As a user not aware of many security issues since I have real work to
do and almost a life therefore not enough time to read this newsgroup
- OOPS gotta go.....  

If I recall where this began correctly the original issue concerned
mail forgery by a cracker requesting that a user change her password.
A site at which user's will naively change passwords based on an
e-mail message has not kept up on enlightenment of the users.  Any
user should verify such a message in some way before acting on it.

Naive users may be a system administrators worst security risk.  By
following this track it seems obvious that sys admins may consider
more layers of faulty security code the right thing.  As a user at my
company I feel obliged to poke my head out of the foxhole to see if
someone is coming, once in a while, at least.  When "funny" things
happen here the system administration is informed.  The administrators
need to have the experience to recognize which curiousities show the
greatest potential for revealing security holes.

There is more than one benefit to teaching users to "pester" root
about unexpected occurrences.  The "funny" things users notice which
are not the result of unauthorized access are likely to be the result
of user errors.  Less user errors mean more productive systems which
means sys admins get raises, right?  Well, in a perfect world ....

Make your users your allies.

If your users know how the box is supposed to act they can tell you
when it isn't doing what it should which ~might~ help flag
impropriety.  If the box (user activities included) is acting as it is
supposed to act isn't the sys admin doing 90% of her job right,
anyway?  That additional 10% as deputy sheriff is just to prove you
hate those bad guys, anyway.  In the U.S. isn't the FBI supposed to
keep the lines free from wiretaps and the like (with all of us good
citizens' help, of course)?  If you have significant security risks,
e.g. interpol records, what the Henry Ford are you doing on publicly
accessible nets?  IMHO
