Check Text (C-271685r1091767_chk)
This requirement assumes the use of the OL 9 default graphical user interface—the GNOME desktop environment. If the system does not have any graphical user interface installed, this requirement is Not Applicable.
Verify that OL 9 disables a user's ability to restart the system with the following command:
$ grep -R disable-restart-buttons /etc/dconf/db/*
/etc/dconf/db/distro.d/20-authselect:disable-restart-buttons='true'
If the "disable-restart-button" setting is not set to "true", is missing or commented out from the dconf database files, this is a finding.
Fix Text (F-75642r1091766_fix)
Configure OL 9 to disable a user's ability to restart the system.
Add or update the [org/gnome/settings-daemon/] section of the /etc/dconf/db/local.d/00-security-settings" database file and add or update the following lines:
[org/gnome/settings-daemon/peripherals/smartcard]
disable-restart-buttons='true'
Then update the dconf system databases:
$ sudo dconf update
