When you register an application in Azure Active Directory (Azure AD), you always need to configure the app registration permission scopes. This is an essential security aspect for Azure-based applications. This post will focus on how to configure app registration permission scopes related to the AZ-500: Microsoft Azure Security Technologies exam.
Understanding Permission Scopes
Permission scopes facilitate fine-grained access control, allowing your apps to ask for specific scope levels. Depending on your particular use case, you define different permission scopes using the “Expose an API” section in the Azure portal.
These permission scopes can either represent a user’s delegated permissions or an application’s application permissions. Delegated permissions are used by apps that have a signed-in user present in their background. Application permissions are suited to apps that run as background services or daemons sans any signed-in user.
For example, suppose you own an app, and you want it to be able to read calendars in your organization. You would grant it the “Calendars.Read” permission.
Steps for Configuring App Registration Permission Scopes
To configure the application registration permission scopes, first, you will have to register your application with Azure AD. Here are the steps to do it.
- Sign in to the Azure portal.
- In the left-hand navigation pane, select the Azure Active Directory service, then select App registrations > New registration.
- After you have registered your application, select Expose an API under Manage.
- In the User consent section, select Add a scope.
- In the panel that appears, start defining your scope.
Configuring User Delegated Permissions
To protect your users’ data, Microsoft identities granted delegated permission can access resources only in the context of a user:
{
"type": "User",
"userConsentDescription": "Allow the application to access the data on your behalf.",
"userConsentDisplayName": "Access data on your behalf",
"value": "user_impersonation"
}
Configuring Application Permissions
Application permissions belong to applications that run without a signed-in user present:
{
"type": "Admin",
"adminConsentDescription": "Allow the app to access data on your behalf.",
"adminConsentDisplayName": "Access data on your behalf",
"value": "data.readwrite.all"
}
Once you provide these details, click “Add Scope” to register a new permission scope for your API.
Conclusion
In conclusion, understanding and configuring app registration permission scopes in Azure AD is a vital part of security protocol for Azure applications. This will ensure the security and integrity of the data your app deals with while limiting access only to the necessary resources.
Remember, Microsoft Azure Security Technologies exam (AZ-500) requires a deep understanding of Azure security infrastructure, including topics such as app registration permission scopes. Therefore, understanding this topic is crucial for passing the AZ-500 exam.
Practice configuring scopes for your applications and refine your skill as it forms an important aspect of the AZ-500 exam. It’s crucial to correctly set the scope, whether it is for user delegated permissions or for application permissions. Happy learning and all the best for your exam!

Interview Questions
What is an “app registration” in Microsoft Azure?
App registration in Azure refers to the process of registering an application in the Azure Active Directory (Azure AD). This process allows for the setting up of authentication and configuration of permissions for the application to access other resources on the network.
What are permission scopes in Azure App registration?
Permission scopes in Azure App registration define the permissions that an application needs to access various resources or services in an Azure AD environment.
What is the purpose of the ‘Add a permission’ button in Azure app registration?
The ‘Add a permission’ button allows you to add specific permissions for your application to access APIs and services. These could be Microsoft APIs, or your own APIs.
What are the two types of permissions supported in Microsoft Azure AD?
Microsoft Azure AD supports two types of permissions: Delegated permissions and Application permissions. Delegated permissions are used by apps that access data on behalf of a user, while the Application permissions are used by apps that run without a user present.
In Azure AD, what is the difference between ‘Delegated Permissions’ and ‘Application Permissions’?
Delegated Permissions are those that an app needs to work on behalf of the user, meaning the user is present, and they need to give consent. Application permissions are those required by applications that need to run in the background without a user presence and are typically consented to by an administrator.
What does the ‘Grant admin consent for {directory}’ button do in Azure AD application registration?
The ‘Grant admin consent for {directory}’ button is used to grant all users within a specific directory the ability to use the application or perform the operation.
What is an Implicit grant flow in Azure AD?
The Implicit grant flow is a simplified authorization protocol from the OAuth 2.0 specification. It is designed for applications where only a token is required for asking resources & information, like Single Page Applications (SPAs).
What are the steps to set up or configure application permission scopes in Azure AD?
To configure application permissions scopes in Azure AD, you need to follow these steps:
– Register the application in Azure AD
– Specify the API permissions that the app requires
– Grant admin consent to the permission scopes you’ve chosen.
What is the ‘Expose an API’ section in Azure App registration?
The ‘Expose an API’ section allows developers to define the Application ID URI for the App service, and here newly created custom scopes or permissions can also be added.
Is it possible to restrict the permission scopes for certain apps in Azure AD?
Yes, it is possible to restrict permission scopes for certain apps in Azure AD. This can be done through the application’s manifest file by setting the ‘requiredResourceAccess’ field.
Can an Azure AD end-user grant permissions to apps?
Yes, but only if the permissions required by the app are part of the “User consent permissions” category. If the app requires permissions from the “Admin consent permissions” category, only an administrator can grant these permissions.
How can you remove permissions from an App registration in Azure AD?
In Azure AD, you can remove permissions from an app by navigating to the “API Permissions” of the app registration and then removing the specific permission.
What happens if a necessary permission is not granted to an app in Azure AD?
If the necessary permissions are not granted to an app, the app might not function correctly as it may lack the ability to access the resources or perform the actions necessary for its operation.
What does ‘Consent’ mean in terms of Azure AD app permissions?
‘Consent’ in Azure AD means that the user or administrator approves the permissions requested by the app. This includes both delegated and application permissions.
Can an Azure AD guest user provide consent to an app?
No, guest users cannot provide consent to an app. Only a global administrator can grant consent to an app on behalf of all users in an Azure AD tenant. The admin can either provide consent to all apps or a specific list of apps.
