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.

Exploring protocols and DSMs

There are two factors we need to consider when integrating event data in QRadar:

  • How to transfer data from end devices to QRadar
  • How to parse or make sense of data that is received

Let’s look at each of these considerations in detail.

How to transfer data from applications to QRadar

Different applications can be installed and run on different platforms or operating systems. For example, while some applications could be on a Windows machine on a bare-metal server, other applications could be running on the AWS cloud or some security appliance, such as a Ciscofirewall deployed in your organization.

All these endpoints are known as log sources, as we receive log data from them. As the log sources are on different platforms, they might also use different technologies and ways to log the data. For example, the AWS log sources can use something such as a S3 bucket, while a Linux security log would be saved on the same Linux...
