This isn't really a new conversation
We have had these conversations before, (just substitute "personal laptop" for "personal mobile device", and the dialog is deja vu)
Remember these beauties:
"Why can't I use my Windows XP Home laptop on the corporate network? It has XP just like my desktop you gave me!"
"What do you mean I can't use a personal Inkjet printer? It's not like you guys are paying for it! It is way more convenient to me that having to walk two cubicles down to the networked printer."
I support a client that is using Multiple Android version smartphones, but the company is paying for them, and the controls are in place. If they were to use BYOD, the security policy would require an PIN Code to unlock, not just a swipe guesture, the device can be remotely wiped if need be and/or have certain features shutdown. I do agree with the author that wholesale denial by IT is not the answer, but I also agree that Leadership CANNOT be in charge of such a program, as most have no concept of what mobile security entails.
