IntelliGuard announces Australian release of revolutionary new DDoS defense

20 May 2008 - IntelliGuard today announced the Australian release of its DPS security appliances that defend against the largest and most sophisticated Distributed Denial of Service (DDoS) attacks. The Australian launch comes on the back of the appointment of Asian resellers, and deployments with a number of the largest Chinese and Korean IDCs, Internet gaming companies, and video sharing websites.

To enable Service Providers to protect their own networks and those of their customers, IntelliGuard’s DPS employs a unique “Learn-Rank-Protect” strategy that profiles and ranks by legitimacy every client that interacts with a protected network, and only discards the least legitimate traffic during DDoS attacks or flash crowds when traffic rates need to be reduced.

As IntelliGuard Chief Scientist, Dr Tao Peng explains, “Attackers can circumvent traditional anomaly detection and signature-based devices by sending traffic that is outwardly indistinguishable from legitimate traffic, and adjusting their attacks to get around filtering rules. Effective decisions about which traffic to pass need to be based on information that attackers don’t have and cannot easily guess. The only data that fits this description is detailed historical knowledge of a particular network’s regular clients. We have developed a way to learn enough about a network’s legitimate users to be able to identify and prioritize their traffic in the midst of all types of traffic floods whether from attackers or non-malign causes.”

To protect each part of a network, IntelliGuard’s DPS incorporates a novel Hierarchical Multi-Level Traffic Management system that configures traffic limits and guarantees to manage traffic rates for each part of a network. This enables an IntelliGuard DPS deployed at the network edge to independently protect every component of a complex network, from large links all the way down to individual services running on a single machine.

According to IntelliGuard Chief Technical Officer Dr David Powell, “Hierarchical Multi-level traffic management is the only sure way to protect vulnerable low bandwidth services. Attackers can target anything from upstream routers, a business’ downlink, firewall, IPS, web server process, network card, operating system and TCP/IP stack. Each component is vulnerable and handles different traffic rates, so each therefore needs to be independently protected. Only IntelliGuard can do this, making our product unique in the world”.
