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.

Detecting malicious behavior using Sigma rules

One of the challenges for organizations is the standardization and integration of different security tools and the normalization of the formats that these tools use to process and store the information.

Sigma was created under the idea of developing generic rules in a structured format that can be transformed into specific query formats for different Security Information and Event Management (SIEM) systems. With Sigma, you can create rules under specific criteria of detection engineering, regardless of the platform you are using to hunt threats, as you can see in the following figure:

The advantage of this approach is that researchers can create universal rules shared with the community and used by everyone.

The main creators of the Sigma project are Florian Roth (Twitter handle @cyb3rops) and Thomas Patzke (Twitter handle @blubbfiction).
