At the heart of managing API permissions is Role-Based Access Control (RBAC). RBAC provides fine-grained access management for Azure. Permissions are assigned through roles, which define what actions a user, group, or service can perform on a resource.
RBAC includes several built-in roles:
Additional roles are available and custom roles can be created for specific needs.
Let’s say you have a team responsible for managing virtual machines in a specific subscription. You would:
For applications that need to access or modify resources, Azure provides Managed Identities. These identities allow you to authenticate to any service that supports Azure AD authentication without embedding credentials in your code.
There are two types of Managed Identities:
An Azure Function needs to read from a storage account:
Conditional Access policies can help secure API access by applying the right access controls when needed. These policies can be based on certain conditions, such as the user’s role, location, or device state.
You want to ensure that only users from your corporate network can manage resources:
Azure AD PIM enhances security by managing, controlling, and monitoring access within Azure AD, Azure, and other Microsoft Online Services. It introduces the concept of ‘just-in-time’ access.
For a critical role such as the ‘User Access Administrator’, rather than giving permanent access:
Permissions can be granted at different levels in Azure hierarchy:
Level | Scope | Common Use |
---|---|---|
Management Group | Collections of subscriptions | Apply policies at a large scale |
Subscription | All resources in a subscription | Delegate administrative control |
Resource Group | Resources sharing the same lifecycle | Manage group of resources together |
Resource | Individual Azure resource | Granular control over a single resource |
For a user who needs read-only access to network resources in a single resource group:
Managing API permissions to Azure subscriptions and resources is crucial to maintain a robust security posture. Utilizing RBAC, Managed Identities, Conditional Access, and PIM provides you with a comprehensive set of tools to effectively control and monitor access to your Azure environment, an essential skill for the AZ-500 Microsoft Azure Security Technologies exam.
Answer: False
Explanation: API permissions are required for service principals to interact with Azure resources on behalf of applications or users.
Answer: False
Explanation: Azure RBAC can control access at multiple levels including the subscription, resource group, and resource levels.
Answer: D) All of the above
Explanation: Contributor, Reader, and Owner are all built-in roles in Azure RBAC that define a set of permissions.
Answer: True
Explanation: Custom roles can be created to provide specific permissions that are not covered by built-in roles.
Answer: False
Explanation: Permissions can be changed, added, or removed at any time by users with sufficient privileges.
Answer: A) API access without needing credentials
Explanation: Managed Identities in Azure provide an identity for applications to use when accessing other Azure resources, eliminating the need for credentials in code.
Answer: False
Explanation: Azure Active Directory (Azure AD) plays a central role in managing user and application access to resources through authentication and authorization.
Answer: B) They are used to grant access to Azure resources.
D) They have credentials that can be used to authenticate applications.
Explanation: Service principals are Azure AD objects that represent applications or service identities for authorization purposes, not users or subscriptions.
Answer: D) All of the above
Explanation: Azure Policy, Azure Portal, and Azure CLI can all be used to automate and manage API permissions at scale in various ways.
Answer: False
Explanation: Roles can be assigned not only to users but also to groups, service principals, and managed identities.
Answer: B) Access Control (IAM)
Explanation: Azure’s Access Control (IAM) feature allows for the assignment of granular permissions to specific operations within Azure resources.
Answer: False
Explanation: The principle of least privilege is a security best practice applicable in Azure, ensuring users and applications have only the permissions necessary to perform their tasks.
Microsoft Graph API is a set of REST APIs that allow developers to access data from various Microsoft services, such as Office 365, Azure Active Directory, and Windows 10.
The v1 endpoint uses the OAuth 2.0 protocol with Azure Active Directory (Azure AD) authentication, while the v2 endpoint supports both OAuth 2.0 and OpenID Connect (OIDC) protocols for authentication.
User authentication is the process by which users prove their identity to Azure AD, which then provides them access to resources in your organization.
App authentication is the process by which an application proves its identity to Azure AD, which then provides it access to resources in your organization.
User authentication is for users who need access to resources in your organization, while app authentication is for applications that need access to resources in your organization.
The different authentication flows in Azure AD for app scenarios are authorization code flow, implicit grant flow, device code flow, and client credentials flow.
The authorization code flow is a secure and recommended way of obtaining user authorization to access resources in Azure AD.
The implicit grant flow is a simplified way of obtaining user authorization to access resources in Azure AD.
The device code flow is a way for applications to obtain user authorization to access resources on devices that don’t have a web browser.
The client credentials flow is a way for applications to authenticate with Azure AD using only their client ID and client secret, and not a user’s credentials.
