The workspace will validate its access to the new key vault and all data in the workspace will be re-encrypted with the new key.Electronic healthcare record data have been used to study risk factors of disease, treatment effectiveness and safety, and to inform healthcare service planning. If you choose a key in a different key vault from the ones previously used, grant the workspace-managed identity "Get", "Wrap", and "Unwrap" permissions on the new key vault. Here too, you can choose a new key using a key identifier or select from Key Vaults that you have access to in the same region as the workspace. You can change the customer-managed key used to encrypt data from the Encryption page in the Azure portal. Manage the workspace customer-managed key As previously noted, the key vault must have purge protection enabled for activation to succeed.
Once the activation completes successfully, your workspace is ready to use with the assurance that all data in it's protected with your customer-managed key. Grant the workspace managed identity access to the key vault and select the activation link in the workspace Azure portal banner. For example, you can only create a new dedicated SQL pool once activation succeeds. The workspace must be activated before you can fully use all functionality. If you do not configure a user-assigned managed identity to access customer managed keys during workspace creation, your workspace will remain in a "Pending" state until activation succeeds.
This phased approach to workspace activation ensures that data in the workspace is encrypted with the customer-managed key. The workspace managed identity must be granted the permissions it needs on the key vault before the workspace can be activated. When granting permissions via an Azure Key Vault access policy, choose the "Application-only" option during policy creation (select the workspaces managed identity and do not add it as an authorized application). The keys are made accessible to the workspace either through an access policy or Azure Key Vault RBAC. The Azure Synapse encryption model with customer-managed keys involves the workspace accessing the keys in Azure Key Vault to encrypt and decrypt as needed. The configuration setting for double encryption cannot be changed after the workspace is created.
Learn more about how encryption is used in Microsoft Azure in the Azure Encryption Overview. By default, Azure Disks, and data in Azure Storage accounts are automatically encrypted at rest. The first layer of encryption for Azure services is enabled with platform-managed keys. This key is safeguarded in your Azure Key Vault, which allows you to take ownership of key management and rotation. Azure Synapse Analytics offers a second layer of encryption for the data in your workspace with a customer-managed key. Double encryption of data at rest mitigates threats with two, separate layers of encryption to protect against compromises of any single layer.
