Virtual Private Network. Vpns help
solve an expensive problem for companies that want to set up their own
private data networks. Instead of relying on costly leased lines to
build their infrastructure, they use special encryption protocols in
conjunction with tunnelling protocols such as pptp to
broadcast data across public communications channels such as the internet.
Vpns are now widely used by companies with lost of remote works, who
need to give employees secure access to data on corporate lans across
normal dial-up or broadband connections. |
