4 1 Overview The Purpose of this document is to demonstrate how to secure your Juniper SSL VPN login with he DIGIPASS KEY 200. This device let s you add a certificate and be able to logon with the right user credentials. 2 Problem Description Today s business is built around information applications. To ensure business workflow, productivity and enhancing client relationships, internal network resources are increasingly been made accessible from anywhere. The weakest link in any security infrastructure is the use of static passwords. These passwords are easily stolen, guessed, reused or shared. There is a need for strong user authentication, based on 2-factors: something you have and something you know. 3 Solution By creating an extra profile in your organization, the Enrollment Agent, It will be possible to rollout certificates on the DIGIPASS KEY 200 for every user. With the DIGIPASS KEY 200 it is possible to login to Juniper SSL VPN. This way you create a safe and easy manageable environment for you and all your users. Figure 1: DIGIPASS KEY 200 There is also the possibility to use a simple smart Card, allowing as well the rollout of certificates on the Digipass smart Card. Digipass 905 is VASCO s smart card reader. The procedure for configuring the certificates on the card, is identical to the KEY 200 configuration.

5 4 Technical Concept 4.1 General overview The basic working of the Juniper SA is based on authentication to an existing media (Certificate Authentication, LDAP, RADIUS, local authentication ). To use the IDENTIKEY with Juniper SA, the external authentication settings need to be changed or added manually. After configuring the Juniper SA SSL VPN and insert the user certificate to the DIGIPASS KEY 200 in the right way, you eliminate the weakest link in any security infrastructure the use of static passwords that are easily stolen guessed, reused or shared. The DIGIPASS KEY 200 functionality provides document signing; strong authentication against PKI enables software systems (operating systems, virtual private networks, applications); as well as , file and disk encryption. 4.2 Procedure To make the DIGIPASS KEY 200 work with the login in Juniper SSL VPN, there are a few steps that need to be taken. First of all you have to setup a Certificate Authority. This will be the issuer for the certificate used on the DIGIPASSKEY 200. Next we will make sure all the correct user rights are set. We will make a new group that will be responsible for issuing certificates. This will become a powerful group as they can generate certificates for all domain users, including administrators. Add as last we have to enroll the users to the DIGIPASS KEY 200 and login to Juniper SSL VPN. 4.3 Prerequisites The initial prerequisites for setting up DIGIPASS Juniper SSL VPN are: Active Directory installed on a Windows 2000 or 2003 domain server A Microsoft Certificate Authority (CA) configured with the Enterprise policy module. This may be a root or subordinate CA.
