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, we reviewed the importance of data quality, using the 7 Vs of big data as a guide to selecting the right data. We also looked at the various data connectors available to retrieve logs from a wide variety of sources, and the importance of constantly reviewing the connectors for updates and additional resources, such as workbooks. You now have the skills required to set up data connectors to begin ingesting data for later use in analysis and threat hunting.

Ongoing data management plays a key part of this solution, ensuring you maintain cost efficiency of the solution without losing valuable information that can help identify risk and mitigate potential loss. Use the information in this chapter to apply to your own environment, and review regularly.

In the next chapter, you will learn how to integrate threat intelligence feeds into Azure Sentinel, in order to enrich your data with insights from security experts and make your investigations more effective...
