A single global security policy structure usually meets company security needs. However, some companies may need to configure both global and local policies. For example:
Assume that a company has three semi-independent divisions, Human Resources, Development, and Marketing.
All three divisions store information on the same Teradata Database system.
Each division has a dedicated directory service to independently manage its users.
Human Resources deals with sensitive information about employees and needs to enforce a strict, local QOP (encryption) policy on their users.
Development and Marketing share security policy requirements so they can share the same global policy structure, whereas Human Resources requires a separate local policy structure.
