Threat Hunting with Elastic Stack

5 (1)
By: Andrew Pease

Overview of this book

Threat Hunting with Elastic Stack will show you how to make the best use of Elastic Security to provide optimal protection against cyber threats. With this book, security practitioners working with Kibana will be able to put their knowledge to work and detect malicious adversary activity within their contested network. You'll take a hands-on approach to learning the implementation and methodologies that will have you up and running in no time. Starting with the foundational parts of the Elastic Stack, you'll explore analytical models and how they support security response and finally leverage Elastic technology to perform defensive cyber operations. You’ll then cover threat intelligence analytical models, threat hunting concepts and methodologies, and how to leverage them in cyber operations. After you’ve mastered the basics, you’ll apply the knowledge you've gained to build and configure your own Elastic Stack, upload data, and explore that data directly as well as by using the built-in tools in the Kibana app to hunt for nefarious activities. By the end of this book, you'll be able to build an Elastic Stack for self-training or to monitor your own network and/or assets and use Kibana to monitor and hunt for adversaries within your network.

Beats and Agents

Beats are data shippers that you can install directly on an endpoint to send data through Logstash, other data pipelines, and, of course, Elasticsearch.

They are referred to as "lightweight data shippers" and they until recently performed different functions and were all required. So, if you wanted to collect Windows event logs and network traffic from an endpoint, you had to install two different Beats: Winlogbeat and Packetbeat.

Elastic has recently released Elastic Agent, which is a framework to wrap all of these Beats together, add some new functionality, and provide the ability to centrally control the agent configurations with a Kibana app called Fleet.

There are several different Beats that all perform different functions. While there is security value in all of the Beats, we'll cover the main ones for threat hunting.


Filebeat is designed to ship files into Logstash or directly into Elasticsearch.

Filebeat uses modules that...
