OL 9 /etc/gshadow- file must have mode 0000 or less permissive to prevent unauthorized access.

The "/etc/gshadow-" file is a backup of "/etc/gshadow", and as such, contains group password hashes. Protection of this file is critical for system security.

Verify that OL 9 configures the "/etc/gshadow-" file to have a mode of "0000" with the following command:

$ stat -c "%a %n" /etc/gshadow- 0 /etc/gshadow-

If a value of "0" is not returned, this is a finding.

Change the mode of the file "/etc/gshadow-" to "0000" by running the following command:

$ sudo chmod 0000 /etc/gshadow-
