What is Business Process as a Service (BPaaS)

This real-world case study has been used to demonstrate the best practices on business process modelling and component based design for developing cloud services with Build Security In (BSI). BSI techniques, strategies, and processes presented in this article are general systems security principles and are applicable for both a cloud environment and traditional environment (non-cloud environment). The significant contribution of this research is to illustrate the application of the extended system security method known as SysSQUARE to elicit security requirements, identify security threats of data, as well as integrating build-in security techniques by modelling and simulating business processes upfront in the systems development life cycle.
