Ensure dns server services are not in use
Açıklama
The named daemon is the server for the DNS protocol and controls domain name resolution for its clients. Unless a system is specifically designated to act as a DNS server, it is recommended that the named fileset be removed to reduce the potential attack surface. Audit: the named start line in /etc/rc.tcpip must be commented out and the named subsystem must not be active.
