Project Overview
Asynchronous
Digital Subscriber Line (ADSL) Internet connection has grown rapidly
in NZ in recent years, especially for small office home office (SOHO)
customers, who want to utilize existing network infrastructures and
to take advantages of high-speed Internet connection and share it with
a small number of computers. Most of business oriented ADSL scheme charges
their customers by traffic usage, which is one of the attractive feature
to SOHO users comparing to leased lines, however it also makes them
suffers the most from distributed denial-of-service (DDoS) attacks,
which creates high volume of artificial traffic, disables services of
the network and mounting up Internet bills by unwanted data.
The
initial motivation of this project is to provide a solution on detecting
DDoS attacks by analysing statistics data from the border ADSL router
at the customer's promised site, and to quickly react when attack is
detected.
The ADSL
router we will be using to build our simulation environment is a Nokia
M1122, which is provided by Nokia New Zealand.
