Ensure DHCP Server is not enabled
The Dynamic Host Configuration Protocol (DHCP) is a service that allows machines to be dynamically assigned IP addresses.
Parameter:
[yes/no]
Technical Mechanism:
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.
Fix:
Remove or comment out start lines in /etc/init/isc-dhcp-server.conf and
/etc/init/isc-dhcp-server6.conf:
# start on runlevel [2345]
