Discussion

Limiting the root account direct logins to only system consoles protects the root account from direct unauthorized access from a non-console device.

Check Content

Check /etc/securetty
# more /etc/securetty
If the file does not exist, or contains more than "console" or a single "tty" device this is a finding.

Fix Text

Create if needed and set the contents of /etc/securetty to a "console" or "tty" device.
# echo console > /etc/securetty
or
# echo ttyS0 > /etc/securetty
