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.

Upgrading QRadar deployments

IBM QRadar releases major version upgrades once a year and minor upgrades every quarter. The minor upgrades are also called Fix Packs or Upgrade Packs, depending on which version of QRadar you are upgrading. Major version upgrades usually arise with changes to operating system kernels, and QRadar may require a reboot after or during the upgrade. If minor upgrades also contain OS updates, a restart may also be required for minor upgrades. If QRadar Support encounters any defects and they need to be backported to an older version, Intermediate Fixes (IFs) are usually released. These IFs are version-dependent. So before installing any updates, always go through the release notes for that version.

Many times, the estimated load on QRadar in terms of events and flows processed may increase. This happens when more devices are boarded in the customer environment – for example, multiple firewalls installed, many web servers added, and networking devices...
