OrBAC.org : modélisation de politiques de sécurité
by clochix
L'objectif d' OrBAC est de permettre la modélisation d'une variété de politiques de sécurité basées sur le contexte de l'organisation. Pour arriver à ce but, et afin de réduire la complexité de gestion des droits d'accès, le modèle OrBAC repose sur quatre grands principes :
* L’organisation est l’entité centrale du modèle
* Il y a deux niveaux d’abstraction (cf. Les interactions d'OrBAC) :
un niveau concret : sujet , action, objet
un niveau abstrait : rôle, activité, vue
* La possibilité d'exprimer des permissions, des interdictions, et des obligations
* La possibilité d'exprimer les contextes

Policy based access control for an RDF store
by benoit
Resource Description Format (RDF) stores have formed an essential part of many semantic web applications. Current RDF store systems have primarily focused on efficiently storing and querying large numbers of triples. Little attention has been given to how triples would be updated and maintained or how access to store can be controlled. In this paper we describe the motivation for an RDF store with complete maintenance capabilities and access control. We propose a policy based access control model
providing control over the various actions possible on an RDF store. Finally, we discuss on how the Hypertext Transport Protocol (HTTP) and its extensions can be used to provide communication with the store.
