Abstract

As companies increasingly use virtualized data centers and cloud services, new weaknesses have opened up in enterprise infrastructure. At the same time, denial-of-service attacks (DoS) are moving from brute-force floods of data to more skillful attacks on application infrastructure. The combination is increasingly threatening for the companies that are placing critical business data outside their facilities, leaving their business reliant on continuing communications. In addition, with multi-tenant services becoming more common, attacks aimed at one company could dramatically impact the services of an unrelated, but co-located, firm. This paper deals with the use of Adaptive WRed, a congestion control queuing behavior to put an end to the DDoS attacks on the cloud environment.
