Mitnick. They have really opened my eyes to how vulnerable we are. Yes, I know that some of you think that I am already overzealous about security, but when you realize how easy it is to bypass security, whether using social techniques or technology hacks, it is scary. If you work with technology or lead an organization, I highly recommend reading Kevin’s books.

Also, last week Tim Fehlman on Daily Cup of Tech, focused on security, his Security Week Windup is a great resource.

Speaking of security, while walking into the lobby of a local Caribbean restaurant, Mango Mike’s, I came across an interestingly placed server cabinet…
