Fix Recommendation

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, the UID should be changed to one greater than "0" but less than "1000". Otherwise, assign a UID of greater than "1000" that has not already been assigned.

Check Contents

Verify only the "root" account has a UID "0" assignment using the following command:

$ awk -F: '$3 == 0 {print $1}' /etc/passwd

root

If any accounts other than "root" have a UID of "0", this is a finding.
