网络安全适航性（CSA）在实际应用中的挑战
Challenges with the Application of Cyber Security for Airworthiness (CSA) in Real-World Contexts
AI总结：
针对网络安全适航性（CSA）在实际应用中面临的新法规追溯应用挑战，本文探讨了与时间、资金和人员资源相关的相互关联问题，并提出了潜在的缓解措施以促进有效实施。
摘要：
在商用、通用和军用航空航天领域，对计算机化技术的依赖日益增加，这带来了越来越多的潜在网络危害和攻击。因此，攻击向量的种类比以往任何时候都多。公认的良好实践标准，如DO 326A和ED 202A，试图通过为在役飞机提供网络安全指南来解决这一问题，尽管此类举措的实施工作仍处于早期阶段。根据先前对在役飞机的研究，作者确定关键挑战之一是将新法规追溯应用于现有设计。这可能会对时间、资金以及具备适当资格和经验的人员资源提出重大要求，而这些资源在军事环境中往往已经供应有限。作者此前探索了高效的合规方法，并取得了有前景的结果。仍然需要将这一追溯性挑战与影响CSA应用的其他关键因素一并考虑，以确定任何更多潜在的缓解措施，从而降低在航空领域有效且高效实施安全方法的障碍。这项工作探讨了围绕CSA实际应用的相互关联的挑战，以及如何克服这些挑战的开端。
英文摘要：
The ever increasing push towards reliance upon computerised technology in commercial, general, and military aerospace brings with it an increasing amount of potential cyber hazards and attacks. Consequently, the variety of attack vectors is greater than ever. Recognized Good Practice standards such as DO 326A and ED 202A attempt to address this by providing guidelines for cyber security on in-service aircraft, though implementation work for such initiatives is still in early stages. From previous work on in service aircraft, the authors have determined that one of the key challenges is that of the retrospective application of new regulations to existing designs. This can present significant requirements for time, money, and Suitably Qualified and Experienced Personnel resource, things which are often in already limited supply in military environments. The authors have previously explored efficient ways of approaching compliance, with promising results. There is still the need to consider this retroactivity challenge in tandem with other key factors affecting the application of CSA, in order to determine any more potential mitigating actions that could lower the barrier to effective and efficient implementation of secure approaches in the air domain. This work explores the interrelated challenges surrounding real-world applications of CSA and the beginnings of how these may be overcome.
