Summary
In this module, you implemented Microsoft Defender for Databases to provide threat detection and vulnerability assessment for Contoso Financial Services' Azure SQL resources. You explored the two Defender plans—Defender for Azure SQL Databases and Defender for open-source relational databases—and enabled both at subscription scope with Azure Policy enforcement. You configured vulnerability assessment using express configuration, set baselines for accepted findings, and identified high-severity vulnerabilities for remediation. Finally, you configured alert routing to email notifications and Microsoft Sentinel, created suppression rules for known patterns, and validated end-to-end coverage with sample alerts.
With this module complete, Contoso Financial Services now has database security across all three layers: platform-level security with Microsoft Entra authentication and encryption. Plus a compliance layer with tamper-resistant audit trails, and an active threat detection layer that identifies SQL injection attempts, anomalous access patterns, and vulnerability exposures. The security operations team now receives real-time alerts for database threats, enabling rapid response to emerging security incidents.
