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.

What is threat hunting?

Before we look at the definition of threat hunting, let's clarify some misconceptions around the concept by stating what threat hunting is not. First of all, threat hunting is not the same as cyber threat intelligence (CTI) or incident response (IR), although it can be deeply related to them. CTI can be a good starting point for a hunt. IR could be the next step the organization follows after a successful hunt. Threat hunting also isn't about installing detection tools, although it can be useful to improve their detecting capabilities. In addition, it is not searching for IoCs in the organization's environment; instead, you will be looking for things that bypassed the detection systems that have been fed with IoCs. Threat hunting is not the same as monitoring either, nor running queries randomly on monitoring tools. But, most of all, threat hunting is not a task that can be performed only by a select group of experts. Of course, expertise matters...
