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.

Digital evidence and forensics artifacts

The main element of any investigation is digital evidence. Digital evidence is information that could be stored or transmitted to other devices. One of the most critical challenges facing a professional investigator is identifying and finding the right evidence that could be relevant to a case.

Edmon Locard, a pioneer in digital forensics, formulated a forensic science principle as this: Every contact leaves a trace, which means that in any contact between two items, there will be an exchange. For example, at a robbery crime scene, a supposed offender could leave their fingerprints on several objects, their shoeprints on the floor, or even some hair; this could be enough to identify and find the suspect.

When it comes to digital devices, we can apply the same principle. We use digital devices every day, such as smartphones, wearables, smart homes, and IoT appliances, and any digital device leaves traces behind. For example, when you connect...
