The explosive growth of the Web, the increasing popularity of PCs and the advances in high-speed network access have brought distributed computing into the mainstream. To simplify network programming and to realize component-based software architecture, distributed object models have emerged as standards. One of those models is distributed component object model (DCOM) which is a protocol that enables software components to communicate directly over a network in a reliable, and efficient manner. In this paper, we investigate an aspect of DCOM concerning software architecture and security mechanism. Also, we describe the concept of role-based access control (RBAC) which began with multi-user and multi-application on-line systems pioneered in the 1970s. And we investigate how we can enforce the role-based access control as a security provider within DCOM, specially in access security policy.
