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.

The Atomic Red Team testing cycle

In line with the threat hunting cycle, Red Canary has the Atomic Red Team testing cycle. First, you choose the technique (or the permutation of a technique) you want to test for and execute the test. Always start with places where you know you have the strongest visibility. Then, verify whether you have detected the technique. If you didn't, you have to ask yourself whether you are collecting data from the right data sources. In the event that you are, you may need to refine your collection. But if you are not, then you should establish the right collection process and make sure you are gathering the data from the right data sources.

Finally, the process starts all over again:

Important Note

When carrying out this type of test, do it first in your lab environment. Make sure you don't run any tests in a production environment without the right permissions and...
