Answer
Avoid sending PII or sensitive fields.
Use DTOs, masking, or encryption.
Always enforce HTTPS.
Quick Answer
Secure sensitive data in responses: never return passwords or hashed passwords. Exclude PII fields not needed by the client (use [JsonIgnore] or response DTOs). Mask sensitive fields (show last 4 digits of card). Encrypt sensitive data stored in DB. Use HTTPS to protect in-transit data. Implement field-level encryption for highly sensitive fields. Audit access to sensitive data endpoints.
