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 1: Introduction to Cyber Threat Intelligence, Analytical Models, and Frameworks

Generally speaking, there are a few "shiny penny" terms in modern IT terminology – blockchain, artificial intelligence, and the dreaded single pane of glass are some classic examples. Cyber Threat Intelligence (CTI) and threat hunting are no different. While all of these terminologies are tremendously valuable, they are commonly used for figurative hand-waving by marketing and sales teams to procure a meeting with a C-suite. With that in mind, let's discuss what CTI and threat hunting are in practicality, versus as umbrella terms for all things security.

Through the rest of this book, we'll refer back to the theories and concepts that we will cover here. This chapter will focus a lot on critical thinking, reasoning processes, and analytical models; understanding these is paramount because threat hunting is not linear. It involves constant adaption with a live adversary on the other side of the keyboard. As hard as you are working to detect them, they are working just as hard to evade detection. As we'll discover as we progress through the book, knowledge is important, but being able to adapt to a rapidly changing scenario is crucial to success.

In this chapter, we'll go through the following topics:

  • What is cyber threat intelligence?
  • The Intelligence Pipeline
  • The Lockheed Martin Cyber Kill Chain
  • Mitre's ATT&CK Matrix
  • The Diamond Model
