MC-ABAC: An ABAC-based Model for Collaboration in Multi-Cloud Environment

Collaborative systems allow a group of organizations to collaborate and complete shared tasks through distributed platforms. Organizations who often leverage cloud-based solutions outsource their data benefit from the cloud capabilities. During such collaborations, tenants require access utilize resources held by other collaborating tenants, which are hosted across multiple providers. Ensuring control in collaborative application is crucial problem that needs be addressed, particularly multi-cloud environment. This paper presents Multi-Cloud ABAC: MC-ABAC model, an extension Attribute Based Access Control suitable for ensuring secure collaboration cross-tenant The introduces notions tenant, customer service provider as fundamental entities within model. Additionally, it incorporates trust relations enable resource sharing among To demonstrate its feasibility, we have implemented model using Python technology.
