“…Then, different extensions of this model were made in order to keep access control between several organizations. Among these models, we mention: Poly-OrBAC [10], Multi-OrBAC [11], O2O [12], Virtual Organization [13]. But, there are some other security issues, for example the production of malicious activities, and the necessity of collaboration between unknown organizations.…”

In last decades, the notion of collaborative systems is presented as the new concept in Critical Infrastructures. It regroups different organizations collaborating in order to ensure the continuity of these infrastructures. However, some malicious behavior can arise causing perturbations on the information systems of the organizations. To avoid this behavior, building trust between collaborating organizations is necessary; it allows cooperating and sharing resources in a secure way. In this paper, we present Tr-OrBAC: a new trust model applicable in collaborative systems; it is based on the OrBAC (Organization Based Access Control) access control model and trust evaluation. In this paper, we will focus on explaining and detailing the proposed trust model.

“…These approaches enforce access control policies to organize different external users access to own resources, according to the several rules used by the collaborative models such as Poly-OrBAC [6], Multi-OrBAC [7], O2O [8], Virtual Organization [9]. However, these approaches don't allow collaboration management among unknown organizations.…”

Critical Infrastructures protection becomes increasingly important in recent decades. Particularly, those organizations should collaborate to share resources, services and exchange information and data, in order to ensure their continuity and success. By creating collaborative systems, we need to secure them against any malicious activities and destruction of their information systems. In this paper, we propose a new approach, named Trust-PolyOrBAC, for Trust Management in collaborative systems in critical infrastructures. Our approach integrates a trust concept in a PolyOrBAC access control model. Our aim is to establish trust between organizations during collaboration process, ensuring an access control to each resource and data. First, we present Trust-PolyOrBAC architecture. Then, we choose the Electrical Grid case study as a Critical Infrastructure in order to illustrate our approach and we present different parameters used to establish trust.

“…Assuming that each trust domain controls its own policies independently (using Local Roles), the use of a Global Role (common to a VO) is proposed as an interface among Local Roles. An extension of RBAC is presented in Reference 47 permitting the expression of contextual permissions and the abstraction of the different entities (users, actions and roles) in order to separate policies from the dynamic infrastructure. However, the former approach loses efficiency as the number of VOs increases, while the latter proposes an explicit abstraction process that is not appropriate for dynamic coalitions.…”

Interoperable semantic access control for highly dynamic coalitions

A coalition consists of independent organizations that share resources and skills to achieve significant mission objectives. Dynamic Coalition (DC) formations occur in response to some market demands, business requests, or disaster responses, to name a few. Partners forming a coalition are automatically selected given some business criteria and become active participants from the time the coalition is formed. Highly dynamic coalitions (HDCs) form a sub class of dynamic coalitions where the coalition formation and operation are strictly bound by time in order to provide a prompt reaction to some events. This type of dynamism poses the necessity of underlying security models and technologies allowing for automated coalition formation and operation. This paper presents a platform-driven approach to HDCs. It first defines a life cycle inherent to HDC formations, and then presents a platform-driven access control model that takes advantage of semantics of partners' requirements to provide interoperable access control to resources shared in a coalition. Coalition partners can achieve a high level of service interoperation by enhancing their access control requirements with semantics of usage, and interlinking their semantics using class relations based on standard ontology. ‡ Digital Ecosystems EU initiative-http://www.digitalecosystems.org; EU FP6 ECOLEAD project-http:// ecolead.vtt.fi possibility of providing combined services adapted to some client's requests. The dynamism in this case is often limited, as normally the coalition is static after it is formed, but sometimes the dynamism is extended to cover partner replacement during coalition operation. However, time scales for coalition formation and restructuring are long, thus allowing that these processes include some human intervention or complex
