Building a Next-Gen SOC with IBM QRadar

By: Ashish M Kothekar

Overview of this book

This comprehensive guide to QRadar will help you build an efficient security operations center (SOC) for threat hunting and need-to-know software updates, as well as understand compliance and reporting and how IBM QRadar stores network data in real time. The book begins with a quick introduction to QRadar components and architecture, teaching you the different ways of deploying QRadar. You’ll grasp the importance of being aware of the major and minor upgrades in software and learn how to scale, upgrade, and maintain QRadar. Once you gain a detailed understanding of QRadar and how its environment is built, the chapters will take you through the features and how they can be tailored to meet specifi c business requirements. You’ll also explore events, flows, and searches with the help of examples. As you advance, you’ll familiarize yourself with predefined QRadar applications and extensions that successfully mine data and find out how to integrate AI in threat management with confidence. Toward the end of this book, you’ll create different types of apps in QRadar, troubleshoot and maintain them, and recognize the current security challenges and address them through QRadar XDR. By the end of this book, you’ll be able to apply IBM QRadar SOC’s prescriptive practices and leverage its capabilities to build a very efficient SOC in your enterprise.

Part 3: Understanding QRadar Apps, Extensions, and Their Deployment


In this chapter, we have discussed how the UBA app can be installed and configured correctly. Always remember that UBA is a heavy application in terms of computational resources and so we should install App Host first. Additionally, the UBA app is updated regularly with new features, new rules are added, and new searches are introduced. To aid with this, always keep your UBA app up to date.

Also, you should use QRadar NTA along with UBA as it helps get granular information if there is anomalous behavior identified. The risk scores provide guidance on what behavior to look at first. The dashboards for both applications will help you detect as well as mitigate insider threats.

In the next chapter, we will dig deep into how QRadar leverages Watson, IBM’s cognitive engine, to integrate its AI capabilities with the sea of data that QRadar possesses.
