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.

Choosing the right intel feeds for your needs

With Azure Sentinel, you can import TI from multiple sources to enhance the security analyst's ability to detect and prioritize known threats and IOCs. When configured, several optional features become available within the following Azure Sentinel tools:

  • Analytics: This includes a set of scheduled rule templates you can enable to generate alerts and incidents based on matches of log events.
  • Workbooks: This provides summarized information about the TI imported into Azure Sentinel and any alerts generated from analytics rules that match your threat indicators.
  • Hunting: Hunting queries allow security investigators to use threat indicators within the context of common hunting scenarios.
  • Notebooks: Notebooks can use threat indicators to assist with the investigation of anomalies and to hunt for malicious behaviors.

There are several options available to gain access to TI feeds, and you may choose to generate your...
