A Survey of Security in Cloud, Edge, and Fog Computing

Area of Science:

• Computer Science
• Information Security
• Network Computing

Background:

• The convergence of Cloud, Edge, and Fog computing creates a complex ecosystem with diverse architectures.
• This heterogeneity introduces significant security and privacy challenges.
• Existing research lacks a consolidated view of these challenges across paradigms.

Purpose of the Study:

• To systematically review and identify similarities and differences in security and privacy threats across Cloud, Edge, and Fog computing.
• To analyze common attacks and existing countermeasures within these computing paradigms.
• To pinpoint the impact of ecosystem heterogeneity on security and privacy mechanism deployment.

Main Methods:

• Systematic literature review methodology.
• Analysis of research papers focusing on information security and privacy in distributed computing.
• Comparative analysis of security threats and countermeasures across Cloud, Edge, and Fog computing.

Main Results:

• Identified essential security and privacy threats inherent to the heterogeneous computing ecosystem.
• Outlined key similarities and differences in security postures between Cloud, Edge, and Fog computing.
• Highlighted that system heterogeneity significantly hinders the effective deployment of security and privacy solutions.

Conclusions:

• The diverse nature of Cloud, Edge, and Fog computing presents substantial obstacles for robust security and privacy.
• Effective mitigation strategies require tailored deployment techniques to address specific shortcomings.
• Further research is needed to develop unified and adaptable security frameworks for these evolving computing environments.
