Strong security is not a luxury anymore in today's round-the-clock, global business environment. It is a requirement. Ensuring the protection and security of an organization's information is the foundation of any successful business. Encrypting data is a key element when addressing these concerns. IBM® provides a wide range of IBM storage hardware products that are capable of encrypting the data that is written on them. This product line includes a variety of disk systems and tape drives. Several IBM storage products support encryption.

Data can be encrypted by means of special software programs, hardware adapters, facilities, or outside of the device where the data is stored. Encrypting data with software programs takes away processor power, and encrypting data with hardware requires additional investment in hardware for the computers. In addition to hardware encryption facilities, IBM disk systems and tape drives provide data encryption capabilities. This IBM Redbooks® publication explores the IBM solutions to encrypt data in the enterprise, as well as key management using the Tivoli® Key Lifecycle Manager.

This book describes IBM System Storage® data encryption. This book is intended for anyone who needs to learn more about the concepts of data encryption and the IBM storage hardware and software that enable data encryption.
