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.

Walking through an existing workbook

We are going to take a look at an existing template that has most of the features available to workbooks. This may give you an idea of what you can do with your workbooks, or at least show you how to set up a workbook to do what you want.

The Azure Active Directory (Azure AD) Sign-in logs template has a wide variety of charts and graphs in it. In addition, it shows how to allow users to change parameters, and it shows how you can make columns in a table and display information in a more graphical way.

If you do not have the SigninLogs data type available, which the Azure AD Sign-in logs workbook uses to get its information, it is recommended that the Azure AD connector be enabled for your Azure Sentinel instance. Refer back to Chapter 3, Data Collection and Management, for guidance on how to do this. If you cannot get this connector activated, for whatever reason, you can follow along in the book. However, you will have a better experience...
