The vast majority of companies are more exposed to cyberattacks than they have to be. To close the gaps in their security, CEOs can take a cue from the U.S. military. Once a vulnerable IT colossus, it is becoming an adroit operator of well-defended networks. Today the military can detect and remedy intrusions within hours, if not minutes.
