Recently a number of highly publicised incidents of Distributed Denial of Service (DDoS) attacks have made people aware of the importance of providing available securely the grids’ data and services to users. This paper introduces the vulnerability of grids to DDoS attacks, and proposes a distributed defense system that has a mixture deployment of sub-systems to protect grids from DDoS attacks. According to the simulation experiments, this system is effective to defend grids against attacks. It can avoid overall network congestion and provide more resources to legitimate grid users.
