Seems a bit severe... e.g. if you don't allow bluetooth, then how are you supposed to have a safe hands-free blackberry phonecall while driving, without messing around with wired headsets? ;-)
But definitely some worthwhile food for thought here about best practices for BES lockdowns:
Demilitarised Zone most secure option for BlackBerry device: "...NTA recommends the following security checklist for BlackBerry users and organisations:
- Enable content protection - This encrypts the hand held data. The device should be set at 0 (which is a 16-bit elliptic curve key).
- Password policy - The forbidden password option should be set, disallowing users to choose a simple key pattern. The minimum password length setting should be used to enforce a key of nine characters and a maximum password attempt should be set at a recommended five times.
- Application control - disallows third party application downloads and should only allow approved software.
- Other messaging services - functions other than those necessary should be disabled which prevents the use of peer-to-peer messaging such as ICQ and Google Talk.
- Do not use Bluetooth - this function should be disabled due to its inherent security vulnerabilities..."
