RE: IPS vs Firewall

["Josh Mills" <JMills () cnbwaco com>]

If you put the IPS outside of the firewall then be prepared for some massive amounts of logs! I currently have a 
similar setup and just the raw number of people setting out there running nessus and other tools quickly filled my logs 
up. I have since tuned the box and now recieve a decent amount of logs but i am wondering if it still doing me any good 
in a highly tuned state? my original idea was to put it outside the firewall so i could see everything that is hitting 
the firewall, but this just isnt possible in my setup.

List,

I am to give a presentation concerning IPS vs. IDS and why we have decided 
to implement an IPS solution.  I have stuff about each of those, but my big 
problem is going to come from my LAN/WAN group.  Because I've decided to 
place the IPS outside the firewall, they have already moaned about it and I 
know they're going to bring up why we need IPS vs. Firewall.  I have stuff 
about what firewalls don't look for or do compared to IPS.

My question is, how would you go about showing that firewalls or BigIP 
routers can be attacked directly?  For those of you concidering IPS, can you 
impart any of the knowledge gained by implementing your solutions?

Many thanks,
Benny
