Fix Recommendation

Configure RHEL 9 to enable a user's session lock until that user re-establishes access using established identification and authentication procedures.

Select or 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.

Add or update the [org/gnome/settings-daemon/peripherals/smartcard] section of the /etc/dconf/db/local.d/00-security-settings" database file and add or update the following lines:

[org/gnome/settings-daemon/peripherals/smartcard]
removal-action='lock-screen'

Then update the dconf system databases:

$ sudo dconf update

Check Contents

Note: This requirement assumes the use of the RHEL 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 RHEL 9 enables a user's session lock until that user reestablishes access using established identification and authentication procedures with the following command:

$ gsettings get org.gnome.settings-daemon.peripherals.smartcard removal-action

'lock-screen'

If the result is not 'lock-screen', this is a finding.
