摘要:

评估网络安全是一项复杂而艰巨的任务。攻击图已被提出作为一种工具,以帮助网络管理员了解其网络的潜在弱点。然而,一个问题还没有得到解决,以前的工作在这个问题上,即,如何实际执行和验证的攻击路径从攻击图的分析。在本文中,我们提出了一个完整的PDDL表示的攻击模型,并实现集成到一个渗透测试工具的计划。这允许自动生成渗透测试场景的攻击路径,并通过对真实目标网络执行相应的操作(包括漏洞利用)来验证这些攻击。我们提出了一种算法,用于将渗透测试工具中存在的信息转换到规划域,并展示了如何使用当前规划器解决攻击图的可扩展性问题。我们包括我们的解决方案的性能分析,显示我们的模型如何扩展到中型网络,以及当前渗透测试工具中可用的操作数量。

英文摘要:

Assessing network security is a complex and difficult task. Attack graphs have been proposed as a tool to help network administrators understand the potential weaknesses of their network. However, a problem has not yet been addressed by previous work on this subject; namely, how to actually execute and validate the attack paths resulting from the analysis of the attack graph. In this paper we present a complete PDDL representation of an attack model, and an implementation that integrates a planner into a penetration testing tool. This allows to automatically generate attack paths for penetration testing scenarios, and to validate these attacks by executing the corresponding actions -including exploits- against the real target network. We present an algorithm for transforming the information present in the penetration testing tool to the planning domain, and show how the scalability issues of attack graphs can be solved using current planners. We include an analysis of the performance of our solution, showing how our model scales to medium-sized networks and the number of actions available in current penetration testing tools.
