A data lake holds everything—structured tables, unstructured logs, mutable streams. Without tight control, it becomes a hazard. MSA Access Control enforces rules at scale, ensuring only the right identities touch the right assets.
Access control in MSA means policy-driven permissions. Policies define actions: read, write, delete, query. They bind to identities—users, services, API keys. MSA uses fine-grained controls so even within a single dataset, some fields are visible while others stay locked. This prevents leaks and maintains compliance.
Integration with authentication systems is core. Identity proof flows through OAuth, SAML, or native tokens. Once verified, MSA checks each request against lake policies. This works for batch jobs, interactive queries, and streaming ingest calls. Granularity extends to row-level filtering, column masking, and conditional writes.
Auditing is not optional. MSA Data Lake Access Control logs every access, decision, and denial. These records feed security analytics, detect anomalies, and satisfy regulatory audits. For high-security environments, policies can enforce multi-factor authentication before granting access to sensitive datasets.
