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.

An investigation is used to determine whether the incident is an issue. For example, an incident describing failed logins could be as simple as someone forgetting their password, or it could be someone trying to crack a password. You will not know which until an investigation is performed.

Now that you know how to look at an incident and retrieve all the information relating to it, it is time to see how to investigate an incident. The main way this is done in Microsoft Sentinel is via the graphical investigation page. This is a graphical interface that not only shows you the incident in question but can also be used to find related information.

When you are looking at an incident's details, at the bottom of...
