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.

Summary

So, before diving into the hunting activity itself, there's a lot of thinking and processes that must be done. In this chapter, we learned about what threat hunting is, as well as the different approaches that can be taken to implement it. We also learned what skills a good threat hunter needs and how to create an effective hypothesis, which is the crucial step of any threat hunting process. There are a few concepts we should always keep in mind: first, assume there will be a breach; second, the threat hunting team needs to know the organization's environment to be able to detect anomalies; and third, after carrying out a successful hunt, automate the process as much as possible. Establish a standardized process, document it as much as possible, and learn from both your successes and failures.

In the next chapter, we will cover some of the basic concepts any threat hunter should be familiar with, including how operating systems work, networking basics, the Windows...
