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.

Chapter 12: ServiceNow Integration

As you have read so far, Azure Sentinel is a powerful solution for gathering logs and threat intelligence, and for discovering threats across your entire environment. However, this is only part of the solution required to run a Security Operations Center (SOC). When a security alert is raised in Azure Sentinel, the SOC may need assistance from several other teams in order to investigate the issue, mitigate the threat, and remediate any impact caused.

In order to coordinate these activities, organizations utilize a service management platform, such as ServiceNow, to create cases and track the progress being made by each team. While this chapter is focused on the specifics of using the ServiceNow platform, the procedures may be modified for use on a different platform if it supports integration with Azure Sentinel and Azure Logic Apps.

The process of case management begins by generating alerts within Azure Sentinel; then, those alerts are used...
