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.

Creating a simple Microsoft Sentinel playbook

This example will take you through the process of creating a new Microsoft Sentinel playbook. The scenario we are solving is notifying our security analysts, using Microsoft Teams that a new, high-severity incident has been created.

The first step is to create a new playbook that Microsoft Sentinel can use. Remember that for Microsoft Sentinel to be able to use a playbook, it must use the Microsoft Sentinel connector:

  1. Go to the Microsoft Sentinel playbook screen and click the Add Playbook button in the header. Follow the Creating a new playbook section to add a new playbook. I am calling this playbook BookDemo. Select the appropriate resource group and location. For this example, you do not need to store information in Log Analytics.
  2. Once your playbook has been created, click on the Blank Logic App button to create a new logic app that has nothing in it.
  3. On the Logic Apps Designer page, find and select the Microsoft Sentinel...
