If I understand your question, I think you're describing what Zone Labs (www.zonelabs.com/integrity) does in managing their distributed workstation firewalls. This is a vital approach since most nets have extended their perimeters to include wondering remotes. I was in the lobby of a major hotel in SF last week during RSA and watched an SE from a leading industry vendor sniffing wireless traffic from many competitors. Assuming that we've all become this causal about protecting our wondering systems, it reasonable to expect exposures from wondering PCs will only grow rapidly. It's essential that organizations look at the central management of workstation firewalls since their active management is not appropriately or adequately addressed by users.

-----Original Message----- From: Kendric [mailto:Kendric () hotpop com] Hi, just wondering if any of you guys heard of this concept of distributed firewall? I have done some research on it and found it to be quite a wonderful concept into bringing the firewall platform to each client/server end with a central management policy. In other words, it is like having a personal firewall on each individual machine, but centrally managed by a remote management console. In this way, we will not have to put any trust even on the machines on the intranet. Any comments?
I think the idea probably has some merit as part of a "defence in depth" approach. But I don't think it's sufficient on its own, because the resources that need to be protected do not exist just on the individual machines. The network which connects them -- upon which this approach DEPENDS rather heavily! -- lies outside the boundary of what can be protected this way. A network which includes both gateway firewalls and individual host security is going to be a harder nut to crack than a network that relies on only one or the other approach. And centralised administration of individual-host firewalls is an idea whose time is surely here.
