Audit Mailbox Delegation for SOC 2 Compliance
Learn how EXT-08 helps you meet SOC 2 requirements for Microsoft 365 and Entra ID security.
Organizations pursuing SOC 2 compliance need to address audit mailbox delegation as part of their security program. The EXT-08 control maps directly to SOC 2 requirements, helping demonstrate compliance while strengthening your security posture.
How EXT-08 Addresses SOC 2 Requirements
SOC 2 requires organizations to implement controls around audit mailbox delegation. The EXT-08 control provides:
- SendAs permissions on mailboxes are documented
- SendOnBehalf permissions are tracked
- FullAccess mailbox permissions are reviewed
- Delegation changes are monitored
These measures directly support SOC 2 compliance by ensuring proper external security in your Microsoft 365 environment.
Implementation for Compliance
To satisfy SOC 2 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 SOC 2 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 SOC 2
Mailbox delegation enables users to send email as others or access their mailboxes. Unauthorized delegation can be used for impersonation attacks or to access sensitive communications without detection.
Implementing EXT-08 is an important step toward SOC 2 compliance. Combined with TrueConfig's continuous monitoring, you can demonstrate ongoing adherence to SOC 2 requirements.
