Boffins build super firewall

Georg Carle, chair of the computing and Internet department at the University of Tübingen, in Germany, said that his Diadem Firewall uses hardware and software on the edge of a provider's network.

It detects a denial of service attack by using data filtering and intrusion prevention technologies. It then coordinates an automatic reaction based on preset security policies.

Diadem can cut off computers looking like they are violating policies, such as a machine that suddenly consumes a dramatically higher amount of bandwidth and have become zombies.

The technology will be useful to defend online gambling sites which usually get threats of an attack from online protection racketeers around the time of a sporting event.

Carle said that peered ISPs could share a common policy using Diadem, strengthening their effectiveness with a coordinated reaction to DDOS attacks.
