It was the end of my first day of vacation, a spectacular day spent riding the cable cars and hiking in the mountains near Chamonix, France.

I’ll admit it: I felt the urge to share some vacation pics via Facebook. After all, I’d spent most of the summer following my friends as they posted their vacation pictures, and I was eager to share in that feeling of community by sharing my own.

But then I flashed back to a presentation I gave to a group of executives two months earlier. Here, I had reminded them that because of their privileged access to financial systems and employee and customer data, they were prime targets for dedicated cybercriminals.
