. The aim is not so much to steal data but to paralyse
the computer or network so severely that the network resources are no longer available.
A typical hacker attack involves making a remote computer announce that it is acting for
the paralysed computer, for example, and receive the data meant for you.

addressed on the
under the same Domain name regardless of the current
IP address.
Encryption
Encryption protects confidential information against unauthorised access. With an
encryption system, data packets can be sent securely over a network. The Gigaset SE551
WLAN dsl/cable offers
encryption and
for secure data transmission over wire-
less networks.
Ethernet
Ethernet is a network technology for local networks (
LANs
) defined by the
as stand-
ard IEEE 802.3. Ethernet uses a base band cable with a transmission rate of 10 or 100
.
