Azure Data Box Disk security and data protection

This article describes the Azure Data Box Disk security features that help protect each of the Data Box solution components and the data stored on them.

Data flow through components

The Microsoft Azure Data Box solution consists of four main components that interact with each other:

  • Azure Data Box service hosted in Azure – The management service that you use to create the disk order, configure the disks, and then track the order to completion.
  • Data Box Disks – The physical disks that are shipped to you to import your on-premises data into Azure.
  • Clients/hosts connected to the disks – The clients in your infrastructure that connect to the Data Box disk over USB and contain data that needs to be protected.
  • Cloud storage – The location in the Azure cloud where data is stored. This is typically the storage account linked to the Azure Data Box resource that you created.

The following diagram indicates the flow of data through the Azure Data Box Disk solution from on-premises to Azure.

Security features

Data Box Disk provides a secure solution for data protection by ensuring that only authorized entities can view, modify, or delete your data. The security features for this solution are for the disk and for the associated service ensuring the security of the data stored on them.

Data Box Disk protection

The Data Box Disk is protected by the following features:

Hardware encrypted disks Software encrypted disks
AES 256-bit hardware encryption engine
  • BitLocker AES-128 bit encryption for the disk at all times
  • Secure update capability for the disks
  • Disks are shipped in a locked state and can only be unlocked via a Data Box Disk unlock tool. The unlock tool is available in the Data Box Disk service portal.
  • Data Box Disk data protection

    The data that flows in and out of Data Box Disk is protected by the following features:

    • BitLocker encryption of data at all times.
    • Secure erasure of data from disk once data upload to Azure is complete. Data erasure is in accordance with NIST 800-88r1 standards.

    Data Box service protection

    The Data Box service is protected by the following features.

    • Access to the Data Box Disk service requires that your organization has an Azure subscription that includes Data Box Disk. Your subscription governs the features that you can access in the Azure portal.
    • Because the Data Box service is hosted in Azure, it is protected by the Azure security features. For more information about the security features provided by Microsoft Azure, go to the Microsoft Azure Trust Center.
    • The Data Box Disk stores disk passkey that is used to unlock the disk in the service.
    • The Data box Disk service stores order details and status in the service. This information is deleted when the order is deleted.
