Abstract

The Precision Time Protocol is essential for many time-sensitive and time-aware applications. However, it was never designed for security, and despite various approaches to harden this protocol against manipulation, it is still prone to cyber-attacks. Here Advanced Persistent Threats (APT) are of particular concern, as they may stealthily and over extended periods of time manipulate computer clocks that rely on the accurate functioning of this protocol. Simulating such attacks is difficult, as it requires firmware manipulation of network and PTP infrastructure components. Therefore, this paper proposes and demonstrates a programmable Man-in-the-Middle (pMitM) and a programmable injector (pInj) device that allow the implementation of a variety of attacks, enabling security researchers to quantify the impact of APTs on time synchronisation.
点到点时间同步网络上apt的实际实现
精确时间协议对于许多时间敏感和时间敏感的应用程序是必不可少的。然而,它从来都不是为了安全而设计的,尽管有各种方法来强化该协议以防止操纵,但它仍然容易受到网络攻击。在这里,高级持续威胁(APT)是特别值得关注的,因为它们可能会在很长一段时间内偷偷地操纵依赖于该协议准确功能的计算机时钟。模拟这种攻击很困难,因为它需要对网络和PTP基础设施组件进行固件操作。因此,本文提出并演示了可编程中间人(pMitM)和可编程注入器(pInj)设备,它们允许实施各种攻击,使安全研究人员能够量化apt对时间同步的影响。
