![]() Role assignments are transitive for groups which means that if a user is a member of a group and that group is a member of another group that has a role assignment, the user will have the permissions in the role assignment. You can assign roles using the Azure portal, Azure CLI, Azure PowerShell, Azure SDKs, or REST APIs.įor more information, see Steps to assign an Azure role. Marketing users do not have access to resources outside the pharma-sales resource group, unless they are part of another role assignment. This means that users in the Marketing group can create or manage any Azure resource in the pharma-sales resource group. In this example, the Marketing group has been assigned the Contributor role for the pharma-sales resource group. ![]() The following diagram shows an example of a role assignment. Access is granted by creating a role assignment, and access is revoked by removing a role assignment. Role assignmentsĪ role assignment is the process of attaching a role definition to a user, group, service principal, or managed identity at a particular scope for the purpose of granting access. You can assign roles at any of these levels of scope.įor more information about scope, see Understand scope. Scopes are structured in a parent-child relationship. In Azure, you can specify a scope at four levels: management group, subscription, resource group, or resource. This is helpful if you want to make someone a Website Contributor, but only for one resource group. When you assign a role, you can further limit the actions allowed by defining a scope. Scope is the set of resources that the access applies to. For example, if a user has read data access to a storage account, then they can read the blobs or messages within that storage account.įor more information, see Understand Azure role definitions. This video provides a quick overview of built-in roles and custom roles.Īzure has data actions that enable you to grant access to data within an object. If the built-in roles don't meet the specific needs of your organization, you can create your own Azure custom roles. For example, the Virtual Machine Contributor role allows a user to create and manage virtual machines. Roles can be high-level, like owner, or specific, like virtual machine reader.Īzure includes several built-in roles that you can use. A role definition lists the actions that can be performed, such as read, write, and delete. You can assign a role to any of these security principals.Ī role definition is a collection of permissions. Security principalĪ security principal is an object that represents a user, group, service principal, or managed identity that is requesting access to Azure resources. A role assignment consists of three elements: security principal, role definition, and scope. This is a key concept to understand – it's how permissions are enforced. The way you control access to resources using Azure RBAC is to assign Azure roles. Allow an application to access all resources in a resource group.Allow a user to manage all resources in a resource group, such as virtual machines, websites, and subnets.Allow a DBA group to manage SQL databases in a subscription.Allow one user to manage virtual machines in a subscription and another user to manage virtual networks. ![]() Here are some examples of what you can do with Azure RBAC:
