Fix Recommendation

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

Check Contents

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.
