Information

The Dynamic Host Configuration Protocol (DHCP) is a service that allows machines to be dynamically assigned IP addresses.

Unless a system is specifically set up to act as a DHCP server, it is recommended that the dhcp package be removed to reduce the potential attack surface.

Solution

Run the following command to remove dhcp :

# yum remove dhcp
