Configuring the Advanced Settings

Attack detection

If the firewall functions of your Gigaset SE551 WLAN dsl/cable 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 SE551 WLAN dsl/ cable 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 connec- tions. 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.

You can use the Attack Detection function to change the standard firewall settings and arrange to be notified by email about any attempted hacker attacks.

ìIn the Advanced Settings – Internet – Firewall menu, select Attack Detection.ìSelect the security level for the firewall.

The default setting is Medium, which combines a high degree of security with little effect on functionality.

–The level High offers you maximum security with possibly limited functionality for special applications.

–The level Low offers you maximum functionality with possibly reduced security.
