RE: Snort Help - Network IDS

Are you using IDS? Then check out the fail open taps from intrusion.com

That would look like:

servers-switch---|
servers-switch---|---IDS-Tap---Firewall
servers-switch---|     |
                   IPS-System

This way, you can fail open on your *tap*, meaning that if it fails, all
communications can be let through. Thus, no point of failure. They even have
high-availability versions, or ones suitable for IPS.

If you have questions, feel free to mail.

Cheers,

Chris Meidinger

Subject: Snort Help - Network IDS

Recently I posted a question on different types of monitoring 
and ids setups. I have decided to go with snort and have been 
using it on a smaller network with no problem. However now, I 
need to move it to a production network which will consist of 
around a 100 servers all linked through 3com switches and 
going out through a watchgaurd firewall. I'm looking for 
different ways to implement this without setting up another 
single point of failure device which our firewall is. I'm not 
confident enough yet to risk something like that. I haven't 
found much information on packet sniffing when it comes to 
multiple entry points, found some info on wiretap, etc. but 
I've always received such great help on here I thought I 
would ask before I decided on something. Would really 
appreciate any help, I'm in a heck of a bind right now. Thanks.
