TDE meaning in Computing ?

Answer: What is Transparent Data Encryption mean?

Transparent Data Encryption (often abbreviated to TDE) is a technology employed by Microsoft, IBM and Oracle to encrypt database files. TDE offers encryption at file level. TDE solves the problem of protecting data at rest, encrypting databases both on the hard drive and consequently on backup media. It does not protect data in transit nor data in use. Enterprises typically employ TDE to solve compliance issues such as PCI DSS which require the protection of data at rest.

Microsoft offers TDE as part of its Microsoft SQL Server 2008, 2008 R2, 2012, 2014, 2016, 2017 and 2019. TDE was only supported on the Evaluation, Developer, Enterprise and Datacenter editions of Microsoft SQL Server, until it was also made available in the Standard edition for 2019. SQL TDE is supported by hardware security modules from Thales e-Security, Townsend Security and SafeNet, Inc.

IBM offers TDE as part of Db2 as of version 10.5 fixpack 5. It is also supported in cloud versions of the product by default, Db2 on Cloud and Db2 Warehouse on Cloud.

Oracle requires the Oracle Advanced Security option for Oracle 10g and 11g to enable TDE. Oracle TDE addresses encryption requirements associated with public and private privacy and security mandates such as PCI and California SB 1386. Oracle Advanced Security TDE column encryption was introduced in Oracle Database 10g Release 2. Oracle Advanced Security TDE tablespace encryption and support for hardware security modules (HSMs) were introduced with Oracle Database 11gR1. Keys for TDE can be stored in an HSM to manage keys across servers, protect keys with hardware, and introduce a separation of duties.

The same key is used to encrypt columns in a table, regardless of the number of columns to be encrypted. These encryption keys are encrypted using the database server master key and are stored in a dictionary table in the database.
