Attack Detection

If the firewall functions of your Gigaset SX541 WLAN dsl are activated, the device monitors and limits the access of incoming traffic via the DSL connection with a function called Stateful Packet Inspection (SPI). This allows the Gigaset SX541 WLAN dsl to identify and prevent certain types of attack from the Internet, such as Denial-of-Service (DoS). DoS attacks are aimed at devices and networks with Internet connections. The aim is not so much to steal data but to paralyse the computer or network to such an extent 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 device, for example, and receive the data meant for it.
