基于属性的访问控制策略挖掘

Mining Attribute-based Access Control Policies

Zhongyuan Xu, Scott D. Stoller

摘要:

基于属性的访问控制(ABAC)提供了高度的灵活性,可促进安全性和信息共享。ABAC策略挖掘算法有可能显著降低迁移到ABAC的成本,通过部分自动化从访问控制列表(ACL)策略或基于角色的访问控制(RBAC)策略与附带的属性数据开发ABAC策略。提出了一种基于ABAC的策略挖掘算法。据我们所知,它是第一个ABAC策略挖掘算法。我们的算法迭代元组在给定的用户权限关系,使用选定的元组作为种子构建候选规则,并试图概括每个候选规则,以覆盖额外的元组在用户权限关系中的属性表达式中的约束条件,取代合取。我们的算法试图通过合并和简化候选规则来改进策略,然后选择最高质量的候选规则包含在生成的策略中。

英文摘要:

Attribute-based access control (ABAC) provides a high level of flexibility that promotes security and information sharing. ABAC policy mining algorithms have potential to significantly reduce the cost of migration to ABAC, by partially automating the development of an ABAC policy from an access control list (ACL) policy or role-based access control (RBAC) policy with accompanying attribute data. This paper presents an ABAC policy mining algorithm. To the best of our knowledge, it is the first ABAC policy mining algorithm. Our algorithm iterates over tuples in the given user-permission relation, uses selected tuples as seeds for constructing candidate rules, and attempts to generalize each candidate rule to cover additional tuples in the user-permission relation by replacing conjuncts in attribute expressions with constraints. Our algorithm attempts to improve the policy by merging and simplifying candidate rules, and then it selects the highest-quality candidate rules for inclusion in the generated policy.
