Today, Calce said the bandwidth available to the average user is amazing, and a little frightening. No longer do hackers need to exploit complex networks; they can choose from millions of average users with broadband connections and little protection. “So much readily available bandwidth is not a good thing,” said Calce.

He's now very restricted, by choice, in his online activities. He doesn't believe in Twitter – “I'm going to get water, so what?” – and he's on Facebook primarily to keep in touch with old high school friends. But he doesn't update his status “every two minutes” or put too much information out there for people to read. He doesn't do online banking, he doesn't carry a debit or credit card, and he doesn't shop online.

The risks, he said, are just too great, and the same inherent vulnerabilities in the way the Internet was constructed that he was able to exploit are still there. Unless and until they're fixed, Calce said he doesn't feel safe putting too much information online.

Of course, there's also the question, do we need to share all that we do anyways?
