Caution: Turbulence Ahead
Bruce Schneier and Marcus Ranum look at the security landscape of the next 10 years.


Bruce Schneier
Predictions are easy and difficult. Roy Amara of the Institute for the Future once said: "We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run."

Moore's Law is easy: In 10 years, computers will be 100 times more powerful. My desktop will fit into my cell phone, we'll have gigabit wireless connectivity everywhere, and personal networks will connect our computing devices and the remote services we subscribe to. Other aspects of the future are much more difficult to predict. I don't think anyone can predict what the emergent properties of 100x computing power will bring: new uses for computing, new paradigms of com- munication. A 100x world will be different, in ways that will be surprising.

But throughout history and into the future, the one constant is human nature. There hasn't been a new crime invented in millennia. Fraud, theft, impersonation and counterfeiting are perennial problems that have been around since the beginning of society. During the last 10 years, these crimes have migrated into cyberspace,

and over the next 10, they will migrate into whatever computing, communications and commerce platforms we're using.

The nature of the attacks will be different: the targets, tactics and results. Security is both a trade-off and an arms race, a balance between attacker and defender, and changes in technology upset that balance. Technology might make one particular tactic more effective, or one particular security technology cheaper and more ubiquitous. Or a new emergent application might become a favored target.

I don't see anything by 2017 that will fundamentally alter this. Do you?
