PHTN-40-000217 - The Photon operating system must configure Secure Shell (SSH) to ignore user-specific trusted hosts lists.
Information
SSH trust relationships enable trivial lateral spread after a host compromise and therefore must be explicitly disabled. Individual users can have a local list of trusted remote machines, which must also be ignored while disabling host-based authentication generally.Solution
Navigate to and open:/etc/ssh/sshd_config
Ensure the "IgnoreRhosts" line is uncommented and set to the following:
IgnoreRhosts yes
At the command line, run the following command:
# systemctl restart sshd.service
