Deploying ABAC policies using RBAC systems [PDF]

Journal of Computer Security, 2019
The flexibility, portability and identity-less access control features of Attribute Based Access Control (ABAC) make it an attractive choice to be employed in many application domains. However, commercially viable methods for implementation of ABAC do not exist while a vast majority of organizations use Role Based Access Control (RBAC) or their ...

Policy Engineering in RBAC and ABAC

2018
Role-based Access Control (RBAC) and Attribute-based access control (ABAC) are the most widely used access control models for mediating controlled access to resources in organizations. In RBAC, permissions are associated with roles, and users are assigned to appropriate roles.

Safety of ABAC $$_\alpha $$ Is Decidable

2017
The \(\mathrm {ABAC_\alpha }\) model was recently defined with the motivation to demonstrate a minimal set of capabilities for attribute-based access control (ABAC) which can configure typical forms of the three dominant traditional access control models: discretionary access control (DAC), mandatory access control (MAC) and role-based access control ...

A Category-Based Model for ABAC

Proceedings of the Third ACM Workshop on Attribute-Based Access Control, 2018
In Attribute-Based Access Control (ABAC) systems, access to resources is controlled by evaluating rules against the attributes of the user and the object involved in the access request, as well as the values of the relevant attributes from the environment.

An Abac for the Sample Range

Psychometrika, 1948
An abac is computed which gives the probability that at least q % of the whole population will be included in the range of a random sample of given size. Applications are suggested for testing homogeneity of a sampling from a given population.

ABAC Based Online Collaborations in the Cloud

2017
Nowadays sharing data among organizations plays an important role for their collaboration. During collaborations, the organizations need to access shared information while respecting the access control constraints. In addition, most organizations rely on cloud based solutions to store their data (e.g. openstack).

Mining ABAC Rules from Sparse Logs

2018 IEEE European Symposium on Security and Privacy (EuroS&P), 2018
Different methods have been proposed to mine attribute-based access control (ABAC) rules from logs. In practice, these logs are sparse in that they contain only a fraction of all possible requests. However, for sparse logs, existing methods mine and validate overly permissive rules, enabling privilege abuse. We define a novel measure, reliability, that
