Check Text (C-257258r1069328_chk)
Note: This requirement applies to RHEL versions 8.7 and higher. If the system is not RHEL version 8.7 or newer, this requirement is not applicable.
Note: For cloud hosted systems where "ClientAliveInterval" (V-244525) is configured, this setting is not applicable.
Verify that RHEL 8 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-60884r1014792_fix)
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
