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.

Integrating Logs and Flows in QRadar

When an application is developed, a provision to log the details in it is also developed alongside. Logging is usually used to debug the application while developing as well as to troubleshoot and provide support to it. Every application can have different types of logs. Some of these logs contain security information, such as identity and access management logs, buffer overflow messages, and file tampering. All such logs play an important role in understanding the security risk for an organization.

Consider a scenario where a hacker gains access to a system; the first thing the hacker does is delete or purge the entries in the logs that would alert their unauthorized access to the system. This way, the hacker remains safe and can then do lateral movement to access other critical servers. So, how do we monitor and detect such attacks? The answer is by using flows in conjunction with logs. As the adage goes, flows don’t lie!
