摘要: This work examines the use of model checking techniques to verify system-level security properties a collection interacting virtual machines. Specifically, we examine how local access control policies implemented in individual machines and hypervisor can be shown satisfy global constraints. The SAL checker is used stateful domains with protected resources MAC attempting needed from other domains. described along verification conditions. need state-space explosion motivated for writing theorems limiting explored. Finally, analysis results are examined complexity.
