Other Supported Logs

We include Elasticsearch ingest parsers for several log types that don’t have Elastic Agent integrations.

Example: pfSense

Security Onion includes Elasticsearch ingest parsers for pfSense firewall logs. To enable this, first go to Administration –> Configuration –> firewall –> hostgroups.


Once there, then select the syslog option and allow the traffic through the firewall.

Next, configure your pfSense firewall to send syslog to the IP address of your Security Onion box. If you are using pfSense 2.6.0 or higher, make sure that Log Message Format is set to BSD (RFC 3164, default). You should then be able to see your firewall logs using the Firewall query in Dashboards or Hunt.

Example: RITA

We include Elasticsearch ingest parsers for RITA logs. To enable this support, add the following in the relevant Salt minion pillar and then restart Elastic Agent on the minion(s):

  enabled: True

This will enable the following Elastic Agent inputs:





If you are installing Elastic Agent on a non-Security Onion node or your filenames differ, you will need to copy the Elastic Agent configuration from /opt/so/saltstack/default/salt/elastic-agent/etc/elastic-agent.yml to /opt/so/saltstack/local/salt/elastic-agent/etc/elastic-agent.yml (or modify on the non-Security Onion node in the normal Elastic Agent configuration file) and emulate the path/filename accordingly.

Once ingested into Security Onion, you should be able to search for RITA logs in Dashboards or Hunt using event.module:rita | groupby event.dataset. You should be able to see beacon, connection, and dns logs. If the value for beacon.score in a beacon record equals 1, an alert will be generated and viewable in Alerts.
