eGovernment Security Requirements: Managing Obligations and Authorizations Inconsistencies with XACMLv3
Résumé
Today, many governments tend to propose e-services to their citizens. However, implementing an eGovernment environment shall face up to several security challenges including integrating security requirements coming from multiple stakeholders. In this article, we analyze the conflicts that can occur between eGovernment security requirements. Since these security requirements can contain both authorizations and obligations, we cover these two aspects. Then, we propose a new conflict resolution algorithm that handles conflicts between authorizations as well as obligations. This work has been implemented in XACMLv3.
