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