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.

Operational tasks for SOC engineers

In this section, we will provide an initial list of tasks that have been identified as engineering tasks. You can use this list as a starting point and then add your own tasks based on what works for your specific requirements. Each component that is added to the SOC architecture will have its own task requirements—for example, if you integrate a cloud access security broker (CASB) solution, you will need to carry out similar tasks within that platform to ensure it is well maintained and sending the appropriate information to Microsoft Sentinel.

Daily tasks

A list of daily tasks for SOC engineers is as follows:

  • Monitor the data connectors for two key performance indicators:

    A. Ensure the data ingestion is consistent with the expected volume; if the volume drops below the average daily rate it could be caused by a configuration error on the source, preventing the data from being sent to Microsoft Sentinel. This should be investigated...
