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.

Chapter 11: Creating Playbooks and Logic Apps

In the previous chapters, you learned about the Security Information and Event Management (SIEM) side of Azure Sentinel. Now it is time to learn about the Security Orchestration, Automation, and Response (SOAR) capabilities.

Azure Sentinel's SOAR features allow for automated, or semi-automated, responses to the creation of alerts. This allows you to develop workflows that can perform tasks such as blocking an IP address from getting through a firewall, blocking a suspicious username, or something simple such as sending an email to the security team letting them know a new high-severity alert was generated. When you combine the automation capabilities offered by Azure Sentinel with the protection capabilities of the many other security products you deploy, the sky's the limit!

In this chapter, you will learn about Azure Sentinel playbooks, including how to write and edit them, configuring their workflow, and managing them...
