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.
Fix:
Run the following commands to disable dhcpd:
# systemctl disable isc-dhcp-server
# systemctl disable isc-dhcp-server6
Parameter:
[yes/no]
Technical Mechanism:
Run the following commands to disable dhcpd:
# systemctl disable isc-dhcp-server
# systemctl disable isc-dhcp-server6
