Control: Azure Synapse workspaces should use customer-managed keys to encrypt data at rest

Description

Use customer-managed keys to control the encryption at rest of the data stored in Azure Synapse workspaces. Customer-managed keys deliver double encryption by adding a second layer of encryption on top of the default encryption with service-managed keys.

Usage

Run the control in your terminal:

powerpipe control run terraform_azure_compliance.control.synapse_workspace_encryption_at_rest_using_cmk

Snapshot and share results via Turbot Pipes:

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

SQL

This control uses a named query:

select
  address as resource,
  case
    when (attributes_std -> 'customer_managed_key') is null then 'alarm'
    when (attributes_std -> 'customer_managed_key' -> 'key_versionless_id') is not null then 'ok'
    else 'alarm'
  end status,
  split_part(address, '.', 2) || case
    when (attributes_std -> 'customer_managed_key') is null then ' ''customer_managed_key'' not defined'
    when (attributes_std -> 'customer_managed_key' -> 'key_versionless_id') is not null then ' encrypted with CMK'
    else ' not encrypted with CMK'
  end || '.' reason
  
  , path || ':' || start_line
