3.5.3 DoS (Denial-of-Service)
Denial of Service (DoS) is a common attack measure, by transmitting a great amount of data or
request to your Internet IP address and server, the Internet connection will become very slow,
and server may stop responding because it is not capable to handle too much traffics.

stop the DoS attack for you.
