How BitLocker Secures Azure Data Box Disk

What BitLocker Encryption Is

BitLocker is a native volume encryption feature developed by Microsoft that provides data protection by encrypting entire physical storage volumes using robust AES (Advanced Encryption Standard) encryption algorithms.

How It Meets the Compliance and Security Requirements

When utilizing Azure Data Box Disk, software-based disk encryption is powered by BitLocker technology:

• Protection in Transit: Every disk provided in the order is encrypted using BitLocker, ensuring that data copied onto the physical drive remains inaccessible without the authorized passkey while in transit between the customer site and the Azure datacenter.
• Passkey Protection: The disks can be unlocked using an Azure-generated passkey or a custom passkey specified during order creation, ensuring secure access during data copy.
• Cross-Platform Support: BitLocker-encrypted Data Box Disks can be connected to either Windows or Linux systems using standard USB or SATA connections.

Key Advantages and Capabilities

• Pre-configured Security: Disks arrive pre-encrypted, preventing plain-text data from ever resting unencrypted on physical storage.
• Strict Access Control: Disks require a 12-to-32 character alphanumeric passkey to unlock.
• Data Ingestion Integrity: After arrival at Microsoft datacenters, data is uploaded securely to Azure Storage and the physical disks are securely erased following NIST SP 800-88 standards.
• Zero Network Exposure: Eliminates bandwidth bottlenecks and vulnerabilities associated with public Internet data transfer.

Why This Is Optimal

BitLocker is the standard built-in software encryption mechanism for Azure Data Box Disk, requiring no additional proprietary third-party software while offering enterprise-grade encryption at rest and in transit.
