Rule version OL09-00-002538 · STIG v1 · 2026-08-21

Discussion

The "/etc/gshadow" file contains group password hashes. Protection of this file is critical for system security.

Check

Verify that OL 9 configures group ownership of the "/etc/gshadow" file with the following command:

$ stat -c "%G %n" /etc/gshadow root /etc/gshadow

If "/etc/gshadow" file does not have a group owner of "root", this is a finding.

Fix

Change the group of the file /etc/gshadow to root by running the following command:

$ sudo chgrp root /etc/gshadow
