RE: About War Driving ..

["David Gillett" <gillettdavid () fhda edu>]

  Eric didn't say *layered defence* was painting the door blue and
moving it around the side.  He said that Ansgar's view of the
measures which FatalSaint offered -- and which FatalSaint *called*
"layered defence" (calling it doesn't necessarily make it so!) --
were like painting and moving the door.

  Layered defence is an important and valuable concept.  But to be
useful, the individual layers need to actually constitute defences,
and Ansgar and Eric are saying that FatalSaint's suggestions don't
really measure up to that requirement. 

  If FatalSaint had suggested measures analogous to a guard and bars
and a dog, I don't think anyone would have argued.  The question then
is:  What measures are available to the admin of a wireless network
that are more analogous to these sorts of physical measures than the
suggestions that were offered?  (All of my authorized wireless points
are behind firewalls that filter traffic and log activity, and the
new one can triangulate client location as well.  But that's probably
out of the original poster's budget range.)
