网络弹性:通过设计还是通过干预?

Cyber Resilience: by Design or by Intervention?

Alexander Kott, Maureen S. Golan, Benjamin D. Trump, Igor Linkov

摘要:

“通过设计实现网络弹性”一词越来越受欢迎。在这里,网络弹性指的是系统抵抗、最小化和减轻由对计算和通信设备的系统或网络的成功网络攻击引起的降级的能力。有些人使用“设计”一词,认为系统必须以可证明的任务保证方式设计和实施,系统的内在属性确保网络对手无法造成有意义的降级。其他人建议系统应该包括一个内置的自主智能代理,负责思考和行动,以持续观察,检测,最小化和修复网络退化。在所有情况下,“通过设计”这一限定词都表明,复原力的来源在某种程度上是系统结构和运作所固有的。那么,另一种弹性是什么呢?显然,必须有另一种类型的弹性,否则“通过设计”这个限定词的目的是什么?实际上,虽然较少提及,但存在一种称为“干预复原力”的替代形式的复原力。“在这篇文章中,我们探讨了设计弹性和干预弹性的差异和相互依赖。

英文摘要:

The term "cyber resilience by design" is growing in popularity. Here, by cyber resilience we refer to the ability of the system to resist, minimize and mitigate a degradation caused by a successful cyber-attack on a system or network of computing and communicating devices. Some use the term "by design" when arguing that systems must be designed and implemented in a provable mission assurance fashion, with the system's intrinsic properties ensuring that a cyber-adversary is unable to cause a meaningful degradation. Others recommend that a system should include a built-in autonomous intelligent agent responsible for thinking and acting towards continuous observation, detection, minimization and remediation of a cyber degradation. In all cases, the qualifier "by design" indicates that the source of resilience is somehow inherent in the structure and operation of the system. But what, then, is the other resilience, not by design? Clearly, there has to be another type of resilience, otherwise what's the purpose of the qualifier "by design"? Indeed, while mentioned less frequently, there exists an alternative form of resilience called "resilience by intervention." In this article we explore differences and mutual reliance of resilience by design and resilience by intervention.
