Title

There must be no shosts.equiv files on the SUSE 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

Verify there are no "shosts.equiv" files on the SUSE operating system. Check the system for the existence of these files with the following command: > sudo find /etc -name shosts.equiv If any "shosts.equiv" files are found on the system, this is a finding.

Fix Text

Remove any "shosts.equiv" files found on the SUSE operating system. > sudo rm /[path]/[to]/[file]/shosts.equiv
