Microsoft introduced transparent data encryption (TDE) when it released SQL Server 2008, adding full database encryption rather than the limited cell-based encryption that debuted in SQL Server 2005.

Microsoft's SQL Server database software offers two easy-to-use functions, one of which encrypts data using a passphrase, the other decrypting it with the same passphrase.

Oracle, for instance, has selective data-encryption features, and Transparent Data Encryption is available in SQL Server 2008 edition and higher.

There are several reasons why data recovery works, as below: ...

There had been one exception: Transparent Data Encryption, which encrypts SQL Server data files and backups at rest so that a database or transaction log file cannot be copied to another server ...

Third-party column-level database encryption solutions can protect columns across heterogeneous database environments that may include databases platforms like DB2, Sybase, SQL Server, and Oracle ...

Protegrity Inc. is rolling out security packages for leading databases that combine software with cryptographic hardware to provide enhanced key management capabilities.

It protects enterprise data by facilitating real-time I/O encryption and decryption of SQL Server database data. It further uses AES and 3DES encryption algorithms while encrypting and decrypting ...
