How does a physical separation of the network really help? At the end, if you can coerce the outer gatekeeper to pass information through the "gap" (by the usual BOF methods etc) you'd still have a security breach. To coerce a firewall to pass a packet between two network interfaces on the same PCI bus is the same as coercing this Whale setup to write a packet to this scsi disk (or logical device). I don't see the added protection.
I'm not an Eleet Gamer, but I've seen folks play these games where they have to pass fire, water, spikes, anvils, locked doors, and different kinds of nasty creatures. Each one requires a different trick to get past, and sometimes different tricks at different times. Similarly, different devices such as these require the crackers to learn new tricks to get past them. Or they will just stump the script kiddies. This device will foil any hacks that depend on packet makeup, because it will remove the data from the packet, and then deliver it - completely untouched, as I understand it - in new packets out the other end. Funny, I thought we already had proxy-based firewalls to do the same. Perhaps this is primarily for security officers who can understand mechanical functionality but not logical functionality. In any case, as many have said, at this point we can primarily regard it as a new toy to test, to see whether it actually does add any value. I don't have one; so if you do, and can test it and tell us something about it, please do. ;-) -- Joe Yao jsdy () cospo osis gov - Joseph S. D.
