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 Rules and Offenses

The greatest challenge for any security team across organizations is to receive informed alerts and then perform incident management. Now, what do we mean by informed alerts? In QRadar, we have discussed how data is collected (Chapter 4). What do we do with this data? We correlate this data against the rules that are defined in QRadar.

Rules are security conditions against which every event is matched. If the event matches the rule, the event is tagged with the rule name. If the rule conditions are matched, then an alert is generated. In QRadar, we call security alerts offenses. For every offense triggered, we correlate events and flows to break down and explain the offense. So, when it comes to offense analysis, the Security Operations Center (SOC) analyst wants to get relevant information about the offense or attack. Once the analyst has the information, the analyst can look up whether it has happened before. If it has happened before, there will be a...
