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.

How do searches work?

Though we have briefly discussed the idea of searching, let us dig deep into it and understand the mechanism of QRadar search.

Figure 6.1 – Components involved in a QRadar search

Figure 6.1 – Components involved in a QRadar search

In the preceding figure, we have tried to cover all the QRadar components that are involved in a QRadar search. We can see a security analyst on the left-hand side trying to run a search on the QRadar Console Graphical User Interface (GUI). We can also see three Event Processors and one Flow Processor where data is stored. Then there are Data Node 1 and Data Node 2, which are attached to Event Processor 2. There are two Event Collectors, which are collecting logs, and those logs are stored on Event Processor 1. Similarly, flows are collected by QRadar Network Insights (QNI) and another Flow Collector (QFlow service) and are sent to the Flow Processor.

In the figure, we can see legends that are defined. The blue colored line depicts the search query...
