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.

Implementing TI connectors

Azure Sentinel provides a data connector specifically for integration with TIP solutions (both commercial and open source). This section will provide walk-through guidance for the steps required to ingest TI data into Azure Sentinel, using MineMeld as an example:

  1. Enabling the data connector for TIPs
  2. Registering app permission in Azure AD
  3. Configuring the TI feed (MineMeld)
  4. Confirming that the TI feed data is visible

    Note

    At the time of writing, this feature is still in public preview. You can enable this solution in your Azure Sentinel workspace to gain access to these features; however, you should expect it to change as it is developed.

Let's discuss each of these steps in detail in the following sections.

Enabling the data connector

Use the following steps to enable the data connector for TIPs within Azure Sentinel:

  1. Navigate to the Azure Sentinel portal and go to the Data connectors page, as shown in the following...
