Microsoft Intune DeviceManagementConfigurationPolicies
Description
Microsoft Intune device management configuration policies are a tool administrators can use to remotely manage policies and settings on intune managed devices. This functionality can also be abused to disable defences & evade detection. This detection identifies when a new device management configuration policy has been created.

Implementation guide
The Splunk Add-on for Microsoft Cloud Services add-on is required to ingest In-Tune audit logs via Azure EventHub. To configure this logging, visit Intune > Tenant administration > Diagnostic settings > Add diagnostic settings & send events to the activity audit event hub. Deploy as a risk based alerting rule for quick deployment or perform baselining & tune accordingly.
