Two Factor Authentication for VPN

Allowing your remote employees access to internal network resources is a common expectation in today's mobile workforce. Numerous network security vendors such as Cisco, Juniper, Citrix and Checkpoint provide firewalls with built-in Virtual Private Network (VPN) capabilities that can allow authenticated users to access internal resources in a controlled manner. Two factor authentication for VPN access is a "must-have" for securing said external access to your networks.

VPNs are commonplace today - nearly all VPN solutions offer the ability to authenticate users directly against internal user directories such as Microsoft Active Directory or generic LDAP-based directories. This can make securing access munch more straight-forward to configure. Leveraging an existing user account also helps prevent password fatigue and reduces the overhead associated with an extra account and associated password.

Taking this one step further and requiring a VPN to perform two factor authentication is necessary - and is often a standard compliance requirement for most companies and organizations. PortalGuard can easily enable two factor authentication to VPNs using its built-in RADIUS server. PortalGuard requires users to enter their network username and password, as well as a one-time passcode from the token device of their choosing.
