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
