Attack Detection

If the firewall functions of the Gigaset SX762 WLAN dsl are activated, the device moni-
tors and limits access to incoming data traffic via the DSL connection with a function
called "Stateful Packet Inspection" (SPI). This allows the Gigaset SX762 WLAN dsl to
detect 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 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 and
arrange to be notified by e-mail about any attempted hacker attacks.

In the Advanced Settings – Internet – Firewall menu, select Attack Detection.
