Access "Where encryption fits best"
This article is part of the Vol. 6 No. 9 November 2007 issue of RAID turns 20: Do you still need it?

A tarnished corporate name and possible financial and legal liabilities head the list of management concerns whenever removable disks and tape cartridges holding sensitive information are misplaced or stolen. Encryption can minimize the risks associated with these inevitable occurrences. But with multiple methods available to encrypt data and standards for the long-term management of encryption keys still in their early stages, companies need to proceed cautiously. Encryption secures data and makes it accessible only to those individuals or applications with the proper credentials. Companies may choose to encrypt data in a number of places in the backup infrastructure to satisfy specific application or corporate requirements.
