Uninstall DHCP Server Package
An XCCDF Rule
Description
If the system does not need to act as a DHCP server,
the dhcp package can be uninstalled.
The dhcp-server package can be removed with the following command:
$ sudo yum erase dhcp-server
Rationale
Removing the DHCP server ensures that it cannot be easily or accidentally reactivated and disrupt network operation.
