Azure Defender for SQL is a valuable tool for database admins and cloud security teams, offering protection against threats like SQL injection attacks. This post walks you through enabling Defender for SQL, investigating alerts in the Defender portal, remediating vulnerabilities, and configuring SQL audit logs for forensic investigation.
What Does Defender for SQL Detect and Cover?
Defender for SQL helps secure your Azure SQL databases by detecting potential threats such as SQL injection attacks. It provides continuous monitoring, advanced threat protection, vulnerability assessment, and data-centric auditing and alerting.
Enabling Defender for SQL
To enable Defender for SQL, navigate to the Azure portal, select your SQL server, go to Security + Vulnerability Assessment, and turn on ‘Azure Defender’.
Investigating SQL Injection Alert Details in Defender Portal
Once Defender for SQL is enabled, you can investigate SQL injection alerts in the Defender portal. Click on ‘Alerts’ and examine the details of each alert to understand the nature of the attack.
Remediating SQL Injection Vulnerabilities in Application Code
To remediate SQL injection vulnerabilities, you should apply parameterized queries to your application code. This ensures that user-supplied data is treated as literal values rather than executable commands.
Configuring SQL Audit Logs for Forensic Investigation
It’s essential to configure SQL audit logs for forensic investigation. You can set up SQL auditing to a storage account, which allows you to analyze the collected data when needed.
