Symantec Product Authorization Service

A common component, also known as VRTSaz, that provides a centralized access control decision-making service. After the Authentication Service has validated user identities, the Authorization Service makes access control decisions, determining whether specific users have the authority to perform specific tasks on specific resources being protected by authorization. The Hardware Abstraction Layer (HAL) is the only part of CommandCentral Storage to use the Authorization Service, using it to control access for inter-process communication.
