Assessment Procedure

Check Text

If the GConf2 package is not installed, this is not applicable.

To check the status of the idle screen lock activation, run the following command:

$ gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --get /apps/gnome-screensaver/lock_enabled

If properly configured, the output should be "true".
If it is not, this is a finding.
