[cobalt-users] Is a firewall necessary with a RaQ?

[Rusty Wilson <rustyw007@xxxxxxxxx>]

I cant imagine how many virtual groans my subject line caused, but I'm
not an expert in this area, and I am curious...

I know what the basic purpose of a firewall is, and I understand the
different types (application/proxy, packet filtering, hybrid). What I
am wondering is...

How much *additional* security does a firewall afford over a cobalt RaQ
with only "official" (i.e. from Sun support) packages installed?

Even with a firewall, good practice dictates that you shut down all
unnecessary services on your servers (whatever they may be). My
understanding of the internet "applicance" idea is that only the
necessary services are there in the first place - so I'm not sure what
I gain by adding a firewall.

Thanks!
Rusty
