Abstract

The access control paradigm has been changing in the past years, specially what regards the access control to information. Information access control was originally achieved independently by each application without querying or interacting with a central system. However, due to the increasing usage of information technologies, new solutions (such as LDAP services) have been put in place in order to obtain a unified access policy across different services and applications. These solutions greatly improve the performance of organizational tasks.

This project aims to present a new access control solution for both physical and logical layers. Therefore, a new access control model based on the pair Role/Organization is presented, as well as a concrete implementation of this model. Bearing in mind that not all applications support access control protocols, another approach (which allows the interaction with these applications) is also taken. In this context, after presenting the conceptual organization of the proposed solution, along with some implementation details, some illustrative evaluation tests are also presented and discussed.
