Audit Mailbox Delegation for PCI DSS Compliance
Learn how EXT-08 helps you meet PCI DSS requirements for Microsoft 365 and Entra ID security.
PCI DSS compliance requires implementing specific controls around audit mailbox delegation. This page explains how TrueConfig's EXT-08 control helps you meet PCI DSS requirements in your Microsoft 365 environment.
How EXT-08 Addresses PCI DSS Requirements
PCI DSS 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 PCI DSS compliance by ensuring proper external security in your Microsoft 365 environment.
Implementation for Compliance
To satisfy PCI DSS 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 PCI DSS 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 PCI DSS
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 PCI DSS compliance. Combined with TrueConfig's continuous monitoring, you can demonstrate ongoing adherence to PCI DSS requirements.
