Storage Security Buying Guide
Data security is a problem for any size business. Better security controls, carefully regulated tape storage, and improved authentication and rights management have reduced the incidence of security faults. This buying guide lists the criteria involved in data security (encryption) initiatives to help storage administrators identify prospective encryption solutions in tape drives, software and dedicated security appliances.
Encryption appliances sit inline on a network and use specially designed electronics to encrypt data at line speeds, essentially eliminating the performance penalty imposed by encryption software running on a general server. While software-based encryption is typically handled as a specific event or process (e.g., encrypting data during a backup process), appliance-based encryption normally can handle any quantity of data in flight. This segment focuses on specific considerations for hardware-based encryption products. You'll also find a series of specifications to help you compare products from vendors.
While encrypting data "at the tape" can offer some compelling advantages, you will need to upgrade the tape drives themselves, update device drivers, change drive settings in your backup software and switch over to new media. The impact on your existing backup process can be substantial. Many organizations choose instead to implement encryption in the backup software running on a backup server. This segment of the storage security guide will focus on specific considerations for software-based encryption products.
This Buying Guide covers the major product considerations involved in data security (encryption) initiatives. Each chapter offers a set of buying points and product specifications that can help readers identify prospective new encryption products in tape drives, software, and dedicated appliances.
Encrypting data "at the tape" gives storage administrators several advantages. Tape-based encryption uses hardware on the drive itself, so encryption is fast -- it doesn't congest the backup server and slow the backup process. Once encrypted, administrators can send tapes offsite with the knowledge that their contents are secure and can help them meet regulatory obligations. This chapter focuses on specific considerations for LTO-4 tape drives. After that, you'll find a series of specifications to help make on-the-spot comparisons of products from vendors
