Fix Recommendation

The systemd-journald directories are by design set to 2755 mode.

If any directories are found with incorrect perms, correct them with the following command:

$ sudo find /var/log/journal -type d -exec chmod 2755 {} \;

Check Contents

Verify NixOS protects log information from unauthorized read access by implementing a mode of 2755 or less on the creation of log directories with the following command:

$ sudo find /var/log/journal -type d -perm -2755 -not -perm 2755 -printf "%p %m\n"

If any directories have a permission of greater than 2755, this is a finding.
