Check Text (C-281282r1166798_chk)

Note: This requirement assumes the use of the RHEL 10 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 RHEL 10 prevents a user from overriding settings a blank screensaver with the following command: $ gsettings writable org.gnome.desktop.screensaver picture-uri false If "picture-uri" is writable, and the result is "true", this is a finding.

Fix Text (F-85748r1166797_fix)

Configure RHEL 10 to prevent a user from overriding the picture-uri setting for graphical user interfaces. Note: The example below is using the database "local" for the system. If the system is using another database in "/etc/dconf/profile/user", the file should be created under the appropriate subdirectory. Update the "/etc/dconf/db/local.d/00-security-settings" file to prevent a user from overriding the "picture-uri" setting: $ sudo vi /etc/dconf/db/local.d/00-security-settings [org/gnome/desktop/screensaver] picture-uri='' Update the "/etc/dconf/db/local.d/locks/00-security-settings-lock" file to prevent a user from modifying the lock applied to the "picture-uri" setting: $ sudo vi /etc/dconf/db/local.d/locks/00-security-settings-lock /org/gnome/desktop/screensaver/picture-uri Update the dconf system databases: $ sudo dconf update
