Azure security baseline for Azure Data Box

  • Artikkeli

This security baseline applies guidance from the Microsoft cloud security benchmark version 1.0 to Azure Data Box. The Microsoft cloud security benchmark provides recommendations on how you can secure your cloud solutions on Azure. The content is grouped by the security controls defined by the Microsoft cloud security benchmark and the related guidance applicable to Azure Data Box.

You can monitor this security baseline and its recommendations using Microsoft Defender for Cloud. Azure Policy definitions will be listed in the Regulatory Compliance section of the Microsoft Defender for Cloud portal page.

When a feature has relevant Azure Policy Definitions, they are listed in this baseline to help you measure compliance with the Microsoft cloud security benchmark controls and recommendations. Some recommendations may require a paid Microsoft Defender plan to enable certain security scenarios.

Note

Features not applicable to Azure Data Box have been excluded. To see how Azure Data Box completely maps to the Microsoft cloud security benchmark, see the full Azure Data Box security baseline mapping file.

Supported Enabled By Default Configuration Responsibility
True False Customer

Configuration Guidance: You can control who can access your Data Box order when the order is first created. The two roles that can be defined for the Azure Data Box service are:

Data Box Reader - have read-only access to an order(s) as defined by the scope. They can only view details of an order. They can’t access any other details related to storage accounts or edit the order details such as address and so on.

Data Box Contributor - can only create an order to transfer data to a given storage account if they already have write access to a storage account. If they do not have access to a storage account, they can't even create a Data Box order to copy data to the account. This role does not define any Storage account related permissions nor grants access to storage accounts.

To restrict access to an order, you can:

  • Assign a role at an order level. The user only has those permissions as defined by the roles to interact with that specific Data Box order only and nothing else.
  • Assign a role at the resource group level, the user has access to all the Data Box orders within a resource group.
