New firewall solution in offing to tackle DoS attacks

Researchers are developing a new firewall solution to prevent distributed denial-of-service (DDoS) attacks from crashing websites and networks.

Researchers are developing a new firewall solution to prevent distributed denial-of-service (DDoS) attacks from crashing websites and networks.

The Diadem Firewall is being developed by researchers at the University of Tübingen in Germany, and the project is being financed by the European Community.

A number of telcos are also involved in the project and commercial solutions from the prototype architecture produced may appear later this year.

The architecture sees both hardware and software located on the edge of networks rather than within.

Diadem uses data filtering and intrusion prevention technologies to detect malicious activity, then provides protection by co-ordinating an automatic reaction based on network policies set.

Current firewalls on the market don't incorporate policies into their capabilities.

Using Diadem, a network can cut off certain computers that appear to be violating policies, such as machines that are suddenly consuming dramatically higher amounts of bandwidth.

DDoS attacks involve hacked computers across the internet working in tandem to attack another machine, usually a web server or other central network platform.

Those involved in the Diadem Firewall project include France Telecom, IBM, Imperial College London, and Polish Telecom.
