Filebeat and ELK stack question

Hi

I have two servers (one that is running suricata and filebeat) the other is running ELK stack. They are on the same network and I want to send the suricata logs via filebeat to the ELK stack (that as basic license and security enabled).

Do I need to configure SSL to manage this to work?

You shouldn't need to, but it's highly recommended. Once you move beyond a single node cluster you do need to set Security up by default.
