rsyslog will create logfiles that do not already exist on the system. This setting controls what permissions will be applied to these newly created files.
It is important to ensure that log files have the correct permissions to ensure that sensitive data is archived and protected.
Run the following command and verify that $FileCreateMode is 0640 or more restrictive:
# grep ^\$FileCreateMode /etc/rsyslog.conf
Edit the /etc/rsyslog.conf and set $FileCreateMode to 0640 or more restrictive:
$FileCreateMode 0640
See the rsyslog.conf(5) man page for more information.
You should also ensure this is not overridden with less restrictive settings in any /etc/rsyslog.d/* conf file.
