Teradata Secure Zones allow you to create one or more exclusive database hierarchies, called zones, within a single Teradata database system. Access to the data in each zone and zone administration is handled separately from the Teradata database system and from other zones. Each zone can have a DBA for that zone.
Teradata Secure Zones are useful in situations where the access to data must be tightly controlled and restricted. You can also use Teradata Secure Zones to support some regulatory compliance requirements for the separation of data access from database administration duties. Other uses include separating and securing data by corporate division or by cloud storage tenant.
