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 9: Incident Management

In Chapter 7, Creating Analytic Rules, you learned that rules in analytics create incidents. These incidents can represent potential issues with your environment and need to be looked at to determine whether they are indeed an issue. Are they false positives, irrelevant to your environment, or actual issues? The way to determine this is through incident management.

There are no hard-and-fast rules for incident management, other than to look at the incidents and determine whether they are actual issues. There are various ways to do this, and this chapter will look at the options Microsoft Sentinel provides to perform these investigations, including a graphical representation of the incident, viewing the full details of the incident, and running other queries to obtain more information.

In this chapter, we will cover the following topics:

  • Using the Microsoft Sentinel Incidents page
  • Exploring the full details page
  • Investigating an incident...
