BEIJING, June 27, 2013 /PRNewswire/ -- NSFOCUS. Distributed denial of service (DDoS) and Web attacks significantly impact Data Center and Web Hosting businesses. Both attacks are complicated, but in different ways. It raises the question: is it possible for data centers to simultaneously mitigate DDoS attacks and Web attacks both accurately and cost-effectively? Congyu Li, product manager for NSFOCUS, answered this question in a speech at the RSA Asia Pacific conference 2013. A new solution for stopping DDoS attacks and Web attacks was introduced, which is a collaborative solution between two well-known protection systems.
"It has been the consensus in the Data Center industry that the best spot to stop a DDoS attack is in the backbone of the network because the size of the attack traffic can be quite large. Data centers usually provide mitigation of DDoS attacks as a part of their infrastructure service. On the other hand, Web attacks are large in volume, but their payload goes up to the application level," said CongYu Li. "In the current market, professional Anti-DDoS Systems (ADS) can mitigate volumetric DDoS attacks. Professional Web Application Firewalls (WAF) can mitigate Web attacks and small volumes of DDoS attacks. However, having ADS and WAF operating separately to defend against both DDoS attacks and Web attacks is not an ideal solution for data centers as Web Hosting customer cannot be transferred from DDoS attack mitigation service to Web attack mitigation service smoothly and efficiently when the attack methodology and tactics change."
The new solution starts from Anti-DDoS module in a Web Application Firewall. The WAF can fend off small-scale DDoS attacks. If the DDoS attack is larger than the WAF can handle, it will send a notice to the ADS in the backbone of the network to take the attack traffic. The ADS will then use the IP information from the WAF to take a series of actions to mitigate the large-scale attacks of higher performance and capacity.
The collaboration of the two systems is automatic and well-functioned. For data centers, it not only provides proactive mitigation protection, but also reduces cost in both technical resources and administration.
