Because your data is secured by default, you don't need to modify your code or applications to take advantage of Azure Storage encryption. Azure secures your data using various encryption methods, protocols, and algorithms, including double encryption. You can use your own internal public key infrastructure (PKI) root certificate authority (CA) for point-to-site connectivity. To configure data Encryption at rest, Azure offers below two solutions : Storage Service Encryption: This is enabled by default and cannot be disabled. When server-side encryption using customer-managed keys in customer-controlled hardware is used, the key encryption keys are maintained on a system configured by the customer. For more information, see Azure Storage Service Encryption for Data at Rest. Then, only authorized users can access this data, with any restrictions that you specify. Though details may vary, Azure services Encryption at Rest implementations can be described in terms illustrated in the following diagram. May 1, 2023. The Data encryption models: supporting services table enumerates the major storage, services, and application platforms and the model of Encryption at Rest supported. Encryption at Rest is a common security requirement. Encryption at rest is designed to prevent the attacker from accessing the unencrypted data by ensuring the data is encrypted when on disk. When available a customer typically opens the Azure portal for the target subscription and resource provider and checks a box indicating, they would like the data to be encrypted. This library also supports integration with Key Vault for storage account key management. Data in a storage account is encrypted regardless of performance tier (standard or premium), access tier (hot or cool), or deployment model (Azure Resource Manager or classic). Microsoft is committed to encryption at rest options across cloud services and giving customers control of encryption keys and logs of key use. Azure encryption at rest models use envelope encryption, where a key encryption key encrypts a data encryption key. In Azure, the default setting for TDE is that the DEK is protected by a built-in server certificate. However, the Azure Storage client libraries for Blob Storage and Queue Storage also provide client-side encryption for customers who need to encrypt data on the client. You can configure Azure VPN gateways to use a custom IPsec/IKE policy with specific cryptographic algorithms and key strengths, rather than the Azure default policy sets. The Queue Storage client libraries for .NET and Python also support client-side encryption. For example: Apply a label named "highly confidential" to all documents and emails that contain top-secret data, to classify and protect this data. See, Table Storage client library for .NET, Java, and Python. We explicitly deny any connection over all legacy versions of SSL including SSL 3.0 and 2.0. Azure Storage encryption for data at rest | Microsoft Learn Microsoft Azure Encryption at Rest concepts and components are described below. In transit: When data is being transferred between components, locations, or programs, it's in transit. The storage location of the encryption keys and access control to those keys is central to an encryption at rest model. On database startup, the encrypted DEK is decrypted and then used for decryption and re-encryption of the database files in the SQL Server database engine process. Azure Data Encryption-at-Rest - Azure Security | Microsoft Learn Operations that are included involve: Taking manual COPY-ONLY backup of a database encrypted by service-managed TDE is not supported in Azure SQL Managed Instance, since the certificate used for encryption is not accessible.
