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.

Installing QRadar

The first step of QRadar installation is to understand which QRadar components will be needed in the deployment. We can always add processors and collectors when needed. However, we must start with the first step, which is requirement gathering. Let’s get started:

  1. Understand the amount of data in terms of EPS and FPM that will be ingested in QRadar. This will help us understand the number of processors required.
  2. Check whether the data has to be collected from geographically different regions, and also check the data privacy rules of the countries/states. This helps us to understand whether we will need processors or collectors. If the bandwidth is pretty low for the remote sites, we may also need Disconnected Log Collector (DLC).
  3. As per the EPS and FPM, ensure that hardware and software requirements are met. Ensure that the machine has enough memory, CPU, and storage before starting the installation.
  4. Understand the data retention policy...
