By: Richard Diver, Gary Bushey, John Perkins

Overview of this book

Microsoft Sentinel is a security information and event management (SIEM) tool developed by Microsoft that helps you integrate cloud security and artificial intelligence (AI). This book will teach you how to implement Microsoft Sentinel and understand how it can help detect security incidents in your environment with integrated AI, threat analysis, and built-in and community-driven logic. The first part of this book will introduce you to Microsoft Sentinel and Log Analytics, then move on to understanding data collection and management, as well as how to create effective Microsoft Sentinel queries to detect anomalous behaviors and activity patterns. The next part will focus on useful features, such as entity behavior analytics and Microsoft Sentinel playbooks, along with exploring the new bi-directional connector for ServiceNow. In the next part, you’ll be learning how to develop solutions that automate responses needed to handle security incidents and find out more about the latest developments in security, 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 Microsoft Sentinel to fit your needs and protect your environment from cyber threats and other security issues.

Managing permissions for the workspace

Before we connect and store data in the workspace and enable Microsoft Sentinel to carry out analytics on the data, let's review the options to secure access to this new resource. Azure provides three main levels of access to resources:

  • Owner: Has the highest level of access to resources
  • Contributor: Can create and modify resources, but cannot grant or revoke access
  • Reader: Can view all resources

These permissions can be granted at four different levels:

  • Subscription: The highest level of access, applies to all resources within the subscription
  • Resource group: Applies to a specific resource group, which may contain multiple workspaces
  • Workspace: Applies only to a specific workspace
  • Table-level RBAC: Applies to individual tables within the Log Analytics workspace

    While there is no user interface available to set permissions on individual tables within the log, you can create Azure custom...
