NTT invents device to stop Denial of Service (DOS) attacks

JAPANESE NEWSPAPER Nihon Keizai Shimbon reports today that Nippon Telegraph and Telephone (NTT) has invented technology which will prevent distributed denial of service attacks.

It works, the paper said, by using bridge devices which can detect the source of attacks and prevent access to these while allowing other data to continue to flow across the network.

The bridge devices query the data streaming in when an attack occurs, and sniff for similar suspicious data further up the the internet, eventually identifying the source of the attack.

When that information is received, the bridge software then blocks other data coming from the same source, the report said.

NTT is already testing the method, it appears. µ
