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.

Adding a new automation rule

As we mentioned previously, to create a new automation rule, click on the +Create button in the header and select Add new rule.

This will open the Create new automation rule pane, as shown in the following screenshot:

Figure 12.5 – Create new automation rule

Enter the rule's name in the Automation rule name text box. You will want to make this rule's name descriptive enough so that someone will understand what it will do by reading the title. For example, Get IP Address information tells the user that the rule will get some IP address information, while Testing 123 doesn't tell the user anything, not that anyone would name their rule that.

Under the name, note that Trigger is automatically set to When incident is created. Refer to the Types of playbooks section in this chapter for more information on this.

The Conditions section is where you set what analytic rules will trigger this automation rule...
