Authorization

Explanation:
Authorization determines who is trusted for a given purpose. More precisely, it
determines whether a particular principal, who has been authenticated as the source of
a request to do something, is trusted for that operation. Authorization may also
include controls on the time at which something can be done (e.g. only during working
hours) or the computer terminal from which it can be requested (e.g. only the one on
the system administrator desk).
