6.4 Ensure DHCP Server is not enabled - isc-dhcp-server6
Information
The Dynamic Host Configuration Protocol (DHCP) is a service that allows machines to be dynamically assigned IP addresses. *Rationale* Unless a server is specifically set up to act as a DHCP server, it is recommended that this service be deleted to reduce the potential attack surface.
Solution
Remove or comment out start lines in /etc/init/isc-dhcp-server.conf and /etc/init/isc- dhcp-server6.conf-#start on runlevel [2345]
