I think the real point here is that the majority of people responsible
for security have a backwards mindset.  Most security practitioners
still don't make the assumption that everything is vulnerable and
design around it.  Of course IIS is vulnerable to an unpublished 0day.
 Maybe somebody already found it or maybe it'll happen next week.

When you start with the assumption that every application and device
has major holes that haven't been discovered or disclosed you create a
totally different architecture than when you assume it's good until
proven bad.

In this case I somewhat agree with Dave - assume that your opponent is
smarter, more persistent and more creative than you could ever be.
What would you do different?

Would patching known vulnerabilities in thousands of end user desktops
be your #1 priority or would you devote more time to creatively
protecting your most valuable assets?
