Control: Storage account encryption scopes should use customer-managed keys to encrypt data at rest

Description

Use customer-managed keys to manage the encryption at rest of your storage account encryption scopes. Customer-managed keys enable the data to be encrypted with an Azure key-vault key created and owned by you. You have full control and responsibility for the key lifecycle, including rotation and management.

Usage

Run the control in your terminal:

powerpipe control run terraform_azure_compliance.control.storage_account_encryption_scopes_encrypted_at_rest_with_cmk

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe control run terraform_azure_compliance.control.storage_account_encryption_scopes_encrypted_at_rest_with_cmk --share

  case
    when name in (select split_part((attributes_std ->> 'storage_account_id'), '.', 2) from terraform_resource where type = 'azurerm_storage_encryption_scope' and (attributes_std ->> 'source') = 'Microsoft.KeyVault') then 'ok'
    else 'alarm'
  end status,
  split_part(address, '.', 2) || case
    when name in (select split_part((attributes_std ->> 'storage_account_id'), '.', 2) from terraform_resource where type = 'azurerm_storage_encryption_scope' and (attributes_std ->> 'source') = 'Microsoft.KeyVault') then ' encrypted with CMK'
    else ' not encrypted with CMK'
