Attack Detection - Siemens Gigaset SX761 dsl Manual

Attack Detection

If the firewall functions of the Gigaset SX761 dsl are activated, the device monitors and
limits access to incoming data traffic via the DSL connection with a function called
"Stateful Packet Inspection" (SPI). This allows the Gigaset SX761 dsl to detect and pre-
vent 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 as to paralyse the computer or network to such an extent that the
network resources are no longer available. A typical hacker attack involves, for example,
a remote computer acting in place of the paralysed device and receiving the data
intended for the device.
You can use the Attack Detection function to change the standard firewall settings.
