Abstract
A method of determining whether to authorize a user of a computer system to perform an action in the computer system is described. Besides the explicit authorization grants, a new, more secure semantics is defined where only unassigned users or actions are granted generically. For example, if an access control list for an action is not empty, a user may be authorized to perform the action only if the user is a member of the access control list for the action. If the access control list for the action is empty, the user may be authorized to perform the action only if the user is not a member of any access control list of a group of access control lists.
