Check Point Endpoint Security VPN Linux: Implementing Two-Factor Authentication

In today's digital landscape, security is a top priority for organizations. One effective way to ensure secure connectivity and compliance with an organization's security policy is by implementing two-factor authentication (2FA) for remote access connections. Check Point endpoint security provides a robust solution for securing remote computers and monitoring traffic targeted at VPN tunnels.

Configuring Remote Desktop Two-Factor Authentication

To set up 2FA for Check Point Remote Access VPN clients, you need to configure the Security Management Server and the VPN client settings. Here's a step-by-step guide on how to achieve this:

1. Create a new policy for Remote Access VPN users: Go to Security Policies > Policy and create a new policy for Remote Access VPN users.

2. Specify source of user data: Set the parameters for the new object, specifying the source of user data.

3. Configure RADIUS server: Select New > More > User > Access Role, then select a RADIUS server and specify the previously created object.

4. Set up 2FA using RADIUS (Multifactor): Use RADIUS (Multifactor) as both first and second factors. You can also use Username and Password as the first factor and RADIUS (Multifactor) as the second factor.

Configuring VPN Client Settings

To set up 2FA for Remote Access VPN clients, follow these steps:

1. Open Check Point Security Gateway object settings: Go to VPN Clients/Mobile Access > Authentication and open the Check Point Security Gateway object settings.

2. Configure Shared Secret and Host: Provide a value from the Multifactor Radius Adapter component settings for Shared Secret, and specify the address of the MultiFactor Radius Adapter component as the Host.

Setting up Remote Access VPN in Check Point

To set up 2FA, you need to install and configure the MultiFactor Radius Adapter component. This allows users to confirm their access requests with a selected Multifactor authentication method or one-time passcode in the Remote Access VPN client (Endpoint Security/MAB).

The user connects to the VPN, enters their login and password in the Remote Access client (VPN client list with 2FA support), and then receives a one-time passcode from an OTP application like Google Authenticator or Yandex. The Check Point NGFW checks the user's login and password in Active Directory or Network Policy Server and requests the second authentication factor.

Implementing two-factor authentication for Check Point Remote Access VPN client connections provides an additional layer of security, ensuring compliance with organization's security policy. By following these steps, you can set up 2FA using RADIUS (Multifactor) as both first and second factors, providing a robust solution for securing remote computers and monitoring traffic targeted at VPN tunnels.
