Data security doesn't only apply using tools efficiently. The data flows from point ORIGIN to point DESTINATION and is stored on point STORAGE to be manipulated, stored or tracked. ORIGIN to STORAGE and STORAGE to DESTINATION must follow encryption patterns to guarantee the data transferred is secured and difficult to intercept, apply security protocols, and so on. Finally, STORAGE must ensure it's only accessible when needed and only for a certain amount of users / systems. That control must be monitored to guarantee no external access is granted. If the system STORAGE is a non production system, data masking can help to prevent the data to be red by external attackers.

By implementing a robust authorization framework in data engineering, organizations can maintain data security, compliance with regulations, and control over access to sensitive information. Regular assessments and updates to authorization policies are essential for adapting to changing business requirements and ensuring ongoing data protection.
