网络物理系统越来越多地应用于日常应用，包括关键应用。操作系统最初设计为物理隔离运行（因此没有或很少有网络安全防御），而信息技术系统默认是联网的，这种集成极大地增加了由此产生的复合系统的网络攻击面。因此，网络物理系统的安全态势评估以及防御机制的有效性和效率评估变得至关重要。不幸的是，即使有可能，也不建议在现实世界的网络物理系统中测试网络安全。因此，使用测试平台是一种必要的选择。这项工作调查了五个主要应用领域的网络物理测试台，着眼于确定关键功能，随后将其用作定义具有网络安全态势评估能力的未来网络物理测试台需求的过程的输入。然后，我们提出了下一代网络靶场的参考架构，即网络物理靶场。
Cyber-physical systems are being increasingly employed in everyday applications, including critical ones. This integration of operational technology systems, originally designed to operate in physical isolation -hence with no or little cyber security defences- with information technology systems, by default meant to be networked, dramatically increases the cyber-attack surface of the resulting composite systems. Thus, the assessment of the security posture of cyber-physical systems, as well as the evaluation of the effectiveness and efficiency of the defensive mechanisms become of paramount importance. Unfortunately, testing cyber security in live real-world cyber-physical systems is not advisable, even when it is possible; hence, the use of testbeds is a necessary alternative. This work surveys cyber-physical testbeds in five major application domains, with an eye towards identifying key features to be subsequently used as input to the process of defining requirements for future cyber-physical testbeds with cyber security posture assessment capability. We then propose a reference architecture for the next generation of cyber ranges, namely the cyber-physical ranges.
