I have an existing split DNS configuraiton.
Internal DNS devices serve my AD environmnet.
In the past I heard about additional security configuration I could do in
order to make DNS queries between intenal and external DNS more solid. I
have a firewall between internal and external DNS servers.
There is little or no security for queries in DNS.
There CAN be security for dynamic updates.
Most DNS security is done by POSITIONING the DNS
server within a firewall, or perhaps by having it only
respond to requests on a single NIC if it has more than
one.
If you know what would be a good implementation security wise please let
me know.
Likely you will need to ask a more specific question
for us to give you some idea of your options on that
a specific issue or problem.
