PHTN-40-000188 - The Photon operating system must configure Secure Shell (SSH) to disallow HostbasedAuthentication.

Information

SSH trust relationships enable trivial lateral spread after a host compromise and therefore must be explicitly disabled.

Solution

Navigate to and open:

/etc/ssh/sshd_config

Ensure the "HostbasedAuthentication" line is uncommented and set to the following:

HostbasedAuthentication no

At the command line, run the following command:

# systemctl restart sshd.service
