Overview #

• Imagine a client which is making a request to some service; it can make three types of request
  • getPublicInfo
  • getProtectedInfo
  • getConfidentialInfo
• The service needs to make a policy decision for each request - should it respond with the info, or respond with a "not permitted" error? It asks policy for information about how it should respond
