In which cloud service model does the provider take responsibility for security up to the application level?

1. IaaS

2. PaaS

3. SaaS

4. DaaS

The correct answer is: SaaS

The correct answer is related to the cloud service model where the provider manages security up to the application level, which is characteristic of Software as a Service (SaaS). In this model, users access software applications hosted on the provider's infrastructure, and the provider handles everything from the security of the underlying infrastructure to the application itself. This means that the customer can focus on using the software without needing to manage or secure the underlying hardware or software. With SaaS, the provider ensures that aspects such as data encryption, application security, and compliance with regulations are taken care of, offering a higher level of oversight compared to other models. Users typically interact with the software via a web browser and do not have to worry about managing or securing the application environment. In contrast, during discussions about Infrastructure as a Service (IaaS) or Platform as a Service (PaaS), the responsibility for security is different. In IaaS, the customer manages the security of the operating systems and applications while the provider secures the hardware and virtualization layers. PaaS provides a platform where the provider secures the infrastructure and platform, but customers are generally responsible for the security of the applications they develop and deploy on that platform.
