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.

Playbook pricing

As mentioned in Chapter 1, Getting Started with Microsoft Sentinel, running an Microsoft Sentinel playbook is not included in the ingestion costs of Microsoft Sentinel or Log Analytics. It has separate charges that, though they may be considered small, can add up quickly.

For example, in the East US region, each logic app action that is run (and this includes things such as looking up information, extracting JSON, and sending emails) will cost $0.000025 each time it is used. There is also an additional $0.000125 charge for each standard connector. Granted, this seems small, but if you write a logic app that has 100 actions with 1 connector that gets run every second of every day for a month, that one logic app would cost $3,564 each month!

Now, this is an extreme example, but it serves to remind you that when designing playbooks, you...
