The number of such incidents could be greatly reduced if regular security
audits by competent individuals were performed before shipping software. I
truly believe that many folks have it backwards: It's not the
admins of the "250,000 hosts" that need to be educated as much as it is
the (by comparison) handful of software manufacturers. Most of these
attacks are successful because the majority of people seem to run "out of
the box" configurations. This should serve to indicate that "out of the
box" is woefully inadequate(being responsible for locking down boxes on a
regular basis I can attest to that...)
