DoS attack
Denial of Service
A DoS attack is a particular form of hacker attack directed at computers and networks
with a connection to the
Internet
. 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 intended for you.
DSL
Digital Subscriber Line
DSL is a data transfer technique in which a connection to the
Internet
can be run at 1.5
Mbps
over normal telephone lines. A DSL connection is provided by an
Internet service
provider
. It requires a DSL modem.
Dynamic IP address
A dynamic
IP address
is assigned to a network component automatically by
DHCP
. This
means that the IP address of a network component can change with every login or at
certain intervals.

Static IP address
DynDNS
Dynamic DNS
The assignment of
Domain names
and
IP addresses
is handled by the Domain Name
Service (
DNS
). This service is now enhanced with so-called Dynamic DNS (DynDNS) for
Dynamic IP addresses
. This enables the use of a network component with a dynamic IP
address as a
Server
on the Internet. DynDNS ensures that a service can always be
addressed on the
Internet
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 SE555
WLAN dsl offers
WEP
encryption and
WPA
for secure data transfer over wireless net-
works.
Ethernet
Ethernet is a network technology for local networks (
LANs
) defined by the
IEEE
as stand-
ard IEEE 802.3. Ethernet uses a base-band cable with a transfer rate of 10 or 100
Mbps
.
Firewall
Firewalls are used by network operators as protection against unauthorised external
access. This involves a whole bundle of hardware and software actions and technologies
that monitor and control the data flow between the private network to be protected and
an unprotected network such as the
Internet
.
