Check Text (C-271812r1092148_chk)
Verify that OL 9 configures group ownership of the "/etc/shadow" file with the following command:
$ stat -c "%G %n" /etc/shadow
root /etc/shadow
If "/etc/shadow" file does not have a group owner of "root", this is a finding.
Fix Text (F-75769r1092147_fix)
Change the group of the file /etc/shadow to root by running the following command:
$ sudo chgrp root /etc/shadow
