Access "Securing IP SANs"

Published: 19 Oct 2012

Dos and Don'ts of IP SANs The IP SAN has arrived. iSCSI enables shared, centralized storage over commodity hardware and protocols. Instead of struggling to deploy an expensive and confusing Fibre Channel (FC) SAN, more businesses are going with iSCSI-based Ethernet SANs, especially in the price-conscious Windows and Linux markets. But not everyone is happy about IP-based storage. Most potential users welcome the low price of iSCSI, but question its use for critical applications. "There are three things IP storage users worry about: speed, persistence and security," says Zophar Sante, vice president of marketing development at Sanrad Ltd., an iSCSI vendor in Menlo Park, CA. "Security is everybody's worst fear, and it's the hardest to address." The cause for concern is understandable. Even non-IT people worry about the security of public networks. Everyone knows the dangers of viruses and Trojan horses, and has heard stories about denial of service attacks that have crippled Internet resources. So it's not surprising many people believe these vulnerabilities ... Access >>>
