Discussion

The "/etc/shadow" file stores password hashes. Protection of this file is critical for system security.

Check Content

Verify RHEL 10 is configured so that the "/etc/shadow" file is group-owned by "root" with the following command:

$ sudo stat -c "%G %n" /etc/shadow
root /etc/shadow

Fix Text

Configure RHEL 10 so that the group of the "/etc/shadow" file is set to "root" by running the following command:

$ sudo chgrp root /etc/shadow
