Subject: Removing FIred admins

If you rely in the integrity of information in databases, I would also
advise reviewing all trigger code present in your databases and
examining how you assess the integrity of your data.  There are some
very nasty things that someone able to write code within a database
could do to make your data gradualy degrade over time (or leak).  More
broadly, assess what sorts of executable code you might be restoring
from backups as part of your data after you have reinstalled all of your
operating systems.
