You can configure your instance of SQL Server enabled by Azure Arc with Microsoft Defender for Cloud by following these steps.

Prerequisites

Your Windows-based SQL Server instance is connected to Azure. Follow the instructions to Connect your SQL Server to Azure Arc.

Note

Microsoft Defender for Cloud is only supported for SQL Server instances on Windows machines. This will not work for SQL Server on Linux machines.
Your user account is assigned one of the Security Center Roles (RBAC)

Create a Log Analytics workspace

Search for Log Analytics workspaces resource type and add a new one through the creation pane.

Note

You can use a Log Analytics workspace in any region so if you already have one, you can use it. But we recommend creating it in the same region where your SQL Server enabled by Azure Arc resource is created.
Go to Agents management > Log Analytics agent instructions and copy Workspace ID and Primary key for later use.

Install Log Analytics Agent

The next step is needed only if you haven't yet configured MMA on the remote machine.

Go to Azure Arc > Servers and open the Azure Arc-enabled server resource for the machine where the SQL Server instance is installed.
Open the Extensions pane and click + Add.
Select Log Analytics Agent - Azure Arc and click Next.
Set the Workspace ID and Workspace key using the values you saved in the previous step.
After validation succeeds, select Create to install the agent. When the deployment completes, the status updates to Succeeded.
