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.

QRadar Risk Manager

QRadar Risk Manager (QRM) is another managed host that can be added to QRadar deployment. For each deployment, there can only be one QRM. QRM uses network topology information such as configuration backup from network devices, and vulnerability data from events to understand and prioritize the risks.

Figure 2.10 – Deployment with QRM

In Figure 2.10, we see that QRM is connected to network devices such as firewalls, intrusion prevention systems, and routers. QRM has multiple features that can make the life of QRadar admin easier. It provides a “discovery” feature. The admin will need to provide the IP address range. QRM will then start as a scan and will discover all the network devices in the subnet. Multiple IP address ranges can be provided, which would make the discovery of different network appliances possible.

Important note

QRM works on layer 3 of the Open Systems Interconnection (OSI) model.
