Verify the /run/log/journal and /var/log/journal directories are group-owned by "systemd-journal" with the following command:

$ sudo find /run/log/journal /var/log/journal -type d -exec stat -c "%n %G" {} \;
/run/log/journal systemd-journal
/var/log/journal systemd-journal
/var/log/journal/d5745ad455d34fb8b6f78be37c1fcd3e systemd-journal

If any output returned is not group-owned by "systemd-journal", this is a finding.
Fix Text (F-74695r1067180_fix)
Configure the system to set the appropriate group-ownership to the directories used by the systemd journal:

$ sudo nano /usr/lib/tmpfiles.d/systemd.conf

Edit the following lines of the configuration file:

z /run/log/journal 2640 root systemd-journal - -
z /var/log/journal 2640 root systemd-journal - -

Note: The system must be restarted for these settings to take effect.
