Details
Check Text (C-258077r1155659_chk)
Verify RHEL 9 logs out sessions that are idle for 10 minutes with the following command:
$ systemd-analyze cat-config systemd/logind.conf | grep StopIdleSessionSec
#StopIdleSessionSec=infinity
StopIdleSessionSec=600
If "StopIdleSessionSec" is not configured to "600" seconds, this is a finding.
Fix Text (F-61742r1155658_fix)
Configure RHEL 9 to log out idle sessions.
Create the directory if necessary:
$ mkdir -p /etc/systemd/logind.conf.d/
Create a *.conf file in /etc/systemd/logind.conf.d/ with the following content:
[Login]
StopIdleSessionSec=600
KillUserProcesses=no
Restart systemd-logind:
$ systemctl restart systemd-logind
