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.

Introduction to Microsoft Sentinel playbooks

Microsoft Sentinel uses Azure Logic Apps for its workflow automation. An Microsoft Sentinel playbook is a logic app that uses the Microsoft Sentinel connector to trigger the workflow. As we go through this chapter, many of the screenshots we will be looking at will be logic app pages, which reinforces this concept. The full extent of how to use Logic Apps is beyond the scope of this book, so we will just cover the Microsoft Sentinel connector, which contains logic app triggers and actions for Microsoft Sentinel.

Note

For this chapter, the terms playbook and logic app will be used interchangeably. For more information on Azure Logic Apps, go to https://azure.microsoft.com/en-us/services/logic-apps/.

Logic apps use connectors (not to be confused with Microsoft Sentinel data connectors) and actions to perform a workflow's activities. A logic app connector provides access to events and data. Actions will perform a specific task...
