Implementing Transparent Data Encryption

This section provides an overview and discusses how to enable Transparent Data Encryption (TDE).

Important! PeopleTools has not introduced any functionality for TDE with respect to Microsoft SQL Server; PeopleTools only supports the use of it. You should always refer to your Microsoft Documentation for any issues with respect to TDE for Microsoft SQL Server.

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.

Enabling Transparent Data Encryption

To enable TDE:

  1. Create a master key.

  2. Create or obtain a certificate protected by the master key.

  3. Create a database encryption key and protect it by the certificate.

  4. Set the database to use encryption.

The following example illustrates encrypting and decrypting the TDEPT85X database using a certificate installed on the server named PeopleToolsEncryptCert.

USE master;
GO
/* Create Master Key Using a strong password. */
CREATE MASTER KEY ENCRYPTION BY PASSWORD = '<UseStrongPasswordHere>';
go
/* Create a PeopleTools Encryption Certificate. *?/
CREATE CERTIFICATE PeopleToolsEncryptCert 
WITH SUBJECT = 'PeopleTools Encrypt Certificate';
go
USE TDEPT85X;
GO
/* Create Database Encryption Key Using PeopleTools Encryption Certificate. */
CREATE DATABASE ENCRYPTION KEY
WITH ALGORITHM = AES_128
ENCRYPTION BY SERVER CERTIFICATE PeopleToolsEncryptCert;
GO
/* Enable Database Encryption. */
ALTER DATABASE TDEPT85X
SET ENCRYPTION ON;
GO

Note: When implementing TDE, all files and filegroups in the database are encrypted. If any filegroups in a database are marked read only, the database encryption operation will fail.
