  name: Azure Storage Private Endpoint Not Configured
  author: princechaddha
  severity: high
  description: |
    Ensure that private endpoints are configured for Microsoft Azure Storage accounts in order to allow clients and services to securely access data located over a network via an encrypted Private Link connection.
  impact: |
    Not using private endpoints for Azure Storage accounts can expose sensitive data to potential breaches by allowing data transmission over less secure networks.
  remediation: |
    Configure private endpoints for your Azure Storage accounts to ensure secure access via Private Link.
