Intrusion Detection for Computational Grids

Current intrusion detection technology is limited in providing protection against the intrusions that may violate the security of computational grids. We present the problem of grid intrusion detection, describe the requirements of a system to detect them, propose a grid intrusion detection method, and show how it overcomes the limitations by integrating the detection of the typical host computer and network attacks with the detection of grid-specific attacks and user behavior anomalies. This integration is evaluated with a case study that makes use of simulations and a prototype implementation.
