Explanation

In an IaaS model, the cloud service provider is responsible for managing the underlying physical infrastructure, networking, and hypervisor, as well as the platform instances they operate to run the IaaS service itself. A vulnerability assessment scoped to the CSP's infrastructure will scan only the application infrastructure within the CSP's own managed instances (e.g., management plane applications, control plane services) - not the customer's VM instances. Customers are responsible for the OS and applications within their own virtual machines; those are outside the CSP's scanning scope in a standard IaaS engagement.
