DoS attackDenial 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.

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 SE551 WLAN dsl/cable offers WEP encryption and WPA for secure data transmission over wireless networks.

Ethernet

Ethernet is a network technology for local networks (LANs) defined by the IEEE as standard IEEE 802.3. Ethernet uses a base band cable with a transmission rate of 10 or 100 Mbps.
