Executive Summary

Over the past two decades, the Internet has become of critical importance for social, business, and government activities. Corporations depend on Internet availability to facilitate sales and the transfer of data to make timely decisions. SCADA networks often use the Internet to enable coordination between physical systems. Unfortunately, malicious parties have been able to flood end hosts with traffic to interrupt communication. In these Denial-of-Service (DoS) attacks, the network link to the server is congested with illegitimate traffic so that legitimate traffic experiences high loss, preventing communication altogether.
