Described within Microsoft’s official documentation, this task forms a critical part of effective cloud-based identity and access management. With Azure, different levels of access can be assigned to users, groups, and apps across subscription, management groups, resource groups, and resources themselves. These are often referred to as “scope levels”.
Understanding Azure Roles
Azure roles are defined by a set of permissions that determine what actions can be performed in Azure. For instance, a user assigned with the “Reader” role can view existing resources within the Azure portal, though they can’t modify those resources. The role of “Contributor”, however, allows a user to manage all resources but does not permit them to grant access to other users. Meanwhile, the “User Access Administrator” role allows a user to manage user access to Azure resources.
For better control, custom roles can also be created to meet specific organizational requirements. These roles can combine any collection of actions you’d like to group together. Each role has a list of actions, not actions, and data actions that respectively show what is allowed and disallowed.
Assigning Azure Roles
Assigning Azure roles requires that you have access to the Azure portal with the appropriate permissions. Microsoft documentation outlines three methods to assign Azure Roles, which are through the Azure portal, Azure CLI, and PowerShell.
Here’s an example of how to assign a role in the Azure portal, following the documentation:
- In Azure portal, select ‘All services’ and search for ‘Subscriptions’.
- Access the subscription over which you have ownership.
- Choose the ‘Access control (IAM)’.
- Click on the ‘+Add’ button and select ‘Add role assignment’.
- In the ‘Add role assignment’ pane, select the role you wish to assign from the ‘Role’ dropdown menu.
- Select a ‘Member type’, choose the name of the user, group, or application to assign the role to.
- Finally, confirm the assignment by clicking the ‘Save’ button.
Azure CLI and PowerShell are more programming-oriented ways to assign roles. You’d want to refer to Microsoft’s documentation for specific commands and syntax.
It’s wise to note that changes after assigning roles might take a while to propagate and apply across the system. This delay often ranges from 5 to 10 minutes.
Comparing Azure Roles
One can compare Azure roles using Azure’s built-in role comparison feature. By navigating to the ‘All services’ in Azure, search for ‘Subscriptions’. Once selected, go to ‘Access control (IAM)’, then ‘Roles’. Here, you can select multiple roles and use the ‘Compare’ option at the top of the list to provide a side-by-side comparison of the selected roles.
Use tables to list out the permissions and restrictions of each role to provide a clearer picture.
By mastering Azure roles and their assignment throughout your organization’s hierarchy, you’ll hone an essential skill for the SC-300 exam. Understanding the larger picture of Azure’s robust role-based access control system will also aid you in developing secure and efficient cloud management strategies.
