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.

Chapter 2: Azure Monitor – Introduction to Log Analytics

In this chapter, we will explore the Azure Monitor Log Analytics platform, which is used to store all the log data that will be analyzed by Microsoft Sentinel. This is the first component that needs to be designed and configured when implementing Microsoft Sentinel and will require some ongoing maintenance to configure the data storage options and control the costs associated with the solution.

This chapter will also explain how to create a new Log Analytics Workspace using the Azure portal, PowerShell, and the CLI. Once a workspace has been created, we will learn how to attach various resources to it so that information can be gathered, and we will explore the other navigation menu options.

We will cover the following topics in this chapter:

  • Introduction to Azure Monitor Log Analytics
  • Creating a workspace using the portal
  • Creating a workspace using PowerShell or the CLI
  • Managing permissions for...
