Formal Description for an Object-Oriented Role-based Access Control Model
Role-based access control(RBAC) is a promising technology for managing and enforcing security in large-scale enterprise-wide system, and we were motivated by the need to manage and enforce the strong access control technology of RBAC in large-scale Web environments. Majority of traditional access control models were passive data-protections, which were not suitable for large and complex multi-u...
متن کاملA Purpose-Oriented Access Control Model for Object-Based Systems
Distributed applications are modeled in an object-based model like CORBA [1]. Here, the system is a collection of objects. The objects are manipulated only through operations supported by themselves. The purpose-oriented model [2] is proposed where an access rule shows for what each subject s manipulates an object o by an operation t of o so as to keep the information flow legal. The purpose of...
متن کاملAn Object-Oriented Organizational Model to Support Dynamic Role-based Access Control in Electronic Commerce Applications
Role-based access control (RBAC) provides flexibility to security management over the traditional approach of using user and group identifiers. In RBAC, access privileges are given to roles rather than to individual users. Users acquire the corresponding permissions when playing different roles. Roles can be defined simply as a label, but such an approach lacks the support to allow users to aut...
متن کاملA Formal Model for Flat Role-Based Access Control
Role-Based Access Control (RBAC) is very useful for providing a high level description of access control. It enables a better understanding of the security problems in an institution because it bridges the gap between their technical aspects and their managerial descriptions. Several models have been devised to describe RBAC. However, the definitions of some of the concepts of RBAC, such as sub...
متن کاملPurpose-Oriented Access Control Model in Object-Based Systems
In distributed applications, a group of multiple objects are cooperating to achieve some objectives by exchanging messages through communication networks. An object is modeled as a pair of data structure and operations. In the cooperation among multiple objects, it is important to protect against illegal information ow among the objects. In this paper, we discuss an access control model for an ...
