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.

A SOAR use case – identifying malicious communications

Suppose that a monitoring system detects abnormal network behavior and tags the IP address or domain as suspicious and sends it to another system for verification in a database of malicious indicators of compromise (IoCs). 

If this indicator is confirmed to be malicious, the Security Operation Center (SOC) operator opens a new case for a cybersecurity incident and notifies the IR team. The incident responder can then open a new case using the playbook related to this incident and start assigning tasks to the IR team.

If the IR system has integration with a threat intelligence system, you can search for additional information containing the details of a potential campaign, threat actors, affected industries, and related IoCs, as shown in the following figure:
