For a data pipeline that spans multiple systems and requires end-to-end encryption to ensure data confidentiality, which strategy ensures that data remains encrypted throughout the process, only being decrypted by authorized end systems?

Real Exam

Utilize transport layer security (TLS) across all components of the pipeline, relying on network encryption to secure data in transit.

10.9%

Implement format-preserving encryption to maintain data usability across the pipeline while ensuring that data is encrypted at rest and in transit, with decryption keys accessible only within secure execution environments.

9.1%

Apply a uniform encryption standard (e.g., AES) at the source and manage encryption keys through a centralized key management system, allowing only authorized services to access decryption keys based on their roles.

67.3%

Encrypt data at the source using public key infrastructure (PKI), ensuring that only the destination system has the corresponding private key for decryption.
