Fix Recommendation

Configure OL 8 to enable a user's session lock until that user reestablishes access using established identification and authentication procedures.

Select/create an "authselect" profile and incorporate the "with-smartcard-lock-on-removal" feature as in the following example:

$ sudo authselect select sssd with-smartcard with-smartcard-lock-on-removal

Alternatively, the "dconf" settings can be edited in the "/etc/dconf/db/*" location.

Edit or add the "[org/gnome/settings-daemon/peripherals/smartcard]" section of the database file and add or update the following line:

removal-action='lock-screen'

Update the system databases:

$ sudo dconf update

Check Contents

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:

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.

$ sudo grep -r removal-action /etc/dconf/db/*

/etc/dconf/db/distro.d/20-authselect:removal-action='lock-screen'

If the "removal-action='lock-screen'" setting is missing or commented out from the "dconf" database files, this is a finding.
