Discussion

A session lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the information system but does not want to log out because of the temporary nature of the absence. The session lock is implemented at the point where session activity can be determined. Rather than be forced to wait for a period of time to expire before the user session can be locked, OL 9 must provide users with the ability to manually invoke a session lock so users can secure their session if it is necessary to temporarily vacate the immediate physical vicinity.

Check Content

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 ability of the user to override the smart card removal action setting.

Determine which profile the system database is using with the following command:

$ grep system-db /etc/dconf/profile/user
system-db:local

Check that the removal action setting is locked from nonprivileged user modification with the following command:

Note: The example below is using the database "local" for the system, so the path is "/etc/dconf/db/local.d". This path must be modified if a database other than "local" is being used.

$ grep 'removal-action' /etc/dconf/db/local.d/locks/* 
/org/gnome/settings-daemon/peripherals/smartcard/removal-action

If the command does not return at least the example result, this is a finding.
