Forwarder will be installed next to the data sources, and will transport and send the logs to the Logstash processors. This uses the lumberjack protocol, which is secured and requires a valid private key (.key file) and an SSL certificate (.crt file). Both Logstash forwarder and Logstash server will use these assets to secure the data transport.

To generate a valid KEY and CRT file, run the command described in listing 4-6.

Listing 4-6.Key and Certificate command line

openssl req -x509 -batch -nodes -newkey rsa:2048 -keyout lumberjack.key -out lumberjack.crt -subj /CN=localhost
