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.

Chapter 2: Hunting Concepts, Methodologies, and Techniques

Threat hunting is the combination of identifying adversary activity when automated defenses have either not detected malicious events or, more commonly, have not attributed events as being malicious.

Threat hunting commonly refers to the tactical benefit of, while I find this a lazy description, detecting "unknown unknowns." Isn't that the point of, well, everything? I don't think there are any professionals, irrespective of their vertical, that just want to do the "known knowns." While this book will focus primarily on levering the Elastic Stack to perform threat hunting, this chapter is intended to introduce threat hunting theory and concepts, to apply the proper mindset for threat hunting that will be put into practice throughout the book. This chapter, and this book, aren't intended to be an all-inclusive manual on threat hunting as a higher-level skill.

In this chapter, we'll...
