There must be no ".shosts" files on The TOSS operating system.

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.

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

$ sudo find / -name '*.shosts'

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

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

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