A New Flexible Multi-Agent Approach to Intrusion Detection for Grid

Grid is a new technology which implements flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources. Unlike in conventional network systems, the services and resources in grid are heterogeneous and dynamic, they also belong to different domains. So the intrusion detection system (IDS) for grid should be a system which could rapidly and dynamically integrate the related node detection resources of a grid computing application according to the dynamic detection demand and ensure the security of grid computing. Conventional network IDS lack the necessary flexibility needed by grid environment and could not dynamically adjust their structure to the dynamic grid computing applications. This paper provides a new flexible multi-agent approach to intrusion detection for grid (MAIDG). MAIDG not only takes advantage of the flexibility and autonomy of agent technology, but also makes good use of the Globus Toolkit4.0 (GT4)'s data management components which provide the virtual interfaces for all the (heterogeneous or homogeneous) detection resources and realize the publication, location, and high performance transfer of detection data. In a word, this paper provides a new ideal and way to realize the intrusion detection system for grid
