分布式系统中的历史敏感与未来敏感的安全方法

History-sensitive versus future-sensitive approaches to security in distributed systems

Alejandro Mario Hernandez, Flemming Nielson

摘要:

我们认为使用面向方面的技术作为一种灵活的方式来处理分布式系统中的安全策略。最近的工作建议使用方面来分析程序的未来行为,并在此基础上做出访问控制决策;这给人的感觉是处理信息流,而不仅仅是访问控制。在本文中,我们表明,这是有益的,以增加这种方法与基于历史的组件是传统的方法,在参考监视器为基础的方法,强制访问控制。我们的发展是在一个面向方面的协调语言,旨在描述尽可能优雅的Bell-LaPadula政策。此外,生成的语言能够结合历史和未来敏感的策略,提供更大的灵活性和功能。

英文摘要:

We consider the use of aspect-oriented techniques as a flexible way to deal with security policies in distributed systems. Recent work suggests to use aspects for analysing the future behaviour of programs and to make access control decisions based on this; this gives the flavour of dealing with information flow rather than mere access control. We show in this paper that it is beneficial to augment this approach with history-based components as is the traditional approach in reference monitor-based approaches to mandatory access control. Our developments are performed in an aspect-oriented coordination language aiming to describe the Bell-LaPadula policy as elegantly as possible. Furthermore, the resulting language has the capability of combining both history- and future-sensitive policies, providing even more flexibility and power.
