• A Role is a single system privilege, e.g. admin, user and so on. A subject can have zero or more roles.
• A Permission is a can be used with regular expression matching, e.g. a subject with a permission of printers.admin can access a resource constrained to printers., .admin, etc. A subject can have zero or more permissions.
