The reasoning behind the acceptance of penetration testing in certain cloud models relates to the level of control and responsibility assumed by the user versus the service provider. In the context of cloud service models, Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) generally provide a higher level of access and control compared to Software as a Service (SaaS).

PaaS tends to allow developers control over application deployment and management, enabling them to conduct security assessments, such as penetration testing, to identify vulnerabilities in their applications before they are fully deployed. This responsibility aligns with security best practices, where application developers need to ensure their software's security posture proactively.

While in a SaaS model, the service provider typically manages the entire stack, including infrastructure, application, and data security. Users of SaaS applications often lack the control needed to perform penetration testing legally and effectively because this is typically not allowed due to the constraints of using shared environments and the provider's management of the service.

When evaluating the context of the different models, IaaS indeed offers penetration testing permissions, but the key focus of this question is on the PaaS model, which allows users to actively engage in testing and securing their applications within the environment. As
