Azure RBAC

 

Azure Role-Based Access Control (RBAC) is a system used to manage user access to Azure resources. With RBAC, you can grant specific permissions to users, groups, or applications at a certain scope, such as subscription, resource group, or individual resource level. This helps in ensuring that users have the necessary permissions to perform their tasks, while also maintaining security by restricting access to sensitive resources.

RBAC in Azure operates based on the following key components:

1. **Role Definitions**: These define a set of permissions that can be assigned to users, groups, or applications. Azure provides built-in roles such as Owner, Contributor, and Reader, as well as custom roles that you can define to meet specific requirements.

2. **Role Assignments**: These associate a role definition with a user, group, or application at a specific scope. Role assignments can be made at the subscription, resource group, or resource level.

3. **Scope**: RBAC operates at different scopes within Azure, including management group, subscription, resource group, and resource levels. Permissions granted at a higher scope are inherited by lower scopes unless explicitly overridden.

4. **Azure AD Users, Groups, and Service Principals**: RBAC uses Azure Active Directory (Azure AD) to manage identities. Users, groups, and service principals (representing applications) can be assigned roles to control access to Azure resources.

RBAC provides a flexible and scalable way to manage access control in Azure, allowing organizations to enforce the principle of least privilege by granting only the permissions necessary for users to perform their tasks. It's an essential component of Azure's security and governance framework.
