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.

Creating a playbook to trigger a ticket in ServiceNow

We have already covered what an Azure Sentinel playbook is, and how to create one, in Chapter 11, Creating Playbooks and Logic Apps. As a quick refresher, a playbook is a set of logical steps that are taken to perform an action. These are also referred to as workflows in other applications. Playbooks use Azure Logic Apps technology; the only difference is that a playbook must use the Azure Sentinel connector's trigger. After that, you are able to use any of the many actions that are provided by Azure Logic Apps.

We are going to take this one step further in this section and explain how to use a playbook to create a ServiceNow Security Incident Response (SIR) incident. If you do not already have the SIR module loaded in your ServiceNow environment, follow the instructions located at https://docs.servicenow.com/csh?topicname=t_ActivateSecurityIncidentResponse.html&version=kingstonsecurity.
