Cloud EKM is ideal when regulatory or trust requirements demand that encryption keys never reside on the cloud provider’s infrastructure. It allows integration with third-party key managers while maintaining control over encryption. CSEKs also ensure key control but place full operational burden (e.g., delivery, rotation, loss prevention) on the customer. EKM allows for a more scalable and auditable model, whereas CSEKs increase risk due to manual key handling and potential data loss if keys are mismanaged.
182
How does Google Cloud’s implementation of BeyondProd extend zero trust principles beyond user access to the runtime environment, and how is this different from traditional perimeter-based security models?
BeyondProd applies zero trust to the production environment by treating all inter-service communication as untrusted. It enforces strong service identity, mutual authentication, policy-driven access control, and continuous verification throughout the lifecycle of microservices. Unlike perimeter models that assume trust within the firewall, BeyondProd treats every service, even internal, as a potential threat vector, ensuring isolation, attestation, and authorization across all runtime and deployment layers.
