Ensure Only root has the UID 0
The built in root account is disabled by default and administrator users are required to use sudo to run a process with the UID '0'. If another account with UID '0' exists, this is a sign of a network intrusion or a malicious user that is attempting to circumvent security controls.
Parameter:
[yes/no]
Technical Mechanism:
To list all of the accounts with a UID of '0', run this command:
sudo dscl . -list /Users UniqueID | grep -w 0 | wc -l
If the result is not '1', this is a finding.
