Abstract

Cyber situational awareness is key to mitigating the impacts of cyber threats. However, maritime falls short of its comparative industries, with very little attention given to cyber threats despite the growing concern. In this paper, we explore the use of visualisations as a way to improve the situational awareness of non-experts onboard ships. We designed a visualisation tool with focus on systems that are accessible once onboard. In order to elicit requirements for our visualisations, we conducted semi-structured interviews with experts. We further created a synthetic dataset of attacks that target the systems of ships, which we used to assess the usability of our visualisation. In order to evaluate our visualisations, we conducted a user study with both expert and non-expert users. Our results show that non-expert participants were able to accurately and efficiently detect synthetic attacks targeting ships in an experimental setting, and they were able to use the visualisation to consider what the consequences of these attacks might be. Expert evaluations further suggest the visualisation has merit as a training tool for raising awareness among maritime employees.
增强海上网络态势感知:面向非专家的网络安全可视化
网络态势感知是减轻网络威胁影响的关键。然而,与同行业相比,海运业仍存在差距,尽管人们对网络威胁的担忧日益加剧,但海运业对网络威胁的关注却很少。在本文中,我们探讨了使用可视化技术来提高船上非专家的态势感知能力。我们设计了一个可视化工具,重点关注一旦上船就可以访问的系统。为了引出对可视化的需求,我们对专家进行了半结构化的访谈。我们进一步创建了一个针对船舶系统的攻击的合成数据集,我们用它来评估我们可视化的可用性。为了评估我们的可视化效果,我们对专家和非专业用户进行了用户研究。我们的研究结果表明,非专业参与者能够在实验环境中准确有效地检测到针对船只的合成攻击,并且他们能够使用可视化来考虑这些攻击可能带来的后果。专家评估进一步表明,可视化作为提高海事员工意识的培训工具具有优点。
