Mark,
To harden our systems we used a combination of Micro$oft security
recommendations and a paper available from SANS called Securing Windows NT.

Subject: RE: Installing RealSecure Questions

Someone had mentioned that I should harden my OS before I install the
actual RealSecure software. Does anyone have any sites that I could go to
for a reference or some general tips I should consider?

The IDS should be placed behind the Firewall so it can detect anything that
might get through the firewall

Subject: Installing RealSecure Questions

I'm going to install RealSecure in our dmz network, and I was contemplating
on whether or not the IDS should be sitting outside or behind our firewall.
My objective is to monitor traffic targeting our web servers. Does anyone
have any insights on the pros and cons as to where the IDS should be placed
on the network?

I'm getting ready to install the RealSecure console and engine. Does it
matter if I do that first, then set up the machines in promiscous mode or
should I set up the machine so that it is dual-homed and then install the
console and engine software?

Also, does anyone know of any known vulnerabilities that should be fixed
before I place the IDS in a production environment? If I place the machine
outside our firewall should certain ports be disabled? Do certain ports
also
need to be diabled if the RealSecure box is sitting behind our firewall?

Sorry for the long list of questions, but any help would be appreciated.

Thanks,
Mark
