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

A community cloud is shared among several organizations with common concerns, which introduces a higher risk of data leakage due to shared infrastructure, potential policy discrepancies, and broader access compared to a fully isolated private cloud.

A public cloud is available to the general public over the internet, with resources shared among multiple tenants, inherently increasing the probability of data leakage due to shared infrastructure and multi-tenancy, despite robust security measures implemented by providers.

A hybrid cloud combines private and public cloud elements; while it offers some benefits of private clouds for sensitive data, the inclusion of public cloud components still introduces shared risks and a higher potential for data leakage than a purely private cloud environment.

A private cloud is dedicated solely to one organization, with the infrastructure and services maintained on a private network, providing exclusive control over data, security policies, and physical access. This isolation and dedicated control significantly reduce the attack surface and potential for data leakage compared to environments where resources are shared among multiple entities.
