RADIUS 2FA

The Protectimus RADIUS 2FA solution can be used to enable two-factor authentication for any software or equipment that supports RADIUS authentication protocol.

The Protectimus RADIUS Server connector works as a RADIUS server. It transfers authentication requests from the RADIUS device to the Protectimus multi-factor authentication (MFA) server and returns the answer permitting or denying access.

Add two-factor authentication (2FA / MFA) to protect your VPN, Wi-Fi, and any other software or device that supports RADIUS. To do that, integrate with Protectimus Cloud MFA Service or On-Premise Platform via RADIUS authentication protocol.

The list of software and devices that can be integrated with Protectimus via RADIUS authentication protocol includes but is not limited to:

• Ubuntu;
• macOS;
• Cisco ACS / ISE / ISR / Catalyst / SSH Network Device Access;
• Citrix ADC (NetScaler ADC), Citrix Gateway (NetScaler Gateway), Citrix Virtual Desktops (XenDesktop), Citrix Virtual Apps (XenApp);
• VMware Horizon View (VDI), VMware Horizon Cloud DaaS (VDI), VMware vCenter Server;
• OpenVPN;
• Juniper and Pulse Secure SSL VPN;
• F5 BIG-IP VPN;
• Palo Alto IPSEC and SSL VPN;
• FortiGate VPN;
• Check Point Remote Access VPN;
• Huawei SSL VPN;
• UserGate VPN;
• Windows VPN;
• Mikrotik;
• SonicWALL TZ, NSA, Aventail series;
• Wi-Fi hotspots, etc.

The Protectimus RADIUS 2FA software is easy to set up. But if you have any questions, our team is always ready to help you with deploying RADIUS two-factor authentication (2FA) even in the most complex infrastructure. Get in touch with our support team here.

To integrate Protectimus 2FA solution with your RADIUS supporting device or software you need to set up and configure Protectimus RADIUS Server, and then configure the authentication policies on the device or application you want to add Protectimus 2FA to:

1. You allow the transmission of an authentication request over the RADIUS protocol to Protectimus RADIUS Server;
2. The Protectimus RADIUS Server component receives and processes the authentication request;
3. Then Protectimus RADIUS Server contacts the Protectimus authentication server to verify the one-time password entered by the user.

1. Install Protectimus RADIUS Server to enable RADIUS 2FA

1.1. Protectimus RADIUS Server Installation on any OS

java -jar radius.jar

or

java -jar radius.jar --spring.config.additional-location=radius.yml

1.2. Protectimus RADIUS Server Installation on Windows

1. Download the installer here.
2. Run the installer as administrator.
3. Check the RProxy checkbox.
   
   

   ATTENTION!
   If you plan to use the Protectimus On-Premise Platform, keep the Platform checkbox checked.
   If you plan to use the Protectimus SAAS Service, uncheck the Platform checkbox.

If you plan to use the Protectimus On-Premise Platform	If you use plan to use the Protectimus SAAS Service

4. Java (JDK 7 and above) must be installed on the machine, if not, it will be installed automatically, click Install.

5. When Java is installed, click Next.

6. Choose the folder to install the Protectimus components and click Install.

7. When the installation is complete, you’ll see this message.

2. Get Registered and Configure Basic Settings

1. Register with the Protectimus Cloud Service and activate API or the Protectimus On-Premise Platform.
2. Add Resource.
3. Add Users.
4. Add Tokens or activate Users’ Self Service Portal.
5. Assign Tokens to Users.
6. Assign Tokens with Users to the Resource.

3. Configure Protectimus RADIUS Server

The Protectimus RADIUS Server settings can be configured by specifying them in the radius.yml file, which must be located in the same directory as the executable.

Available properties that you should add to the radius.yml file include:

3.1. RADIUS Settings

radius:
    secret: secret
    auth-port: 1812
    listen-address: 0.0.0.0
    attributes:
        defaults:
            Service-Type: NAS-Prompt-User
        for-users:
            john:
                Service-Type: Login-User

secret:

auth-port:

listen-address:

attributes:

defaults:

for-users:

3.2. PROTECTIMUS API Settings (setting up connection to the PROTECTIMUS service )

protectimus-api:
    login: 
    api-key: 
    url: https://api.protectimus.com/
    resource-id:
    resource-name:

login:

api-key:

url:

resource-id:

resource-name:

3.3. LDAP Settings

ldap:
    base: dc=test,dc=com
    urls:
      - ldap://127.0.0.1:389
    principal-attribute: userPrincipalName
    custom-filter: (memberof=cn=managers,ou=groups,dc=test,dc=com)

base:

urls:

principal-attribute:

custom-filter:

3.4 Authentication Process Settings

auth:
    providers:
    re-enter-otp: true
      principal-normalization: true
      inline-mode:
        enabled: false
        separator: ''

providers:

re-enter-otp:

principal-normalization:

inline-mode:

3.5. An Example of radius.yml file

```yaml
radius:
  secret: secret

auth:
  providers:
    - LDAP
    - PROTECTIMUS_OTP

ldap:
  urls:
    - ldap://localhost:389
  base: dc=test,dc=com
  username: uid=admin,ou=readOnly
  password: secret
  principal-attribute: sAMAccountName

protectimus-api:
  login: [email protected]
  api-key: secret
  url: https://api.protectimus.com/
  resource-id: 1
```

In this case password would be authenticated with LDAP storage, and OTP with Protectimus MFA.

Now you need to configure your device or application to communicate with Protectimus RADIUS Server service over RADIUS protocol.
