Learn Azure Sentinel

By: Richard Diver, Gary Bushey

Overview of this book

Azure Sentinel is a Security Information and Event Management (SIEM) tool developed by Microsoft to integrate cloud security and artificial intelligence (AI). Azure Sentinel not only helps clients identify security issues in their environment, but also uses automation to help resolve these issues. With this book, you’ll implement Azure Sentinel and understand how it can help find security incidents in your environment with integrated artificial intelligence, threat analysis, and built-in and community-driven logic. This book starts with an introduction to Azure Sentinel and Log Analytics. You’ll get to grips with data collection and management, before learning how to create effective Azure Sentinel queries to detect anomalous behaviors and patterns of activity. As you make progress, you’ll understand how to develop solutions that automate the responses required to handle security incidents. Finally, you’ll grasp the latest developments in security, discover techniques to enhance your cloud security architecture, and explore how you can contribute to the security community. By the end of this book, you’ll have learned how to implement Azure Sentinel to fit your needs and be able to protect your environment from cyber threats and other security issues.

Chapter 10: Threat Hunting in Azure Sentinel

Threat hunting is part science, part art, and part intuition. Usually, you are looking for something that may have happened in your environment. It may be that you think something has happened due to external events, such as something odd showing up in the workbooks, a notice from a threat intelligence feed, or even something you just read about on the internet, and you want to investigate. No matter why you are performing your hunt, the tools in Azure Sentinel, including queries and Jupyter Notebooks, remain the same.

Threat hunting is a series of activities that you will perform during your investigation. While there is no set guidance on how to perform threat hunting, this chapter will introduce you to the tools that are available in Azure Sentinel to help you perform your investigations.

A brief introduction on how to perform threat-hunting activities will also be discussed, which will include aspects such as how to determine where...
