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.

Understanding the data that's been collected

Threat hunting involves dealing with event logs from different data sources. There is not a right answer for what is the correct amount of data or the right data sources, since it will depend on what you are looking for and the resources of your organization. But, in any case, the data that's used for threat hunting doesn't exist in a vacuum and it will be determined by the operating systems in the organization's endpoints, the devices connected to the organization's network, and even by the security solutions that have been implemented.

In the previous chapters, we stated that part of the threat hunter's skill set was being able to understand the network architecture and recognize unusual patterns both in the network activity and in the data that's collected from endpoints and applications. So, before we look at the data sources themselves, let's quickly review some of the basics regarding operating...
