Authorization recycling in RBAC systems [PDF]
Proceedings of the 13th ACM symposium on Access control models and technologies, 2008 As distributed applications increase in size and complexity, traditional authorization mechanisms based on a single policy decision point are increasingly fragile because this decision point represents a single point of failure and a performance bottleneck. Authorization recycling is one technique that has been used to address these challenges.

A Design of MAC Model Based on the Separation of Duties and Data Coloring: DSDC-MAC [PDF]
, 2020 Among the access control methods for database security, there is Mandatory Access Control (MAC) model in which the security level is set to both the subject and the object to enhance the security control. Legacy MAC models have focused only on one thing,

Extended privilege inheritance in RBAC [PDF]
Proceedings of the 2nd ACM symposium on Information, computer and communications security, 2007 In existing RBAC literature, administrative privileges are inherited just like ordinary user privileges. We argue that from a security viewpoint this is too restrictive, and we believe that a more flexible approach can be very useful in practice. We define an ordering on the set of administrative privileges, enabling us to extend the standard privilege

A Model-driven Role-based Access Control for SQL Databases
Complex Systems Informatics and Modeling Quarterly, 2015 Nowadays security has become an important aspect in information systems engineering. A mainstream method for information system security is Role-based Access Control (RBAC), which restricts system access to authorised users.

Dynamic deployment of context-aware access control policies for constrained security devices [PDF]
, 2009 Securing the access to a server, guaranteeing a certain level of protection over an encrypted communication channel, executing particular counter measures when attacks are detected are examples of security requirements.

Authorization algorithms for permission-role assignments [PDF]
, 2009 Permission-role assignments (PRA) is one important process in Role-based access control (RBAC) which has been proven to be a flexible and useful access model for information sharing in distributed collaborative environments.

Towards user-oriented RBAC model [PDF]
Journal of Computer Security, 2013 Role mining is to define a role set to implement the role-based access control (RBAC) system and regarded as one of the most important and costliest implementation phases. While various role mining models have been proposed, we find that user experience/perception – one ultimate goal for any information system – is surprisingly ignored by the existing
