The shosts.equiv files are used to configure host-based authentication for 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
Verify there are no "shosts.equiv" files on the system.
Check the system for the existence of these files with the following command:
# find / -name shosts.equiv
If any "shosts.equiv" files are found on the system, this is a finding.
Fix
Remove any found "shosts.equiv" files from the system.
