Last week I sent a bunch of people some of my information on Cisco and ISS systems. Could someone post it here again or 
email me it. I have been getting more requests for it and I dont want to write it up all over again. I know, I should 
have saved it in the "sent mail" folder but it got deleted. Thanks in advance.

I setup a dragon solution about a year ago and it seemed like it was =
very difficult to configure when compared to all the rest of the systems =
partially because of the way you had to go online and get a license for =
each service then download a key and try to load the key and make it all =
work together. This may have all changed by now but at the time i had a =
ton of trouble getting it installed.=20

We have been using Cisco IDS systems for a number of years and recently
switched over to the new ISS Proventia Series appliances. I have worked
with both extensively and I have to say that the ISS solution is MUCH
better than the Cisco solution. Some of the big differences are that the
ISS people get out a sig about 2 weeks before Cisco even touches it.
Also, the Cisco sensors don't have a way of automatically downloading
and installing the new sigs. Its all a manual process that is a pain in
the A** Reporting is much much better and faster on the ISS as well.
There are many more advantages of going with ISS so if you need anymore
info email me. I still have all my data sheets that I did when we were
testing all the solutions.

PS - go with the inline stuff (IPS). Snort also has an inline patch
available.

I have implemented a new cisco ids solution and i am very pleased with
it! the signatures are highly tunable for a commercial package and it
seems to be pretty stable. the sensor itself runs on redhat so maybe it
isnt that much different than snort.

Hi Andy

How good can vendor independant IDS solutions (Specially Opensource)
work in an Enterprise Cisco Based network?

What do you think about Cisco IDS solutions?

Importance: Low

Hi Mat,
I was faced with the same dilemma some years back, my site below details
the various technologies you can bring to bear.  I also wrote an article
for SecurityFocus regarding deploying IDS from a vendor neutral
standpoint http://wwwsecurityfocus.com/infocus/1754

I'd suggest starting simply and building up but always keep the defence
in depth end goal in sight.  Also, don't forget that in addition to
detecting attacks you have to react to them also.  If you need further
advice offlist don't hesitate to ask.

Finally, if you go down the Network IPS route there are 2 main
varieties; rate based and content based, I refer to the former as Attack
Mitigation Systems  they fill an important role but IMHO are not IPS.
Ideally you
should have both varieties.   There are some products that claim to do
both,
but .....

take care

Hello,

I have been tasked with looking at and recommending an IDS system for=20
my company.

I have been looking at open source products (Snort) which seems to be=20
a very good system with a lot of community support. My problem is we=20
are an ASP We want connections to be able to reach our systems for=20
the services we provide. I want to be able to monitor over 100=20
internet facing servers (behind Firewalls and load balancers) and=20
alert / and possibly block non normal traffic / detected attack=20
signatures.

After doing some reading into different methods IDS v IPS, Host v=20
Network, I favour a combination, we have at anyone time up to 50,000=20
concurrent connections to our systems so I have a problem of scale.=20
One Snort box is just not going to cut it!

Looking at how I can "tap" into the network traffic has been partially

solved by using IDSVLANS which is supported by our Switch hardware.=20
(Nortel 8600) So an IDSVLAN could be setup for each of our existing=20
VLANS and a couple of load balanced IDS boxes per IDSVLAN to alert to=20
a central server to produce reports / alert / wake people up....=20
Sounds great.

Though I have not looked at it in as much detail as network based IDS,

I expect I can get a hosts based IDS to also alert (SNMP or what ever)

to a central server to again produce reports / alerts / wake people=20
up.

I am interested to here what systems you use to do IDS / IPS. Do you=20
have in place IDS systems for platforms of a larger or similar scale?=20
I would like to here from people have who have faced similar=20
challenges
