The Azure Policy Violation detection rule monitors Azure resources for compliance with organizational policies. When a resource is deemed non-compliant, it indicates that it fails to meet established governance requirements concerning security, networking, encryption, and other compliance areas. This rule triggers an alert when compliance checks reveal violations over a specified monitoring period, which could suggest configuration drift or security misconfigurations. The rule aids in proactive governance by enabling teams to review Azure Monitor Activity logs, assessing historical compliance data, and identifying broader trends or issues across resources.
