Trust-based security-level evaluation method for dynamic service orientedenvironments

摘要

A method of decision-making in security-level estimation process of service-based applications in futurernInternet architecture is proposed. We demonstrate how distributed services can be composed to form an applicationrnrun within the next-generation network infrastructure and their security level may be assessed. Ourrnapproach is illustrated by the experiments carried on exemplary application (virtual laboratory online lab, usingrnfuture Internet IPv6 QoS architecture), in which our method was evaluated against two types of attacksrnobserved with the use of traffic anomaly detection methods.
