Tutorial / Cram Notes
Microsoft Defender for Cloud, previously known as Azure Security Center, is a tool that provides unified security management and advanced threat protection across hybrid cloud workloads. When preparing for the SC-200 Microsoft Security Operations Analyst exam, understanding how to configure Microsoft Defender for Cloud is essential. Here we’ll delve into planning and configuring settings, focusing on targeting the appropriate subscriptions and workspaces.
Setting up Microsoft Defender for Cloud
To begin using Microsoft Defender for Cloud, you must first set up your account. This involves:
- Enabling Microsoft Defender for Cloud in the Azure portal.
- Selecting the subscription or subscriptions you want to monitor.
- Configuring the security policy.
Selecting Target Subscriptions
Microsoft Defender for Cloud can monitor multiple subscriptions. When selecting target subscriptions, consider the scope of your security operations and the nature of the resources within each subscription. To include a subscription:
- Navigate to Defender for Cloud in the Azure portal.
- Select ‘Environment settings’ on the sidebar.
- Choose each subscription to include and turn on the Microsoft Defender plans relevant for your resources.
Here’s an example of a simple table that highlights the consideration for subscription inclusion:
| Subscription ID | Include in Defender for Cloud | Reason |
|---|---|---|
| Subs-A-123 | Yes | Contains production workloads |
| Subs-B-456 | No | Development environment |
| Subs-C-789 | Yes | Contains critical data assets |
Configuring Workspaces
A workspace in Defender for Cloud is essentially an Azure Monitor Log Analytics workspace that collects, analyzes, and acts on telemetry data. You must connect your resources to a workspace to enable advanced threat detection capabilities. The data from the resources is sent to this workspace for analysis and storage.
To link your workspaces:
- Within Defender for Cloud, find the ‘Environment settings’ tab.
- Select the relevant subscription.
- For each resource, choose an existing workspace or create a new one.
Consider the geographic location and data sovereignty requirements when configuring workspaces:
| Workspace Name | Subscription ID | Geographic Location | Use Case |
|---|---|---|---|
| Workspace-Prod | Subs-A-123 | East US | Production telemetry |
| Workspace-Dev | Subs-B-456 | Central US | Development telemetry |
| Workspace-EU | Subs-C-789 | West Europe | GDPR Compliance |
Security Policy Configuration
Configuring your security policy is critical for compliance and maintaining good security practices. Microsoft Defender for Cloud offers a default security policy applied to all registered Azure subscriptions. This policy aligns with Azure’s best practices for security.
Custom policies can also be created and assigned using Azure Policy. Here’s how you can manage them:
- Access ‘Security Policy’ from the Defender for Cloud main menu.
- Choose a subscription or a management group, and select the appropriate policy to assign.
- If necessary, create custom initiatives and assign them for specific compliance needs.
Enabling Microsoft Defender Plans
To take full advantage of Defender for Cloud’s security capabilities, you can enable various Microsoft Defender Plans such as:
- Microsoft Defender for Servers
- Microsoft Defender for App Service
- Microsoft Defender for Storage
- Microsoft Defender for SQL
These plans can be enabled on a per-subscription basis following these steps:
- In the ‘Environment settings’ section, choose each subscription.
- Within the subscription, click on the ‘Plans on this subscription’ tab.
- Select which Defender plans you want to enable.
For example:
| Feature | Enable for Subscription Subs-A-123 | Enable for Subscription Subs-B-456 | Enable for Subscription Subs-C-789 |
|---|---|---|---|
| Defender for Servers | Yes | No | Yes |
| Defender for App Service | No | Yes | No |
| Defender for Storage | Yes | Yes | Yes |
| Defender for SQL | Yes | No | Yes |
By following the guidance above, you can effectively plan and configure Microsoft Defender for Cloud settings to ensure your Azure and hybrid cloud workloads are adequately protected. It’s essential to tailor these settings to align with your organization’s security requirements and compliance obligations. Regularly reviewing and updating these configurations ensures your security posture remains robust as your cloud environment evolves.
