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.

Different types of QRadar rules

Rules are lists of security conditions that are defined. QRadar has hundreds of rules out of the box. These rules cater to different use cases for cyber-attacks. The use cases are derived from continuous cyber-attacks that happen around the world. The QRadar development team works on different security use cases and continues to add new rules. These rules are added to QRadar via auto updates (we will discuss auto updates later in this chapter). Along with the default rules in QRadar, QRadar users can also create new custom rules based on events, flows, common rules (both events and flows), and other offenses. These are the different types of rules in QRadar:

  • Event rules: Rules are categorized based on what kind of data is required in the rule conditions. When events are evaluated against certain values, those rules are called event rules. These event rules will consist of different conditions for one or more events that happen in real time.
