The Americans are the most gullible, because they don't like to deny co-workers' requests.

A company can spend hundreds of thousands of dollars on firewalls, intrusion detection systems and encryption and other security technologies, but if an attacker can call one trusted person within the company, and that person complies, and if the attacker gets in, then all that money spent on technology is essentially wasted.

Choosing a hard-to-guess, but easy-to-remember password is important!

I did get a huge endorphin rush when I was able to crack a system because it was like a video game.

I use Mac. Not because it's more secure than everything else - because it is actually less secure than Windows - but I use it because it is still under the radar. People who write malicious code want the greatest return on their investment, so they target Windows systems. I still work with Windows in virtual machines.

For the average home-user, anti-virus software is a must.

I get hired to hack into computers now and sometimes it's actually easier than it was years ago.
