When tenants deploy applications under the control of third-party cloud providers, they must trust the provider's security mechanisms for inter-tenant isolation, resource sharing and access control. Despite a provider's best efforts, accidental data leakage may occur due to misconfigurations or bugs in the cloud platform. Especially in Platform-as-a-Service (PaaS) clouds, which rely on weaker forms of isolation, the potential for unnoticed data leakage is high. Prior work to raise tenants' trust in clouds relies on attestation, which limits the management flexibility of providers, or fine-grained data tracking, which has high overheads.
