Configure tenant governance permissions for Microsoft Sentinel

Security groups used in the relationship template are synchronized to the governed tenant as "remote tenant groups." You can assign these groups to Microsoft Sentinel roles in the governed tenant to enable multitenant management capabilities. You can assign these groups to Defender URBAC or Azure Resource Manager (ARM) resources to enable Microsoft Sentinel management capabilities.

Assigning Microsoft Sentinel roles enables multitenant management features including:

  • Content distribution
  • Direct management through the Defender portal

Option 1 - Assign permissions with URBAC

To create custom roles in Microsoft Defender unified RBAC, you must be assigned one of the following roles or permissions:

  • At least Security Administrator in Microsoft Entra ID.
  • All Authorization permissions assigned in Microsoft Defender Unified RBAC.

Follow these steps to grant Microsoft Sentinel permissions to your delegated remote tenant group.

  1. In the governed tenant, sign in to the Defender Portal

  2. Navigate to Setup & Configuration > Permissions.

  3. Select Roles.

  4. Select or Create the role you want to assign (Map Sentinel roles to Defender URBAC).

  5. Create a new assignment or edit an existing one.

  8. Select Add to complete the assignment.

Option 2 - Assign permissions to a resource group

The Microsoft Sentinel Azure RBAC assignments described in this section grant management-plane access to the selected resources. They don't automatically grant data-plane access, such as permission to read Azure Storage blob data or Azure Key Vault secrets. Assign any required data-plane roles separately and follow least-privilege principles.

Assigning Microsoft Sentinel roles enables multitenant management features including:

  • Content distribution
  • Direct management through the Defender portal

Assign permissions to resource group

Before you assign permissions, ensure you have the User Access Administrator role in Azure RBAC and at least the User Administrator role in Entra RBAC.

Follow these steps to grant Microsoft Sentinel permissions to your delegated access groups.remote tenant group.

  1. In the governed tenant, sign in to the Azure portal.
