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 meant for you.
DSL
Digital Subscriber Line
DSL is a data transmission 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
Provider. It requires a DSL modem.
Dynamic IP address
A dynamic IP address is assigned to a network component automatically by the DHCP.
This means that the IP address of a network component can change with every login or
at certain intervals.

DynDNS
Dynamic DNS
The assignment of Domain names and IP addresses is handled by the Domain Name
Service (DNS). For Dynamic IP addresses this service is now enhanced with so-called
Dynamic DNS (DynDNS). It 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
SX541 WLAN dsl offers WEP encryption and WPA for secure data transmission over wire-
less networks.
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 transmission rate of 10 or 100
Mbps.
Exposed Host
Exposed Host refers to a PC outside the firewall.
