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 Incident Forensics (QRIF)

The QRadar Incident Forensics processor is added to the QRadar Console like any other managed host. Packet capture appliances are attached to the QRIF processor. This helps the processor import the required packet capture information from packet capture (PCAP) appliances.

Usually, when we are investigating an offense, we would like to see what happened, which in essence is incident forensics. For example, an offense is triggered for an employee called Bob. If we right-click on Bob and click on Forensic recovery, the QRIF processor will collect all information related to Bob, such as the emails that Bob sent, his downloads, chat sessions, browser history, and so on.

The QRIF processor queries the data based on the filter from the PCAP appliances and recreates the traffic as it is. So, the email attachments that Bob sent are also reconstructed.
