- Title
Relationship‐based access control: More than a social network access control model.

- Abstract
In a computer system, access control refers to the mechanisms the system use to decide whether to grant or reject access to its resources. Access control decisions in social media services, such as Facebook, Twitter, Research Gate, or LinkedIn, are determined in large part by policies that can be described in terms of the relationships among the individuals potentially affected by the decision. The premise behind a larger interest in Relationship‐based Access Control (ReBAC) is that besides social media services, social and other forms of relationships can be an effective abstraction for describing and implementing access control policies. The aim of this paper is to present an overview of ReBAC from the point of view of the types of policies that have motivated the access control research community to develop different ReBAC systems. We also review and reflect on what it would take to implement and administer an ReBAC system. This article is categorized under: Fundamental Concepts of Data and Knowledge > Information RepositoriesFundamental Concepts of Data and Knowledge > Data ConceptsApplication Areas > Society and Culture Zooming in a portion of a network of profesional relationships (relations between the cicles) as well as other relations between subjects and objects of a system to protect. Relationship‐based access control policies are defined as paths between nodes that the network must have. For example, the secretary at any department has access to salary information of any employee that reports to the manager of the department: Bob can access salary information of Doug because of the paths (Bob, secretary_at, Wireless Dept) and (Doug, reports_to, Alice, manages, Wireless Dept).
