Azure Active Directory (Azure AD) is Microsoft’s multi-tenant, cloud-based directory, and identity management service that combines core directory services, application access management, and identity protection into a single solution. Azure AD also offers a rich, standards-based platform that allows developers to deliver access control to their applications, based on centralized policy and rules.
In the context of the SC-300 Microsoft Identity and Access Administrator exam, understanding Azure AD role permissions is crucial. Azure AD role-based access control (RBAC) enables granular access management of Azure resources. This lets admins and users only manage the resources they need to, according to their role, hence limiting the risk of over-privileged users.
Azure AD Role-based Access Control (RBAC)
Azure AD RBAC involves three primary components: security principals, Azure Active Directory roles, and scopes.
- Security principal: Essentially the ‘who’ in Azure AD RBAC. A security principal could be a user, group, or application service principal.
- Role definitions: A role definition is a collection of permissions. It’s the ‘what’ in Azure AD RBAC. An example could be a database read permission, or a virtual machine write permission.
- Scopes: Scopes define the ‘where’ in Azure AD RBAC. They limit the extent of the role assignment, which could be at the management group, subscription, resource group, or resource level.
The relationship between these components can be represented as:
Security principal(Who) (Assigned with) Role(What) (At) Scope(Where)
Let’s consider an example scenario. If AdminA is assigned the ‘Virtual Machine Contributor’ role at the ‘Subscription1’ scope, they could start, stop, or delete any virtual machine within ‘Subscription1’ but would not have access to other subscriptions or resources.
Analyzing Azure AD Role Permissions
Each role within Azure AD has a set of permissions that is designed to have the least privilege necessary to perform its tasks. It’s crucial to examine these role permissions regularly to ensure proper security management.
Azure portal provides an intuitive interface to view and analyze the permissions associated with a particular role.
To analyze Azure AD role permissions, follow the steps below:
- Log into the Azure portal.
- Navigate to Azure Active Directory > Roles and administrators.
- Select a role, and you will find the list of permissions associated with that role.
Azure Managed Roles and Custom Roles
Azure AD provides several built-in roles that cover some of the most common user scenarios. Some of these built-in roles include Global administrator, User administrator, Directory readers, and more.
Each of these roles has specific permissions assigned. For instance, the ‘User administrator’ role can delete users, reset user passwords, and manage licenses, among other tasks, while the ‘Directory readers’ role only has permission to read directory information.
However, these built-in roles may not meet all your organization’s needs. Also, they may provide more grants than necessary for some tasks. To solve this issue, Azure AD allows you to create custom roles.
Custom roles can be created by duplicating an existing role and then modifying it, or by creating a new role from scratch and defining its permissions. Custom roles can be assigned at different scopes based on your needs.
Like built-in roles, custom roles must be carefully analyzed to avoid over-provisioning or under-provisioning permissions for a particular role.
In conclusion, understanding and analyzing Azure AD role permissions is a crucial component of Microsoft’s identity and access management. By correctly using and managing these roles and their permissions, you can build a secure and efficient access management system in accordance with principle of least privilege, thereby reducing your organization’s risk profile. While preparing for the SC-300 Microsoft Identity and Access Administrator exam, be sure to delve deep into this topic for a well-rounded understanding of how Azure enables robust identity and access management.

Interview Questions
What is an Azure AD role?
An Azure AD role is a set of permissions and rights that determine what actions users can perform within the Azure Active Directory. It can be used to manage resources at various scopes.
How can you assign Azure AD role permissions to a user or group?
Azure AD role permissions can be assigned to a user or group through the Azure portal, using PowerShell, or through the command line interface. The specific steps to assign permissions will depend on the method chosen.
What are some common Azure AD role permissions?
Some common Azure AD role permissions include User Administrator, Password Administrator, Security Administrator, Global Administrator, and Application Administrator.
What permissions does the Global Administrator role in Azure AD have?
The Global Administrator in Azure AD has full access to all administrative features. This includes managing users, groups, applications, domains, and directory settings.
Can you customize Azure AD role permissions?
Yes, custom roles in Azure AD can be created for more granular control. You can customize permissions to fit just about any scenario and they can be tailored to both broad and specific administrative duties.
What is the benefit of using custom roles for Azure AD role permissions?
Custom roles allow organizations to grant exactly the permissions that are necessary for someone to do their job – nothing more, nothing less. This can increase security and reduce risk by minimally exposed resources and limiting possible damage from compromised accounts.
How many Azure AD custom roles can be created per tenant?
You can have up to 5,000 custom roles per tenant in Azure AD.
What is the principle of least privilege (POLP) in relation to Azure AD role permissions?
The principle of least privilege (POLP) involves giving a user account or process the least amount of access necessary to perform its job. By assigning just the permissions that are absolutely needed for a job, you’re minimizing the risk of a security breach.
What Azure AD role is required to assign roles to other users?
The User Administrator or Global Administrator role in Azure AD is required to assign roles to other users.
Can user with the User Administrator role change a Global Administrator’s password in Azure AD?
No, a user with a User Administrator role cannot change a Global Administrator’s password. This level of control is restricted to higher permissions to protect the security of high-level accounts.
