Infosec: Can you be too paranoid?

Interesting column from Mark Burnett at Security Focus. Here are some examples of Mark's paranoia:

• I keep my PC's turned around so I can tell if anyone has installed a hardware keylogger.
  
• I never check in luggage when I fly.
  
• I do my Internet browsing from a locked down VMWare box that has no rights on my network.
  
• I use terrafly.com to see what others might be able to see about my home.
  
• It takes five passwords to boot up my laptop and check my e-mail.
  
• One of those passwords is over 50 characters long.
