For cloud resource management to be effective, access management is essential for any organization. An IT employee will require a higher permission level than a business user because they are responsible for cloud deployment design, development, management, and support.
Azure offers flexible role-based access control to its resources. This allows you to efficiently manage permissions for different roles. This system is called Azure RBAC.
What is RBAC? What are the benefits of role-based access control in Microsoft Azure
Role-based access control Azure is a role-based authorization on Azure Resource Manager that allows for granular access management to Azure resources. Azure RBAC allows you to effectively segregate the duties of your team and give access that is sufficient to complete their jobs.
Role-based access control Azureallows for:
You can manage different accesses to Azure resources.
Find out what other roles you can fill with these resources.
Find out which areas the different roles have access to.
Some Fundamental Azure Roles
Azure RBAC has approximately seventy roles in-built and four essential roles. Below are the essential roles.
Azure role
Permissions granted
Administrator for User Access
Manages user access to Azure resources
Reader
Only read/view Azure resources
Contributor
You are allowed to create and manage all types of Azure resources as well as new tenants in Azure Active Directory. It cannot grant access to other users.
Owner
Access to all Azure resources, and the ability to delegate access to other users
RBAC (Role Based Access Control Azure), determines whether a user has access.
Azure RBAC uses these steps to determine if you have control of access to a resource.
A token for Azure Resource Manager is given to a service principal. This token contains both the transitive and group memberships.
The attached token is used by the service principal to make a REST API request to Azure Resource Manager.
Azure Resource Manager retrieves and denies all role assignments for the resource that is being performed.
Access to the site will be blocked if the deny assignment rule is in effect. Otherwise, the evaluation will continue.
The Azure Resource Manager reduces the number of role assignments that only apply this user or their groups and specifies the roles of this user for this resource.
Azure Resource Manager now determines whether the API action call is within the user’s role for this particular resource.
If the user does not have the required role in the requested scope, access is denied. Data actions are subject to the same deduction.
DataActions – NotDataActions = Effective Data Permissions
Effective management permissions: Actions – notActions
Access to the requested scope is denied if the user does not have the required role. Otherwise, all conditions are evaluated.
If the role assignment contains conditions, they are considered. Access is granted to anyone else.
Access is granted if all conditions are met. Access is denied to anyone else.
Azure RBAC vs. Azure ABAC: What’s the Difference?
Both Role-based access management Azure (RBAC), and attribute-based access controls (ABAC), are methods of controlling authorizing users and authentication processes. ABAC is however more complicated and requires more time and resources.
How Role Based Access Control Works (RBAC): Some Key Concepts
Azure resources can be controlled by RBAC through the assignment of Azure roles. Each role assignment has three components: role definition and security principal.
Role Definition
A role definition (or a job title) is a collection permissions. It lists all allowed actions such as view, write, or delete.
Azure has many roles that you can use. They can be high-ranking, such as an owner, or precise, like a virtual machine reader.
Security Principle
Security principals are objects that represent users, managed identities, services, or groups who request access to Azure resources. Security principals can be assigned roles.
Scope
The scope is the area to which access is granted. You can limit the actions of roles by creating a scope. Azure allows you to define scope at four levels:
Subscription,
Management Group
Resource, or
Resource Group.
