cyberstrikeus 6.2.5 Ensure root is the only UID 0 account (Automated)
Description
Any account with UID 0 has superuser privileges on the system.
Rationale
This access must be limited to only the default root account and only from the system console. Administrative access must be through an unprivileged account using an approved mechanism as noted in Item 5.6 Ensure access to the su command is restricted.
Audit Procedure
Run the following command and verify that only "root" is returned:
# awk -F: '($3 == 0) { print $1 }' /etc/passwd
root
Expected Result
Only "root" should be returned.
Remediation
Remove any users other than root with UID 0 or assign them a new UID if appropriate.
