5.4 Ensure root login is restricted to system console (Manual)

Description

The file /etc/securetty contains a list of valid terminals that may be logged in directly as root.

Rationale

Since the system console has special properties to handle emergency situations, it is important to ensure that the console is in a physically secure location and that unauthorized consoles have not been defined.

Audit Procedure

# cat /etc/securetty

Expected Result

Only consoles that are in a physically secure location should be listed in /etc/securetty.

Remediation

Remove entries for any consoles that are not in a physically secure location.
