1.0 Introduction

The Cisco® Adaptive Security Appliances (ASA) enable remote and mobile employees, customers, and partners to gain secure access to corporate Virtual Private Network resources and applications. Providing secure access via a VPN over existing Internet connections requires strong, two-factor authentication to protect resources. The ActivIdentity solutions that work with Cisco incorporate SSL VPN solutions with versatile, strong authentication that is flexible, scalable, and simple to manage. ActivIdentity offers two solutions:

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

• ActivIdentity 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 ActivIdentity 4TRESS AS FT2011 Web soft token authentication with Cisco Adaptive Security Appliances. Use this handbook to enable authentication via a Web soft token for use with an SSL-protected Cisco VPN.

1.2 Prerequisites

• ActivIdentity 4TRESS Authentication Server FT2011.

• Cisco ASA version 8.x installed and configured.

• The Web soft token is configured to work with or without a PIN.

• Users have static LDAP passwords for access to the Self Help Desk to enroll Web tokens.

• The Cisco login page has been customized (illustrated in this handbook).

Getting Started

2.0 Cisco ASA Configuration

This chapter describes how to manage a Cisco ASA. When a user signs into a Cisco ASA appliance, the Cisco ASA forwards the user’s credentials to this authentication server to verify the user’s identity. You will create one authentication server (an ActivIdentity 4TRESS AS FT2011 RADIUS Server) to validate the user’s one-time password generated by a Web soft token.

2.1 Procedure 1: Create New Radius Server Instance

When using an external RADIUS server to authenticate Cisco ASA users, you must configure the server to recognize the Cisco ASA as a client and specify a shared secret for the RADIUS server to use to authenticate the client request.

To configure a connection to the RADIUS server on a Cisco ASA SSL VPN appliance and to define the RADIUS Server instance, perform the following steps.

1. In the ASDM console, navigate to Configuration-> Remote Access VPN -> AAA/Local User, and then click AAA Server Groups.

2. Click Add at the far right of the page displayed.

The nearby dialog is displayed.

3. Enter a Server Group name, and then select RADIUS for the Protocol.

4. Click OK.

Repeat the process to add a backup RADIUS server.

5. In the AAA Server Groups section, select the RADIUS server group you just created.

6. In the Servers in the Selected Group section, click Add next to the Server Name or IP Address line.

7. Enter the appropriate information for your configuration.

• Server Name or IP Address—Specify the name or IP address.

• Server Authentication Port—Enter the authentication port value for the RADIUS server.

Typically, this port is 1812.

• Server Shared Secret—Enter a string. You will also enter this string when configuring the RADIUS server to recognize the SA Series SSL VPN appliance as a client.

• Accept the other default settings.

8. Click OK. The RADIUS server is displayed in the Servers in the Selected Group section, as illustrated next.

2.4 Procedure 4: Configure New Cisco Portal

PIN usage is dependent on the custom page deployed. It is possible to hide the Web soft token, and in this case, it’s necessary to apply a Web soft token without use of a PIN. In this case, the PIN is replaced by the user’s LDAP password. Please contact your ActivIdentity technical representative to obtain a sample page and to discuss the following possible combinations of PIN usage:

• Username plus LDAP Password plus visible Web soft token plus PIN plus OTP generated by the Web soft token.

• Username plus LDAP Password plus visible Web soft token without PIN plus OTP generated by the Web soft token.

• Username plus LDAP Password plus hidden Web soft token without PIN plus OTP generated by the Web soft token hidden in the page.

• Username plus visible Web soft token plus PIN plus OTP generated by the Web soft token.

Your ActivIdentity technical contact will send you images, the token applet, and the login portal page. The portal page will be similar to the following illustration.

11. Click Save. A success message appears.

3.3 Configure Administration Groups, User Types, User Repositories, and Authentication

Policies

For details, refer to the ActivIdentity 4TRESS Authentication Appliance Administration Guide: Management Console technical documentation. This section summarizes the remaining procedures to perform before Web soft

tokens can be activated.

1. Use the ActivIdentity 4TRESS Management Console to create and update administration groups within user types. Then you can add users to the administration groups.

User types define categories of users. A hierarchy of administration groups exists for each user type.

For each user type, you can define:

• User repositories relating to the user type,

• Authentication policies accessible to users of this type, and

• User attributes for users of this type.

There are default user types. Installing the ActivIdentity 4TRESS Appliance Server automatically sets up a number of user types. For each user type, there are pre-defined system users. Collectively, these sample users have all the required privileges to administer the system. You can use the base data set as provided, or modify it to meet your specific requirements.

2. Map the user repository to a user type.

3. Assign an authentication policy to a user type.

4. Map the user repository to an administration group.

Administration groups provide a way to organize (partition) users for administrative purposes, as well as a way to assign permissions to users through membership of administration groups.
