Check Point Gateway Integration with AuthPoint

This document describes how to set up multi-factor authentication (MFA) for Check Point Gateway with AuthPoint.

You must configure and deploy the Check Point Gateway before you set up MFA with AuthPoint. The Check Point Gateway can be configured to support MFA in several modes. For this integration, we set up RADIUS authentication with AuthPoint.

This integration was tested with Check Point VSX Gateway R81.10.

Configure AuthPoint

Before AuthPoint can receive authentication requests from Check Point, you must specify the Check Point Gateway as a RADIUS client resource In AuthPoint, resources are the applications and services that your users connect to. in AuthPoint. You must also create an authentication policy Authentication policies specify which resources users can authenticate to and which authentication methods they can use (Push, QR code, and OTP). for the Check Point resource and you must bind the Check Point resource to the AuthPoint Gateway.

Add a RADIUS Resource in AuthPoint

From the AuthPoint management UI:

1. From the navigation menu, select Resources. Click Add Resource.
   The Add Resource page opens.

2. From the Type drop-down list, select RADIUS Client.
   Additional fields appear.

3. In the Name text box, type a descriptive name for the Check Point Gateway resource.
4. In the RADIUS Client Trusted IP or FQDN text box, type the IP address your RADIUS client uses to send RADIUS packets to the AuthPoint Gateway. This must be a private IP address. For Check Point, this is usually the internal IP address of your Check Point Gateway.
5. From the Value Sent for RADIUS Attribute 11 drop-down list, specify the value sent for attribute 11 (Filter-ID) in RADIUS responses. You can choose to send the AuthPoint group or Active Directory groups of the user.
6. In the Shared Secret text box, type the shared secret key. This is the password that the RADIUS server (AuthPoint Gateway) and the RADIUS client (Check Point) use to communicate.
7. Click Save.

Add a Group in AuthPoint

You must have at least one user group in AuthPoint to configure MFA. If you already have a group, you do not have to add another group.

To add a group to AuthPoint:

1. From the navigation menu, select Groups.
2. Click Add Group.
   The New Group page appears.

3. In the Name text box, type a descriptive name for the group.
4. (Optional) In the Description text box, type a description of the group.

5. Click Save.
   Your group is listed on the Groups page.

Add an Authentication Policy to AuthPoint

Authentication policies specify which resources users can authenticate to and which authentication methods they can use (Push, QR code, and OTP).

You must have at least one authentication policy in AuthPoint that includes the Check Point resource. If you already have authentication policies, you do not have to create a new authentication policy. You can add this resource to your existing authentication policies.

Users that do not have an authentication policy for a specific resource cannot authenticate to log in to that resource.

To configure an authentication policy:

1. From the navigation menu, select Authentication Policies.
   The Authentication Policies page opens.

2. Click Add Policy.
   The Add Policy page opens.

3. In the Name text box, type a name for this policy.
4. From the Select the Authentication Options drop-down list, select Authentication Options, then select which authentication options users can choose from when they authenticate.

   If you enable the push and OTP authentication methods for a policy, RADIUS client resources associated with that policy use push notifications to authenticate users.

   QR code authentication is not supported for RADIUS client resources.

5. From the Groups drop-down list, select which groups this policy applies to. You can select more than one group. To configure this policy to apply to all groups, select All Groups.
6. From the Resources drop-down list, select the resource that you created in the previous section. If you want this policy to apply to additional resources, select each resource this policy applies to. To configure this policy to apply to all resources, select All Resources.

7. (Optional) If you have configured policy objects such as a Network Location, select which policy objects apply to this policy. When you add a policy object to a policy, the policy only applies to user authentications that match the conditions of the policy objects. For example, if you add a Network Location to a policy, the policy only applies to user authentications that come from that Network Location. Users who only have a policy that includes a Network Location do not get access to the resource when they authenticate outside of that Network Location (because they do not have a policy that applies, not because authentication is denied).

   For RADIUS authentication, policies that have a Network Location do not apply because AuthPoint does not have the IP address of the user.

   If you configure policy objects, we recommend that you create a second policy for the same groups and resources without the policy objects. The policy with the policy objects should have a higher priority.

8. Click Save.
   Your policy is created and added to the end of the policy list.

   When you create a new policy, we recommend that you review the order of your policies. AuthPoint always adds new policies to the end of the policy list.

Bind the RADIUS Resource to a Gateway

To use RADIUS authentication with AuthPoint, you must have the AuthPoint Gateway installed on your corporate network and you must assign your RADIUS resources to the Gateway in the AuthPoint web UI. The Gateway functions as a RADIUS server.

If you have not configured and installed the AuthPoint Gateway, see About Gateways.

To assign your RADIUS resource to the gateway, from the AuthPoint web UI:

1. From the navigation menu, select Gateway.
2. Select the Name of the Gateway.

3. From the RADIUS section, in the Port text box, type the port number used to communicate with the Gateway. The default ports are 1812 and 1645.

   If you already have a RADIUS server installed that uses port 1812 or 1645, you must use a different port for the AuthPoint Gateway.

4. From the Select a RADIUS Resource drop-down list, select your RADIUS client resource.
5. Click Save.

Add Users to AuthPoint

Before you assign users to a group, you must add the users to AuthPoint. There are two ways to add AuthPoint user accounts:

• Sync users from an external user database
• Add local AuthPoint users

Each user must be a member of a group. You must add at least one group before you can add users to AuthPoint.

Test the Integration

To test the integration of AuthPoint and configuration of your Check Point Gateway, you can authenticate with a mobile token on your mobile device. For RADIUS resources, you can choose one-time password (OTP) or push. In this example, we use the one-time password authentication method.

To test the integration:

1. Start the Check Point Endpoint Security client application.
2. From the taskbar, right-click the VPN client icon, then select Connect To.
   The Authentication page opens.
   

If you see the The site's security certificated is not trusted warning, click Trust and Continue. You always see this warning when you create a new site for the first time.

3. From the Site drop-down list, select the Check Point Gateway External IP address.
4. In the Username text box, type your AuthPoint user name.
5. In the Password text box, type your AuthPoint password and your one-time password (OTP) from the AuthPoint mobile app. Do not add a space between your password and your OTP.

6. Click Connect.
   A virtual interface is assigned to your computer with an IP address on the 172.16.10.0/24 network.
