Title

Remote consoles must be disabled or protected from unauthorized access. (Cat II impact)

Discussion

The remote console feature provides an additional means of access to the system which could allow unauthorized access if not disabled or properly secured. With virtualization technologies, remote console access is essential as there is no physical console for virtual machines. Remote console access must be protected in the same manner as any other remote privileged access method.

Check Content

Check /etc/securetty # more /etc/securetty If the /etc/securetty file does not exist, or contains other than "console" or "/dev/null" this is a finding.

Fix Text

If the /etc/securetty file does not exist, create the file containing only the word console and ensure correct file properties. # echo “console” > /etc/securetty
