Microsoft Sentinel in Action - Second Edition

By: Richard Diver, Gary Bushey, John Perkins

Overview of this book

Microsoft Sentinel is a security information and event management (SIEM) tool developed by Microsoft that helps you integrate cloud security and artificial intelligence (AI). This book will teach you how to implement Microsoft Sentinel and understand how it can help detect security incidents in your environment with integrated AI, threat analysis, and built-in and community-driven logic. The first part of this book will introduce you to Microsoft Sentinel and Log Analytics, then move on to understanding data collection and management, as well as how to create effective Microsoft Sentinel queries to detect anomalous behaviors and activity patterns. The next part will focus on useful features, such as entity behavior analytics and Microsoft Sentinel playbooks, along with exploring the new bi-directional connector for ServiceNow. In the next part, you’ll be learning how to develop solutions that automate responses needed to handle security incidents and find out more about the latest developments in security, 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 Microsoft Sentinel to fit your needs and protect your environment from cyber threats and other security issues.

Chapter 3: Managing and Collecting Data

One of the primary purposes of a Security Information and Event Management (SIEM) solution is to centralize the storage and analysis of security events across a diverse range of products that provide protection across your organization's IT infrastructure. To do this, the solution needs to connect to those data sources, pull the data into a central store, and manage the life cycle of that data to ensure it is available for analysis and ongoing investigations.

In this chapter, we will review the types of data that are most interesting and useful for security operations, and then explore the functionality available to connect to multiple data sources and ingest that data into Microsoft Sentinel by storing it in the Log Analytics workspace. Once the data is ingested, we need to ensure the appropriate configuration for data retention to maximize the ability to hunt for events and other security information, while also ensuring the cost of...
