You are human, that’s why.
We live in an age in which the evolution of our species is lagging behind our technological progress. Where Moore’s law meets, greets, and SYN-ACKs the theory of evolution, then skips into quantum computing.
We can identify adversaries by their behavior both in real life and online. Today’s breaches are being caused by advanced persistent threats; behind these threats are people. They are mapping out your strengths. Your vulnerabilities. The way you do business.
“But” *shrug*,”you don’t know what you don’t know”, right? Right! We are just wired that way: unless there’s a personal event that happens abruptly and you find it morally offensive within your attention span. Is that an efficient way to run a business, though?
For a true feeling of security that you can measure, invest in some technology that can detect behavior.
