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.

Overview of the Azure Sentinel connector

While there are many logic app connectors, and more are being added all the time, the one we are concerned with is the Azure Sentinel connector. It provides us with the trigger that can kick off our playbook. It also contains various actions that can perform tasks such as obtaining information about a specific incident, getting information about the entities associated with an alert, updating an incident, and more.

Note

It should be noted that at the time this chapter was written, all the features of the Azure Sentinel connector were in preview, so they could have changed from what is shown and discussed here.

The connector currently has one trigger called When a response to an Azure Sentinel alert is triggered. This means that the trigger will fire whenever an alert is triggered. It is worth noting that while the trigger returns a lot of information, it does not return the actual incident that gets created, if one gets created at all...
