i'd be worried about the home fw, home router, esp if its linux ( x86
based ) ... and less worried about the windoze boxes behind the fw
-- all traffic goes out/in thru the home users fw and/or gw ...
and that's the box i'd worry about as it'd be the first point
of attack to the home lan or its dns servers
- lots of ways to get into the corp lan from the relatively
less secure "home" network
- but the corp security folks' home lan is probably
tighter than the corp lan they maintain to keep the
ceo/cfo/foo-managers happy and off the admin's back by
opening a hole here and bigger hole there because
the managers can't do their jobs due to security restraints
- and who's the one losing the laptops when on the road ??
i worked at a place where 10% - 20% of the laptops were
either stolen or "dropped and thrown away" and they want
a new laptop .. that company went "poof" in a cloud of blue
smoke
