Using Console

Using CLI

To remediate the “Monitor System Updates setting is not enabled” misconfiguration in Azure using Azure CLI, follow the steps below:

Open the Azure CLI on your local machine or in the Azure Portal.
Run the following command to check the current status of the “Monitor System Updates” setting:
```
az vm get-instance-view --resource-group <resource-group-name> --name <vm-name> --query "instanceView.extensions[?type=='Microsoft.Azure.Security.AzureSecurityCenter'].settings"
```
Replace <resource-group-name> and <vm-name> with the name of the resource group and virtual machine that you want to check.
If the “Monitor System Updates” setting is not enabled, run the following command to enable it:
```
az vm extension set --resource-group <resource-group-name> --vm-name <vm-name> --name AzureSecurityCenter --publisher Microsoft.Azure.Security --settings "{'monitorWindowsUpdates': true, 'monitorLinuxUpdates': true}"
```
Replace <resource-group-name> and <vm-name> with the name of the resource group and virtual machine that you want to remediate.
Once the command is executed successfully, the “Monitor System Updates” setting will be enabled for the virtual machine.

Note: The Azure Security Center must be enabled for the subscription and the virtual machine for this remediation to work.

Using Python

To remediate the “Monitor System Updates setting is not enabled” misconfiguration in Azure using Python, you can use the Azure SDK for Python. Here are the step by step instructions:

Install the Azure SDK for Python using the following command:
```
pip install azure-mgmt-monitor
```

Authenticate with Azure using your Azure credentials. You can use the following code to authenticate:

from azure.identity import DefaultAzureCredential
from azure.mgmt.monitor import MonitorManagementClient
from azure.mgmt.resource import SubscriptionClient

credential = DefaultAzureCredential()
subscription_client = SubscriptionClient(credential)
subscription = next(subscription_client.subscriptions.list())
monitor_client = MonitorManagementClient(credential, subscription.subscription_id)

Get the current configuration for the Monitor System Updates setting using the following code:

settings = monitor_client.diagnostic_settings.list(resource_uri='/', metric_namespace='Microsoft.Insights', metric_name='Heartbeat')
for setting in settings:
    if setting.workspace_id:
        print(f"Workspace ID: {setting.workspace_id}")
        print(f"Log Analytics Solution Enabled: {setting.enabled}")

If the “Log Analytics Solution Enabled” value is False, then the Monitor System Updates setting is not enabled. To remediate this, you can enable the setting using the following code:

from azure.mgmt.monitor.models import LogAnalyticsDestinationDetails, DiagnosticSettingsCategoryResource

workspace_id = "<your workspace ID>"
log_analytics_destination = LogAnalyticsDestinationDetails(workspace_id=workspace_id)
category = DiagnosticSettingsCategoryResource(enabled=True, name='Heartbeat', destinations=[log_analytics_destination])
monitor_client.diagnostic_settings.create_or_update(resource_uri='/', settings_name='Heartbeat', parameters={'categories': [category]})

Replace <your workspace ID> with the ID of your Log Analytics workspace.

After running the remediation code, you can verify that the setting is enabled by running the code in step 3 again and checking that the “Log Analytics Solution Enabled” value is True.
