Emergency role-based access control (E-RBAC) and analysis of model specifications with alloy
Journal of Information Security and Applications, 2019Abstract In role-based access control (RBAC), users gain access to predetermined roles and permissions. Thus, desired results are not achieved in emergency situations through policy in RBAC. In emergency situations, users should sometimes gain access to resources not authorized in normal situations.

Owner-Based Role-Based Access Control OB-RBAC
2010 International Conference on Availability, Reliability and Security, 2010Administration of an access control model deals with the question of who is authorized to update policies defined on the basis of that model. One of the models whose administration has absorbed relatively large research is the Role-Based Access Control (RBAC) model.

uT-RBAC: Ubiquitous Role-Based Access Control Model
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2006In ubiquitous environment that users access resource anytime and anywhere, access control model should consider user's location information. The proposed uT-RBAC includes the location information for user's least privilege. It also supports time related information, which enables the access control model to accommodate various ubiquitous environments ...

GenericWA-RBAC: Role Based Access Control Model for Web Applications
9th International Conference on Information Technology (ICIT'06), 2006Web applications involve the operations on the data objects across the organization boundaries. The operations are provided by the organization once the partners are identified. Web services are globally accepted and are adopted in any web application. The serious threat in web services is security, as these services are available to open world.

An empirical assessment of approaches to distributed enforcement in role-based access control (RBAC)
Proceedings of the first ACM conference on Data and application security and privacy, 2011We consider the distributed access enforcement problem for Role-Based Access Control (RBAC) systems. Such enforcement has become important with RBAC's increasing adoption, and the proliferation of data that needs to be protected. We assess six approaches, each of which has either been proposed in the literature, or is a natural candidate for access ...

UC-RBAC: A Usage Constrained Role-Based Access Control Model
2003Role-based access control (RBAC) models have received broad support as a generalized approach to access control. However, there are requirements to limit the maximum number of usage times of roles assigned to users, that cannot be modeled under current RBAC models. We present UC-RBAC model, an extended RBAC model, to tackle such dynamic aspects.

Management Advantages of Object Classification in Role-Based Access Control (RBAC)
2007This paper investigates the advantages of enabling object classification in role-based access control (RBAC). First, it is shown how the merits of the RBAC models can be ascribed to its using of abstraction and state of dependencies. Following same arguments, it is shown how inclusion of object classification will ameliorate dependencies and ...

An application of directory service markup language (DSML) for role-based access control (RBAC)
Proceedings 26th Annual International Computer Software and Applications, 2003The directory service markup language (DSML) prescribes how to manipulate directory services information in XML, and thus it facilitates sharing of directory information as XML fragments among XML-based applications. We describe how to leverage DSML for role-based access control on XML-based Web applications which often need collaboration within or ...
