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 func-
tion 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.
