If the web application is not available what is the impact to the business, mission?

In April 2009, government and financial sites in the U.S. and South Korea were attacked by DDOS and were brought offline for days. This incident followed the Estonian DDOS attacks in 2007 and Georgian DDOS attacks in 2008. However, the attacks used in these incidents were primarily Layer 4 (TCP) attacks which are already addressed by anti-DDOS solutions.

A NEW and very lethal form of Layer 7 attack technique, which uses slow HTTP POST connections, was discovered by Onn Chee and his team in Singapore in 2009.

As it is a Layer 7 attack, existing Layer 4 protection systems may not be able to defend against such an attack. In addition, unlike the HTTP GET DDOS attack technique, both Apache and IIS web servers are vulnerable to HTTP POST DDOS attacks. Onn Chee and Tom Brennan will walk through the details of how this lethal HTTP POST DDOS technique works, other interesting findings in the protocol and the challenges in defending critical infrastructure against such attacks.

They will also demonstrate how an "agentless" DDOS botnet can be created via malicious online games and how a victim website can be brought down in matter of minutes using the HTTP POST DDOS attack.

A Q&A session will be held at the end to solicit ideas on how best to defend against this new and lethal DDOS attack technique.
