RE: Level 50

Al and others:

You ask why anyone would run on level 50?  Several reasons:

1.      Software designers who test their products at level 50 will have a much
greater
        certainty that they will run at lower security levels.

2.      A consultant who is tasked with doing the "best" job to secure a
networked computer
        certainly owes the client a duty to maximize security in a manner that 
is
con-
        sistent with the existing work environment.

3.      I sure would like somebody to prove to me that there is a "great"
performance
        degradation with level 50.  Most of our RISC clients are on 50 and they
don't
        know the difference, aside from the fact that they originally approved 
it.

I remember my days flying a corporate jet (not so long ago) and flight
instructing.  We used to make sure that all pilots from the student pilot
to the airline pilot understood the concept that they should use all
equipment available to perform a professional flight.  They owed that not
just to themselves but also to the innocent and totally trusting passengers
in the back of the airplane!

Level 50 does more parameter checking between user and system state
programs.  This will even become more important as API usage increases.  As
a consultant who has seen the damage from some wayward MI programs, this is
certainly a relatively simple use of increasing your system integrity.
