SSL VPN
A SSL VPN (Secure Sockets Layer virtual private network) allows users to
establish a secure, remote-access VPN tunnel to this device by using a web
browser. Users do not need a software or hardware client preinstalled on their
computers. SSL VPN provides secure, easy access to a broad range of web
resources and web-enabled applications from almost any computer on the
Internet. They include:
•Internal websites
•Web-enabled applications
•NT/Active Directory file shares (i.e. My Network Place)
•MS Outlook Web Access
•Application Access (port forwarding access to other TCP-based
applications)
SSL VPN uses the Secure Sockets Layer protocol and its successor, Transport
Layer Security, to provide a secure connection between remote users and
specific, supported internal resources configured at a central site. This device
recognizes connections that must be proxied, and the SSL VPN web portal
interacts with the authentication subsystem to authenticate users.
Access to resources by users of SSL VPN sessions is provided on a group basis.
Users such as business partners can be put into a group that has no direct access
to resources
on the internal network. Or, for users that require access to all resources in the
internal network, this device supports Virtual Passage, which allows authorized
users to obtain an IP address from this device through a SSL VPN tunnel and are
then a part of the internal network.
