Secure and flexible grid computing based intrusion detection system using mobile agents and cryptographic traces

Grid Computing is one of the new and innovative information technologies that attempt to make resources sharing global and more easier. Integrated in networked areas, the resources and services in grid are dynamic, heterogeneous and they belong to multiple spaced domains, which effectively enables a large scale collection, sharing and diffusion of data. However, grid computing stills a new paradigm that raises many security issues and conflicts in the computing infrastructures where it is integrated. In this paper, we propose an intrusion detection system (IDS) based on the autonomy, intelligence and independence of mobile agents to record the behaviors and actions on the grid resource nodes to detect malicious intruders. This is achieved through the use of cryptographic traces associated with chaining mechanism to elaborate hashed black statements of the executed agent code, which are then compared to depict intrusions. We have conducted experiments basing three metrics: network load, response time and detection ability to evaluate the effectiveness of our proposed IDS.
