How to disable root access or root login on a RHEL system ?
Issue
- Is having a root password defined necessary? In otherwords, If I define a group of people (RedHat system administrators) with the ability to
sudo su -
to root, Do I need to have a root password defined at all in production?
Environment
- Red Hat Enterprise Linux 5
- Red Hat Enterprise Linux 6
- Red Hat Enterprise Linux 7
