An Enhanced Multidimensional Security Framework for Securing PaaS-Based E-Commerce Cloud Environments

Abstract

The fast movement to cloud computing has made Platform-as-a-Service (PaaS) one of the most
significant enablers of the scalable and agile E-commerce applications. Nevertheless, PaaS environments
pose serious security issues because of multi-tenancy, dynamic workloads, shared service elements, and
high-performance demands. Traditional security strategies tend to respond to isolated threats and do not
weigh the security performance with the operational performance. The given paper offers to introduce the
Enhanced Multidimensional Security Framework (PaaS-MSF) that should be used in order to protect the
PaaS-based E-commerce cloud environment and maintain the sustainability of its performance.
The suggested framework will incorporate several security aspects such as identity and access control,
context-wary risk determination, intrusion detection and response, tenant isolation, compliance
monitoring, and performance-conscious enforcement in one architecture. A multi-phase developmental
evaluation approach is embraced and integrates organizational survey analysis, stochastic security
simulation on StochSS, cloud performance modelling on CloudSim Automation and statistical validation
on SPSS. This will allow experimental and reproducible testing under baseline and more secure settings.
As it is evidenced by experimental outcomes, the suggested framework is much better at detecting
intrusions, preventing them, and containing threats than traditional PaaS security frameworks. Notably,
these security improvements are made with less effect on critical performance indicators like response
time, throughput and resource usage. The results indicate that context sensitive and adaptive security
enforcement are capable of addressing threats with respect to E-commerce without bringing about
unacceptable performance burden.
Altogether, this research brings a validated, performance-conscious, and standards-oriented security
framework that will further theoretical and practical knowledge on the topic of PaaS security. The
suggested solution is an informative resource to cloud service providers, E-commerce platforms, and
security practitioners who might need to improve the security resilience of their environment in the
current cloud setting.
