摘要: Moving Target Defense (MTD) is a proactive security solution, which can be utilized by cloud computing in order to thwart cyber attacks. Many MTD techniques have been proposed, but there still lack of systematic evaluation methods for assessing the effectiveness proposed techniques, especially when multiple are used combinations. In this paper, we aim address aforementioned issue proposing an approach modeling and analysis techniques. We consider four metrics: system risk, attack cost, return on attack, availability quantify before after deploying Moreover, propose Diversity technique deploy OS diversification with various variants VMs also combined Shuffle, Diversity, Redundancy improve cloud. analyze metrics show them. utilize importance measures based network centrality into phase scalability evaluation.
