Detect External Mail Forwarding for Zero Trust Compliance
Learn how EXT-07 helps you meet Zero Trust requirements for Microsoft 365 and Entra ID security.
Organizations pursuing Zero Trust compliance need to address detect external mail forwarding as part of their security program. The EXT-07 control maps directly to Zero Trust requirements, helping demonstrate compliance while strengthening your security posture.
How EXT-07 Addresses Zero Trust Requirements
Zero Trust requires organizations to implement controls around detect external mail forwarding. The EXT-07 control provides:
- Mailbox forwarding rules to external addresses are identified
- Inbox rules forwarding to external domains are flagged
- No unexpected external forwarding rules exist
These measures directly support Zero Trust compliance by ensuring proper external security in your Microsoft 365 environment.
Implementation for Compliance
To satisfy Zero Trust requirements with this control:
- **Enable the control** - Follow the manual configuration steps
- **Document your implementation** - Record how the control was configured
- **Maintain evidence** - TrueConfig automatically logs compliance status
- **Monitor continuously** - Track any deviations from the expected state
Evidence Collection
For Zero Trust audits, you'll need to demonstrate:
- Current configuration state
- Historical compliance data
- Remediation actions taken
- Continuous monitoring in place
TrueConfig provides all of this evidence through its audit trail and reporting features.
Why This Control Matters for Zero Trust
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.
Implementing EXT-07 is an important step toward Zero Trust compliance. Combined with TrueConfig's continuous monitoring, you can demonstrate ongoing adherence to Zero Trust requirements.
