used to set
up a secure subnetwork over an
open, unprotected
network (Internet, radio

protected against monitoring and access by
external users. This is done by “tunneling”
the data traffic over a VPN server, where
the connections must be authenticated
during setup, and by simultaneously en-
crypting the data.
WLAN
