检查安全策略合规性

Checking Security Policy Compliance

Vaibhav Gowadia, Csilla Farkas, Michiharu Kudo

摘要:

确保各组织遵守联邦法规是一个日益令人关切的问题。本文提出了一个框架和方法来验证是否实现低级别的安全策略是符合一个高级别的安全策略。我们的合规性检查框架基于组织和安全元数据,以支持将高级概念细化为实现特定实例。我们的工作使用精化演算的结果来表达有效的精化模式和它们的属性。直观地说,如果存在从高级安全策略到低级安全策略的有效细化路径,则低级安全策略符合高级安全策略。我们的模型能够检测违反安全策略,未能履行义务,以及能力和模式冲突。

英文摘要:

Ensuring compliance of organizations to federal regulations is a growing concern. This paper presents a framework and methods to verify whether an implemented low-level security policy is compliant to a high-level security policy. Our compliance checking framework is based on organizational and security metadata to support refinement of high-level concepts to implementation specific instances. Our work uses the results of refinement calculus to express valid refinement patterns and their properties. Intuitively, a low-level security policy is compliant to a high-level security policy if there is a valid refinement path from the high-level security policy to the low-level security policy. Our model is capable of detecting violations of security policies, failures to meet obligations, and capability and modal conflicts.
