In today’s era of mega-breaches with thousands to millions of lost customer records or the hacking-of-everything it is safe to assume that the logical security of devices becomes almost more important than the physical protection around those assets. While it is true that the logical (in-) security of devices renders “remote attacks” (via a protocol such as TCP/IP, Ethernet, Bluetooth, or CDMA, GSM, etc.) possible, there is still an important defense layer that surrounds your device: the physical security.
To provide a little anecdote: on a recent flight into Washington, I put my little book and magazine on the seat next to me during the flight, and my cellphone on top of it. When the plane landed, it was a pretty heavy bump, and I saw my cellphone dropping on the ground, then sliding very fast toward the cockpit.
