JumpCloud's solution can simplify the management of Azure Radius by consolidating multiple user identities into a single, unified platform.
This eliminates the need for multiple directory services and passwords, reducing administrative burdens and improving security.
With JumpCloud, organizations can manage their Azure Radius users from a single location, streamlining the onboarding and offboarding processes.
This can lead to significant time savings and reduced errors, allowing IT teams to focus on more strategic initiatives.
Getting Started
To start working with Azure Radius, you need to initialize a new environment. This involves creating a new directory and navigating into it, then running the command `rad int` to set up a local development environment.
The `rad int` command will create a new file called `app.bicep` where your application will be defined.
Azure Radius uses environments as landing zones for applications, and they determine how an application runs on a particular platform. Environments inherit settings from the environment, including the container runtime, configuration, and Recipes.
You can view all your app's resources and relationships using the `rad` CLI.
The `rad` CLI will display the application definition in JSON format, showing you the Universal Control Plane ID, location, environment, and compute platform.
Here are the key properties you'll see in the application definition:
- The id property is the Universal Control Plane ID of the application.
- The location is where your Application resides.
- The environment specifies the Radius Environment that the Applications will bind to at deployment.
- Finally, compute specifies the hosting platform where running services in the Application will run.
To deploy your application, you'll use the `rad` CLI with the `deploy` command.
Azure Radius Setup
Azure Radius Setup is a crucial step in implementing Azure Multi-Factor Authentication.
You'll need to configure your appliance or server to authenticate via RADIUS to the Azure Multi-Factor Authentication Server's IP address, which will act as the RADIUS server.
The shared secret configured above is also essential for this step. You'll need to use the same shared secret to authenticate the RADIUS client.
To ensure a smooth authentication process, configure the RADIUS timeout to 30-60 seconds. This allows time to validate the user's credentials, perform multi-factor authentication, receive their response, and then respond to the RADIUS access request.
Here are the key RADIUS client configuration guidelines:
- Configure your appliance/server to authenticate via RADIUS to the Azure Multi-Factor Authentication Server’s IP address.
- Use the same shared secret that was configured above.
- Configure the RADIUS timeout to 30-60 seconds.
Security and Authentication
The Azure Multi-Factor Authentication Server acts as a RADIUS server and is inserted between your RADIUS client and your authentication target, adding Azure Multi-Factor Authentication to the process.
To function, you must configure the Azure Multi-Factor Authentication Server so it can communicate with both the client servers and the authentication target. The entire authentication will succeed only if both the primary authentication and the Azure Multi-Factor Authentication succeed.
The MFA Server only supports PAP and MSCHAPv2 RADIUS protocols when acting as a RADIUS server, so you won't be able to use other protocols like EAP in this configuration.
Multi-Factor Authentication Server
The Multi-Factor Authentication Server plays a crucial role in adding an extra layer of security to your authentication process. It acts as a RADIUS server, sitting between your RADIUS client and authentication target, such as Active Directory or an LDAP directory.
To function, the Azure Multi-Factor Authentication Server must be configured to communicate with both the client servers and the authentication target. This allows it to accept requests from a RADIUS client, validate credentials against the authentication target, and add Azure Multi-Factor Authentication to the process.
The MFA Server only supports PAP and MSCHAPv2 RADIUS protocols when acting as a RADIUS server. This means other protocols, such as EAP, can only be used when the MFA server acts as a RADIUS proxy to another RADIUS server that supports those protocols.
The use of other protocols in this configuration can limit the functionality of one-way SMS and OATH tokens, which won't work since the MFA Server can't initiate a successful RADIUS Challenge response using those protocols.
JumpCloud with AD
JumpCloud's Cloud RADIUS solution can be deployed in minutes, enabling secure user access to WiFi and VPN resources using existing Azure AD credentials.
This integration provides a seamless experience for users, allowing them to use their established Azure AD login to authenticate to RADIUS resources, eliminating the need to remember multiple passwords.
Admins can also leverage Azure AD's SCIM integration to import users to JumpCloud, streamlining the user provisioning process and ensuring that any changes made in Azure AD are automatically synchronized to JumpCloud.
JumpCloud's cloud RADIUS solution offers consolidated password management, eliminating the need for users to create additional passwords, which saves admins time and improves productivity.
With JumpCloud Cloud RADIUS, admins can segment their IT network into multiple virtual networks using VLAN tagging, enhancing network security and optimizing performance.
Here are the key benefits of using JumpCloud with AD:
- Easy authentication
- Consolidated password management
- Secure access
- Easy user provisioning
- VLAN tagging
What Are the Challenges of?
The challenges of RADIUS with Azure AD are numerous. It requires admins to set up a Windows Network Policy Server (NPS) on-prem that can act as a RADIUS server, which involves a series of complex steps including installing and provisioning the server, configuring policies, managing user access to the RADIUS server, and ongoing maintenance of the server.
This creates a tremendous workload for admins and adds costs as they must manage a hybrid model of cloud + on-prem environments. The process is so complex that it's not surprising many admins struggle with it.
Installing and provisioning the server, configuring policies, managing user access to the RADIUS server, and ongoing maintenance of the server are just some of the tasks that admins must handle. These tasks require a significant amount of time and resources.
A better option for admins would be to use a dedicated cloud RADIUS service provider. However, this approach also adds additional complexity.
The complexity of managing user identities and their passwords across both the traditional Azure AD environment and in the cloud RADIUS solution itself can be overwhelming. It requires IT admins to manage user identities and passwords in two separate environments.
This can lead to administrative support costs as well as costs associated with compliance and audit, as passwords are managed in two different environments.
