Microsoft Sentinel in Action - Second Edition

By: Richard Diver, Gary Bushey, John Perkins

Overview of this book

Microsoft Sentinel is a security information and event management (SIEM) tool developed by Microsoft that helps you integrate cloud security and artificial intelligence (AI). This book will teach you how to implement Microsoft Sentinel and understand how it can help detect security incidents in your environment with integrated AI, threat analysis, and built-in and community-driven logic. The first part of this book will introduce you to Microsoft Sentinel and Log Analytics, then move on to understanding data collection and management, as well as how to create effective Microsoft Sentinel queries to detect anomalous behaviors and activity patterns. The next part will focus on useful features, such as entity behavior analytics and Microsoft Sentinel playbooks, along with exploring the new bi-directional connector for ServiceNow. In the next part, you’ll be learning how to develop solutions that automate responses needed to handle security incidents and find out more about the latest developments in security, 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 Microsoft Sentinel to fit your needs and protect your environment from cyber threats and other security issues.

Summary

Now, you have learned about how to start doing threat hunting in Microsoft Sentinel. You learned about the Hunting page, the Notebooks page with its Jupyter notebooks, and got a brief introduction on how to perform a threat-hunting investigation.

We looked at the tools that Microsoft Sentinel provides to assist with threat hunting. This includes queries that only get run periodically, either due to factors such as needing to look for a specific piece of information or the fact that they would return too many results to be useful on a scheduled basis.

Another tool that can be used is the hosted instances of Jupyter notebooks. These notebooks allow you to combine text and code into one location to make hunting easier and repeatable. In addition, notebooks can query not only Microsoft Sentinel logs but also third-party information using programming languages, including PowerShell and Python.

In the next chapter, we will look at using Microsoft Sentinel playbooks to help...
