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.

Configuring Elastic Agent

For this section, we'll be spending time in the Fleet app in Kibana. As mentioned in Chapter 3, Introduction to the Elastic Stack, Fleet is a central management framework for Elastic Agent. Elastic Agent will manage integrations into the endpoint to collect targeted data, most specifically, security data.

A big benefit of Fleet is that as additional integrations are released by Elastic or the community, you can use Fleet to roll out these new features or make adjustments to existing ones.

To get to Fleet, click on the hamburger menu and then scroll down to Fleet:

Once we've clicked on the Fleet menu option, we'll be dropped onto the Fleet Overview landing page:
