It's widely publicised that Obama has a blackberry, but it isn't clear to me what security settings are employed by the NSA or what private businesses can learn from his configuration?

What is known, or what can you infer about a secure Blackberry deployment of such a critical nature?

I'm pretty sure its the NSA's job (not Secret Service) to secure computing devices, but I could be wrong there. –  AviD Nov 21 '10 at 12:18
    
@AviD Secret Service likely borrowed someone from the NSA as a consultant. –  Polynomial Sep 22 '12 at 9:24

From what I've seen, he simply isn't allowed to use it for official purposes. He has to use a secure device instead.

Thanks, that is a cool link to know about. I'd still be interested in the settings that he uses for his Blackberry that private industry can emulate. –  makerofthings7 Nov 23 '10 at 17:45

2G communications is proven to be very unsafe for both voice and data.

GPRS/UMTS use A5/3 encryption and the encryption for that has not been broken. It's possible that his blackberry only uses GPRS/UMTS networks

I'm sure he has the same policies that are applicable to the DoD.

Not much. I expect the measures are extreme in complexity and cost and appropriate for heads of state or equivelent value individuals.

In short that Blackberry may cost $1.000.000 USD to secure, who else could afford to pay that much?

One person's sequester is another person's blackberry. –  Deer Hunter Jun 16 '13 at 8:01
