Two Factor Authentication - 2FA for VMWare Horizon Air

---

VMware Horizon Air is a desktop and application delivery platform that allows administrators to deploy cloud-based virtual applications and desktops to end users on any device.

What is Virtual Desktop Infrastructure (VDI) & Why VDI Security Solutions important?

VDI is a desktop-centric service that hosts user desktop environments on remote servers and storage systems, which are accessed over a network using a remote display protocol. Enterprises are converting physical desktops to Virtual Desktop Infrastructure (VDI) since it provides efficient hardware utilization and centralized management while reducing costs.

Due to the COVID-19, many companies need to find some ways to enable remote working. VDI solution is one of their choices. VMWare Horizon Air can provide a quick win VDI solution but it still need to spend efforts to setup for some authentications and security settings, e.g. MFA. For some SME companies, they may not have their own RADIUS (Remote Authentication Dial-In User Service) server and OTP (one-time password) server to enable 2FA/MFA. miniOrange provides a ready to use Two-Factor Authentication - 2FA solution for VMWare Horizon Air VDI using RADIUS Server which enables an extra layer of authentication to VDI logins & ensures that you roll out secure access to your employees within minutes.

To use miniOrange Two-FActor Authentication (2FA) you can enable RADIUS authentication in VMWare Horizon Air and configure policies in miniOrange to enable or disable 2FA for users.

Types of 2FA Authentication with RADIUS

The 2-factor authentication can be of two types depending on the Application.

• Applications that support RADIUS Challenge.
• Applications that do not support RADIUS Challenge.

In Applications that support RADIUS Challenge :

• First step is user's username & password get validated against the credentials stored in Active Directory and 2nd request sends a success response, this request is sent to validate the 2-factor authentication of the user, on successful authentication user is granted access to the application.
• Authentication methods : All Authentication methods are supported by miniOrange. Software Token, Push Notification, OTP over Email to name a few.

Enable Two-Factor Authentication (2FA) for VMWare Horizon Air VDI to increase security level.

1. Add Radius Client in miniOrange

• Login into miniOrange Admin Console.
• Go to Apps and click on Add Application button on the top right corner.



• Choose RADIUS as Application type and click on Create App button.



• Click on VMWare Horizon Air application tab. If you don't find your application click on Radius Client application tab.



• Configure details below to add Radius Client.

Client Name:	Any name for your reference.
Client IP:	IP address of VPN server which will send Radius authentication request.
Shared Secret:	Security key. For Eg. "sharedsecret" (Keep this with you, you will need to configure same on VPN Server).

Group Name:	Group for which the policy will apply.
Policy Name:	Any Identifier that specifies policy name.
Login Method	Login Method for the users associated with this policy.

• Click on Save.


NOTE: For On-Premise version follow the below steps before testing the connectivity.



Only For On-Premise Version

Step 1: Open Firewall Ports.

• In order to receive the RADIUS request, it is necessary to open UDP traffic on ports 1812 and 1813 for the machine where On-Premise IdP is deployed.
• If the hosting machine is a Windows Machine then you can follow this document.
• If the hosting machine is a Linux Machine then you can follow this document.

NOTE: If your machine is hosted on AWS, then enable the ports from the AWS panel.

2. Configure VMWare Horizon Air

• Login to your VMWare Horizon Air dashboard and go to RADIUS Server Settings.
• Fill the details as mentioned below:

Label	The name of this configuration. Eg:miniOrange Radius
Hostname/Address	For on-premise version: IP of server where IDP(miniOrange) is installed For cloud version: Contact us at info@xecurify.com to get the IP
Authentication Port	Enter 1812 (or whichever port configured on your miniOrange Authentication Proxy).
Authentication type	Must be PAP.
Shared secret code	Enter the Shared secret that we used to configure RADIUS app in miniOrange IDP. In step 1 we configured the shared secret as "sharedsecret"
Server timeout (in seconds)	Increase the timeout to 90 seconds.
Max attempts	Number of times to send authentication request. Must be 1.

• Click Save.

3. Configure 2FA for End-Users

• Login into End-User Dashboard using Default User Directory credentials..
• Select Configure 2FA from left panel.



• Browse through the Second factor options and choose an appropriate method to be used by end user during login.
• For now, we have selected the "OTP OVER SMS"as our 2FA method. You can explore the guide to setup other 2FA methods.
• Enable the OTP over SMS if you have your phone number added under your profile section else click on Edit button.

4. Configure Your User Directory (Optional)

miniOrange provides user authentication from various external sources, which can be Directories (like ADFS, Microsoft Active Directory, Microsoft Entra ID, OpenLDAP, Google, AWS Cognito etc), Identity Providers (like Okta, Shibboleth, Ping, OneLogin, KeyCloak), Databases (like MySQL, Maria DB, PostgreSQL) and many more. You can configure your existing directory/user store or add users in miniOrange.

• Setup miniOrange as IDP
• Setup AD as User Directory
• Setup External IDP

• To add your users in miniOrange there are 2 ways:

1. Create User in miniOrange

2. Bulk Upload Users

1. Create User in miniOrange

• Click on Users >> User List >> Add User.



• Here, fill the user details without the password and then click on the Create User button.



• After successful user creation a notification message "An end user is added successfully" will be displayed at the top of the dashboard.
