NETWORK WORLD NEWSLETTER: TIM GREENE ON VPNS 11/11/04 Today's focus: VPN Consortium performs interoperability tests for storage traffic
Dear [EMAIL PROTECTED], In this issue: * Ensuring interoperability of gear used to protect storage ��traffic * Links related to VPNs * Featured reader resource _______________________________________________________________ This newsletter is sponsored by Adtran VoIP-Enabled VPN for under $500! The NetVanta 2054 from ADTRAN now features VoIP functionality along with stateful inspection firewall, IPSec VPN, and four-port Ethernet switch. This low-cost, remotely managed SOHO security solution handles Session Initiation Protocol (SIP) signaling across the firewall and preserves Diffserv marking on VoIP calls. Take a virtual tour of the NetVanta 2054! http://www.fattail.com/redir/redirect.asp?CID=87849 _______________________________________________________________ WHAT DO YOU KNOW ABOUT THE NEW DATA CENTER?

While both iSCSI and Fibre Channel are being used over IP networks as SAN protocols, both are being protected by IPSec VPN technology, according to the standards written by the IETF that describe how the protocols work. This is key for two reasons. IPSec protects the data crossing the wire via encryption. Even though many applications encrypt stored data, encrypting the encrypted data as it moves around the SAN can only make it more secure. IPSec guards against corruption of the date. By verifying that the data that arrived is the same as the data that was sent, IPSec makes sure the stored data is authentic. In addition, IPSec is used to authenticate the origin of the data to thwart attempts to spoof source IP addresses and store false data. Since IPSec is being used to support storage networks, it makes sense that the equipment imposing the IPSec protection should be interoperable. This makes it possible for customers to mix equipment from one vendor with equipment from another. Toward this end, the VPN Consortium (VPNC) is performing interoperability tests on equipment that is used to protect storage traffic from point to point. The first is Cisco's SAN-OS software, which was tested running on a SAN switch. The test certifies interoperability between vendors' gear and a VPN server maintained by the VPNC. The VPNC says it expects more SAN vendors to test their gear for VPNC basic interoperability. "Although SANs are not typically thought of when discussing VPNs, they are a part of the VPN landscape that is rapidly growing in importance." _______________________________________________________________ To contact: Tim Greene Tim Greene is a senior editor at Network World, covering virtual private networking gear, remote access, core switching and local phone companies.
