DARBAC: Dynamically Administering Role Based Access Control
Access control administration regulates and enforces the definition of the components of an access control system by authorized administrative users. In this paper, the limitations on administrative aspects of well-known security models are addressed and the requirements for efficient management of authorizations are investigated in order to provide fine-grained and just-in-time access control ...
متن کاملTask - and - role - based access - control model for computational grid ∗
Access control in a grid environment is a challenging issue because the heterogeneous nature and independent administration of geographically dispersed resources in grid require access control to use fine-grained policies. We established a task-and-role-based access-control model for computational grid (CG-TRBAC model), integrating the concepts of role-based access control (RBAC) and task-based...
متن کاملAttribute Based Access Control for Grid Computing
Grid systems, which are composed of autonomous domains, are open and dynamic. In such systems, there are usually a large number of users, the users are changeable, and different domains have their own policies. The traditional access control models that are identity based are closed and inflexible. The Attribute Based Access Control (ABAC) model, which makes decisions relying on attributes of r...
متن کاملRole-Based Access Control for Model-Driven Web Applications
The Role-based Access Control (RBAC) model provides a safe and efficient way to manage access to information of an organization, while reducing the complexity and cost of security administration in large networked applications. However, Web Engineering frameworks that treat access control models as first-class citizens are still lacking so far. In this paper, we integrate the RBAC model in the ...
متن کاملExtending Role Based Access Control Model for Distributed Multidomain Applications
This paper presents the results related to the development of a flexible domain-based access control infrastructure for distributed Grid-based Collaborative Environments and Complex Resource Provisioning. The paper proposes extensions to the classical RBAC model to address typical problems and requirements in the distributed hierarchical resource management such as: hierarchical resources polic...
