摘要:

攻击图是一种用于枚举攻击者可以在组织网络中执行的可能路径的方法。MulVAL是用于自动生成攻击图的已知开源框架。MulVAL的默认建模有两个主要缺点。首先,它缺乏对网络协议漏洞的表示,因此不能用于对常见的网络攻击(如ARP中毒、DNS欺骗和SYN泛洪)进行建模。其次,它不支持无线和总线通信等高级类型的通信,因此不能用于对包括物联网设备或工业组件的网络进行网络攻击建模。在本文中,我们提出了一个扩展的网络安全模型MulVAL:(1)考虑物理网络拓扑结构,(2)支持短距离通信协议(例如,蓝牙),(3)对网络协议的设计中的漏洞进行建模,以及(4)对特定的工业通信体系结构进行建模。使用所提出的扩展,我们能够模拟多种攻击技术,包括:欺骗,中间人,拒绝服务,以及对高级类型的通信的攻击。我们证明了所提出的模型在一个测试平台上实现了一个简化的网络架构,包括IT和工业组件。

英文摘要:

An attack graph is a method used to enumerate the possible paths that an attacker can execute in the organization network. MulVAL is a known open-source framework used to automatically generate attack graphs. MulVAL's default modeling has two main shortcomings. First, it lacks the representation of network protocol vulnerabilities, and thus it cannot be used to model common network attacks such as ARP poisoning, DNS spoofing, and SYN flooding. Second, it does not support advanced types of communication such as wireless and bus communication, and thus it cannot be used to model cyber-attacks on networks that include IoT devices or industrial components. In this paper, we present an extended network security model for MulVAL that: (1) considers the physical network topology, (2) supports short-range communication protocols (e.g., Bluetooth), (3) models vulnerabilities in the design of network protocols, and (4) models specific industrial communication architectures. Using the proposed extensions, we were able to model multiple attack techniques including: spoofing, man-in-the-middle, and denial of service, as well as attacks on advanced types of communication. We demonstrate the proposed model on a testbed implementing a simplified network architecture comprised of both IT and industrial components.
