Threat Hunting with Elastic Stack

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.

Building an Elastic machine

In this section, we'll be building Elasticsearch and preparing it to index events from our victim machines.

We'll build Elasticsearch on CentOS. Elasticsearch can be built on Windows or macOS. However, for the lab, we're going to have everything running inside a VM.

Creating the Elastic VM

First, we need to install CentOS. Browse to the CentOS mirrors list (, select the mirror that is closest to you, and then select either the Boot or DVD ISO file. CentOS will offer you a list of mirrors that should provide the fastest download. Note that the DVD file is much larger than the Boot ISO. You can select whichever you want – the configuration steps will be the same. However, the Boot ISO requires an internet connection during configuration, while the DVD ISO does not.

Building the CentOS box follows the same steps that we used for Windows with the exception of less hard disk space...
