Hosts that run the name server software must not provide any other services. Unnecessary services running on the DNS server can introduce additional attack vectors, leading to the compromise of an organization's DNS architecture.
Verify that the BIND 9.x server is dedicated for DNS traffic. With the assistance of the DNS administrator, identify all of the processes running on the BIND 9.x server: # ps -ef | less If any of the identified processes are not in support of normal OS functionality or in support of the BIND 9.x process, this is a finding.
Disable or uninstall all non-DNS related applications from the BIND 9.x server.
