The root account must be the only account having unrestricted access to the OL 8 system.
An XCCDF Rule
Description
If an account other than root also has a User Identifier (UID) of "0", it has root authority, giving that account unrestricted access to the entire operating system. Multiple accounts with a UID of "0" afford an opportunity for potential intruders to guess a password for a privileged account.

A Manual Procedure
Change the UID of any account on the system, other than root, that has a UID of "0".
If the account is associated with system commands or applications, change the UID to one greater than "0" but less than "1000". Otherwise, assign a UID of greater than "1000" that has not already been assigned.
