BigData / Data Lake Interview questions

How do you ensure compliance (GDPR, CCPA, HIPAA) in Data Lakes?

Compliance in data lakes requires identifying sensitive data, implementing controls, and maintaining audit trails. GDPR requires data minimization, consent tracking, right to access/deletion, breach notification. CCPA requires disclosure of data collection, opt-out rights, deletion on request. HIPAA requires encryption, access controls, audit logs for healthcare data. Implementation: classify data (PII, PHI, PCI tags), encrypt at rest and in transit, implement row/column-level security, log all access, automate deletion requests, maintain consent records, conduct regular audits. Tools: Azure Purview, AWS Macie (PII detection), Apache Ranger (access control).
