Attack Detection

If the firewall functions of the Gigaset SX763 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 SX763 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.

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

ì Select the security level for the firewall:

–The Medium default level offers high security and hardly limits functionality of

certain applications.

–The High level offers maximum security and may limit functionality for certain

applications.

–The Low level offers maximum functionality but may provide low security.

ì Click OK to apply the settings.

Setting up access control to the Internet

The Access Control function allows you to block access to various services for one or

more PCs. You can permit or block access to services at certain times.

ì In the Advanced Settings – Internet – Firewall menu, select Access Control.
