Model-Driven Integration and Analysis of Access-control Policies in Multi-layer Information Systems

The Tamago platform provides tools for static verifications of these contracts, generation of test scenarios from the abstract contracts and monitoring facilities for dynamic

the results shown in figures 6.12e and 6.12f: the time needed to make an access decision with respect to the number of sessions ranges from 49 ms to 72 ms for the assignment

To address this issue, we propose to refactor access control policies for performance improvement by splitting a policy (han- dled by a single PDP) into its corresponding

Contracts are in the form of precondition → post-condition. An activity can be associated with multiple contracts, representing different situations. In this paper,

For example, for case studies with manually written attribute data, when the actual log completeness is 80%, and the estimated completeness used to compute w o varies from 70% to

Given dynamic groups implementing user- attribute policies to resources and administrative units policies, we first model the user attribute-based access control system as a

Cette pra- tique se retrouve logiquement en visualisation scientifique : afin de comprendre la structure 3D d’un champ, scalaire par exemple, souvent les ing´enieurs vont soit

Dans le cas de notre exemple, nous souhaitons que l'utilisateur puisse dénir une direction dans laquelle il souhaite dépointer le lobe principal du réseau d'antenne, que cette
