“During an in-depth policy discussion at the 2017 RSA Conference in San Francisco, former special adviser on cybersecurity to President Barack Obama, Michael Daniel, outlined the three main models for thinking about national defense: Border security, missile defense and deterrence, aka mutually assured destruction. Unfortunately, he said, none of these are sufficient to meet the cybersecurity challenge.
‘We tend to think of cybersecurity at the national level like border security; we also have this image of cybersecurity as missile defense or defense against aircraft; we have this idea of deterrence,’ specifically nuclear deterrence, Daniel said. ‘I think all three of those models are wrong.’”
