What action should be taken when noncompliant resources are detected in Azure subscriptions?

Using Azure Policy to automatically remediate noncompliant resources is the most effective course of action because it ensures a proactive and systematic approach to compliance management. Azure Policy allows organizations to define rules and effects over their resources. When a resource is identified as noncompliant, Azure Policy can not only alert administrators but also take corrective actions automatically, enforcing governance and maintaining compliance without requiring manual intervention.

This automation reduces the administrative burden and helps maintain a secure environment more efficiently. Regular manual reviews or merely alerting administrators can lead to delays in remediation, potentially increasing risks. Creating tasks in Azure DevOps does not address the immediate need for compliance remediation directly within Azure, making it less suitable for this situation. Thus, leveraging Azure Policy provides a streamlined and integrated solution to managing compliance issues effectively.
