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 6: Microsoft Sentinel Logs and Writing Queries

In the previous chapter, we looked at the Kusto Query Language (KQL) and gave a brief introduction to how to use it. In this chapter, we will learn about the Microsoft Sentinel Logs page. The Microsoft Sentinel Logs page is where you can see the various logs in your workspace, determine the type of data that makes up the logs, create the queries that will be used in the Analytics rules and threat hunting, as well as save these queries for later use. This will help you in creating rules and is an integral part of investigating incidents.

As part of this chapter, we will provide an overview of the Microsoft Sentinel Logs page, learn about the various sections, and look at how to use KQL to write queries. We will review the Logs screen in Microsoft Sentinel and show how to look at columns that make up the table, using both the UI and KQL. We will also look at the steps you can take to help develop your queries.
