Tutorial / Cram Notes
Microsoft Defender for SQL is a unified package for advanced SQL security capabilities. It provides a range of tools to protect SQL servers both on-premises and in Azure. When preparing for the AZ-500 Microsoft Azure Security Technologies exam, understanding how to configure Microsoft Defender for SQL is crucial. Here we’ll cover the key steps and considerations in this process.
Enabling Microsoft Defender for SQL on Azure SQL databases:
To enable Microsoft Defender for SQL on Azure SQL databases, follow these steps:
-
Access Azure Security Center:
Navigate to the Azure Portal and go to the Azure Security Center (ASC).
-
Pricing & Settings:
In ASC, select Pricing & Settings to view the list of your Azure subscriptions.
-
Choose the appropriate subscription:
Select the subscription where your Azure SQL resources are located.
-
Enable Defender for SQL:
In the settings pane, under the “Advanced Protection” settings, toggle on the Defender for SQL for Azure SQL Database and/or SQL Managed Instance options.
-
Configure SQL vulnerability assessment:
Under the “SQL Server configuration” in ASC, set up the SQL vulnerability assessment by scheduling scans and defining the storage account where the scan results will be kept.
-
Configure SQL Advanced Threat Protection:
In the threat protection settings, you can also configure SQL Advanced Threat Protection rules. This includes setting alerts for anomalous activities, detecting SQL Injection attacks, and managing data access and application change alerts.
Configuring Microsoft Defender for SQL on SQL Server on VMs:
For SQL servers running on VMs, the configuration process slightly differs:
-
Install the Microsoft Monitoring Agent (MMA):
Ensure that the MMA is installed on the SQL Server VM. This agent will transmit security data to Azure Security Center.
-
Link workspace:
Configure the MMA to report to an Azure Log Analytics workspace that is connected to Azure Security Center.
-
Enable Defender for SQL:
Within ASC, select the appropriate subscription and enable Defender for SQL for SQL servers on VMs.
-
Review the security policy:
Ensure that the Azure Defender for SQL servers on machines policy is enabled.
-
Enable vulnerability assessment:
Similar to Azure SQL databases, configure the vulnerability assessment for SQL Server on VMs, including the schedule and storage account for scan results.
-
Configure threat detection settings:
Set the threat detection settings to receive email alerts and notifications in the event of suspicious activities on your SQL Server.
Best practices and additional configurations:
-
Use Azure Policy to audit and enforce security configurations: Create and assign policies that ensure SQL databases and servers are compliant with your organization’s security standards.
-
Regularly review security alerts: Regularly check for security alerts in ASC and respond to them promptly. Use the alert details to investigate and mitigate potential threats.
-
Update and patch SQL servers regularly: Keep your SQL servers up-to-date with the latest patches to ensure protection against known vulnerabilities.
-
Limit access to SQL servers: Apply the principle of least privilege by restricting access to SQL servers to only those accounts that require it for their function.
-
Enable Multi-Factor Authentication (MFA): For administrator accounts that have access to SQL servers, enforce MFA to provide an additional layer of security.
-
Monitor with Azure Sentinel (optional): For advanced security monitoring, integrate with Azure Sentinel to view detailed security insights and utilize its Security Information and Event Management (SIEM) capabilities.
Comparison of features between Azure SQL Database and SQL Server on VM:
| Feature | Azure SQL Database | SQL Server on VM |
|---|---|---|
| Automated Security Updates | Provided by Azure | Managed by User |
| Azure Security Center Integration | Native Integration | Requires MMA Installation |
| Vulnerability Assessment | Default Capabilities Within ASC | Scheduling & Storage Configuration |
| Advanced Threat Protection | Native Alerts & Threat Detection | Customization via ASC |
| Access Management | Azure RBAC & SQL Permissions | VM Access Controls & SQL Permissions |
| Patching | Managed by Azure | Self-Managed or Automated via Toolset |
Microsoft Defender for SQL configuration is an essential topic for those aiming to pass the AZ-500 exam. Candidates should be familiar with enabling and configuring the service, the differences in settings between platforms, and adopting best practices for SQL security. The use of practical examples and hands-on experience with the Azure portal can greatly enhance your understanding and capability to apply this knowledge effectively.
