Figure 55: Security Screen
If enabled, DoS (Denial of Service) attacks will be detected and
blocked. The default is enabled. It is strongly recommended that
this setting be left enabled.
Note:

A DoS attack does not attempt to steal data or damage your
PCs, but overloads your Internet connection so you can not
use it - the service is unavailable.

This device uses "Stateful Inspection" technology. This
system can detect situations where individual TCP/IP pack-
ets are valid, but collectively they become a DoS attack.
If you wish to adjust the settings used by the DoS firewall, click
this button to open a sub-window.
The ICMP protocol is used by the "ping" and "traceroute" pro-
grams, and by network monitoring and diagnostic programs.

If checked, the Wireless Router will respond to ICMP pack-
ets received from the Internet.

If not checked, ICMP packets from the Internet will be ig-
nored. Disabling this option provides a slight increase in
security.
