Didi's Big Data Security Permission System: User Authentication and Column-Level Authorization
Didi’s big‑data platform secures user access by adding a custom password‑based Hadoop authentication stored on the NameNode and managed through its Shumeng user‑management service, while enforcing column‑level, role‑based permissions via an Apache Ranger‑powered system that classifies data, generates policies, and now governs millions of assets.
