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

For healthcare & life sciences organizations, EXT-05 is a key component of a compliant Microsoft 365 security posture. TrueConfig helps you implement and maintain this control while meeting industry-specific requirements.
