Fix Recommendation

Configure OL 8 to not allow an unattended or automatic logon to the system via a graphical user interface.

Add or edit the line for the "AutomaticLoginEnable" parameter in the [daemon] section of the "/etc/gdm/custom.conf" file to "false":

[daemon]
AutomaticLoginEnable=false

Check Contents

Note: 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.

Verify the operating system does not allow an unattended or automatic logon to the system via a graphical user interface.

Check for the value of "AutomaticLoginEnable" in the "/etc/gdm/custom.conf" file with the following command:

$ sudo grep -i automaticloginenable /etc/gdm/custom.conf

AutomaticLoginEnable=false

If the value of "AutomaticLoginEnable" is not set to "false", this is a finding.
