DNS honors zone transfer requests

Description:
Zone transfers contain lists that identify every computer registered with the DNS (Domain Name System) server. This information could be useful to an attacker in performing an attack.
If the source port of the DNS zone transfer request is a privileged port number (below 1024), it could indicate that another DNS server has made the request.
Consequences:
Obtain Information
Remedy:
If your DNS server should not be participating in zone transfers, configure your DNS server to prevent zone transfers. Refer to your DNS server's documentation for details.
