Check Text (C-248671r1015040_chk)
Note: This requirement assumes the use of the OL 8 default graphical user interface, Gnome Shell. If the system does not have any graphical user interface installed, this requirement is Not Applicable.
Verify the operating system enables a user's session lock until that user reestablishes access using established identification and authentication procedures with the following command:
$ sudo gsettings get org.gnome.desktop.screensaver lock-enabled
true
If the setting is "false", this is a finding.
Fix Text (F-52059r779578_fix)
Configure OL 8 to enable a user's session lock until that user reestablishes access using established identification and authentication procedures.
Create a database to contain the system-wide screensaver settings (if it does not already exist) with the following example:
$ sudo vi /etc/dconf/db/local.d/00-screensaver
Edit the "[org/gnome/desktop/screensaver]" section of the database file and add or update the following lines:
# Set this to true to lock the screen when the screensaver activates
lock-enabled=true
Update the system databases:
$ sudo dconf update
