Microsoft, Amazon, and Google, among others, are leading the way in creating and offering advanced cloud computing systems at a low cost. Cloud computing’s largest security issue prevents people from embracing it. Cloud computing infrastructure security is crucial. Cloud infrastructure security research has addressed certain holes, but new issues keep arising. This systematic literature review (SLR) examines research on security, availability, integrity, confidentiality, network security, and cloud security concerns. This SLR assessed prominent digital libraries’ 2017–2022 research studies. After careful screening, we chose 115 publications to address the study questions. Secure communication may be achieved by encrypting cloud data. This research also examined some key issues that make cloud security engineering difficult.
Kanakasabapathi et al. (2026) studied this question.
