This paper presents a comparative cyber security resilience estimation of shipboard radars that are implemented on two oil/chemical tankers certified as SOLAS ships. The estimated radars were chosen from the same manufacturer, but belonged to different generations. The estimation was conducted by means of ships' crew interviews and computational testing of the radars using a widely deployed vulnerability scanning software tool. The identified cyber threats were analysed qualitatively in order to gain a holistic understanding of cyber risks threatening shipboard radar systems. The results obtained experimentally indicate that potential cyber threats mainly relate to maintenance of the radars' underlying operating system, suggesting the need for regulatory standardisation of periodic cyber security testing of radar systems.

迈向网络安全的舰载雷达

本文介绍了在两艘被认证为 SOLAS 船舶的油/化学品油轮上实施的船载雷达的比较网络安全弹性评估。估计的雷达来自同一制造商，但属于不同的世代。估计是通过船员访谈和使用广泛部署的漏洞扫描软件工具对雷达的计算测试进行的。对已识别的网络威胁进行定性分析，以全面了解威胁舰载雷达系统的网络风险。实验结果表明，潜在的网络威胁主要与雷达底层操作系统的维护有关，这表明需要对雷达系统的定期网络安全测试进行监管标准化。
