What does the AWS shared responsibility model define?

The AWS shared responsibility model clearly outlines the division of security responsibilities between AWS as the cloud service provider and the user of the AWS services. In this model, AWS is responsible for the security of the cloud infrastructure, which includes securing the hardware, software, networking, and facilities that run AWS services. This means ensuring that the physical aspects of the cloud are protected against unauthorized access or physical attacks.

On the other hand, users are responsible for securing their own data and applications running on the AWS infrastructure. This includes configuring security settings, managing user access and permissions, and ensuring data protection measures are in place, such as encryption and secure access protocols.

Understanding the shared responsibility model is crucial for any AWS user, as it delineates what security measures must be taken by the user to protect their workloads and data while leveraging AWS's security capabilities for the underlying services. This knowledge helps users implement the necessary security controls and practices required to safeguard their information in the cloud effectively.

The other choices do not accurately capture the primary focus of the shared responsibility model. While AWS support teams provide help, that is separate from the shared responsibility framework. Similarly, cost management strategies and backup protocols pertain to operational aspects of using AWS rather than the delineation of security responsibilities.
