Integrate Microsoft Defender for Cloud with Azure VMware Solution

Microsoft Defender for Cloud provides advanced threat protection across your Azure VMware Solution and on-premises virtual machines (VMs). It assesses the vulnerability of Azure VMware Solution VMs and raises alerts as needed. These security alerts can be forwarded to Azure Monitor for resolution. You can define security policies in Microsoft Defender for Cloud. For more information, see Working with security policies.

Microsoft Defender for Cloud offers many features, including:

• File integrity monitoring
• Fileless attack detection
• Operating system patch assessment
• Security misconfigurations assessment
• Endpoint protection assessment

The diagram shows the integrated monitoring architecture of integrated security for Azure VMware Solution VMs.

Log Analytics agent collects log data from Azure, Azure VMware Solution, and on-premises VMs. The log data is sent to Azure Monitor Logs and stored in a Log Analytics Workspace. Each workspace has its own data repository and configuration to store data. Once the logs are collected, Microsoft Defender for Cloud assesses the vulnerability status of Azure VMware Solution VMs and raises an alert for any critical vulnerability. Once assessed, Microsoft Defender for Cloud forwards the vulnerability status to Microsoft Sentinel to create an incident and map with other threats. Microsoft Defender for Cloud is connected to Microsoft Sentinel using Microsoft Defender for Cloud Connector.

Prerequisites

• Plan for optimized use of Defender for Cloud.

• Review the supported platforms in Defender for Cloud.

• Create a Log Analytics workspace to collect data from various sources.

• Enable Microsoft Defender for Cloud in your subscription.

  [!NOTE] Microsoft Defender for Cloud is a pre-configured tool that doesn't require deployment, but you'll need to enable it.

• Enable Microsoft Defender for Cloud.

Add Azure VMware Solution VMs to Defender for Cloud

1. In the Azure portal, search on Azure Arc and select it.

2. Under Resources, select Servers and then +Add.

   :::image type="content" source="media/azure-security-integration/add-server-to-azure-arc.png" alt-text="Screenshot showing Azure Arc Servers page for adding an Azure VMware Solution VM to Azure.":::

3. Select Generate script.

   :::image type="content" source="media/azure-security-integration/add-server-using-script.png" alt-text="Screenshot of Azure Arc page showing option for adding a server using interactive script.":::

4. On the Prerequisites tab, select Next.

5. On the Resource details tab, fill in the following details and then select Next: Tags.

   • Subscription

   • Resource group

   • Region

   • Operating system

   • Proxy Server details

6. On the Tags tab, select Next.

7. On the Download and run script tab, select Download.

8. Specify your operating system and run the script on your Azure VMware Solution VM.

View recommendations and passed assessments

Recommendations and assessments provide you with the security health details of your resource.

1. In Microsoft Defender for Cloud, select Inventory from the left pane.

2. For Resource type, select Servers - Azure Arc.

   :::image type="content" source="media/azure-security-integration/select-resource-in-security-center.png" alt-text="Screenshot showing the Microsoft Defender for Cloud Inventory page with the Servers - Azure Arc selected under Resource type.":::

3. Select the name of your resource. A page opens showing the security health details of your resource.

4. Under Recommendation list, select the Recommendations, Passed assessments, and Unavailable assessments tabs to view these details.

   :::image type="content" source="media/azure-security-integration/view-recommendations-assessments.png" alt-text="Screenshot showing the Microsoft Defender for Cloud security recommendations and assessments.":::

Deploy a Microsoft Sentinel workspace

Microsoft Sentinel provides security analytics, alert detection, and automated threat response across an environment. It's a cloud-native, security information event management (SIEM) solution that's built on top of a Log Analytics Workspace.

Since Microsoft Sentinel is built on top of a Log Analytics workspace, you'll only need to select the workspace you want to use.

1. In the Azure portal, search for Microsoft Sentinel, and select it.

2. On the Microsoft Sentinel workspaces page, select +Add.

3. Select the Log Analytics workspace and select Add.

Enable data collector for security events

1. On the Microsoft Sentinel workspaces page, select the configured workspace.

2. Under Configuration, select Data connectors.

3. Under the Connector Name column, select Security Events from the list, and then select Open connector page.

4. On the connector page, select the events you wish to stream and then select Apply Changes.

   :::image type="content" source="media/azure-security-integration/select-events-you-want-to-stream.png" alt-text="Screenshot of Security Events page in Microsoft Sentinel where you can select which events to stream.":::

Connect Microsoft Sentinel with Microsoft Defender for Cloud

1. On the Microsoft Sentinel workspace page, select the configured workspace.

2. Under Configuration, select Data connectors.

3. Select Microsoft Defender for Cloud from the list and then select Open connector page.

   :::image type="content" source="media/azure-security-integration/connect-security-center-with-azure-sentinel.png" alt-text="Screenshot of Data connectors page in Microsoft Sentinel showing selection to connect Microsoft Defender for Cloud with Microsoft Sentinel.":::

4. Select Connect to connect the Microsoft Defender for Cloud with Microsoft Sentinel.

5. Enable Create incident to generate an incident for Microsoft Defender for Cloud.

Create rules to identify security threats

After connecting data sources to Microsoft Sentinel, you can create rules to generate alerts for detected threats. In the following example, we'll create a rule for attempts to sign in to Windows server with the wrong password.

1. On the Microsoft Sentinel overview page, under Configurations, select Analytics.

2. Under Configurations, select Analytics.

3. Select +Create and on the drop-down, select Scheduled query rule.

4. On the General tab, enter the required information and then select Next: Set rule logic.

   • Name

   • Description

   • Tactics

   • Severity

   • Status

5. On the Set rule logic tab, enter the required information, and then select Next.

   • Rule query (here showing our example query)

     SecurityEvent
     |where Activity startswith '4625'
     |summarize count () by IpAddress,Computer
     |where count_ > 3
     

   • Map entities

   • Query scheduling

   • Alert threshold

   • Event grouping

   • Suppression

6. On the Incident settings tab, enable Create incidents from alerts triggered by this analytics rule and select Next: Automated response.

   :::image type="content" source="../sentinel/media/tutorial-detect-threats-custom/general-tab.png" alt-text="Screenshot showing the Analytic rule wizard for creating a new rule in Microsoft Sentinel.":::

7. Select Next: Review.

8. On the Review and create tab, review the information, and select Create.

Tip

After the third failed attempt to sign in to Windows server, the created rule triggers an incident for every unsuccessful attempt.

View alerts

You can view generated incidents with Microsoft Sentinel. You can also assign incidents and close them once they're resolved, all from within Microsoft Sentinel.

1. Go to the Microsoft Sentinel overview page.

2. Under Threat Management, select Incidents.

3. Select an incident and then assign it to a team for resolution.

   :::image type="content" source="media/azure-security-integration/assign-incident.png" alt-text="Screenshot of Microsoft Sentinel Incidents page with incident selected and option to assign the incident for resolution.":::

Tip

After resolving the issue, you can close it.

Hunt security threats with queries

You can create queries or use the available pre-defined query in Microsoft Sentinel to identify threats in your environment. The following steps run a pre-defined query.

1. On the Microsoft Sentinel overview page, under Threat management, select Hunting. A list of pre-defined queries is displayed.

   [!TIP] You can also create a new query by selecting New Query.

   :::image type="content" source="../sentinel/media/hunting/save-query.png" alt-text="Screenshot of Microsoft Sentinel Hunting page with + New Query highlighted.":::

2. Select a query and then select Run Query.

3. Select View Results to check the results.
