Azure B2C - restricting admins!
Hi
Hope someone can help. How would I restrict admin access in an Azure B2C tenant? Azure B2C does not have admin units. If an admin signs in, it would seem that with 'user admin' rights they can alter accounts across the directory. Can this be restricted?
In Azure AD B2C (Azure Active Directory Business to Consumer), there are no built-in "admin units" or granular administrative roles as you might find in Azure Active Directory (Azure AD). Azure B2C is designed primarily for customer-facing applications and identity management, and it does not have the same level of administrative control as Azure AD.
That said, there are some ways to restrict admin access and permissions in an Azure B2C tenant:
1. Custom Roles: While Azure B2C doesn't have predefined admin roles, you can create custom roles with specific permissions. For example, you can define a custom role that allows users to manage user accounts but not perform other administrative tasks. You can use Azure RBAC (Role-Based Access Control) to assign these custom roles to users. Keep in mind that custom roles require an Azure AD Premium P2 license.
2. Conditional Access: You can use Azure AD Conditional Access policies to control and restrict access to Azure B2C resources based on conditions such as location, device, or user attributes. For example, you can create a conditional access policy that only allows certain users to access Azure B2C resources and restricts administrative access to specific conditions.
3. Multi-Factor Authentication (MFA) : Enforce multi-factor authentication for administrators to add an extra layer of security. Even if an admin's credentials are compromised, MFA can help prevent unauthorized access.
4. Privileged Identity Management (PIM😞 While PIM is typically associated with Azure AD, it can also be used to manage privileged access to Azure B2C resources. You can use PIM to assign and manage "just-in-time" administrative access, requiring users to activate their admin role for a limited time.
5. Separate Tenants: Consider using separate Azure AD B2C tenants for different environments or applications. This way, you can isolate administrative access to specific tenants and limit the impact of any unauthorized changes.
6. Audit Logging: Enable Azure AD B2C audit logging to track changes and access to your tenant. This can help you monitor and investigate any suspicious activities.
7. Regularly Review Permissions: Periodically review the permissions assigned to users in your Azure B2C tenant and remove unnecessary access. Ensure that only trusted individuals have admin rights.
8. Alerting: Set up alerting and monitoring for critical actions within your Azure B2C tenant. This can help you detect and respond to unauthorized changes quickly.
It's important to strike a balance between security and usability when implementing access controls in Azure B2C. You want to restrict access to sensitive resources while ensuring that authorized administrators can perform their necessary tasks. Consider your organization's specific requirements and compliance standards when implementing these controls.
