Authentication and authorisation are often thought of as a single process but the two are actually distinct operations that may even use separate storage locations for the authentication and authorisation data. Authentication is about verifying identity, based on one or more factors, for example something that someone knows (e.g. a password), something that someone holds (e.g. a smart card), something that someone is (e.g. biometric information). Obviously the use of multiple-factor identification increases security. Authorisation is about controlling access to a resource based on access control lists and other policies; however secure authorisation is dependant on authentication in order to ensure that the security principle requesting access is who they say they are.
