[unisog] IDS vs. Privacy

I think everyone who has posted replies has some very valid points
and suggestions, so won't reiterate that here.  :)

Maybe I am overlooking something obvious, but what exactly is this
IT management trying to protect?  "Privacy Policies" is vague.  Are
they concerned about the privacy of student data (ie a person
not authorized to know student social security numbers or health
information may see this information) or some other privacy concern?

At a place I worked at before, we had to sign forms (and so did all the
people who worked with student data).  It was more of an awareness
thing.  And not to mention it showed that the University
was trying to hold people accountable and was educating it's own
ranks about student data privacy.  If anyone did anything wrong, they
could hold them against the signed form.  I am not sure how your
data centers/server rooms are, but at my previous school they had
cameras as well that recorded who went in and out of the room and
at what time.   I am not sure if that is done here at Eastern MI; I am
not a part of the central IT ranks.

I guess I would rather hear the management's worst-case scenario
as to what they are afraid of.  Like someone said, they might be
misinformed or confused about something.  Once you get that
out in the open, try to figure out ways to prevent it with audits,
checks-and-balances, etc.  If they are afraid of their own IT staff,
maybe they would accept criminal background checks before hiring, for
example.

That is just my thoughts off the top of my head. ;)
