4TRESS AAA Out-of-Band Authentication (SMS) and SSL VPN Fortinet | Integration Handbook

1.0 Introduction

FortiGate® appliances provide enterprise-class protection against network, content, and application-level threats for any deployment, from small offices to large enterprises, service providers, and carriers. Providing secure access via a VPN over existing Internet connections requires strong, two-factor authentication to protect resources. The HID Global Identity Assurance™ solutions that work with FortiGate appliances incorporate SSL VPN solutions with versatile, strong authentication that is flexible, scalable, and simple to manage. There are two solutions:

• 4TRESS AAA Server for Remote Access—Addresses the security risks associated with a mobile workforce remotely accessing systems and data.

• 4TRESS Authentication Server (AS)—Offers support for multiple authentication methods that are useful for diverse audiences across a variety of service channels (SAML, RADIUS, etc.), including user name and password, mobile and PC soft tokens, one-time passwords, and transparent Web soft tokens.

1.1 Scope of Document

This document explains how to set up 4TRESS AAA Web token authentication with FortiGate solutions. Use this handbook to enable out-of-band authentication when using an SSL-protected FortiGate VPN.

1.2 Prerequisites

• The 4TRESS AAA Server is up-to-date (v6.7) with LDAP users and groups already configured.

User Group > User Group.

2. Click Create New. The following dialog is displayed.

4TRESS AAA Out-of-Band Authentication (SMS) and SSL VPN Fortinet | Integration Handbook

Note: In any firewall user group, you can enable SSL VPN access and select the Web portal that the users can access. When the user connects to the FortiGate unit via HTTPS on the SSL VPN port (default 10443), the FortiGate unit requests a username and password.

3. To add a new remote authentication server, click Add. The Remote Server drop-down list appears, along with information about the Group Name.

4. Use the Group Name field to configure group name(s) to be added as identities who can be authenticated.

GROUP NAME OPTIONS:

• In the Group Name field, select Any to match all possible groups.

• In the Group Name field, select Specify, and then enter the group name in the appropriate format for

the type of server (RADIUS).

• You must specify at least one group name. The group name is the name of the group on the RADIUS server.

• If you want to specify more than one group name, then use a comma to separate the names.

• Important: When you specify a group name or names, you must use a specific RADIUS

dictionary on the AAA Server and also create an authorization profile. For more information on this topic, refer to the guide named 4TRESS_AAA_AdminGuide.pdf, specifically the section called Create a New RADIUS Authorization Profile.

• Also refer to the following vendor-specific requirements.
