Authorization refers to the granting of specific types of service (including "no service") to a user, based on their authentication, what services they are requesting, and the current system state. Authorization may be based on restrictions, for example time-of-day restrictions, or physical location restrictions, or restrictions against multiple logins by the same user. Authorization determines the nature of the service which is granted to a user. Examples of types of service include, but are not limited to:

  • IP address filtering;
  • address assignment;
  • route assignment;
  • QoS/differential services;
  • bandwidth control/traffic management;
  • compulsory tunneling to a specific endpoint;
  • encryption.
