Tutorial On Creating A New User & Inviting An External User


Role-Based Access Control Assigning A User A Contributor Role In Azure & Removing Role Assignments(RBAC) is a key feature in Microsoft Azure that enables you to manage access to Azure resources. RBAC allows you to grant specific permissions to users, groups, or applications at a certain scope, such as subscription, resource group, or individual resource level. By using RBAC, you can control who has access to what resources in your Azure environment, ensuring security and compliance. Azure RBAC is an authorization system built on Azure Resource Manager(ARM) that provides access management to Azure resources.

In this blog post, we'll delve into the step-by-step process of assigning Azure roles using the Azure Portal. Whether you're a seasoned Azure administrator or just getting started, understanding RBAC and its implementation in Azure Portal can streamline your access management process and bolster your cloud security posture.


To control access to resources using Azure RBAC is to assign Azure roles and this role assignment consists of three elements: security principal, role definition, and scope.

Principal of security
An object that represents a user, group, service principal, or managed identity making a request for access to Azure resources is called a security principal. Any of these security principles can have a job assigned to it.

Role Definition A group of permissions makes up a role definition. Usually, it's just referred to as a role. A role specification describes the possible actions, such as

Azure rolePermissions
OwnerGrants full access to manage all resources Assign roles in Azure RBAC
ContributorGrants full access to manage all resources Can't assign roles in Azure RBAC Can't manage assignments in Azure Blueprints or share image galleries
ReaderView Azure resources

Scope Scope is the set of resources that the access applies to. When you assign a role, you can further limit the actions allowed by defining a scope. In Azure, you can specify a scope at four levels: management group, subscription, resource groups and resources. Scopes are structured in a parent-child relationship. You can assign roles at any of these levels of scope.

Also note that Azure RBAC has several Azure Built-In roles that you can assign to users, groups, service principals, and managed identities. Role assignments are the way you control access to Azure resources, Access is granted by creating a role assignment, and access is revoked by removing a role assignment. If the built-in roles don't meet the specific needs of your organization, you can create your own Azure Custom Roles.


To make a user an administrator of an Azure subscription, can only be done by a Global Administration at the subscription scope. The Owner role gives the user full access to all resources in the subscription, including the permission to grant access to others.
