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.

Leaving No Data Behind

In the previous chapter, we learned how event data is collected and consumed by QRadar. We learned that protocols are needed to collect data while Device Support Modules (DSMs) are required to parse data. Consider a scenario where we want to ingest event data into QRadar but there is no supported DSM. The first thing is to know what the supported DSMs are.

Every month, IBM releases a new DSM guide, a document on how to integrate log sources with QRadar. If your log source is not a part of this DSM guide, then the event data ingested is either categorized as Stored or Unknown. The event data is not parsed. That does not help us with correlation when it comes to matching events with rules. So, whatever event data we are ingesting in QRadar should be parsed properly.

Using a tool called DSM Editor, we can create custom parsers for any type of data that is ingested in QRadar. In this chapter, we will discuss the steps to create custom parsers in QRadar in detail...
