Your SAP system on Azure must comply with a regulation requiring all data at rest to be encrypted with customer-managed keys (CMK). Which combination of Azure services enforces CMK encryption for HANA data and log disks?

โœ“ Correct Answer & ExplanationHigh Availability

Correct Answer

Azure Disk Encryption (ADE) with BitLocker/dm-crypt and customer-managed keys stored in Azure Key Vault

Why This Answer Is Correct

For CMK (customer-managed keys) on managed disks: use **Server-Side Encryption (SSE) with Customer-Managed Keys** via a Disk Encryption Set referencing keys in Azure Key Vault (or Managed HSM). Alternatively, **Azure Disk Encryption (ADE)** uses OS-level dm-crypt (Linux) or BitLocker (Windows) with keys wrapped in Key Vault. For double encryption, both can be layered. HANA native Data Volume Encryption encrypts at the application layer but doesn't satisfy regulatory requirements for "encryption at rest" at the infrastructure level. PMK (platform-managed keys) means Microsoft manages the keys โ€” not compliant with CMK mandates.
