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.

Services involved in the integration of an event log

In the previous section, we learned how to ingest event logs. The journey of an event log from being pushed to or pulled by QRadar to it being parsed, and then correlated and stored is called the event pipeline. An event pipeline can be imagined as a constant array of upcoming events in QRadar.

The preceding diagram shows how the events from different log sources are integrated into QRadar using different QRadar services.

The different shapes on the left-hand side of Figure 4.1 suggest the different log sources, from where either the events are pushed by the log sources or pulled by QRadar. This depends on whether we use an active protocol or passive protocol. Protocols come under the ecs-ec-ingress service.

As we learned in Chapter 3, license that is required to collect and process the events. This license is the Events per Second...
