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.

Creating an analytic rule

As mentioned before, there are two ways to create rules. You can either use a rule template to create a rule or you can create a new one from scratch using the built-in wizards. Let's first try and do this using a rule template.

Creating a rule from a rule template

To use a rule template to create a rule, all you need to do is to select the rule in the list of rule templates. If you can't create the rule, and if you have not already used this rule template to create a rule, then, at the bottom of the rule details pane on the right side of the screen will be a Create rule button. Click it to create the rule.

Note

As stated previously, if this button is grayed out, then there will be some highlighted text above it explaining why. Referring to Figure 7.8, you will notice that we are able to create a rule from the selected template since we meet all the criteria.

When you click on Create rule, you will be taken to the Rule creation wizard...
