STIG ID: SLES-15-040030  |  SRG: SRG-OS-000480-GPOS-00227 | Severity: high |  CCI: CCI-000366

Vulnerability 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

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

Remove any "shosts.equiv" files found on the SUSE operating system.

> sudo rm /[path]/[to]/[file]/shosts.equiv
