ELK and OSSEC are now setup to write alerts to alerts.json, and you can use lumberjack and the json codec to feed those logs to the logstash service. Here's how: git clone https://github.com/ossec/ossec-hids.git cd ossec-hids sudo ./install.sh Follow the prompts as usual. Choose update. Or choose server if a fresh install. Once install is finished, add the jsonout_output = yes to the config at: /var/ossec/etc/ossec.conf Update the global section to include: <jsonout_output>yes</jsonout_output> Restart OSSEC: /var/ossec/bin/ossec-control restart Verify the new json file is in place: cat /var/ossec/logs/alerts/alerts.json Setup logstash-forwarder. Install as normal, then build your config at /etc/logstash-forwarder: { "network": { "servers": [ "<logstash server>:<port>" ], "timeout": 15, "ssl ca": "/etc/pki/tls/certs/logstash-forwarder.crt" }, "files": [ { "paths": [ "/var/ossec/logs/alerts/alerts.json" ], "fields": { "type": "ossec-alerts" } } ] } Restart with: /etc/init.d/logstash-forwarder restart Setup logstash to handle json files. Go to you logstash server. I assume you have installed logstash, elastic search and kibana. This is /etc/logstash/conf.d/10-default.conf on my setup. input { lumberjack { port => 10516 type => "lumberjack" ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt" ssl_key => "/etc/pki/tls/private/logstash-forwarder.key" codec => json } } output { elasticsearch { host => localhost } } Hope this helps you get setup!
