When to turn to nature-inspired solutions for cyber systems
Nature-inspired algorithms have given us elegant solutions across a broad spectrum of design challenges. Efforts within cyber systems are equally replete with cases in which algorithms either adapted from, or at least inspired by, observations of natural biological systems, ranging from efficient packet routing, to anomaly detection, and beyond. We discuss how natural systems achieve robust and efficient solutions and the implications this ontology has for helping inform how and when it may be most fruitful to exploit them, and when instead we should probably forego analogy and instead build tailored tools from scratch. Further, we consider how it might be possible to move beyond this case-by-case analogy paradigm to exploit the deeper design elements that make natural systems successful at converging on sufficient solutions and then employ these more fundamental tools in purposeful design. In particular, we consider the design challenges faced when trying to borrow from nature to inform the areas of cyber security and resilience.
