Snooping or Security?

As I follow the press on digital safety one theme that has been coming up over and over again lately is the coming risk of cyberwarfare between the United States and hackers, terrorists and even other countries. The other theme is that as we implement cybersecurity the line between surveillance and snooping is getting razor thin. Thin enough, in fact, that Einstein 3, the latest iteration of the Federal government's intrusion detection program, has aroused privacy concerns because it can examine the content of email. It is something that we all need to know more about as security experts whether it is the government or private enterprise that should be doing the snooping and exactly what kind of snooping is allowed.
