Implementing Transparent Data Encryption (TDE) in SQL Server Description:- Transparent Data Encryption (TDE) enables you to encrypt sensitive data that you store in tables and tablespaces. The TDE master encryption key is stored in an external security module (software or hardware keystore). We can observe whether the behavior of TDE is persistent or not after a restart. An Oracle Advanced Security license is required to encrypt RMAN backups to disk, regardless if the TDE master encryption key or a passphrase is used to encrypt the file.
