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.

Working with Microsoft Sentinel hunting queries

While there are a lot of pre-existing queries, with more being added all the time, there may be times when you need to add your own or modify an existing query to better suit your needs.

Adding a new query

To add a new query, click on the New Query button at the top of the Hunting page. This will open the Create custom query page, as shown in the following screenshot. This is very similar to creating a new scheduled query, as discussed in Chapter 7, Creating Analytic Rules, so you can read the Creating a new rule using the wizard section as a refresher:

Figure 11.7 – Adding a new query

Fill in the Name, Description, and Custom query fields. If your query has any entities, use the Entity mapping section to add the entity mapping to the query. Remember to add them one at a time. Finally, select one or more tactics (not shown in the screenshot) that this query is using.
