Paul/Bamm,
Thanks for the details. I'm working through the documentation and
*trying* my best to understand the model used.
Right now I am trying to work out what needs to be where in my
'distributed' model - I have a central mysql server which can receive
logs/alerts from a small number of snort probes.
I have added the sguil database to the mysql server.
I am shortly going to try getting the probes to log unified outout to the
sguil database. Does this mean that I no longer need to log to the snort
database, or is this still required for other things like snortreport and
base. Or do I just repoint the base config at the sguil database ?
Thanks,
David

Re: [Snort-users] Alerting in near-real-time
David,
You can easily be up and running in under ten minutes. As Bamm said, Sguil
will do most of the work for you on startup.
All you need to do is modify the configuration scripts to suit your
environment. See the install docs.
As for p0f, thats a quick install.
I wouldn't worry about SANCP for now (you will see reference to it in the
config files) you can easily add that functionality after you have seen
what Sguil has to offer.
If you have any problems you can get free premium support from the author
himself. Just visit #snort-gui on irc.freenode.net and ask for Bamm
;)

Paul,
Thanks for the reply. I have looked at sguil (following your post) and I
think it may cover what I am looking for, but the install documentation
indicates relations to lots of other packages such as NSM and p0f and
includes a lot of detail on setting up the snort install, logging to what
looks like another database (i.e. a sguil database rather than the initial
snort one which is included in the snort documentation).
I don't mind re-installing snort from scratch if necessary, but I'm trying
towork forward from an existing snort install and add this alerting
function. Do you know of any documentation covering adding sguil to an
existing install, or whether I just need the exisiting database ?
Thanks,
David

Thanks to all on the list for their help to date.
I am still trying to get my head around something which I still can't
understand in the overall snort model and I'm hoping someone can set me
straight on what I'm missing (or what I'm assuming incorrectly). I may
have
asked this to the list before, but I can't find it. Apologies if I'm
asking
the same question again.
What I have got so far . . . snort sniffs packets, matches those
packets
against rules and can log the results via a variety of output plugins to
various repositories. It can log directly to a variety of databases,
but
from an optimisation point of view it is better to use unified output,
pass
that to something like barnyard and have *it* log to the database. Net
result is that events are logged in the database. This appears to be
the
end of snorts involvement in the process from what I can see.
With the data now in the database something else needs to process it
further
if any value is to come out of the data. There are various apps such as
BASE, snortnotify, snortsnarf, etc .. . . which will either summarise
the
data and mail it out or else present it via a webpage for analysis. The
problem I'm thinking of is that this is fine for trending or where there
is
someone looking at the data to review recent traffic, but I don't see
how
this can provide any sort of near-real-time alerting.
Say for example I am happy to look through reports every morning at 0900
to
see what happened yesterday, but I *really* *really* want to get an SNMP
or
SMTP alert when rule # 3423 is triggered or the string "bad stuff" is
spotted. What do people use for this type of scenario ? I understand
that
it would probably involve running a query against the database every X
minutes and acting on the results of the query, but I can't understand
how
there aren't a set of apps out there (or at least ones I can find) that
do
this type of thing as I would have thought it was a common requirement.
