Learn Azure Sentinel

By: Richard Diver, Gary Bushey

Overview of this book

Azure Sentinel is a Security Information and Event Management (SIEM) tool developed by Microsoft to integrate cloud security and artificial intelligence (AI). Azure Sentinel not only helps clients identify security issues in their environment, but also uses automation to help resolve these issues. With this book, you’ll implement Azure Sentinel and understand how it can help find security incidents in your environment with integrated artificial intelligence, threat analysis, and built-in and community-driven logic. This book starts with an introduction to Azure Sentinel and Log Analytics. You’ll get to grips with data collection and management, before learning how to create effective Azure Sentinel queries to detect anomalous behaviors and patterns of activity. As you make progress, you’ll understand how to develop solutions that automate the responses required to handle security incidents. Finally, you’ll grasp the latest developments in security, discover 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 Azure Sentinel to fit your needs and be able to protect your environment from cyber threats and other security issues.

Configuring Azure Sentinel connectors

The Azure Sentinel - Data connectors page shows the total number of connectors, how many are currently connected, and how many are in development. An example of the Data connectors page is shown in the following screenshot:

Figure 3.4 – Azure Sentinel Data connectors page

As you can see in the preceding screenshot, there are currently 32 connectors available to implement in this Azure Sentinel workspace. The list is likely to grow over time as more solutions become natively integrated, which is why you can see the ability to filter the list and search for specific data connectors. By selecting the connector on the left-hand side, we can view the connector details on the right-hand side. For this example, we will use the data connector for AWS, as shown in the following screenshot:
