CompTIA CASP+ CAS-004: Which is customer’s responsibility in shared responsibility model for PaaS

Question

In a shared responsibility model for PaaS, which of the following is a customer’s responsibility?

A. Network security
B. Physical security
C. OS security
D. Host infrastructure

Answer

C. OS security

Explanation

The correct answer is C. OS security.

OS security is the customer’s responsibility in a shared responsibility model for PaaS. PaaS stands for Platform as a Service, which is a cloud service model that provides customers with a platform to develop, run, and manage applications without having to manage the underlying infrastructure. In a shared responsibility model, the cloud provider and the customer share the responsibility for different aspects of the cloud service, such as security, compliance, and availability.

According to the CompTIA CASP+ CAS-004 Certification Guide, the shared responsibility model for PaaS is as follows:

  • The cloud provider is responsible for:
    • Physical security: The protection of the physical facilities, equipment, and personnel that host the cloud service.
    • Host infrastructure: The provision and maintenance of the servers, storage, network, and virtualization components that support the cloud service.
    • Network security: The protection of the network devices, protocols, and traffic that enable the communication between the cloud service and the customer.
    • Platform security: The protection of the application development tools, frameworks, and middleware that are provided by the cloud service.
  • The customer is responsible for:
    • OS security: The protection of the operating system that runs on the virtual machines or containers that host the customer’s applications.
    • Application security: The protection of the application code, data, and logic that are developed and deployed by the customer.
    • Data security: The protection of the data that are stored, processed, or transmitted by the customer’s applications.

The other options are incorrect because:

  • A. Network security. This is false because network security is the cloud provider’s responsibility in a shared responsibility model for PaaS. The cloud provider is responsible for securing the network infrastructure and traffic that connect the cloud service and the customer.
  • B. Physical security. This is false because physical security is the cloud provider’s responsibility in a shared responsibility model for PaaS. The cloud provider is responsible for securing the physical facilities and equipment that host the cloud service.
  • D. Host infrastructure. This is false because host infrastructure is the cloud provider’s responsibility in a shared responsibility model for PaaS. The cloud provider is responsible for providing and maintaining the servers, storage, network, and virtualization components that support the cloud service.
