ArcSight doesn't do *packet-inspection* like an IDS.  It absolutely does 
depend on rules, or policies if that's what you'd rather call the series 
of criteria which must be met to fire off a correlation event.  All of 
the Arcsight engineers I've spoken to call them rules, though.

I'm also not sure why the overposter is catching such flak for asking 
about community rules.  It's certainly true that you should be getting 
training and documention on rule creation as part of your rollout, and 
it's likely true that Arcsight will give you some site specific 
rule-content as well.  It still makes perfect sense to me to look for 
community-created rules from other sites that have overlapping needs. 
There are many examples of site-agnostic rules that would be widely 
applicable... rules correlating related Emerging Threats sigs for snort 
could cut down on falses significantly and would have very little 
site-dependence.

It may be that you're looking in the wrong place.  Most of the useful 
information sharing regarding Arcsight seems to happen in the forums 
they host, which cannot be accessed without a support account.
If you don't have one, ask for one and look there.
