| Description | ||||
| 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, RHEL 8 needs to 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 Text (C-230351r1017164_chk)
Verify the operating system enables a user's session lock until that user re-establishes access using established identification and authentication procedures with the following command:
This requirement assumes the use of the RHEL 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.
Fix Text (F-32995r792898_fix)
Configure the operating system to enable a user's session lock until that user re-establishes access using established identification and authentication procedures.
Select/Create an authselect profile and incorporate the "with-smartcard-lock-on-removal" feature with 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 lines:
removal-action='lock-screen'
Update the system databases:
$ sudo dconf update
