Description

Enabling Threat Detection for Azure SQL Database helps identify anomalous activities and potential security threats by alerting administrators when suspicious activity is detected. If the threat_detection_policy block is set to state = "Disabled" or omitted entirely, as in the following configuration, threat detection will not be active:

threat_detection_policy {
  state = "Disabled"
}

This increases the risk that unusual access patterns or potential SQL injection attacks go unnoticed, potentially leading to data breaches or data loss. To secure your deployment, configure the threat_detection_policy block as follows:

threat_detection_policy {
  state = "Enabled"
}

If left unaddressed, disabling this feature may allow attackers to exploit vulnerabilities in your database environment undetected.
