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.

The Elastic Security app overview

The Elastic Security app is the central point for Elastic's security solution. It includes a security news feed, host and network data, detections, timelines, cases, and an abstracted view into the administration of the Elastic endpoint configuration.

To get to the Elastic Security app, click on the hamburger menu and select Overview under the Security heading. This landing page will show you the highlights of the events that are in the security app. From here we can jump into specific sections that show their relevant data:

You can scroll through this Overview section to get a high-level look at the different types of data that are reflected in the app. Most notably, at the bottom of the Overview page, there is a breakdown of the different datasets, separated by host and network, that we're sending into the Elastic Stack:
