Bruce Schneier on the power of technology in a security context:
A core, not side, effect of technology is its ability to magnify power and multiply force — for both attackers and defenders. One side creates ceramic handguns, laser-guided missiles, and new-identity theft techniques, while the other side creates anti-missile defense systems, fingerprint databases, and automatic facial recognition systems.
The problem is that it’s not balanced: Attackers generally benefit from new security technologies before defenders do. They have a first-mover advantage. They’re more nimble and adaptable than defensive institutions like police forces. They’re not limited by bureaucracy, laws, or ethics. They can evolve faster. And entropy is on their side — it’s easier to destroy something than it is to prevent, defend against, or recover from that destruction.
For the most part, though, society still wins. The bad guys simply can’t do enough damage to destroy the underlying social system. The question for us is: can society still maintain security as technology becomes more advanced?
I don’t think it can.
