There must be no .shosts files on the SUSE operating system.

STIG ID: SLES-15-040020 |  SRG: SRG-OS-000480-GPOS-00227 |  Severity: high |  CCI:  | Vulnerability Id: V-234984

Vulnerability Discussion

The .shosts files are used to configure host-based authentication for individual users or 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

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

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

Fix

Text: Verify there are no ".shosts" files on the SUSE operating system.

Check the system for the existence of these files with the following command:

> sudo find / \( -path /.snapshots -o -path /sys -o -path /proc \) -prune -o -name '.shosts' -print

If any ".shosts" files are found on the system, this is a finding.
