Encryption - The Missing Defence Tool In Many Companies’ Security Policy
by Paul Howard - Managing Director, DISUK Limited - Thursday, 30 June 2005.
In the past encrypting data has tended to use software running on the host systems, resulting in slow and inefficient data transfer which has led to reluctance to use encryption for security. Today dedicated hardware devices are available to offload the process to inline units designed for the task. Through the use of dedicated compression and encryption engines, encryption hardware is capable of running at the full speed of modern tape drives, with little or no latency and degradation.
It is interesting to note that some companies have used their investment in security devices as a sales tool to show they are taking the best care of their customers’ data, rather than just hoping it doesn’t get lost and compromised. As insurance companies who cover business losses see the advantage of securing data, including backup tapes, we can expect insurance premiums to reflect this.
