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.

QRadar Use Case Manager app

While working with QRadar, you might have noticed the enormity of data and the number of rules that a QRadar administrator must work with. The sheer number of rules that come out of the box with the system, and the rules added when new apps and extensions are installed, can be overwhelming. On top of that, some organizations need customized alerts for which custom rules must be created. Managing these rules is a challenge. As we learned in earlier chapters, enabling all the rules is counterproductive and will adversely affect QRadar performance. So how do you manage QRadar rules? The QRadar Use Case Manager app is designed to manage QRadar rules and optimize them. We will look at both these functionalities.

Before we discuss this app in detail, let us understand what the MITRE ATT&CK framework is and how it is used by the QRadar Use Case Manager app.

MITRE ATT&CK is a framework designed for security analysts, threat hunters, red/blue teams...
