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.

Integrating intelligence with Cortex

As was mentioned at the beginning of the chapter, Cortex is a powerful engine to analyze observables and get intelligence from external sources.

The integration of TheHive and Cortex allows you to get threat intelligence information from different sources without having to change to different platforms. As you learned in the previous part, you only need to register an observable and select the analyzers where the information will be searched.

Also, you can integrate Cortex with other threat intelligence platforms such as the Malware Information Sharing Project (MISP). The following diagram shows the way this integration can be done:

It is also possible to initiate cases in an automated way by receiving alerts from different sources such as SIEMs and emails. This feature will be seen in the next chapter.
