Transparent Data Encryption

What Does Transparent Data Encryption Mean?

Transparent Data Encryption (TDE) is an industry methodology that encrypts database files at the file level. Microsoft, Oracle and IBM offer Transparent Data Encryption for certain types of database systems. Transparent Data Encryption helps stored files to be resistant to access if they are stolen by a third party.


Techopedia Explains Transparent Data Encryption

Transparent Data Encryption encrypts and decrypts data with real-time I/O. Using a database encryption key in the database boot record, Transparent Data Encryption helps to implement compliance with security standards. It is important to note that while Transparent Data Encryption provides effective encryption and protection for database files, it does not provide protection for either data in use or data in transit. Stakeholders must look at different security planning for protecting data in communicational channels.

The Transparent Data Encryption architecture creates a certificate for the database encryption key that must be present for restoring backups.
