CLOUD COMPUTING SECURITY MODELS GUARANTEE: A SYSTEMATIC REVIEW

Security in mobile and cloud computing is critical due to the high volume of sensitive data, remote access, and evolving cyber threats. Both domains require layered defenses, proactive monitoring, and regulatory compliance to ensure confidentiality, integrity, and availability. Cloud Computing Security: Cloud security involves protecting cloud infrastructure, applications, and data from threats like data breaches, DDoS attacks, insider threats, and misconfigurations. It uses the internet network for data distribution and operates on a shared responsibility model—the cloud provider secures the infrastructure, while customers secure their data, applications, and configurations. The back-end of the cloud network gives users access to resources such as Infrastructure as a Service (IaaS), Software as a Service (SaaS), Desktop as a Service (DaaS), Platform as a Service (PaaS), etc. It uses several security models, and yet it encounters serious data breaches, particularly in public cloud computing. Owing to this, the authors researched various cloud computing security models to ascertain the best model for the cloud computing system. The Systematic literature review methodology adopted the Kitchenham method. The literature was searched across leading academic databases. To ascertain the best quality, various cloud computing security models were analysed using a thematic analysis approach for identification, analysis, and reporting patterns for collated data. However, the finding shows that the RSA security model is not the only asymmetric security model. Meanwhile, it is the most concise with a simple arithmetic method, and the easiest to code. So, the review indicated RSA as the best cloud computing security model, but it needed an upgrade to accommodate primary key regularly updating to avoid data redundancy.
