Access Control and Governance
CDP One access control and governance is managed by a shared set of security services. You must have the Security Admin role in order to access the CDP One security services.
Ranger access control and auditing
Ranger manages access control through a user interface that ensures consistent policy administration across cluster services.
Security administrators can define security policies at the database, table, column, and file levels, and can administer permissions for groups or individual users. Rules based on dynamic conditions such as time or geolocation can also be added to an existing policy rule. Ranger security zones enable you to organize service resources into multiple security zones.
Ranger also provides a centralized framework for collecting access audit history and reporting data, including filtering on various parameters.
