The Death of Defence in Depth ? - A  rather  bold  question  that
is; is this another overhyped bloated Presentation ? Or maybe  do
we really have to rethink the way we implement Defence  in  Depth
on our networks ? This talk will hopefully give you the  answers,
if  not  at  least  the  correct  questions  to  ask  yourselves.

Over the last year [2], n.runs AG  investigated  Software that is
commonly being used in an  Defence  in  Depth  approach  and  was
quite alarmed. The number of Bugs and Design  problems  we  found
were so tremendous that we had problems dealing  with  the  shear
amount of Vendor coordination and notification emails. 

the title is misleading at best. Defense in Depth has nothing to do
with security software. To the contrary. The paradigm describes an
approach where you assume that invidual (even multiple) elements of your
defense fall, in the worst possible way (which could be code
execution). What you are describing is people adding security software
_instead_ of applying a thorough defense in depth design.

Your presentation title suggests that one of the very few paradigms
that actually promises long term security benefits does not work.
Wrong. I suggest you find a better title.
