Title

There must be no .shosts files on RHEL 9.

Control

Verify there are no ".shosts" files on RHEL 9 with the following command: $ sudo find / -name .shosts If a ".shosts" file is found, this is a finding.

Discussion

The .shosts files are used to configure host-based authentication for individual users or the system via SSH. Host-based authentication is not sufficient for preventing unauthorized access to the system, as it does not require interactive identification and authentication of a connection request, or for the use of two-factor authentication.

Fix

Remove any found ".shosts" files from the system. $ sudo rm /[path]/[to]/[file]/.shosts
