A method and system is provided for assessing the cumulative set of access entitlements to which an entity, of an information system, may be implicitly or explicitly authorized, by virtue of the universe of authorization intent specifications that exist across that information system, or a specified subset thereof, that specify access for that entity or for any entity collectives with which that entity may be directly or transitively affiliated. The effective system-level access granted to the user based upon operating system rules or according to access check methodologies is determined and mapped to administrative tasks to arrive at the cumulative set of access entitlements authorized for the user.
