Abstract

The Grid is an emerging resource intensive environment that aims at utilizing resources efficiently and effectively. Distributed Denial-of-Service (DDoS) attacks on the Grid can have a devastating effect since there are several resource constraints in a Grid environment. A DDoS can cause large-scale damage to resources and availability of the resources to genuine Grid users. This paper proposes a five-fold DDoS Defense Mechanism using an Information Divergence scheme that detects the attacker and discards the adversary's packets for a fixed amount of time in an organized manner. The trust value is adjusted based on the attack intensity to ensure a trustworthy system. The mitigation is carried out by limiting the bandwidth of the attacking IP instead of completely blocking the attackers IPs. With this, the job success rate is more by the proposed approach compared to completely blocking the attackers IP approach.
