5 CRYPTOCard Migration Agent Overview This document presents an overview of the CRYPTOCard Migration Agent and necessary steps to configure RADIUS proxy authentication. In this document we will show you: What the CRYPTOCard Migration Agent is and how it works How to implement the Agent within your network Steps to take to re-configure your existing Authentication server Steps to take to add CRYPTO-MAs to your network How to diagnose potential installation problems The CRYPTOCard Migration Agent is a freely distributed application which allows ANY RADIUS based device or application to communicate with both an existing Authentication server and CRYPTOCard s Passwords-as-a-Service solution CRYPTO-MAS within the same access network. The purpose of the Agent is to provide a low-investment, controlled and interruption free migration from a 3 rd party authentication server, such as RSA Authentication Manager, to CRYPTO-MAS. It allows both authentication solutions to work in parallel so that CRYPTO-MAS can gradually replace the existing authentication server as the primary server reducing the need for a wholesale change of existing tokens, instead allowing for the replacement of tokens when either faulty or at the end of the license period. The CRYPTOCard Migration Agent leverages RADIUS components of IAS on Windows Server 2003 or NPS on a Windows Server The agent intercepts RADIUS requests from the access device/application and handles all of the authentication processes with the existing authentication server and CRYPTO-MAS. To enable the CRYPTOCard Migration Agent to accept RADIUS authentication requests you must: Have either the Windows IAS or NPS Windows component installed within your network Install the CRYPTOCard Migration Agent on the machine that is hosting IAS or NPS. Enable RADIUS authentication on the existing server your service provider will help you achieve this. All servers are likely to have this capability, but it may not be enabled as some vendors recommend the use of proprietary protocols. RADIUS is an industry standard protocol and if a change is required it will not result in the loss of critical authentication functionality. In the diagram below, we can see the existing authentication server continues as the primary authentication server, while CRYPTO-MAS is added to the network to act as the secondary authentication server.

6 Figure 1 CRYPTOCard Migration Agent With the CRYPTOCard Migration Agent acting as an intermediate authentication server, the authenticated connection sequence would be as follows: 1. RADIUS requests received by Microsoft IAS/NPS from devices such as VPNs, Firewalls and other RADIUS Clients such as web applications are passed to the CRYPTOCard Migration Agent. The CRYPTOCard Migration Agent forwards the RADIUS authentication request to its Primary RADIUS Server entry (e.g.: RSA, VASCO, Aladdin, et al). 2. If the user credentials are valid an Access-Accept is send back to the Agent, which then forwards this to the access device, the user then gains access to the network resource. 3. If the user credentials are invalid an Access-Reject is returned and the CRYPTOCard Migration Agent forwards the RADIUS authentication request to its Secondary RADIUS Server entry (i.e.: CRYPTO- MAS). 4. If the users credentials are valid an Access-Accept is sent back and the user gains access to the network resource. An Access-Reject from CRYPTO-MAS will mean no access for the user. RADIUS Client configuration guides for a wide range of VPN, firewall and other network access devices or web based applications are available in the Support section of It is good practice to test an end-to-end RADIUS authentication using static passwords before installing the Agent. This simple step eliminates the possibility of RADIUS configuration errors, which will result in the Agent not receiving data from IAS/NPS. CRYPTOCard Migration Agent for CRYPTO-MAS 2

7 Installation Installation of the application requires three simple steps: 1. First of all you will need to download the Migration Agent. This will either have been sent to you by your Service Provider or you will need to download it from one of the links below CRYPTOCard RADIUS Proxy.exe for 32 bit servers CRYPTOCard RADIUS Proxy x64.exe for 64 bit servers 2. You will then need to configure the Microsoft IAS/NPS application and install the CRYPTOCard Agent: Installation and configuration instructions for use with Microsoft IAS begin with on page 4. Installation and configuration instructions for use with Microsoft NPS begin with on page You will need to configure your existing Authentication server to accept RADIUS requests from the CRYPTOCard Migration enabled IAS/NPS agent. Installing IAS and NPS On Windows 2003, the Microsoft Internet Authentication Service can be installed from Add/Remove Programs, Add/Remove Windows Components, Networking Services, Internet Authentication Service. On Windows 2008, the Microsoft Network Policy Server can be installed from Administrative Tools, Server Manager, Roles, Add Roles, Network Policy and Access Services.

21 Configuring your existing Authentication Server The final step of getting the CRYPTOCard Migration Agent working within your existing network is to configure your primary authentication server to communicate with the Agent. We recommend that you now configure your existing server and test the operation of the Agent prior to adding CRYPTO-MAS into your network. Your Service Provider will help you configure the existing server to communicate with the CRYPTOCard Migration Agent. The following information will be required to allow the agent to be set-up: Network devices must support the RADIUS Authentication Protocol. Please consult your third party documentation for compatibility. If a network device has been configured to perform a proprietary method of authentication, it must be reconfigured to RADIUS authentication (e.g.: RSA sometimes recommend the use of a nonstandard protocol). UDP Port 1812, 1813, 1645 and 1646 network traffic must be permitted between your network devices and the authentication servers. Various Third Party integration guides can be found in the Support Section of If an integration guide cannot be found for your device, please refer to the Third Party vendor documentation to enable RADIUS Authentication. Everything will now be set-up and tested so that any existing users are fully operational. Setting-up CRYPTO-MAS The next and final step is to add CRYPTO-MAS into the network. To do this we recommend you follow the very simple steps show in the How to Guide: Setting up your Account on CRYPTO-MAS. It might also be advisable to refer to the CRYPTO-MAS Administrators guide. This will explain how to get your account set-up, import the details of the users that you are migrating to CRYPTO-MAS and how to allocate tokens to those users.

22 Troubleshooting the CRYPTOCard Migration Agent for IAS / NPS Your CRYPTOCard Migration Agent should now be installed and working with both your existing authentication server and with CRYPTO-MAS. However, if for any reasons you are having problems, then the following may help you isolate any issues. Naturally, your CRYPTOCard Service Provider will be on hand to help. IAS / NPS logs All information between network devices and the Microsoft IAS RADIUS server log into the Event Viewer under System. In the Microsoft NPS RADIUS Server, the information appears in the Event Viewer under Custom Views, Server Roles, Network Policy and Access Services. Below is an example of a successful IAS authentication request User jsmith was granted access. Fully-Qualified-User-Name = <undetermined> NAS-IP-Address = <not present> NAS-Identifier = <not present> Client-Friendly-Name = Client-IP-Address = Calling-Station-Identifier = <not present> NAS-Port-Type = <not present> NAS-Port = <not present> Proxy-Policy-Name = Allow all users to authenticate to RADIUS Server Authentication-Provider = RADIUS Proxy Authentication-Server = auth.cryptocard.com Policy-Name = <undetermined> Authentication-Type = <undetermined> EAP-Type = <undetermined> CRYPTOCard Migration Agent for CRYPTO-MAS 18

23 Below is an example of a failed IAS authentication request User jsmith was denied access. Fully-Qualified-User-Name = <undetermined> NAS-IP-Address = <not present> NAS-Identifier = <not present> Called-Station-Identifier = <not present> Calling-Station-Identifier = <not present> Client-Friendly-Name = Client-IP-Address = NAS-Port-Type = <not present> NAS-Port = <not present> Proxy-Policy-Name = Allow all users to authenticate to RADIUS Server Authentication-Provider = RADIUS Proxy Authentication-Server = auth.cryptocard.com Policy-Name = <undetermined> Authentication-Type = <undetermined> EAP-Type = <undetermined> Reason-Code = 112 Reason = The remote RADIUS (Remote Authentication Dial-In User Service) server did not process the authentication request.
