Which does the cloud customer maintain responsibility for in the SaaS model?

In the Software as a Service (SaaS) model, the cloud customer primarily maintains responsibility for their access and administration of the software application. This includes managing user access rights, setting up user accounts, and ensuring that users have the appropriate permissions to carry out their functions within the application.

SaaS providers typically handle the infrastructure, including the physical servers and network security, which is why the customer does not maintain responsibility for those aspects. While data encryption can be implemented by customers within the application, the overall responsibility for infrastructure security and physical server maintenance lies with the SaaS vendor, as they provide the underlying platform and environment where the application runs. Therefore, focusing on access and administration is crucial for customers to safeguard their data and ensure that only authorized personnel can interact with the SaaS application.
