Restrict Virtual Console Root Logins

An XCCDF Rule

Description

To restrict root logins through the (deprecated) virtual console devices, ensure lines of this form do not appear in /etc/securetty:

vc/1
vc/2
vc/3
vc/4

Rationale

Preventing direct root login to virtual console devices helps ensure accountability for actions taken on the system using the root account.
