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.

The Insider Threat – Detection and Mitigation

From this chapter onward, we will look in detail at the practical application of what we learned in the last seven chapters. QRadar provides a provision wherein Docker-like applications can be installed, called QRadar apps. These apps vary in nature depending on what type of data they consume and how they use this data to provide value to customers. One such app that we will discuss in detail is User Behavior Analytics, also known as UBA.

When thinking about securing an organization, we usually think of the threat actors that come into play. Mostly, we think of securing our organization from outside threats by using firewalls, intrusion prevention systems, honeypots, and so on. If we look at the current trends in security breaches, we find that some threat actors are part of the same organization where the breach has happened. These actors are called insider threats.

The UBA app helps us monitor user behavior. If there is any...
