Advanced Threat Protection detects anomalous database activities indicating potential security threats to Azure Database for MySQL.

Advanced Threat Protection provides a new layer of security, which enables customers to detect and respond to potential threats as they occur by providing security alerts on anomalous database activities. Advanced Threat Protection makes it simple to address potential threats to the Azure Database for MySQL server without the need to be a security expert and integrates its alerts with Azure Security Center.

For a full investigation experience, it is recommended to use Server Logs in Azure Database for MySQL , which generates database query and error logs.
