摘要:

信息物理系统(CPS)由各种嵌入式子系统组成,需要专门的软件、固件和硬件来与系统的其余部分协调。这些多层次的集成暴露了易受攻击媒介影响的攻击面,这些攻击媒介需要新的架构方法来有效防范。提出了一种应用于飞行控制系统的多级层次监控架构网络安全方法。然而,本文中提出的原则适用于任何CPS。此外,这些监视器的实时性允许适应性安全,这意味着它们可以减轻在线攻击的可能类别。这就形成了一种吸引人的螺栓连接解决方案,它独立于不同的系统设计。因此,采用这样的监视器导致安全关键CPS的增强的系统弹性和可靠性。

英文摘要:

Cyber-physical systems (CPS) are composed of various embedded subsystems and require specialized software, firmware, and hardware to coordinate with the rest of the system. These multiple levels of integration expose attack surfaces which can be susceptible to attack vectors that require novel architectural methods to effectively secure against. We present a multilevel hierarchical monitor architecture cybersecurity approach applied to a flight control system. However, the principles present in this paper apply to any CPS. Additionally, the real-time nature of these monitors allow for adaptable security, meaning that they mitigate against possible classes of attacks online. This results in an appealing bolt-on solution that is independent of different system designs. Consequently, employing such monitors leads to strengthened system resiliency and dependability of safety-critical CPS.
