Analysis of enhanced separation of duty in role-based access control model

Separation of duty is an important constraint in role-based access control model and is used to resolve interest conflicts among roles. Enhanced separation of duty (ESoD) defines not only SoD on roles but also SoDs on permissions, operations, objects and even users. Further more, ESol) defines conflict transfers in RBAC model elements and role hierarchy which constructed relationships among above isolated SoDs. we comprehensively and formally describe above concepts in ESoD.Computer Science, Artificial IntelligenceComputer Science, Information SystemsComputer Science, Software EngineeringImaging Science & Photographic TechnologyTelecommunicationsCPCI-S(ISTP)
