Attribute Based Access Control for Healthcare Resources
Proceedings of the 2nd ACM Workshop on Attribute-Based Access Control, 2017Fast Health Interoperability Services (FHIR) is the most recent in the line of standards for healthcare resources. FHIR represents different types of medical artifacts as resources and also provides recommendations for their authorized disclosure using web-based protocols including O-Auth and OpenId Connect and also defines security labels.

On Completeness in Languages for Attribute-Based Access Control
Proceedings of the 21st ACM on Symposium on Access Control Models and Technologies, 2016Attribute-based access control (ABAC) has attracted considerable interest in recent years, resulting in an extensive literature on the subject, including the standardized XML-based language XACML. ABAC policies written in languages like XACML have a tree-like structure in which leaf nodes are associated with authorization decisions and non-leaf nodes ...

Attribute Transformation for Attribute-Based Access Control
Proceedings of the 2nd ACM Workshop on Attribute-Based Access Control, 2017In this paper, we introduce the concept of transforming attribute-value assignments from one set to another set. We specify two types of transformations---attribute reduction and attribute expansion. We distinguish policy attributes from non-policy attributes in that policy attributes are used in authorization policies whereas the latter are not ...

Combining Mandatory and Attribute-Based Access Control
2016 49th Hawaii International Conference on System Sciences (HICSS), 2016Attribute based access control (ABAC) offers a great deal of flexibility over more traditional forms of access control in that it relies less on user identity or role but on various attributes of a subject or object. In many instances where a traditional access control approach is taken, such as mandatory access control (MAC) environments, more ...

Supporting attribute-based access control with ontologies
First International Conference on Availability, Reliability and Security (ARES'06), 2006In highly open systems like the Internet, attribute-based access control (ABAC) has proven its appropriateness. The specification and maintenance of ABAC policies however has turned out to be complex and error-prone, especially if heterogeneous attribute schemes are involved. Here, the arising semantic Web can contribute to a solution.

A Contextual Attribute-Based Access Control Model
2006The emergence of ubiquitous mobile devices, such as MP3 players, cellular phones, PDAs, and laptops, has sparked the growth of rich, mobile applications Moreover, these applications are increasingly “aware” of the user and her surrounding environment Dynamic mobile environments are generating new requirements – such as allowing users to access real ...

Attribute based access control for APIs in spring security
Proceedings of the 19th ACM symposium on Access control models and technologies, 2014The widespread adoption of Application Programming Interfaces (APIs) by enterprises is changing the way business is done by permitting the implementation of a multitude of apps, customized to user needs. While supporting a more flexible exploitation of available data, services and applications developed on top of APIs are vulnerable to a variety of ...

Monotonicity and Completeness in Attribute-Based Access Control
2014There have been many proposals for access control models and authorization policy languages, which are used to inform the design of access control systems. Most, if not all, of these proposals impose restrictions on the implementation of access control systems, thereby limiting the type of authorization requests that can be processed or the structure ...
