Practical Threat Intelligence and Data-Driven Threat Hunting

By: Valentina Costa-Gazcón

Overview of this book

Threat hunting (TH) provides cybersecurity analysts and enterprises with the opportunity to proactively defend themselves by getting ahead of threats before they can cause major damage to their business. This book is not only an introduction for those who don’t know much about the cyber threat intelligence (CTI) and TH world, but also a guide for those with more advanced knowledge of other cybersecurity fields who are looking to implement a TH program from scratch. You will start by exploring what threat intelligence is and how it can be used to detect and prevent cyber threats. As you progress, you’ll learn how to collect data, along with understanding it by developing data models. The book will also show you how to set up an environment for TH using open source tools. Later, you will focus on how to plan a hunt with practical examples, before going on to explore the MITRE ATT&CK framework. By the end of this book, you’ll have the skills you need to be able to carry out effective hunts in your own environment.

Atomic hunting with Atomic Red Team

We talked about Red Canary's Atomic Red Team in Chapter 6, Emulating the Adversary. Just to refresh your memory, Atomic Red Team is an open source project to carry out scripted atomic tests on an organization's defenses. Atomic Red Team is also mapped to the MITRE ATT&CK™ framework and offers extensive coverage of the framework's techniques.

In this section, we are going to use atomic tests to learn how to execute tests, collect evidence from our ELK/HELK instance, and develop simple detections. Atomic Red Team is a very useful tool to learn what is normal within your organization and to measure and improve visibility. A lack of the right visibility could lead to a false sense of security. It's not that uncommon that an organization believes that "such things [incidents] do not happen here," just because they do not have the right tools to "see" them happening.
