Title

There must be no shosts.equiv files on the RHEL 8 operating system. (Cat I impact)

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

Fix Text

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