Securing Trustworthy Three-Tier Grid Architecture with Spam Filtering

Grid is an emerging technology that aims at utilizing resources efficiently and effectively. The proposed robust three-tier architecture ensures trustworthy resource selection in a grid environment. This architecture is secured by using spam filtering mechanisms and by incorporating spamicity of a node in the computation of its trust value. For this purpose, a network of Anomaly Detection Agents (ADA) is set up at the Regional Resource Administrator (RRA) level which enables collaborative spam detection and filtering. The proposed solution detects and filters spam using layered filters consisting of statistical content-based and origin based spam filters.
