Information
Data from journald should be kept in the confines of the service and not forwarded on to other services.
Rationale:
IF journald is the method for capturing logs, all logs of the system should be handled by journald and not forwarded to other logging mechanisms.
NOTE: Nessus has determined that this check is not applicable to the target device as it is currently configured. Please review the benchmark to ensure target compliance.
Solution
Edit the /etc/systemd/journald.conf file and files in /etc/systemd/journald.conf.d/ and ensure that ForwardToSyslog=yes is removed.
Restart the service:
# systemctl restart systemd-journald
