From Business Process Choreography to Authorization Policies
A choreography specifies the interactions between the resources of multiple collaborating parties at design time. The runtime management of authorization policies in order to support such a specification is however tedious for administrators to manually handle. By compiling the choreography into enhanced authorization policies, we are able to automatically derive the minimal authorizations requ...
متن کاملAuthorization Policies for Materialized Views
In this paper, we propose a novel approach to facilitate the administration of access control policies to ensure the confidentiality of data at the level of materialized views. A materialized view stores both the definition of the view and the rows resulting from the execution of the view. Several techniques and models have been proposed to control access to databases, but to our knowledge the ...
متن کاملAnalysis of Communicating Authorization Policies
We present a formal language for specifying distributed authorization policies that communicate through insecure asynchronous media. The language allows us to write declarative authorization policies; the interface between policy decisions and communication events can be specified using guards and policy updates. The attacker, who controls the communication media, is modeled as a message deduct...
متن کاملOptimal Storage Aware Caching Policies for Content-Centric Clouds
Caches in Content-Centric Networks (CCN) are increasingly adopting flash memory based storage. The current flash cache technology stores all files with the largest possible “expiry date,” i.e. the files are written in the memory so that they are retained for as long as possible. This, however, does not leverage the CCN data characteristics where content is typically short-lived and has a distin...
متن کاملTransforming Prior Authorization to Decision Support.
PURPOSE To evaluate a computer-based prior authorization system that was designed to include and test two new concepts for physician review: (1) the tool would minimize denials by providing real-time decision support with alternative options if the original request was noncompliant, and (2) the tool would collect sufficient information to create a patient registry. METHODS A new prior authori...
