OL 9 file systems must not contain .shosts files.

Rule version OL09-00-002420 · STIG v1 · 2026-08-21

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

Verify that OL 9 has no ".shosts" files on the system with the following command:

$ sudo find / -name .shosts

If a ".shosts" file is found, this is a finding.

Fix

Remove any found ".shosts" files from the system.

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