I am new to ELK, and currently implementing a SIEM using the ELK stack alongside a pfsense firewall with suricata.
The ELK stack is set up, pfsense with suricata also. I can send and visualize the firewall logs on kibana (pretty easily), but not the suricata ones. I'd like to use filebeat to ship suricata's logs to logstash and etc. but can't get a hand on an up to date version of filebeat (7.2) for freebsd as elastic doesn't support this OS. However, I found an old filebeat pkg for freebsd : version 6.7.1.
Is it possible to run the latest versions of the ELK (7.2) with filebeat 6.7.1 or should i downgrade my stack to the same version?
Or, is there a way to make filebeat pkg for freebsd using a linux one (deb or rpm)?
Or perhaps should I find an other way to ship my suricata's logs to ELK not using filebeat?
Thanks for your answers
