IT managers know the movies get it wrong. A teenager with a laptop cannot crack multiple layers of encryption — unless that laptop is connected to a supercomputer somewhere and the teenager can afford to wait a few billion years.
Encryption works. It works so well that even the government gets stymied, as demonstrated by the lengths to which the FBI went to access an iPhone used by one of the San Bernardino, Calif., shooters.
So in the face of ever more damaging stories about data breaches, why aren’t all government agencies encrypting everything, everywhere, all the time?
Encryption can be costly and time consuming. It can also be sabotaged by users and difficult to integrate with legacy applications.
