1. What is TDE (Transparent Data Encryption) method in SQL Server?

TDE provides the ability to encrypt an entire database and to have the encryption be completely transparent to the applications that access the database. TDE encrypts the data stored in both the database’s data file (.mdf) and log file (.ldf) using either Advanced Encryption Standard (AES) or Triple DES (3DES) encryption. In addition, any backups of the database are encrypted. This protects the data while it’s at rest as well as provides protection against losing sensitive information if the backup media were lost or stolen.
