I was working on scenario where company put firewalls on 6509 Cisco switches as well ASA for Internet. Main reasons were: - Two doors work better as one; breaking into the firewall on the switch means total access to the corporate network, these switches also provide routing modules, means access to all subsidiaries - People do mistake; configuration mistake on the switch firewall connected to the Internet can be dramatic Ondrej Krehel, CISSP, CEH "cableguy clueless" <cluelesscableguy To @gmail.com> pen-test () securityfocus com cc 08/11/2006 04:08 PM Subject Clueless firewall configuration ? Guys, I need to ask a favor, my boss knows nothing of IT infrastructure, and our "cableguy" (manages the firewall through a third party contract) proposed to him an architecture as follows : 2 cisco 6509 each with firewall blade in them. These function as core switches for a 1000 users site with lots of vlans and FW roules between the vlans (oh and we are a big production site that relies on these cores to let our ciritical bussiness process machines communicate to the servers). He wants to create 2 vlans, 1 for untrusted traffic and 1 vlan for DMZ machines and assign physical ports to these to connect to the internet. The DMZ vlan would also have some physical ports. These ports would not be on the core switch but on the access layer switches that are fiber attached to the distribution switches that attach to the cores... Does anyone care to comment on the security issues a setup as this would pose? would this be pentest bonanza for you guys? and what would the hackers make of a dmz vlan living in a big switch together with other vlans? I have some ideas myself, but would appreciate your take on this. I know this is the pentest list but it is you guys who get to poke holes in these designs...
