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.

Summary

This chapter showed you how to create an integration with a solution – in our example, ServiceNow – to provide a single place to process security incidents. It does not matter what alert source the security incident started from or who needs to work on it. There are countless ways to achieve this outcome. We only covered a more common approach in this chapter.

Be creative and focus on simplicity and licensing reduction. For example, if Sentinel does not provide correlation for alerts coming from an alert source because that alert source has very high fidelity, then consider ingesting those alerts directly into ServiceNow and bypassing Sentinel to save on licensing costs and to reduce complexity in your architecture.

We also only scratched the surface of what can be done with a security incident once it is automatically created in ServiceNow Security Incident Response. ServiceNow is not just a workflow and case management solution with fancy forms and dashboards...
