Which cloud service model lets you install a firewall to protect your information?

1. SaaS

2. PaaS

3. FaaS

4. IaaS

The correct answer is: IaaS

The Infrastructure as a Service (IaaS) model is the correct choice because it provides users with virtualized computing resources over the internet. In the IaaS model, customers have the ability to manage and control the underlying infrastructure, including the setup of firewalls and other security measures to protect their data and applications. This level of control allows for the customization of security settings to fit specific organizational needs, such as configuring virtual firewalls, intrusion detection systems, and other protective mechanisms. In contrast, Software as a Service (SaaS) is designed to offer fully managed applications where security is largely handled by the service provider, limiting the user's control over security specifics like firewall configurations. Platform as a Service (PaaS) also provides managed environments for application development and deployment, but it does not give customers full control over the underlying infrastructure necessary for firewall installation. Function as a Service (FaaS) is focused on serverless computing and typically abstracts away the infrastructure management entirely, leaving no opportunity for users to install a firewall. Hence, IaaS is the only model that enables users to directly install firewalls to safeguard their information.
