Abstract: The trust running framework of ITIL platform can provide a good context environment for dynamic trust management, Most researches on dynamic access control focus on models of P2P or of grid platform, and few models arc used in ITIL platform. We proposed a framework to evaluate the trust of ITIL service based on the monitor performance in ITIL context environment, We calculated the trust value of ITIL service, and used IOWA calculator to help the evaluation and forecast of trust value of ITIL service in different time period. We also mined the frequent sequence in alarm log to improve the accuracy of forecast. Example analysis shows that our method has a good effect on fault analysis and resources optimization under ITIL platform.

Key words: ITIL Trust management, Dynamic access control, Operation monitor
