Detect External Mail Forwarding for Healthcare & Life Sciences

How healthcare & life sciences organizations should implement EXT-07 for Microsoft 365 security and compliance.

For healthcare & life sciences companies using Microsoft 365, detect external mail forwarding is a security priority. This guide explains how EXT-07 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-07 control helps address these requirements by:

  • Mailbox forwarding rules to external addresses are identified
  • Inbox rules forwarding to external domains are flagged
  • No unexpected external forwarding rules exist

Attackers commonly set up mail forwarding rules after compromising accounts. These rules silently copy all emails to external addresses, enabling ongoing data theft even after the initial compromise is remediated.

Industry-Specific Considerations

When implementing EXT-07 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-07 requires the following configuration:

  • Mailbox forwarding rules to external addresses are identified
  • Inbox rules forwarding to external domains are flagged
  • No unexpected external forwarding rules exist

Requires Exchange admin access or Microsoft Graph Reports API

Follow the steps above in your Microsoft Entra admin center to enable this control.

Why This Control Matters for Healthcare

Attackers commonly set up mail forwarding rules after compromising accounts. These rules silently copy all emails to external addresses, enabling ongoing data theft even after the initial compromise is remediated.

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-07 is a key component of a compliant Microsoft 365 security posture. TrueConfig helps you implement and maintain this control while meeting industry-specific requirements.
