# Azure Databricks Workspaces not using customer-managed key for root DBFS encryption misconfiguration

## Impact

This rule checks whether Databricks Workspaces leverage a customer-managed key for root DBFS encryption. DBFS (Databricks File System) is the distributed file system used by Databricks clusters. Encrypting the root DBFS adds an extra layer of security, ensuring that even in the event of unauthorized access, the data remains inaccessible and secure. Customer-managed keys enhance security by giving you control over encryption, strengthening your security posture.

## How to Fix

*Resource:* Microsoft.Databricks/workspaces

* *Arguments:* prepareEncryption/value

## Set the `customer_managed_key_enabled` attribute to `true` during Azure Databricks workspace creation. This enables customer-managed key encryption for your DBFS root data at rest. \[source,go]

"resources": \[ { "type": "Microsoft.Databricks/workspaces", "properties": { ... "parameters": { "prepareEncryption": {

* ```
       "value": true
    },
  ```
* ```
     "encryption": {
  ```
* ```
       "value": {
  ```
* ```
         ...
  ```
* ```
       }
    },
  }
  ```

  } } ]

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/ai-and-machine-learning/appsec2-azure-48.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
