Abstract. Hierarchical representation is a natural way of organizing roles in role-based access control systems. Besides its advantages of providing a way of establishing parent-child relationships among different roles, it also provides a facility to design and organize context dependant application roles that users may activate depending on their current context (spatial, temporal) conditions....
Development of trust based access control models using ...
The access control system is designed with the help of algorithms, models, and administrative capabilities by which every access control system has its own methods, attributes, and capabilities to restrict the user’s access (Sun et al., 2011). The main aim of designing this model in a cloud platform is to secure the user’s computation and data....
Role-based access control - Wikipedia
In computer systems security, role-based access control (RBAC) or role-based security is an approach to restricting system access to authorized users. It is used by the majority of enterprises with more than 500 employees, and can implement mandatory access control (MAC) or discretionary access control (DAC). Role-based access control (RBAC) is a policy-neutral access-control mechanism defined ......
 A Design of Onto-ACM(Ontology based Access Control Model ...
Particularly, access control model is the most frequently used method for insider intrusion[3, 4, 21] de-tection and prevention. Generally, insider intrusion detection and prevention system is used RBAC(Role-Based Access Control) and C-RBAC(Context-Aware Role Based Access Control) models[6, 19]. How-...
Role-Based Access Control
Currently, we provide two ways of implementing role-based access control (RBAC), which you can use in place of or in combination with your API's own internal access control system: Authorization Core. Authorization Extension. We are expanding our Authorization Core feature set to match the functionality of the Authorization Extension.
A comprehensive modeling framework for role-based access ...
Access control systems can be grouped into three categories (Sandhu and Samarati, 1996): discretionary (DAC), mandatory (MAC), and role-based (RBAC). In DAC, access rights are directly assigned to each user; moreover, a user is the only entity that can control the access to her own object(s), by assigning access rights to other users....
Automated Model-Based Testing of Role-Based Access Control ...
Role-based access control is an important access control method for securing computer systems. A role-based access control policy can be implemented incorrectly due to various reasons, such as programming errors. Defects in the implementation may lead to unauthorized access and security breaches. To reveal access control defects, this paper presents a model-based approach to automated ......
Configuring Role-Based Access Control (RBAC)
Role-Based Access Control (RBAC) enables you to restrict system access to authorized users based on their assigned roles. Using the RBAC model, permissions to perform specific system operations are assigned to specific roles, and system users are granted permission to perform specific operations only through their assigned roles.
