Let us delve into how to configure Microsoft Defender for SQL, thereby stepping towards acing the AZ-500 Microsoft Azure Security Technologies exam.
Microsoft Defender for SQL: A Brief Understanding
Microsoft Defender for SQL is an integrated security feature for Azure, focused primarily on the security of SQL servers hosted on Azure. It is capable of providing alerts for suspicious database activities, discovering and classifying sensitive data, providing actionable recommendations to improve SQL server security, and more.
Configuration of Microsoft Defender for SQL
Step 1: Enabling Security Center Standard Tier
First, you need to upgrade your subscription to the standard tier of Azure Security Center. This can be done by navigating to the “Pricing & settings” option under Azure Security Center and choosing the subscription to be upgraded. Click on “Upgrade” and choose “Standard” for the pricing tier, and then click on “Save”.
Step 2: Data Discovery & Classification
Microsoft Defender for SQL offers a data discovery and classification feature that introduces a new set of capabilities, forming a new SQL Information Protection paradigm. Enable this feature to spot and classify sensitive data across your databases.
Navigate to SQL servers within the Azure portal. Choose the required SQL Server and select “Security” > “Advanced Data Security”. Then, under the “Data Discovery & Classification” option, click on the “Discover And Classify Now” button.
Step 3: Advanced Threat Protection
Windows Defender for SQL also provides Advanced Threat Protection (ATP), which defines a unified package for advanced SQL security capabilities. It can detect and respond to potential threats as they occur.
Under the “Advanced Data Security” settings within SQL servers in the Azure portal, there is an “Advanced Threat Protection settings” section where you can set a Notification email to get alerts, and set the “Email service and co-administrators” to “On”. Then under “Threat detection types”, select “All” to protect against all types of threats.
Step 4: Vulnerability Assessment
The Vulnerability Assessment (VA) tool in Microsoft Defender for SQL is designed to provide easy tracking of your security settings. It highlights deviations from best practices and provides clear guidance on risk mitigation.
To configure this, navigate to the “Security” → “Advanced Data Security” section under your chosen SQL Server. Ensure you have enabled the “Periodic vulnerability assessment scans” option under the “Vulnerability Assessment” settings.
Summing-up
In conclusion, Microsoft Defender for SQL provides an advanced, user-friendly framework for SQL security management, helping you guard against threats and intrusions. It complements your efforts toward the AZ-500 Microsoft Azure Security Technologies exam. Remember, each setting can be configured separately, allowing for highly customized protection tailored to your specific security needs.
