That's all hind sight, Harlan. Getting people to protect their servers
with basic tools like antivirus is far more feasible than trying to turn
everyone into exploit clairvoyants!
It is a very simple and indisputable fact that antivirus played a major
part in saving many very important companies a very large sum of money.
Ignoring that is not advisable.
It's irresponsible to expose a server to the Internet without antivirus
protection on it no matter what its role is.
It seems to me that there is an air of arrogance in the thought process
that says "I was able to beat it last time, so I have no worries about
the future". Many of the companies that lost millions thought that they
had all of the bases covered. Contrary to what you're trying to imply,
it was not that they were just lazier than you or less "elite". Not
every company can afford a 24/7 security geek standing at their routers
checking the exploits at the door! We can all afford basic antiviral
protection, though.
You may be patting yourself on the back because it didn't hit you this
time but it was pure luck that it was a patch that you where aware of.
Letting your guard down is such an amateur and arrogant mistake.

Yes, and all that it took to protect against Code Red
was to have disabled the .idq/.ida script mapping.
SQL Spida infected systems with blank 'sa' passwords.
SQL Slammer targetted UDP port 1434.
In all of these cases, A/V should not have been
needed, had proper administration been conducted in
the first place.
Again, the security process was broken in each case,
and installing A/V was just a band-aid.

Why did these hit your servers in the first place?
Why did you have .idq/.ida script mappings enabled?
Were they required? Why did you have a blank 'sa'
password on your SQL database server? Why were you
exposing UDP 1434 to the Internet?

Had properly and well documented procedures been
observed in the first place, A/V would not have been
necessary.
