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.
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.
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.
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.

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.
Answer: False
Explanation: Microsoft Defender for SQL is not enabled by default. It must be manually enabled on each SQL server or database.
Answer: SQL Injection attacks, Data exfiltration, Brute force login attempts
Explanation: Microsoft Defender for SQL provides advanced threat detection for activities such as SQL Injection attacks, Data exfiltration, and Brute force login attempts. It does not monitor hardware like disk failures.
Answer: False
Explanation: Microsoft Defender for SQL is designed to protect Azure SQL Database, Azure SQL Managed Instance, and Azure Synapse Analytics workloads.
Answer: Enable Azure Security Center Standard tier
Explanation: Microsoft Defender for SQL requires enabling the Standard tier of Azure Security Center to provide advanced threat protection capabilities.
Answer: True
Explanation: Alerts generated by Microsoft Defender for SQL can be reviewed in the Azure Portal under the Security Center or Defender for Cloud section.
Answer: Notifies the administrator without taking action
Explanation: Microsoft Defender for SQL detects and sends alerts for potentially harmful SQL queries but does not automatically block them or roll back transactions, leaving the decision to the administrator.
Answer: Yes
Explanation: Users need to have the appropriate Azure RBAC roles, such as the Security Admin role or a custom role with necessary permissions, to enable Microsoft Defender for SQL.
Answer: Azure Machine Learning algorithms
Explanation: Microsoft Defender for SQL uses Azure Machine Learning algorithms, as well as heuristics and behavioral analytics to detect anomalies and potentially malicious activities.
Answer: True
Explanation: Security alerts from Microsoft Defender for SQL can be integrated and exported to third-party SIEM solutions for further analysis and correlation with other security data.
Answer: Identify and remediate database vulnerabilities
Explanation: The vulnerability assessment feature of Microsoft Defender for SQL helps to identify and remediate database security holes and misconfigurations.
Answer: In real-time as threats are detected
Explanation: Microsoft Defender for SQL provides threat detection in near real-time, generating and updating alerts as potential threats are identified.
Answer: True
Explanation: Microsoft Defender for SQL can protect SQL databases in both IaaS (such as SQL Server on Azure VMs) and PaaS (such as Azure SQL Database) deployments within Azure.
