## 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": {
  ```
* ```
     ...
  ```
* ```
   }
  ```
* }, ... } }

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/ai-and-machine-learning/appsec-azure-240.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
