2.2.1 Ensure that Auto provisioning of 'Log Analytics agent for Azure VMs' is Set to 'On'

Information

Enable automatic provisioning of the monitoring agent to collect security data.

Rationale:

When Log Analytics agent for Azure VMs is turned on, Microsoft Defender for Cloud provisions the Microsoft Monitoring Agent on all existing supported Azure virtual machines and any new ones that are created. The Microsoft Monitoring Agent scans for various security-related configurations and events such as system updates, OS vulnerabilities, endpoint protection, and provides alerts.

Solution

From Azure Portal

From Azure Home select the Portal Menu

Select Microsoft Defender for Cloud

Select Environment Settings

Select a subscription

Select Auto Provisioning in the left column.

Ensure that Log Analytics agent for Azure VMs is set to On

Repeat the above for any additional subscriptions.
From Azure CLI
Use the below command to set Automatic provisioning of monitoring agent to On.

az account get-access-token --query '{subscription:subscription,accessToken:accessToken}' --out tsv | xargs -L1 bash -c 'curl -X PUT -H 'Authorization: Bearer $1' -H 'Content-Type: application/json' https://management.azure.com/subscriptions/subscriptionID/providers/Microsoft.Security/autoProvisioningSettings/default?api-version=2017-08-01-preview -d@'input.json''

Where input.json contains the Request body json data as mentioned below.
