Just for grins & giggles I installed this off of the iso image supported
by http://www.boseco.com/. It was very straight forward but I found the
applicationst that are integrated are poorly documented. By that I mean
that the way they are configured and integrated are poorly documented
not that the base application (such as ntop) is poorly documented. I
had to do a lot of digging to find the configuration files because they
were not always in the same places. I've done all of my testing off of
a single install so far. What I was most impressed with was the simple
configuration for vulnerability assessment scans and the basic interface
for reviewing vulnerability assessment results.
I could not find any documentation on the installation of the software
on a "sensor" only install. Does anyone have a reference for that by
chance? I don't think that it requires a full install does it?

Hello Syn Ack,
I've deployed OSSIM in four datacenters now. I think OSSIM is a good IPS
support tool, but I wouldn't deploy it as my primary IDS unless I had a
zero dollar budget for the project. OSSIM can be customized, configured
and tweaked to provide reliable and sustainable network protection, but
it requires a lot of configuration, and then a lot of tuning and
constant updating.
The Cisco ACL creation and PIX firewall rule insertion features are what
I spent the most time on. The basic functionality for attack blocking is
already there, but you'll want to make sure that a DDoS attack (or other
spoofed attack) does not cause you to ACL / firewall your network
against the entire internet.
OSSIM is a good, solid security tool. My only caution to you would be:
Make sure you have plenty of coffee in the break room, and be prepared
to spend several late nights tweaking and tuning.
OSSIM and AAnval seem to be the best "free" NETSEC tools right now.
If you have slightly more than $0.00 to spend on your IPS project, you
may want to consider Sentarus by Demarc. (www.demarc.com) The Sentarus
appliance and host agents are heavyweight contenders with Tipping Point
and ISS. They do, however, actually want customers to pay for the
software. :)
I may still have some OSSIM configs laying around that could help you
with the Catalyst ACL's and PIX firewall rules. Let me know if you want
them, and I'll start looking.
Good Luck with OSSIM !

Hello list members,
I'm working on implementing IDSes in the company a work for. Did some
of you have experience with Ossim (http://www.ossim.net)?
Any comment are welcome.
