Have you worked with PII data? How do you handle that information?

PII data requires strict protection. First, classify the data to understand sensitivity and regulatory obligations (GDPR, CCPA, HIPAA). Store PII encrypted at rest using strong algorithms (AES‑256) and encrypt in transit with TLS. Use key management services (e.g., AWS KMS, Azure Key Vault) to rotate keys regularly. Apply role‑based access control so only authorized users can view or modify PII. For data that can be anonymized, use tokenization or hashing; for data that must remain readable, use dynamic masking or column‑level encryption. Implement audit logging to track access and modifications. When moving PII between systems, use secure transfer mechanisms (SFTP, HTTPS, or managed data pipelines) and avoid storing plaintext in logs. Finally, enforce data retention policies and secure deletion (Wipe, shred) when data is no longer needed. These practices help meet compliance requirements and protect user privacy.
