Regarding the recent conversations about risk assessment.  I can 
offer the following quantative numbers...

I work with a gentleman named Steve Smaha who did his research paper
at UC Davis on Distributed Intrustion Detection (DIDS).  As part of the
project they wrote a network level monitor and captured Internet
traffic for 3 months.  During that time they discovered 400 network
based attachs.  After contacting many of the systems administrators
subject to the attacks they came up with a discovery rate of about 2-4%.
That is >90% of all network attacks are undiscovered.  

Hope that makes you sleep better at night.
