Verify that OL 9 logs out sessions that are idle for 10 minutes with the following command:
$ sudo grep -i ^StopIdleSessionSec /etc/systemd/logind.conf
StopIdleSessionSec=600
If "StopIdleSessionSec" is not configured to "600" seconds, this is a finding.
Fix Text (F-84400r1156357_fix)
Configure OL 9 to log out idle sessions 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
