Towards a Systematic View on Cybersecurity Ecology

Current network security systems are progressively showing their limitations. One credible estimate is that only about 45% of new threats are detected. Therefore it is vital to find a new direction that cybersecurity development should follow. We argue that the next generation of cybersecurity systems should seek inspiration from nature. This approach has been used before in a first generation of cybersecurity systems; however, since then cyber threats and environment have evolved significantly, and accordingly the first-generation systems have lost their effectiveness. A next generation of bio-inspired cybersecurity research is emerging, but progress is hindered by the lack of a framework for mapping biological security systems to their cyber analogies. In this paper, using terminology and concepts from biology, we describe a cybersecurity ecology and a framework that may be used to systematically research and develop bio-inspired cybersecurity.
