Which security control is a shared responsibility in the software as a service (SaaS) model?

In the Software as a Service (SaaS) model, the security of applications is a shared responsibility between the service provider and the customer. The provider is responsible for securing the underlying infrastructure, such as the servers and networks that host the application, as well as for maintaining the application's security from a technical standpoint. This includes regular updates, patches, and the implementation of security protocols.

However, customers also have a role to play in managing their own security within the application. This might include setting strong user passwords, managing access controls, and ensuring that user data is handled correctly and securely. The shared responsibility model in SaaS means that while the service provider manages and secures the application, customers must also understand their role in protecting their data and how they use the application.

Security controls related to data and applications are particularly important in the SaaS model because of the way services are delivered and accessed over the internet. Users rely on the provider to maintain a secure application, but they must also ensure that their use of the application aligns with best security practices to mitigate risks associated with data breaches and unauthorized access.
