Understanding Transparent Data Encryption

PeopleTools supports the use of Transparent Data Encryption (TDE) if you are running your database on Microsoft SQL Server 2008 (or higher). TDE provides enhanced encryption and decryption of both data files and log files through the use of database encryption files (DEK). This enables your organization to comply with numerous privacy laws, regulations, and guidelines that are required in certain industries. When implementing TDE for Microsoft SQL Server, you can apply the following AES or 3DES encryption algorithms without making any changes to your existing applications.

• AES_128

• AES_192

• AES_256

• TRIPLE_DES_3KEY

When specifying the desired encryption algorithm, make sure to enter it exactly as it appears in the list above.

While there will always be some overhead associated with any encryption processing, the performance impact introduced with TDE is minimal.

Important:

Make sure you have read and fully understand all of the Microsoft documentation related to this feature before you implement it. This PeopleTools documentation outlines PeopleTools-specific items and is not intended to replace any existing Microsoft documentation. For example, make sure you are aware of the usage recommendations and restrictions described in the Microsoft documentation as they apply also to your PeopleSoft application databases.
