Flexible Enterprise Access Control with Object-oriented View Specification

The per-method access control lists of standard middleware technologies allow only simple forms of access control to be expressed and enforced. Given the increasing use of web-based applications involving sensitive data, the increased threat and the stringent requirements of privacy laws, a more flexible and secure approach is needed. In this paper we present a three-step approach to access control involving object-oriented encapsulation, middleware based on a new, more secure access control mechanism and the high-level specification of method-oriented views. We demonstrate the use of the approach in a simple web-based E-commerce environment to provide secure electronic cheques.
