Discussion

DHCP allows for the unauthenticated configuration of network parameters on the system by exchanging information with a DHCP server.

Check Content

Check that no interface is configured to use DHCP:

# grep -i bootproto=dhcp4 /etc/sysconfig/network/ifcfg-*

If any configuration is found, this is a finding.

Fix Text

Edit the /etc/sysconfig/network/ifcfg-* file(s) and change the "bootproto" setting to "static".
