New Technique for Denying Denial of Service Attacks
Denial of service attacks that flood a site with requests can be blunted by blocking users sending large number of requests. More advanced techniques send a small number of resource intensive requests. Researchers at IBM and Georgia Institute of Technology have created a way to deal with these attacks, too.
IEEE Computer reports in the May 2009 issue a new technique that focuses on the effects rather than on detection. Using an algorithm that assess the resource demands of requests, the anti-DDoS limits traffic from clients generating overly resource intense requests.
No word on when this will be commercially available.
