ACADA: Access Control-driven Architecture with Dynamic Adaptation
| Resumo: | Programmers of relational database applications use software solutions (Hibernate, JDBC, LINQ, ADO.NET) to ease the development process of business tiers. These software solutions were not devised to address access control policies, much less for evolving access control policies, in spite of their unavoidable relevance. Currently, access control policies, whenever implemented, are enforced by independent components leading to a separation between policies and their enforcement. This paper proposes a new approach based on an architectural model referred to here as the Access Controldriven Architecture with Dynamic Adaptation (ACADA). Solutions based on ACADA are automatically built to statically enforce access control policies based on schemas of Create, Read, Update and Delete (CRUD) expressions. Then, CRUD expressions are dynamically deployed at runtime driven by established access control policies. Any update in the policies is followed by an adaptation process to keep access control mechanisms aligned with the policies to be enforced. A proof of concept based on Java and Java Database Connectivity (JDBC) is also presented. |
