While we impatiently wait for Packetbeat Flows to be released and allow more out-of-the-box network protocol level capture capabilities, we'll use tcpdump capture using the below command for the purpose of this blog: the above command will listen on the eth0 network interface of the monitored host and capture all and only the TCP packets indicating that a new TCP connection handshake was initiated, also avoiding resolving IP to hostnames for faster execution; then we pipe the results to netcat to send them to our Logstash instance for event processing, which we assume here to be running locally. This repository also consists of a python module that aids rule creation and unit testing. Rules run periodically and search for source events, matches, sequences, or machine learning job anomaly results You can also select up to three fields to detect a combination of new terms (for example, a host.ip and host.id that have never been observed together before).
