You have an app that uses an Azure SQL database. You need to be notified if a SQL injection attack is launched against the database. What should you do?

Modifying Diagnostics settings collects metrics and logs, but does not inherently provide real-time threat detection and alerting for SQL injection attacks.

The SQL Health Check solution in Azure Monitor is primarily for performance optimization and configuration best practices, not for active security threat detection.

Azure Defender for SQL, part of Microsoft Defender for Cloud, provides advanced threat protection for Azure SQL databases. It continuously monitors for suspicious activities like SQL injection attempts, brute-force attacks, and anomalous database access patterns, and automatically generates security alerts upon detection.

Enabling server-level auditing records database events, which can be useful for forensics, but it does not actively detect or notify about SQL injection attacks.
