Which cloud security control eliminates the risk of a virtualization guest escape from another tenant?

A dedicated hosting environment is highly effective in mitigating the risk of virtualization guest escape, where one tenant could potentially access or interfere with another tenant's data or virtual machines. In a dedicated hosting setup, the physical server resources are exclusively allotted to a single client or tenant. This significantly reduces the risk of attacks stemming from shared resources, as there are no other tenants on the same hardware, making it much harder for a malicious actor to exploit vulnerabilities in the virtualization layer to escape to another tenant's environment.

A hardware hypervisor, while also offering a layer of isolation between virtual machine instances, still operates in a multi-tenant environment where multiple virtual machines may reside on the same physical hardware. This can expose systems to certain risks associated with virtualization escapes if vulnerabilities exist.

File integrity monitors focus on detecting unauthorized changes to files and might not directly address the inherent risks associated with multi-tenancy and virtualization guest escape.

Immutable virtual machines are designed to ensure that the state of a virtual machine does not change over time, which can improve security by reducing the attack surface. However, they do not eliminate the risk of guest escape since the underlying infrastructure may still be shared among multiple tenants.

Thus, dedicated hosting stands out as the control that fundamentally removes the risk of guest escape by
