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.

Working with Livestream

Livestream is a new feature for Azure Sentinel that will allow you to watch one or more hunting queries in real time, to see new results as they occur. This can be useful when performing an investigation, to watch whether a query has any new results without having to constantly rerun the query.

Note

At the time of writing this book, the Livestream feature was still in preview and, as such, the features and functionality may have changed.

Looking back at Figure 10.8, the last entry in the context menu is called Add to livestream. Selecting this will add the query to the Livestream window, as follows:

Figure 10.9 – Adding a query to Livestream

While this query is added to Livestream, it is not yet running. Click on the Open livestream button on the bottom of the query's detail page. If there is more than one query listed on the page, make sure to select the query you want to watch before clicking this button.
