PRESS RELEASE

NEW YORK--(EON: Enhanced Online News)--NTT America, a wholly owned U.S. subsidiary of NTT Communications Corporation (NTT Com) and a global IP network services provider, today announced a white paper focusing on the growing number and type of network attacks, the impact of low traffic or "silent" threats, and how large and small networks can help mitigate this growing problem. The paper will be presented by Darren Grabowski of the NTT America Security & Abuse Team at the IEEE Globecom 2008 conference in New Orleans on December 1. The white paper will be available beginning December 3 on NTT America's web site at http://us.ntt.net/products/case_studies/.

The company is presenting as part of a broader session chaired by Dr. Kazuhiko Ohkubo of NTT, with panelists discussing comprehensive approaches related to security improvement in advanced telecommunications networks, new service creation based on the ring of trust, and ROI management for security measures. The session will take place on Monday, December 1 from 1:50 p.m. to 3:30 p.m. EST.

The white paper entitled, The Global Pandemic - The Silent Threat, covers how millions of computers on the Internet are compromised and discusses the ability of a single malicious botnet to harness these machines to take down key Internet infrastructure and create financial havoc. The paper outlines measures networks can take to mitigate these attacks using many tools already available to help prevent attacks and minimize costs.

"Spam, malware, phishing and DoS are all growing problems that are not going to go away," said Darren Grabowski, Manager of the NTT America Security & Abuse Team. "Large and small networks need to work together to deploy monitoring devices and report their findings to mitigate this growing problem. Companies often have the tools they need on their network already and with just a small investment in time and effort they can use them to protect themselves in a more proactive fashion with little or no increase in cost."

The NTT America Security & Abuse Team is tasked with responding to security (port scans, malware DoS, etc.) and abuse (spam) issues across the entire NTT Com Global IP Network. They also continuously monitor the network using a variety of tools including those that watch for trends of low bandwidth consumption, compared to legitimate traffic, which can hide the "silent threat."
