Building an Effective Mobile Security Policy

Mobile PDA devices are inherently insecure, a fact easily recognizable
from the lack of any realistic security standard. An effective method of
ensuring mobile device security is to attempt to build an enforceable
mandatory access control system to make certain that only authorized
users are able to access your PDA and its confidential contents.
The best way to ensure that security is maintained is to make it centrally
controlled by the administration within your organization, as
opposed to the individual user. If a device is stolen or compromised, then
it is that much more difficult for a hacker to gain access to the device or
collect information or passwords.
