NTT Com Launches Traffic Analysis System for DDoS Attacks

NTT Communications (NTT Com) announced the launch of a network-type traffic-analysis system that corporate customers can use to protect servers or routers from distributed denial-of-service (DDoS) attacks. The system initially is being offered to customers using NTT Com's Tier 1* Global IP Network in Japan.

DDoS attacks are malicious attempts to render network servers unavailable to legitimate users. Distributed attacks, as compared with single attacks, use denial-of-service methods such as commanding multiple PCs or servers to send mass amounts of data that overload the targeted server and thereby deny it from providing its intended services.

The new system is designed for enterprises using NTT Com's transit and collocation transit services for IPv4 traffic. The most advanced version of the system combines traffic-analysis software and mitigation devices to detect and protect against DDoS attacks. Remote installation is achieved via NTT Com’s global Tier 1 backbone, resulting in lower costs and simpler operation of the system on the customer’s side.

The system sends an alert to the customer if network traffic suddenly exceeds a preset threshold. A dedicated screen connected to the system enables the customer to monitor the situation in real time during a suspected DDoS attack, as well as analyze traffic under normal conditions.

The advanced version, which provides traffic analysis and both DDoS attack detection and mitigation protection, costs from 682,500 yen (tax included) for installation and 420,000 yen (tax included) monthly.

NTT Com is considering offering upgraded Mitigation devices and software for more enhanced DDoS protection, as well as launching an international version of the system.

*A global broadband IP backbone that uses peering relationships only to acquire and forward traffic, while not depending on any other ISP as a last-resort destination for traffic.
