The "Shared Responsibility Model" is a concept used in cloud computing that defines the responsibilities of both the cloud provider and the customer in terms of security and management of the infrastructure and data.
According to this model, the cloud provider (in this case, AWS) is responsible for the security and maintenance of the underlying infrastructure, such as the physical data centers, network infrastructure, and server hardware.
On the other hand, the customer is responsible for managing and securing the applications, data, and operating systems that run on top of the cloud infrastructure. This includes setting up and maintaining security controls such as firewalls, encryption, and access controls, as well as configuring and monitoring the network and application infrastructure.
Given the options provided, the correct answer for the customer's responsibility under the Shared Responsibility Model is B. Client-side data encryption. This refers to the encryption of data by the customer before it is sent to AWS. While AWS provides server-side encryption for data at rest, it is the customer's responsibility to ensure that sensitive data is protected while in transit or while being processed by their applications.
Option A, Hardware of the AWS underlying infrastructure, is the responsibility of AWS, as mentioned earlier.
Option C, Database of the AWS infrastructure, is a shared responsibility between AWS and the customer, depending on the type of database service used. For example, with Amazon RDS, AWS manages the infrastructure and security of the database, while the customer is responsible for managing the database schema, data, and access controls.
Option D, Networking of the AWS infrastructure, is also a shared responsibility. AWS is responsible for the security and management of the network infrastructure, including firewalls, load balancers, and routing, while the customer is responsible for configuring and managing their own network and security groups.
