Assessing the Effectiveness of Moving Target Defenses Using Security Models

摘要: Cyber crime is a developing concern, where criminals are targeting valuable assets and critical infrastructures within networked systems, causing severe socio-economic impact on enterprises individuals. Adopting moving target defense (MTD) helps thwart cyber attacks by continuously changing the attack surface. There numerous MTD techniques proposed in various domains (e.g., virtualized network, wireless sensor network), but there still lack of methods to assess compare effectiveness them. Security models, such as an graph (AG), provide formal method analyzing security, incorporating those security models has not been studied. In this paper, we incorporate into model, namely hierarchical representation model (HARM), addition, use importance measures (IMs) for deploying enhance scalability. Finally, scalability AG HARM when techniques, well changes performance our experiments.
