What type of encryption is used for data at rest?

The Encryption at Rest designs in Azure use symmetric encryption to encrypt and decrypt large amounts of data quickly according to a simple conceptual model: A symmetric encryption key is used to encrypt data as it is written to storage.

How to encrypt data at rest in database?

You can use Transparent Data Encryption (TDE) to encrypt SQL Server and Azure SQL Database data files at rest. With TDE you can encrypt the sensitive data in the database and protect the keys that are used to encrypt the data with a certificate.

What is the most sensible encryption method for data at rest?

The encryption of data at rest should only include strong encryption methods such as AES or RSA. Encrypted data should remain encrypted when access controls such as usernames and password fail. Increasing encryption on multiple levels is recommended.
