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.

Introduction to Azure Sentinel playbooks

Azure Sentinel uses Azure Logic Apps for its workflow automation. In fact, an Azure Sentinel playbook is a logic app that uses the Azure Sentinel connector to trigger the workflow. As we go through this chapter, many of the screens we will be looking at are 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 Azure Sentinel connector, which contains a logic app trigger and actions.

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 Azure 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, such as sending an email, posting a message...
