Which of the following cloud delivery models has the LEAST probability of data leakage?

A community cloud shares infrastructure among multiple organizations with similar interests, introducing some risk of data leakage between member organizations that does not exist in a private cloud.

A public cloud shares infrastructure among many unrelated tenants managed by a third-party provider, creating the highest exposure to data leakage through misconfiguration or provider-side vulnerabilities.

A hybrid cloud combines private and public cloud environments, inheriting the data leakage risks associated with the public cloud component.

In a private cloud, all hardware, storage, and networking resources are used solely by one organization and are not shared with any external tenants. This isolation removes the risk of data exposure through shared infrastructure vulnerabilities, misconfigured multi-tenant environments, or unauthorized cross-tenant access, making it the cloud delivery model with the lowest data leakage probability.
