"It is not the strongest or the most intelligent who will survive but those who can best manage change" – a quote, often attributed to Charles Darwin, (turns out it was actually a paraphrase by some accounts), but that aside, a lesson in evolutionary biology turns out to be incredibly useful in the realm of healthcare security. When examining the rapid speed at which the threat landscape for healthcare is changing and combining it with the traditionally slow-to-adapt nature of the healthcare industry in general, the problem's pretty clear. It's a different threat world nowadays.
