Guide to Attribute-Based Access Control (ABAC)
Attribute-Based Access Control (ABAC) Attribute-based access control is a model inspired by role-based access control. The basis of the attribute-based access control is about defining a set of attributes for the elements of your system. This model comprises of several components....

CBDAC: Context-Based Dynamic Access Control Model Using ... the role hierarchy is a predefined static role, in dynamic environments such as context-aware, wireless computing, ... CRBAC [21] is a contextual role-based access control authorization model for electronic patient records (EPRs)....
A contextual role-based access control authorization model ...
Abstract: The design of proper models for authorization and access control for electronic patient record (EPR) is essential to a wide scale use of EPR in large health organizations. In this paper, we propose a contextual role-based access control authorization model aiming to increase the patient privacy and the confidentiality of patient data, whereas being flexible enough to consider ......
Contextual Privacy Management in Extended Role Based ...
So, data owner can define authorisations based on different object accuracies. Furthermore, access control models usually permit the access to the stored data based on the role of the requester. We propose to extend this concept to take into account the purpose of the access. For this, we take advantage of the OrBAC user-declared context....

Role-Based Access Control or RBAC is part of Snowflake’s Access Control Framework which allows privileges to be granted by Object Owners to Roles, and Roles, in turn, can be associated with ...

In practice however, many access-control implementations call themselves Role-Based, but do not adhere to the (NIST) RBAC model (at all). The ones that do implement the (NIST) RBAC model often implement Flat and Symmetric, but skip the Hierarchical and/or the SoD Constraints, because they are (a lot) harder to implement....
XACML v3.0 Core and Hierarchical Role Based Access Control ...
Role based access control. A model for controlling access to resources where permitted actions on resources are identified with roles rather than with individual subject identities. Role Enablement Authority. An entity that assigns role attributes and values to users or enables role attributes and values during a user's session. RPS. Role ......

Temporal role-based access control models support the specification and enforcement of several temporal constraints on role enabling, role activation, and temporal role hierarchies among others. In this paper, we define three mappings that preserve the solutions to a class of policy problems: they map security analysis problems in presence of ......
"Fine-grained role-based delegation in presence of the ...
However, these models consider delegation in presence of the general hierarchy type. Multiple hierarchy types have been proposed in the context of Generalized Temporal Role-based Access Control (GTRBAC) model, where it has been shown that multiple hierarchy semantics is desirable to express fine-grained access control policies....
Designing role‐based access control using formal concept ...
The main purpose of the access control policies is to ensure that only authorized users (subjects) can access the information resources (objects) with their allowed access permissions. Role‐based access control (RBAC) is one of the best access control models that supports function‐based access control....
