Discussion

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 Content

Verify there are no "shosts.equiv" files on OL 8 with the following command: 
 
$ sudo find / -name shosts.equiv 
 
If an "shosts.equiv" file is found, this is a finding.

Fix Text

Remove any found "shosts.equiv" files from the system. 
 
$ sudo rm /etc/ssh/shosts.equiv
