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.

Check Content

Verify there are no ".shosts" files on RHEL 8 with the following command:

$ sudo find / -name '*.shosts'

If any ".shosts" files are found, this is a finding.

Fix Text

Remove any found ".shosts" files from the system.

$ sudo rm /[path]/[to]/[file]/.shosts
