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 2: Azure Monitor – 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 Azure Sentinel. This is the first component that needs to be designed and configured when implementing Azure 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 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.

By the end of this chapter you will know how to set up a new workspace, connect to resources to gather data, enable Azure Sentinel for data analysis, and configure some of the advanced features to ensure security and cost management.

We will cover the following...
