Introduction of TDE

Any database management system must prioritize data protection. Transparent Data Encryption (TDE), a potent feature in SQL Server 2019, enhances data security by encrypting database files while they are at rest. This article will examine TDE in SQL Server 2019, go through its benefits and drawbacks, usage situations, the authorization needed to utilize it, and installation methods, give examples, and emphasize its importance in protecting sensitive data.

We can not encrypt system databases (Master, Model, and MSDB) using TDE is not accessible

TempDB is automatically encrypted when we enable TDE for a user database. Although it cannot be explicitly encrypted, tempdb is automatically encrypted when a user database enables TDE.

TDE performs real-time I/O data and log file encryption and decryption.
