Your question is Secure Sensitive Data. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
What approaches do you take to secure sensitive financial data at rest and in transit?
Answer in the context of a production data pipeline. Explain how you would protect data across ingestion, processing, staging, analytical storage, and downstream consumers. Address encryption key management, TLS or mutual TLS, secrets handling, access control, masking or tokenization, auditability, rotation, and recovery. Include the controls you would implement in technologies such as Apache Kafka, Apache Spark, Amazon S3, Snowflake, and Apache Airflow, and describe how you would monitor for misconfiguration, unauthorized access, and failed encryption requirements.
