HARMer:网络攻击自动化和评估

HARMer: Cyber-attacks Automation and Evaluation

Simon Yusuf Enoch, Zhibin Huang, Chun Yong Moon, Donghwan Lee, Myung Kil Ahn, Dong Seong Kim

摘要:

随着网络攻击事件的不断增长,重要的是要开发创新和有效的技术来评估和防御网络系统免受网络攻击。其中一个众所周知的技术是执行渗透测试,由一组安全专业人员(即红队)进行。众所周知,渗透测试可以有效地发现现有和新的漏洞,但是,安全评估的质量取决于红队成员的质量以及他们对渗透测试的时间和投入。在本文中,我们提出了一种新的自动化框架,名为“HARMer”的网络攻击生成,以解决与手动攻击执行的红队的挑战。我们提出的新框架,设计和实现是基于一个可扩展的图形安全模型,称为分层攻击表示模型(HARM)。(1)我们提出了自动化框架的要求和关键阶段。(2)我们提出了基于安全度量的攻击规划策略及其算法。(3)我们在一个真实的企业网和Amazon Web Services中进行实验。结果显示了框架的不同阶段如何相互作用,以模拟攻击者的操作。该框架将允许安全管理员以自动化的方式自动评估各种威胁和攻击的影响。

英文摘要:

With the increasing growth of cyber-attack incidences, it is important to develop innovative and effective techniques to assess and defend networked systems against cyber attacks. One of the well-known techniques for this is performing penetration testing which is carried by a group of security professionals (i.e, red team). Penetration testing is also known to be effective to find existing and new vulnerabilities, however, the quality of security assessment can be depending on the quality of the red team members and their time and devotion to the penetration testing. In this paper, we propose a novel automation framework for cyber-attacks generation named `HARMer' to address the challenges with respect to manual attack execution by the red team. Our novel proposed framework, design, and implementation is based on a scalable graphical security model called Hierarchical Attack Representation Model (HARM). (1) We propose the requirements and the key phases for the automation framework. (2) We propose security metrics-based attack planning strategies along with their algorithms. (3) We conduct experiments in a real enterprise network and Amazon Web Services. The results show how the different phases of the framework interact to model the attackers' operations. This framework will allow security administrators to automatically assess the impact of various threats and attacks in an automated manner.
