Using Role-Based Access Control (RBAC)
Azure Stack Hub incorporates Role-Based Access Control (RBAC) to define the permissions that users or groups have within the environment. RBAC provides fine-grained access management for resources in Azure Stack Hub and allows administrators to control who can perform actions across the resource stack.
Predefined Roles
Azure Stack Hub offers a set of predefined roles that align closely with Azure roles, such as:
- Owner
- Contributor
- Reader
- User Access Administrator
These roles can be assigned to users and groups at different scopes, such as:
- Management Group
- Subscription
- Resource Group
- Resource
Assigning Roles in the Azure Stack Hub Administrator Portal
To assign a role to a user or group in the Azure Stack Hub Administrator Portal, complete the following steps:
- Navigate to the Azure Stack Hub Administrator Portal.
- Select the scope you wish to assign the role to (e.g., subscription, resource group, or specific resource).
- Click on Access control (IAM) on the left-hand menu to open the identity and access management page.
- Click on the “+ Add” button, then choose “Add role assignment”.
- Select the role you want to assign from the list of available roles.
- Search and select the user or group to whom you want to assign the role.
- Click “Save” to apply the role assignment.
Assigning Roles Using Azure PowerShell
For a more automated approach, you can use Azure PowerShell to assign roles. Here’s a simple example:
# Login to Azure Stack Hub environment
Connect-AzAccount -EnvironmentName “AzureStackUser”
# Assign a role to a user
New-AzRoleAssignment -SignInName [email protected] -RoleDefinitionName Contributor -Scope /subscriptions/{subscription-id}
Replace {subscription-id} with your subscription identifier and [email protected] with the email of the user you wish to assign the role to.
Assigning Roles Using Azure CLI
Similarly, you can utilize the Azure CLI for role assignments:
# Login to Azure Stack Hub environment
az login –profile 2019-03-01-hybrid
# Assign a role to a user
az role assignment create –assignee [email protected] –role Contributor –scope /subscriptions/{subscription-id}
Make sure to replace {subscription-id} and [email protected] accordingly.
Assigning Groups
Instead of assigning roles to individual users, it is often more efficient to assign roles to groups when multiple users require the same level of access.
Creating Groups in Azure Active Directory
To create groups in AAD, follow these steps:
- Access the Azure Active Directory admin center.
- Go to the “Groups” section and click on “New group”.
- Fill out the group information, including the group type and membership type.
- Add members to the group and save your changes.
After creating groups in AAD, you can assign roles to these groups in Azure Stack Hub using the same process as for individual users, specifying the group instead.
Considerations for AD FS
If you are using AD FS instead of AAD, the process for creating groups will depend on your local Active Directory setup. You’ll create the groups within AD and then assign them to roles within Azure Stack Hub through the administrator portal, Azure PowerShell, or Azure CLI.
Conclusion
Managing access via users and groups is critical for maintaining security and operational efficiency in Azure Stack Hub. Whether you are using the Azure Stack Hub Administrator Portal, Azure PowerShell, or Azure CLI, the process is streamlined and designed to align with Azure access control mechanisms. The use of RBAC allows for granular permission settings, and the leveraging of groups can simplify the process for larger organizations. Properly assigning users and groups ensures that the right personnel have the appropriate levels of access to resources in your Azure Stack Hub environment.
Practice Test with Explanation
True/False: In Azure Stack Hub, you can assign users to roles using Azure Active Directory (AAD) groups.
Correct Answer: True
Explanation: Azure Stack Hub supports role-based access control (RBAC), and roles can be assigned to users either directly or indirectly through membership in an AAD group.
True/False: You must have Global Administrator permissions in Azure AD to assign users and groups to roles in Azure Stack Hub.
Correct Answer: False
Explanation: To assign roles in Azure Stack Hub, you generally need to have the Owner or User Access Administrator role, not necessarily the Global Administrator in Azure AD.
