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.

Summary

In this chapter, you learned about Azure Sentinel workbooks and how their interactive display is used to show information to users. Workbooks can be used to help determine whether there is something in your environment that needs investigation.

You learned how to create and edit a new workbook, using the various step types provided. You learned how to define parameters using a new step, as well as coming from a query, and how to use those parameters to further filter your queries.

They can display a combination of text, various graphs, metrics, and links including tabs. Using parameters, the workbooks can be made to change what information is presented, to help determine whether there is an incident that needs to be investigated.

Finally, you learned how to change the advanced settings on a step to change how it operates and how it looks. You learned how to get multiple steps to show up on the same row in a graph, and how one graph can communicate with another through...
