Well, that all makes sense. This tool that you mention below is in-house, I
take it? (I'm presuming that otherwise you'ld have mentioned it by name).

Oh, how do you use Snort then? I was getting the impression that the
accepted
way was to plunk Snort output to unified for speed and then have
barnyard decode
what it's got.

what do you mean? snort runs on its own... nothing else is needed... all
the
other tools are for correlating the alerts with the traffic and other
activities
on the network so that blocks can be initiated or dropped, infestations
can be
detected and possibly blocked while letting the infested machine's owner
know
about the infestation and other similar tasks...

in my case, i use an auto-response tool that reacts to snorts alerts...
that
tool initiates and manages automatic blocking of IPs causing alerts to be
raised
by snort... my users are taught that if they cannot get to some site or
there is
a problem downloading files, they are to ask the security team to check
and see
if the site was blocked... at that point, it is up to the security team and
management to decide if the block is proper or should be dismissed...
depending
on the situation, the user may even receive a reprimand for trying to go
to a
site that is not allowed by network policy...

aside from all of that, we use the raw pcaps and the information from the
snort
alert... we don't really need anything else at this time... no fancy
graphs, no
fancy charts and no reports... management doesn't have time for all that
muckity-muck and we're not going to give it to them anyway O:)
