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.

Workbook step types

Each workbook is comprised of one or more steps. As stated earlier, a workbook is made up of small sections called steps. Each step has a unique name, which can be pretty much anything, and this name can be referenced in other steps. Each step can run on its own, although some may require parameters, either from a parameter step or from other steps.

There are five different types of steps: text, query, metric, parameters, and links/tabs. Each type of step will be discussed in more detail in the following sections. There will also be a section to discuss the Advanced Settings button, as the various step types have the same advanced settings.

To add a new step when editing a workbook, at the bottom of the screen is a list of links matching those shown in the following screenshot. Click on the appropriate link for the type of step you wish to add:
