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.

Data accumulation

Data accumulation is one of the important concepts to understand. Many of the applications, such as dashboards and reports, work on data accumulation. So, what is data accumulation in QRadar?

In Chapter 1, we spoke about the hostcontext service and we saw that there are multiple subservices of hostcontext. One of them is the accumulator service. If configured, the accumulator service is responsible for keeping a separate copy of the data. The data from the Ariel database is not removed or edited in any way. It is just that a separate copy of the small set of data from the Ariel database is maintained. This separate copy of data is called Global View (GV) in QRadar.

For example, we have configured to accumulate Cisco firewall logs where the event name is Connection Denied. The accumulator service will pick up all the events named Connection Denied and store them in a GV. GVs are storage compartments where specific events can be saved or duplicated for easier...
