Palo Alto Networks (PANW) Certified Cybersecurity Entry-level Technician (PCCET) Practice Exam

If you are responsible for the application's security, but not the operating system's security, which cloud computing service model are you using?

1. A. Your own data center

2. B. IaaS

3. C. PaaS

4. D. SaaS

The correct answer is: C. PaaS

In the scenario described, where you are responsible for the application's security but not the operating system’s security, the correct service model being utilized is Platform as a Service (PaaS). PaaS provides a platform that enables developers to build, deploy, and manage applications without having to handle the underlying infrastructure or operating system. In this model, the cloud provider manages the operating system, including its security, allowing you to focus solely on your application's development and security measures. This arrangement empowers businesses to streamline their development processes while offloading certain responsibilities to the provider, particularly the management of the operating environment. In contrast, other models impose different responsibilities on users. For instance, in Infrastructure as a Service (IaaS), users are tasked with managing the operating system and its security while the provider manages the physical infrastructure. In Software as a Service (SaaS), applications are fully managed by the service provider, including both application and operating system security, limiting user responsibility primarily to managing their usage of the software. Managing your own data center indicates a complete responsibility for all aspects of security, including both application and operating system layers. Thus, the primary reason PaaS is the appropriate answer is that it differentiates your role in managing only the application
