Fix Recommendation

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

Check Contents

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.
