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.

Getting to know DSM Editor

We have discussed in detail event data and the ingestion of event data in QRadar and now understand that IBM provides DSMs out of the box for QRadar to parse incoming event data. What happens when IBM does not have a DSM for a data source that you want to ingest? What would be the state of the ingested event data? Will it be partially parsed? To answer these queries, IBM has introduced a tool called DSM Editor. DSM Editor is built into Qradar; no special package is required for its installation.

In earlier versions of Qradar, there was a feature called Universal Log Source, where we had to define the parsing logic for incoming data. Parsers had to be written. As it was a manual process, it was not very efficient. But now with the DSM Editor, most of the processing is automatic.
