通信保护策略异常的分类与分析

Classification and Analysis of Communication Protection Policy Anomalies

Fulvio Valenza, Cataldo Basile, Daniele Canavese, Antonio Lioy

摘要:

本文提出了一种分类的异常,可能会出现在设计或实施通信保护策略。连同已经知道的内部和内部的政策异常类型,我们引入了一个新的类别,技术间的异常,有关的安全控制实现不同的技术,在同一个网络节点和不同的网络节点之间。通过实证评估,我们证明了检测这种新的异常类的实际意义。此外,本文介绍了一个正式的模型,基于一阶逻辑规则,分析网络拓扑结构和安全控制在每个节点,以确定检测到的异常,并提出解决这些问题的策略。该形式化模型具有可管理的计算复杂性,其实现显示出优异的性能和良好的可扩展性。

英文摘要:

This paper presents a classification of the anomalies that can appear when designing or implementing communication protection policies. Together with the already known intra- and inter-policy anomaly types, we introduce a novel category, the inter-technology anomalies, related to security controls implementing different technologies, both within the same network node and among different network nodes. Through an empirical assessment, we prove the practical significance of detecting this new anomaly class. Furthermore, this paper introduces a formal model, based on first-order logic rules that analyses the network topology and the security controls at each node to identify the detected anomalies and suggest the strategies to resolve them. This formal model has manageable computational complexity and its implementation has shown excellent performance and good scalability.
