Incident Response with Threat Intelligence

By: Roberto Martinez

Overview of this book

With constantly evolving cyber threats, developing a cybersecurity incident response capability to identify and contain threats is indispensable for any organization regardless of its size. This book covers theoretical concepts and a variety of real-life scenarios that will help you to apply these concepts within your organization. Starting with the basics of incident response, the book introduces you to professional practices and advanced concepts for integrating threat hunting and threat intelligence procedures in the identification, contention, and eradication stages of the incident response cycle. As you progress through the chapters, you'll cover the different aspects of developing an incident response program. You'll learn the implementation and use of platforms such as TheHive and ELK and tools for evidence collection such as Velociraptor and KAPE before getting to grips with the integration of frameworks such as Cyber Kill Chain and MITRE ATT&CK for analysis and investigation. You'll also explore methodologies and tools for cyber threat hunting with Sigma and YARA rules. By the end of this book, you'll have learned everything you need to respond to cybersecurity incidents using threat intelligence.

Identifying and containing threats

As you learned in Chapter 2, Concepts of Digital Forensics and Incident Response, according to the SANS Incident Response process, phase 2 – identification, and phase 3 – containment, are essential to reduce the impact of a cyberattack, as shown in the following diagram:

Incident response sometimes starts with the escalation of an alert or a user reporting the disruption of a service or the discovery of a data leak. Once a case has been created regarding an incident, the next step is to follow the playbooks associated with the incident.

The more information you have about the incident, the better you can understand the nature of the attack, especially if you use frameworks such as MITRE ATT&CK and you have reliable threat intelligence sources of information.

However, at this point, you just have information about the incident's symptoms,...
