Conditions for 2.1.9 (L1) Ensure DKIM is enabled for all Exchange Online Domains (Automated)
Validate test for a pass:
- Confirm that the automated test results align with the manual audit steps outlined in the CIS benchmark.
- Specific conditions to check:
- Condition A: DKIM is enabled for all Exchange Online domains in the Microsoft 365 security center.
- Condition B: Using the Exchange Online PowerShell Module, the `CnameConfiguration.Enabled` property for each domain is set to `True`.
Validate test for a fail:
- Confirm that the failure conditions in the automated test are consistent with the manual audit results.
- Specific conditions to check:
- Condition A: DKIM is not enabled for one or more Exchange Online domains in the Microsoft 365 security center.
- Condition B: Using the Exchange Online PowerShell Module, the `CnameConfiguration.Enabled` property for one or more domains is set to `False`.
