  name: Azure AKS Microsoft Entra ID Integration Not Configured
  author: princechaddha
  severity: high
  description: |
    Ensure that your Azure Kubernetes Service (AKS) clusters are integrated with Microsoft Entra ID to provide granular access to AKS resources.
  impact: |
    Without Microsoft Entra ID integration, AKS clusters might lack granular access control, increasing the risk of unauthorized access and potential security breaches.
  remediation: |
    Ensure that each Azure Kubernetes Service (AKS) cluster is configured with Microsoft Entra ID by enabling the integration in the AKS cluster settings.
