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

This chapter introduced you to Azure Sentinel Analytics queries and the Analytics page. You not only learned about the different rule types but also how to create your own rules using the analytic rules templates that Microsoft has provided to make it easier. In addition, you learned how to create both a scheduled and a Microsoft incident creation rule. Finally, you learned how to manage your existing analytic rules.

You are now ready to start creating the rules needed to monitor your environment. Take a look at the extensive list of rule templates that Microsoft provides and see which of those will be useful. Then, create your own rules to fill in the blanks.

The next chapter will introduce Azure workbooks, which allow you to create very useful tables, charts, and graphs to get a better understanding of your data.
