Authorization Overview

The access control in the grid and in grid applications relies on access policies. The access control process can be divided into two steps:

1. Policy definition, where each method in each grid proxy and web service in the grid and grid applications may define the authorization level required to use each individual function.

2. Policy enforcement, where access requests are approved or rejected based on the required authorization level of the called method and the assigned roles of the caller.

Authorization is the function where access requests are approved or rejected based on the previously defined authorization levels.

See the documentation for each grid application for details on what roles there are for that specific application, and what the roles are used for.
