WWe are having a heated discussion about using VLAN's as a type of DMZ, soI am asking the experts. I prsonally like to see physical isolation; however, our network person doesn't feel there is a threat of VLAN hopping. Please let me know your opinions.
If they are new devices with up-to-date OS versions it is not very likely that attacks similar to double encapsulated 802.1q packets will succeed. On the other hand, if they are not properly configured and/or hardened, other attacks can be accomplished, like for instance, with Cisco devices, setting up a trunking if DTP settings are poorly configured (see http://yersinia.sourceforge.net for performing that attack). -- David Barroso Berrueta Not one day goes by that I don't ride, 'til the infinite, the horse of my imagination
