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.

Escalating incidents from detection

An important feature when we are talking about SOAR is the capacity to escalate or automate processes between systems.

We can do this in several ways. We can either automate alerts to receive notifications under certain conditions and take some specific actions according to an IR playbook or we can trigger a new case from a SOC alert.

Emulating suspicious behavior

To emulate suspicious behavior, we are going to create a new Windows user to trigger an alert, and then we will escalate this alert to open an incident case.

First, let's generate a security event related to the creation of a local Windows user from the command line:

  1. To create the new user, write the following command on the Windows Terminal/PowerShell console:
    New-LocalUSer -Name "PamB" -NoPassword

The new user is now created and enabled, as you can see in the following screenshot:
