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.

Enabling the detection engine and Fleet

Now that we've built and configured security for Elasticsearch and Kibana, let's enable the detection engine and Fleet. The detection engine is how we'll ingest and manage the prebuilt Elastic rules for the Security app and Fleet is how we'll centrally manage collection agents.

Detection engine

The detection engine is where prebuilt detection logic is created and managed for the Security app. Detection logic, as utilized in the Security app, is alerts that are generated by certain different conditions on the endpoints. This is not things such as malware alerts, but more like "a binary is being run from the recycle bin." These rules are hand-created by contributors to the Detection Rules GitHub repository ( We'll spend more time on Detection Rules in the following chapters.

For now, we want to enable the prebuilt rules:
