| 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 |
|---|
| 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 |
