Towards Models for Availability and Security Evaluation of Cloud Computing with Moving Target Defense [article]

Matheus Torquato, Marco Vieira
2019 arXiv   pre-print
To overcome this challenge, we intend to propose a set of models to evaluate the availability and security of MTD in cloud computing environments.  ...  MTD makes use of dynamic reconfiguration in virtualized environments to "confuse" attackers or to nullify their knowledge about the system state.  ...  In the cloud computing context, MTD techniques can be used to thwart or reduce the impact of security attacks as co-residency attacks [8] and Distributed Denial of Service attacks [9] .  ...

Modeling and Mitigating Security Threats in Network Functions Virtualization (NFV) [chapter]

Nawaf Alhebaishi, Lingyu Wang, Sushil Jajodia
2020 Lecture Notes in Computer Science  
In this paper, we take the first step toward modeling and mitigating security threats unique to NFV. Specifically, we model both cross-layer and co-residency attacks on the NFV stack.  ...  As NFV relies on virtualization, and as an NFV stack typically involves several levels of abstraction and multiple co-resident tenants, this new technology also unavoidably leads to new security threats  ...  In contrast to clouds, NFV may have an increased attack surface in terms of co-residency attacks.  ...

Kang Chen, Qingni Shen, Cong Li, Yang Luo, Yahui Yang, Zhonghai Wu
2016 Proceedings of the 2nd International Conference on Information Systems Security and Privacy  
But security has been a major barrier for its adoption to enterprise, as being placed with other tenants on the same physical machine (i.e. co-residency or co-location) poses a particular risk.  ...  Former research has shown how side channels in shared hardware may enable attackers to exfiltrate sensitive data across virtual machines (VMs).  ...  It is mentioned above that coresidency attacks in public clouds involve two steps: a launch strategy and co-residency detection.  ...
