It's possible to have two different system share a SCSI device without
a network connection (at least under VMS). The two systems could then
access the same files and pass information that way. If you did this
none of your common network exploits would work. However; I'm sure
once the system connected to the Internet was compromised someone
would figure away to get though the SCSI channel to the protected
system. Of course the files on the first system and the shared device
would be compromised once some got in to the first system, even if
they never made it to the second.
I looked at their website, and saw a lot of smoke and mirrors about
how it works, but I'm not to sure that it is any more secure than a
normal shared device in a SCSI cluster would be. I'm also not sure a
device "switching" SCSI data is any more secure than a regular
firewall, other than it's different than normal.
THX,
Pete

Is anyone familiar with Whale Communications' Air Gap technology?
www.whalecommunications.com
They claim that there is no physical connections, no IP, yet e-commerce
applications can access the 'back office' in real time. I don't see how
that's possible if there is no physical connection. Their website isn't
very clear on how this is done, there was some alluding to the use of a SCSI
disk. My guess is that there is a shared disk subsystem between the servers
and the back office? Is this correct? If so, then doesn't that still make
a physical connection?
Thanks for your help.
