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.

Exploring log source and flow integration issues

As we know, QRadar ingests data that in the form of events and flows. As such, let’s look at issues related to log source and flow integration in QRadar. We will begin by discussing the autoupdate issues you might face and then move on to log source configuration issues. You will also be provided with resources such as the QRadar DSM guide and the IBM QRadar Community forum for troubleshooting purposes. Finally, we will cover flow integration issues, explaining various configuration parameters related to flows and providing resources to understand and customize flow parameters. Let’s get started!

Autoupdate issues

For the log source integration, we know that QRadar uses different protocols and DSMs. QRadar’s autoupdate feature is responsible for updating these protocols and DSMs, provided it is configured.

Autoupdate is a feature wherein QRadar reaches out to external IBM servers to download the latest updates...
