- **Risk tolerance**: Healthcare & Life Sciences 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
EXT-05 requires the following configuration:
- Default cross-tenant access policy is not overly permissive
- Partner-specific configurations exist for known collaborators
- Inbound and outbound B2B access is explicitly controlled

Why This Control Matters for Healthcare
Permissive cross-tenant defaults allow any external organization to collaborate with your tenant. Restricting defaults and configuring partner-specific policies ensures only approved organizations can access your resources.
Common threats in healthcare & life sciences:
- • Ransomware targeting patient records
- • Business email compromise impersonating physicians
- • Insider threats from staff with excessive access
