Abstract

Role Based Access Control (RBAC) is the de facto standard in access control models, and is widely used in many applications and organizations of all sizes. However, the task of finding an appropriate set of roles, called role engineering, remains the most challenging roadblock to effective deployment. In recent years, this problem has attracted a lot of attention, with several bottom-up approaches being proposed, under the field of role mining. However, most of these theoretical approaches cannot be directly applied to large scale datasets, which is where they are most necessary. Therefore, in this paper, we look at how to make role mining practical and usable for actual deployment. We propose a six steps methodology that makes role mining scalable without sacrificing on utility and is agnostic to the actual role mining technique used. The experimental evaluation validates the viability of our approach.
角色工程:从理论到实践
基于角色的访问控制(RBAC)是访问控制模型中事实上的标准,广泛应用于各种规模的应用程序和组织中。然而,寻找一组合适的角色(称为角色工程)的任务仍然是有效部署的最具挑战性的障碍。近年来,这一问题引起了人们的广泛关注,在角色挖掘领域提出了几种自下而上的方法。然而,这些理论方法中的大多数不能直接应用于大规模数据集,而这正是它们最需要的地方。因此,在本文中,我们着眼于如何使角色挖掘在实际部署中变得实用和可用。我们提出了一种六步方法,使角色挖掘在不牺牲效用的情况下具有可扩展性,并且与实际使用的角色挖掘技术无关。实验结果验证了该方法的可行性。
