While I'm not in a large situation like this, I find myself in the too
busy to respond to everything.  Also the fact that I'm the newbie to
snort I can't really help out the complicated answers.  The majority of
the problem comes down to the fact that a lot of us that use Snort are
the same person for all network related problems and are swamped with
other issues.  I like to see both the beginner and advanced comments on
the list.  It help guides me to further my knowledge of Snort.

If you're a Troll, then I'll be Billy-Goat Gruff [0].  ;-)

No, you are.  See below.

This is the case for a some folks.  You might be surprised to find out
how
much lists like this are monitored for some little tidbit of info.

Again some.  Many of the people on this list who are willing to share
are
still around, but some have gone away.

I don't see your situation as unique--It's just a bit unusual.  For the
most part many companies don't/won't have anyone but you to handle the
security work.

There is, but it depends on you and what's good for your organization.
No
matter what people setup at their site in all reality it won't be the
'perfect' thing for you.

As for a better forum--No.  This is the beginner and advanced area.  :)

As for the answer to your problem...  Well, it's complicated.  You have
to
examine your current setup and operation to find all the faults that it
has.  You'll then need to dream up how you would like things to 'really
work'.  Sadly, reality of what you can do is somewhere in the middle of
those two.  There is no perfect solution, and there never will be.

As for ideas...  Well, here's some in no order:

	*  Layered setup
	*  Use something other than ACID (sguil [1])
	*  Use something like NetCool [2]
	*  Divide things up by 'Zones', services, or IP.

Anyway, there are tons more.  It's only limited by your imagination and
funding.  ;-)  If you're interested in specifics, let me know and I'll
explain it in more detail.

Hope that's some help!
