Impact

This rule detects whether an Azure Synapse Workspace is encrypted with a CMK. Ensuring encryption with a CMK is crucial because it grants organizations greater control over the encryption keys used to protect their data. Using a CMK enhances security by allowing key rotation, revocation, and the ability to use an organization's own key management policies. This strengthens data protection within the Synapse Workspace. Unencrypted Synapse Workspaces pose a significant security risk. Sensitive data stored and processed within them is potentially exposed to unauthorized access and data breaches.

How to Fix

Resource: Microsoft.Synapse/workspaces

• Arguments: encryption

In this example, an encryption property is added within the Microsoft.Synapse/workspaces resource definition of the JSON template. This encryption property will house the configuration for the CMK, significantly enhancing data security within the workspace. [source,go]

{ "type": "Microsoft.Synapse/workspaces", ... "properties": {

• "encryption": {

•  "cmk": {

•    ...

•  }

• }, ... } }
