RHEL-08-020035 - RHEL 8.7 and higher must terminate idle user sessions.
Information
Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been left unattended.Solution
Configure RHEL 8 to log out idle sessions after 10 minutes by editing the /etc/systemd/logind.conf file with the following line:StopIdleSessionSec=600
The "logind" service must be restarted for the changes to take effect. To restart the "logind" service, run the following command:
$ sudo systemctl restart systemd-logind
