RHEL 9 STIG: RHEL-09-252070 (in versions v1 r3 through v1 r1)

Title

There must be no shosts.equiv files on RHEL 9. (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 RHEL 9 with the following command: $ sudo find / -name shosts.equiv If a "shosts.equiv" file is found, this is a finding.

Fix Text

Remove any found "shosts.equiv" files from the system. $ sudo rm /[path]/[to]/[file]/shosts.equiv
