Re: DMZ and critical data

I typically suggest replicating the required data to a back-end data DMZ
host. If you have to provide access to it, do it in the most secure means
possible. I could see where this would cause some issues if it has to be
updated real-time from the client, but if you approach it (as you seem to
be) with the idea of never allowing untrusted networks connect to trusted
networks, you are on the right track.
