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.

Getting the incident response team involved

We have already mentioned that there is an open discussion about whether the threat hunting team should be a full-time dedicated team or whether teams involved in Security Operations Center (SOC) or Incident Response (IR) practices should be the ones to dedicate part of their workload to hunting activities. There is not a perfect answer to this, since most of the time the outcome will depend on the size and budget of your organization. But, if your organization has the means to have a full-time dedicated hunting team, or if the team in charge of it is not the same as the one in charge of responding to the incidents, then when should the incident response team get involved?

The answer is pretty obvious: every time you detect activity that is actually malicious. The incident response team is the one in charge of reacting to the breach. The hunting team will help the incident response team by providing as much context as possible to the detected...
