Developer details technical requirements for compliant data audit workbench

A developer writing for DEV Community argues that effective data audit systems should focus on creating immutable evidence pipelines rather than dashboards. They recommend capturing specific control events like access, export, and deletion in a hash-chained, append-only format to prove sequence integrity. Practical implementation requires object storage with write-once-read-many (WORM) locks and long retention periods, though this increases costs. The author also addresses challenges like handling high-throughput events and reconciling immutable logs with data erasure requests through technical patterns like salting personal data keys.
