RE: Question about dmz security

I need an opinion on a current design implementation in
place. We have
an ftp server sitting in our dmz. This box has two nics - one is
plugged into the dmz hub and one is plugged into our network. I think
this is a security risk and we should just allow internal users access
to the box via the firewall by opening the port instead of having dual
nics. they do not see a security risk. maybe i am just too
new at this
and need some education. what is the "best" way to implement this
The best way is as you suggested..
Just have one nic and force all traffic through the firewall.
That is a whole point of a DMZ. In your current setup.. if someone
compromises the ftp server they will have access to your
entire internal network without any firewall in their way.
