The Dynamic Host Configuration Protocol (DHCP) is a service that allows machines to be dynamically assigned IP addresses.
Rationale:
Unless a system 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 command to disable dhcp # systemctl --now disable isc-dhcp-server
Parameter:
[yes/no]
Technical Mechanism:
Run the following command to disable dhcp # systemctl --now disable isc-dhcp-server
