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 introduced Azure Sentinel and how it fits into the cloud security landscape. We explored some of the widely used acronyms for both problems and solutions and then provided a useful method of mapping these technical controls to the wide array of options available from many security platform providers today. We also looked at the future state of SOC architecture to ensure you can gain visibility and control across your entire infrastructure: physical, virtual, and cloud-hosted.

Finally, we looked at the potential cost of running Azure Sentinel as a core component of your security architecture and how to carry out the scenario-mapping exercise to ensure you are constantly reviewing the detections, the usefulness of the data, and your ability to detect and respond to current threats.

In the next chapter, we will take the first steps toward deploying Azure Sentinel by configuring an Azure Monitor workspace. Azure Monitor is the bedrock of Azure Sentinel...
