Should we fear hackers? Intention is at the heart of this discussion.

The perfect PIN is not four digits and not associated with your life, like an old telephone number. It's something easy for you to remember and hard for other people to guess.

Companies spend millions of dollars on firewalls and secure access devices, and it's money wasted because none of these measures address the weakest link in the security chain: the people who use, administer and operate computer systems

I got so passionate about technology. Hacking to me was like a video game. It was about getting trophies. I just kept going on and on, despite all the trouble I was getting into, because I was hooked.

If you go to a coffee shop or at the airport, and you're using open wireless, I would use a VPN service that you could subscribe for 10 bucks a month. Everything is encrypted in an encryption tunnel, so a hacker cannot tamper with your connection.

Garbage can provide important details for hackers: names, telephone numbers, a company's internal jargon.

But a lot of businesses out there don't see the return on investment, they look at it as a liability, and until they can understand that proactive security actually returns, gives them a return on investment, it's still a hard sell for people.
