Abstract

Federated cloud systems increase the reliability and reduce the cost of computational support to an organization. However, the resulting combination of secure private clouds and less secure public clouds impacts on the overall security of the system as applications need to be located within di erent clouds. In this paper, the entities of a federated cloud system as well as the clouds are assigned security levels of a given security lattice. Then a dynamic flow sensitive security model for a federated cloud system is introduced within which the Bell-LaPadula rules and cloud security rule can be captured. The rest of the paper demonstrates how Petri nets and the associated veri cationtechniques could be used to analyze the security of information flow in federated cloud systems.
