Rule version OL09-00-002536 · STIG v1 · 2026-08-21

Discussion

The "/etc/group" file contains information regarding groups that are configured on the system. Protection of this file is important for system security.

Check

Verify that OL 9 configures the "/etc/group" file to have a mode of "0644" or less permissive with the following command:

$ stat -c "%a %n" /etc/group 644 /etc/group

If a value of "0644" or less permissive is not returned, this is a finding.

Fix

Change the mode of the file "/etc/group" to "0644" by running the following command:

$ sudo chmod 0644 /etc/group
