What Is VPN?
VPN stands for Virtual Private Network. A VPN is a virtual,
private network that uses the Internet as its physical base.
The VPN provides for secure data transmission.
All computers registered in the network are connected
with each other over the Internet so that they can ex-
change data. Data transmission takes place over IP, as in
the local network. In a pure transmission over IP the data
are not protected and thus exposed to unauthorized ac-
cess by third parties.
Security in a VPN is ensured by transmitting the data en-
crypted via what is known as tunnel. This excludes the
possibility of unauthorized access to the data. The tunnel
is the logical, virtual connection.
