User authentication is the verification of the credentials of a user. User authorization determines the user's privileges and provides access control to the managed resources.
User privileges define the scope of managed resources for which a user has the right to perform a set of operations.
Cisco Voice Routing Center (VRC) Version 1.1 uses the Cisco Network Service (CNS) security service for user administration and authorization.
VRC uses the CNS security service for the following user administration and authorization operations:
User login
User logout
Check user permissions
Display user privileges
Create and delete security data when the network topology changes
For VRC system administration operations, use the VRC console.
