![]() ![]() The VPN builds an encrypted "tunnel" through a public/private network which provides the necessary confidentiality (this prevents snooping), sender authentication (this prevents identity spoofing), and data integrity for secure access to private resources.Ī VPN client allows you to "tunnel" all of your traffic to UCSB over an encrypted, authenticated link that terminates on campus at our VPN server. Typically a VPN is used when some part of the network path crosses a public network such as the Internet or, in the case of wireless, "airspace." A VPN may also be used to provide additional security on private networks. A VPN is an alternative to a truly private network, in which someone completely owns the infrastructure (i.e., wires) between locations and no one else can use it.
